Abstract
ABSTRACT OF THE DISCLOSURE:
A control panel contains four control levers. A
control valve having a valve slide capable of sliding in a valve sleeve is assigned to each control lever. An electric motor on whose drive shaft a bevel gear is mounted in a rotationally solid manner is also provided for each control lever. The bevel gear engages with another bevel gear that is connected with a shaft journal in a rotational-ly solid manner. A follower pin is eccentrically mounted in the shaft journal; it passes through one end of a push rod and projects into a groove in a shaft journal passed through by the assigned control lever. In this manner, the two shaft journals are connected with each other through the follower pin in a rotational manner. The other end of the push rod is connected through a coupling with a piston rod that is in turn fastened to the valve slide. In the arrangement described above, the control valve can be actuated at any time either by the control lever or the electric motor. The simultaneous action of the control lever and the electric motor on the control valve is also possible without damage resulting thereby.

Description
~32~
The invention concerns an operating table with a patient support surface tiltable around longitudinal and transverse axes.
An operating table is described in the Swiss Patent 615,587, in which a patient support surface divided into sections is til-tably situated on a support column. The support column rests on a moveable table base. The individual sections of the patient support surface can be swung relative to each other around their transverse axes, in which case the pivoting movement is effected by hydraulic cylinders. The hydraulic cylinders are actuated by control valves that are located in a control panel. The control valves can be operated by con-trol levers projecting out of the control panel.
It is frequently desirable that the operating table, which is loca-ted in a sterile zone, can be operated from outside, i.e., to adjust the sections of the patient support surEace and/or the height of the latter. This is not possible with the familiar operating table.
The invention proposes to oEfer an operating -table that can be operated from outside of the sterile zone in which it is located, in which case the possibility of adjusting it from the operating table itself is simultaneously retained.
According to the present invention, there is provided an operating table having a patient support surface, said support surface being til-table about a longitudinal axis and about a transverse axis, said suppor-t surface being comprised of a plurality of segments, pivo-t means pivotally connecting each segment -to at least one other segment, individual drive means for tilting -the patient support surface about its longitudinal axis and about its transverse axis for pivoting each segment about its pivot means and relative to at leas-t one other segment, ., :, ~L~9;~2~
a control panel fixed to said table with a plurality of manually operable control levers for manually operating said individual drive means, actuator means for operating said individual drive means, and a remote control device having a sender and a receiver, said receiver having a driver stage with outputs for energizing said actuator means from a location remote from said table, characterized in that the ac-tuating means are electromagnetic devices and that each of the electromagnetic devices is functionally connected with one of the control levers to operate that lever from a remote location and is connected electrically with an output of the driver stage.
The object of the present invention is elucidated in greater detail in the following with reference to the drawings.

Figure 6 shows a section along the line VI-VI of Fig 3.
Figure 7 shows a section through a foot switch that is located in the base of the operating table.
And Figure ~ shows a section along the line VIII-VIII of Fig. 7.
The operating table shown in Fig. 1 has a patient support surface divided into sections 1, 2, 3, 4 and 5, which are pivotable relative to each other around the transverse axes 6, 7 and 8. The en-tire patient support surface can also be swung around a transverse axis 9. The section 2 rests on a support stand 10 that has a saddle 11, which is tiltable around the transverse axis 9 and around a longitudinal axis (not shown). The transverse axis 9 is supported in the upper part of a support column 12, which in turn projects upward ~rom a table base 13. The support column 12 is telescoping so that the patient support sur~ace i9 adjustable with regard to height. A control panel 1~ is 30 mounted on the support stand 10, the control levels 15-18 project out of it. The control panel 14 contains control valves that are not shown in Fig. 1, but are described in greater detail below.
Figure 2 shows the hydraulic system of the .~2~
operating table according to Fig. 1. The hydraulic system is comprised of a pump 20 that can be driven by an electric motor 19. The pu~p 20 delivers pressure oil from a reservoir 21 through a check valve 22 into a pressure oil accumulator 23 when the electric motor 19 is connected via a plug connection 24 to the a.c. network. The pressure in the pressure oil accumulator 23 can be read on a manometer 25.
An overpressure valve 26 prevents an excessive pressure from arising in the pressure reservoir ~3. The excess pressure oil returns via a return line 27 to the reservoir 21.
The pressure oil is conveyed through a pipeline 28 and a stand-by valve 29 and through a pipeline 31 into the control panel 14~ only a portion of which is shown schematically in Fig. 2. Four control valves, corresponding to the four control levers 15-18, are located in the control panel 14, each of which is assigned to one of the control levers 15-18.
Figure 2 shows only the two control valves 32 and 20 33 that are assigned to the control levers 15 and 18.
Pressure oil passes via the control valve 32 through an openable check valve 34 and a pipeline 35 to a drive cylinder 36 located in the support column 12 for raising the patient support surface when the control lever 25 18 is swung to the right in Fig. 2. If ~he control lever 18 is swung in the opposite direction, i.e., to the left, pressure oil passes through the control valve 32 into the openable check valve 34, by which the latter is opened, for lowering the patient support surface. The oil present in the working cylinder 3~ can flow back into the reservoir 21 through the pipeline 35, the opened check valve 34, the control valve 32 and the return line 27.
Analogously, the control valve 33 can be actuated with the control lever 15 and pressure oil can be fed to a ~L2~2~
drive cylinder 40, for exemple, connected to the control valve 33 via pipelines 41 and 42, for swinging the section 3 of the patient support surface around the transverse axis 7.
The control panel 1~ also contains four electric motors, each o~ which is assigned to one of the control levers 15-18 and the control valves 32, 33, and only those designated with 43 and 44 are shown in Fig. 2. A remote-control davice comprised of a sender ~5 and a receivex 46 is also provided. A driver stage 47 with, e.g., five outputs is connected to the receiver 46. The first output of the driver stage 47 is connected with an electric mo-tor 48, which serves for remote actuation of the stand-by valve 29.
Each of the other ~our outputs is connected with one of the electric motors 43 and 44 in the control panel 14. The lS remote-control signals generated by the sender 45 are fed to a luminous diode 49 and trans~ered as light signals to a photocell 50 and received in the receiver 46 and fed processed to the driver stage 47. The photocell 50 is located in the table base 13 (see Fig. 1).
Figure 3 shows a portion of the control panel 14 with the two control levers 17 and 18 in the rear view and Fig. 4 shows the control panel 1~ in the side view. It is evident ~rom Figs. 4 and 5 that the control panel 14 consists o~ four blocks 50-53. The ball bearings 5~ for the control levers 15-18 are located in the bearing block 50, where only the control lever 18 and the ball bearing 5~
assigned to it are shown in Fig. 5. ~he moveable valve slides 55 are supported in the control valve block 51 so as to slide in the longitudinal bores 80 of the valve bushing 79. The linkage block 52 is located betwaen the bearing block S0 and the control valve block 51 and encompasses a portion of a piston rod 56 that is displaceable only axially or a push rod 57 pivotably connected with the piston rod 56.
The connections for the drive cylinders 36 and ~0 and the ~4 ~"`, check valves, only one of which (95) is shown in Fig. 6, are located in the check valve block 53 mounted on the control valve block 51.
According to Fig. 5, the control lever 18 passes through a shaft journal 58 supported in the ball bearing 54.
A gear drive block 60 is inserted in a recess 59 of the bearing block 50. The gear drive block 60 has a first ball bearing 61 for an additional shaft journal 62 and a second ball bearing 63 for a bevel gear 66. The axis of rotation of ~he additional shaft journal 62 and that of the shaft journal 58 are located on a straight li~e. The shaft journal 62 has an added piece 65 concentric to the axis of rotation, on which an additional bevel gear 6~ that engages with the said bevel gear 66 is placed in a rotationally solid manner.
A portion of the electric motor 44 is located in a recess 67 concentric to the axis of rotation of the bevel gear 66 and is held therein by means of a setscrew 69. The drive axis 70 of the electric motor 44 extends through the bevel gear 66 and is connected with it in a rotationally solid manner.
A follower pin 72 that is eccentric to the axis of rotation i5 inserted in a bore 71 that runs parallel to the axis of rotation of the additional shaft journal 62. In order to illustrate the eccentric arrangement of the follower pin 72, the shaft journal 62 is shown in Fig. 5, turned by 90 around its axis of rotation. In the central position of the slide 55 shown in Fig. 5 the follower pin 72 ; would be at the same height as the axis of rotation of the shaft journal 62 and the eccentric arrangement could not be detected.
The follower pin 72 project~ out of the bore 7l in the direction to the shaft journal 58 and into a radial groove 73 of the shaft journal 58. In this manner, the two ~22'7~
shaft journals 58 and ~2 are connected together in a rotationally solid manner.
The follower pin 72 also extends through the one end of the push rod 57~ The latter ex-tends into a bore 74 in the linkage block 52 up to a coupling piece 75 -that connects the push rod 57 with the piston rod 56. The bore 7~ is expanded in the lower zone and a guide sleeve 76 for the piston rod is inserted into the expanded portion of the bore 74.
An aligning bore 77 is present in the control valve block 51, coaxial to the bore 74 in the linkage block 52. The lower end of the bore 77 is closed off by a screw plug 78. One of the valve sleeves 79 is inserted in a stationary manner in the middle region of the bore 77. The valve sleeve 79 has the longitudinal bore 80, in which the valve slide 55 connected with the piston rod 56 is slidably supported.
Three grooves 81, 82 and 83 ~hat extend along the periphery and are connected through radial bores 8~ with the longitudinal bore 80 are also present in the surface of -the valve ~ushing 79. Two channels 85 and 86 empty into the groove 81, of which only channel 85 is visible in Fig. 6.
Two channels 87 and 88 empty into the groove 83, of which only channel 87 is visible in Fig. 6. A feed channel 89, which is visible only in Fig. 6 and is connected to the pipeline 31, empties into the middle groove 82. The upper end of the longitudinal bore 80 is connected with a drainage channel 90 and the lower end of the longitudinal bore is connected with a drainage channel 91. The two drainage 30 channels 90 and 91 are connected to the re-turn line 38. The valve slide 55 had two peripheral ribs 92 that contribute to delimiting an annular space 93. In the middle position, in which the valve slide 55 is shown in Figs. 5 and 6, the annular space 93 is connected only through -the middle groove -- Ç --;, 2`, t;~a~
77 with the feed channel 89. If the valve glide 55 is brought into its lower position by ac-tuating the control lever 18, pressure oil passes from the annular space g3 in-to the channels 87 and 88, which were previously connected with the drain channel 91. Pressure oil passes through the channel 87 into a channel 94 in the check valve block 53 to a check valve 95 and through the pipeline 41 to the drive cylinder 40 (see Fig. 2). The excess oil flows ~rom the drive cylinder 40 through the pipeline 42 and the positively opened check valve 96 into a channel (not shown) in the check valve block 53 and from there into the channel 86 and through the assigned radial bore 84 into the drain channel 90 and then, as indicated above, back to the reservoir 21.
If the valve slide 55 is brought into its upper position, pressure oil passes from the annular space 93 into the channels 85 and 86. The pressure oil flows from the channel 86 through a channel (which is not shown, but corresponds to the channel 94 in the check valve block 53) through the check valve 96 and the pipeline 42 to the drive cylinder 40 tsee Fig. 2).
The excess oil flows from the drive cylinder 40 through the pipeline ~1 into the check valve 95, which is positively opened in the manner described in the following, the channels 94 and 87 into the drain channel 91 and from there back into the reservoir 21.
The positive opening of the check valve 95 takes place through a piston 97 with a pin 98. The piston 97 is held by a pressure spring 99 in its rest position shown in Fig. 6. When the valve slide 55 is moved upward, pressure oil also passes into the channel 85 and through a narrow channel 100 in the check valve block 53 into the working chamber on the left-hand side of the piston 97, with respect to Fig. 6. This causes the piston 97 with the pin 98 to be shifted to the right. The free end of the pin 98 strikes ,, . .,~
the moveable valve body 101 of the check valve 95, which causes it to be positively opened against the return force of a valve spring 102. The check valve 96 is positively opened in an analogous manner if the valve slide 55 is moved downward. The axial passage through the guide sleeve 76 is reduced twice and contains a supporting shoulder 103 on which a support plate 104 for a pressure spring 105 lies if the valve slide 55 is in the middle position. The other end of the pressure spring 105 rests on a support plate 105, which lies against the upper face of the valve sleeve 79 iE
the valvs slide 55 is not in the upper position. Openings 107 are provided in the support plate 106 so that oil can ~low out of the channels 85 and ~6 into the drain channel 90, even if the support plate 106 lies against the valve sleeve 79. The pressure spring 105 assures that the piston rod 56 and -the valve slide 55 are in the middle position shown in Figs. 5 and 6 if no external force acts on the control lever 18 and the electric motor 68 is not energized.
For example, if the control lever 18 is swung backward into the drawing plane of the Figure, the follower pin 72 is moved upward. This upward movement is transfered from the follower pin 72 to the push rod 57, the piston rod 56 and the valve slide 55. The upward movement of the valve slide 55 also causes the support plate 106 to be moved upward against the returning force of the pressure spring 105. The pressure spring 105 is thus still further pretensioned so that it moves the valve slide 55 and the control lever 18 back into the middle position iE an external force no longer acts on the control lever 18.
If the con-trol leYer 18 is actuated in the opposite direction, the ~ollower pin 72 moves downward.
This downward movement is transfered to the push rod 57, the piston rod 56 and the valve slide 55. The piston rod 56 has a support shoulder 108 on which the support plate 10~ lies ~2~22~
during the downward rnovement and is also shifted downwardO
The pressure spring 105 is thus pretensioned because the support plate 106 lies against the face of the valve sleeve 79. If an external force no longer acts on the control lever 18, the pressure spring 105 assures the return of the contro] lever 13 and the valve slide 55 to the middle position.
Movements analogous to the upward and downward movements described above are also effected if the electric motor 68 is energi~ed so that it generates a torque in one direction or another.
The valve slide 5~ and thus the drive cylinder collaborating with it can be controlled without additional measures at any time by actuating either the control lever 18 or the remote control device.
In order -to prevent the electric motor 44 from becoming overheated during more prologned energization and to save energy, a limit switch 68 is provided. The limit switch 68 acts with an axial projection 132 on the face of the shaft journal 62 adjacent to the bevel gear 64. The projection 132 extends over an angle of ca. 60 and is designed so that if the valve slide 55 is in the middle position the trip stop 133 of the limit switch 68 lies in the middle of the axial projection 132. As long as the trip stop 133 lies on the projection 132, the limit switch 68 is closed. A resistance 134 is switched parallel to the limit switch 68 and it is switched in series to the electric motor 44 (see Fi~. 2). After a rotation of ca. 30 in the shaft journal 62 in one direction or another, the trip stop 133 slips off the projection 132 and the limit switch 68 opens.
As a result, the series-switching of the resistance 134 to the electric motor 44 becomes active. The current through the electric motor 44 is reduced by the resistance 134 so sharply that the residual torque is precisely sufficient to f ,~

The operating table shown in Fig. 1 has a patient support surface divided into sections 1, 2, 3, 4 and 5, which are pivotable relative to each other around the transverse axes 6, 7 and 8. The en-tire patient support surface can also be swung around a transverse axis 9. The section 2 rests on a support stand 10 that has a saddle 11, which is tiltable around the transverse axis 9 and around a longitudinal axis (not shown). The transverse axis 9 is supported in the upper part of a support column 12, which in turn projects upward ~rom a table base 13. The support column 12 is telescoping so that the patient support sur~ace i9 adjustable with regard to height. A control panel 1~ is 30 mounted on the support stand 10, the control levels 15-18 project out of it. The control panel 14 contains control valves that are not shown in Fig. 1, but are described in greater detail below.
Figure 2 shows the hydraulic system of the .~2~
operating table according to Fig. 1. The hydraulic system is comprised of a pump 20 that can be driven by an electric motor 19. The pu~p 20 delivers pressure oil from a reservoir 21 through a check valve 22 into a pressure oil accumulator 23 when the electric motor 19 is connected via a plug connection 24 to the a.c. network. The pressure in the pressure oil accumulator 23 can be read on a manometer 25.
An overpressure valve 26 prevents an excessive pressure from arising in the pressure reservoir ~3. The excess pressure oil returns via a return line 27 to the reservoir 21.
The pressure oil is conveyed through a pipeline 28 and a stand-by valve 29 and through a pipeline 31 into the control panel 14~ only a portion of which is shown schematically in Fig. 2. Four control valves, corresponding to the four control levers 15-18, are located in the control panel 14, each of which is assigned to one of the control levers 15-18.
Figure 2 shows only the two control valves 32 and 20 33 that are assigned to the control levers 15 and 18.
Pressure oil passes via the control valve 32 through an openable check valve 34 and a pipeline 35 to a drive cylinder 36 located in the support column 12 for raising the patient support surface when the control lever 25 18 is swung to the right in Fig. 2. If ~he control lever 18 is swung in the opposite direction, i.e., to the left, pressure oil passes through the control valve 32 into the openable check valve 34, by which the latter is opened, for lowering the patient support surface. The oil present in the working cylinder 3~ can flow back into the reservoir 21 through the pipeline 35, the opened check valve 34, the control valve 32 and the return line 27.
Analogously, the control valve 33 can be actuated with the control lever 15 and pressure oil can be fed to a ~L2~2~
drive cylinder 40, for exemple, connected to the control valve 33 via pipelines 41 and 42, for swinging the section 3 of the patient support surface around the transverse axis 7.
The control panel 1~ also contains four electric motors, each o~ which is assigned to one of the control levers 15-18 and the control valves 32, 33, and only those designated with 43 and 44 are shown in Fig. 2. A remote-control davice comprised of a sender ~5 and a receivex 46 is also provided. A driver stage 47 with, e.g., five outputs is connected to the receiver 46. The first output of the driver stage 47 is connected with an electric mo-tor 48, which serves for remote actuation of the stand-by valve 29.
Each of the other ~our outputs is connected with one of the electric motors 43 and 44 in the control panel 14. The lS remote-control signals generated by the sender 45 are fed to a luminous diode 49 and trans~ered as light signals to a photocell 50 and received in the receiver 46 and fed processed to the driver stage 47. The photocell 50 is located in the table base 13 (see Fig. 1).
Figure 3 shows a portion of the control panel 14 with the two control levers 17 and 18 in the rear view and Fig. 4 shows the control panel 1~ in the side view. It is evident ~rom Figs. 4 and 5 that the control panel 14 consists o~ four blocks 50-53. The ball bearings 5~ for the control levers 15-18 are located in the bearing block 50, where only the control lever 18 and the ball bearing 5~
assigned to it are shown in Fig. 5. ~he moveable valve slides 55 are supported in the control valve block 51 so as to slide in the longitudinal bores 80 of the valve bushing 79. The linkage block 52 is located betwaen the bearing block S0 and the control valve block 51 and encompasses a portion of a piston rod 56 that is displaceable only axially or a push rod 57 pivotably connected with the piston rod 56.
The connections for the drive cylinders 36 and ~0 and the ~4 ~"`, check valves, only one of which (95) is shown in Fig. 6, are located in the check valve block 53 mounted on the control valve block 51.
According to Fig. 5, the control lever 18 passes through a shaft journal 58 supported in the ball bearing 54.
A gear drive block 60 is inserted in a recess 59 of the bearing block 50. The gear drive block 60 has a first ball bearing 61 for an additional shaft journal 62 and a second ball bearing 63 for a bevel gear 66.

In order to illustrate the eccentric arrangement of the follower pin 72, the shaft journal 62 is shown in Fig. 5, turned by 90 around its axis of rotation. In the central position of the slide 55 shown in Fig. 5 the follower pin 72 ; would be at the same height as the axis of rotation of the shaft journal 62 and the eccentric arrangement could not be detected.

The follower pin 72 also extends through the one end of the push rod 57~ The latter ex-tends into a bore 74 in the linkage block 52 up to a coupling piece 75 -that connects the push rod 57 with the piston rod 56. The bore 7~ is expanded in the lower zone and a guide sleeve 76 for the piston rod is inserted into the expanded portion of the bore 74.
An aligning bore 77 is present in the control valve block 51, coaxial to the bore 74 in the linkage block 52. The lower end of the bore 77 is closed off by a screw plug 78. One of the valve sleeves 79 is inserted in a stationary manner in the middle region of the bore 77. The valve sleeve 79 has the longitudinal bore 80, in which the valve slide 55 connected with the piston rod 56 is slidably supported.
Three grooves 81, 82 and 83 ~hat extend along the periphery and are connected through radial bores 8~ with the longitudinal bore 80 are also present in the surface of -the valve ~ushing 79. Two channels 85 and 86 empty into the groove 81, of which only channel 85 is visible in Fig. 6.
Two channels 87 and 88 empty into the groove 83, of which only channel 87 is visible in Fig. 6. A feed channel 89, which is visible only in Fig. 6 and is connected to the pipeline 31, empties into the middle groove 82. The upper end of the longitudinal bore 80 is connected with a drainage channel 90 and the lower end of the longitudinal bore is connected with a drainage channel 91. The two drainage 30 channels 90 and 91 are connected to the re-turn line 38. The valve slide 55 had two peripheral ribs 92 that contribute to delimiting an annular space 93. In the middle position, in which the valve slide 55 is shown in Figs. 5 and 6, the annular space 93 is connected only through -the middle groove -- Ç --;, 2`, t;~a~
77 with the feed channel 89. If the valve glide 55 is brought into its lower position by ac-tuating the control lever 18, pressure oil passes from the annular space g3 in-to the channels 87 and 88, which were previously connected with the drain channel 91. Pressure oil passes through the channel 87 into a channel 94 in the check valve block 53 to a check valve 95 and through the pipeline 41 to the drive cylinder 40 (see Fig. 2). The excess oil flows ~rom the drive cylinder 40 through the pipeline 42 and the positively opened check valve 96 into a channel (not shown) in the check valve block 53 and from there into the channel 86 and through the assigned radial bore 84 into the drain channel 90 and then, as indicated above, back to the reservoir 21.
If the valve slide 55 is brought into its upper position, pressure oil passes from the annular space 93 into the channels 85 and 86. The pressure oil flows from the channel 86 through a channel (which is not shown, but corresponds to the channel 94 in the check valve block 53) through the check valve 96 and the pipeline 42 to the drive cylinder 40 tsee Fig. 2).
The excess oil flows from the drive cylinder 40 through the pipeline ~1 into the check valve 95, which is positively opened in the manner described in the following, the channels 94 and 87 into the drain channel 91 and from there back into the reservoir 21.
The positive opening of the check valve 95 takes place through a piston 97 with a pin 98. The piston 97 is held by a pressure spring 99 in its rest position shown in Fig. 6. When the valve slide 55 is moved upward, pressure oil also passes into the channel 85 and through a narrow channel 100 in the check valve block 53 into the working chamber on the left-hand side of the piston 97, with respect to Fig. 6. This causes the piston 97 with the pin 98 to be shifted to the right. The free end of the pin 98 strikes ,, . .,~
the moveable valve body 101 of the check valve 95, which causes it to be positively opened against the return force of a valve spring 102. The check valve 96 is positively opened in an analogous manner if the valve slide 55 is moved downward. The axial passage through the guide sleeve 76 is reduced twice and contains a supporting shoulder 103 on which a support plate 104 for a pressure spring 105 lies if the valve slide 55 is in the middle position. The other end of the pressure spring 105 rests on a support plate 105, which lies against the upper face of the valve sleeve 79 iE
the valvs slide 55 is not in the upper position. Openings 107 are provided in the support plate 106 so that oil can ~low out of the channels 85 and ~6 into the drain channel 90, even if the support plate 106 lies against the valve sleeve 79. The pressure spring 105 assures that the piston rod 56 and -the valve slide 55 are in the middle position shown in Figs. 5 and 6 if no external force acts on the control lever 18 and the electric motor 68 is not energized.
For example, if the control lever 18 is swung backward into the drawing plane of the Figure, the follower pin 72 is moved upward. This upward movement is transfered from the follower pin 72 to the push rod 57, the piston rod 56 and the valve slide 55. The upward movement of the valve slide 55 also causes the support plate 106 to be moved upward against the returning force of the pressure spring 105. The pressure spring 105 is thus still further pretensioned so that it moves the valve slide 55 and the control lever 18 back into the middle position iE an external force no longer acts on the control lever 18.
If the con-trol leYer 18 is actuated in the opposite direction, the ~ollower pin 72 moves downward.
This downward movement is transfered to the push rod 57, the piston rod 56 and the valve slide 55. The piston rod 56 has a support shoulder 108 on which the support plate 10~ lies ~2~22~
during the downward rnovement and is also shifted downwardO
The pressure spring 105 is thus pretensioned because the support plate 106 lies against the face of the valve sleeve 79. If an external force no longer acts on the control lever 18, the pressure spring 105 assures the return of the contro] lever 13 and the valve slide 55 to the middle position.
Movements analogous to the upward and downward movements described above are also effected if the electric motor 68 is energi~ed so that it generates a torque in one direction or another.
The valve slide 5~ and thus the drive cylinder collaborating with it can be controlled without additional measures at any time by actuating either the control lever 18 or the remote control device.
In order -to prevent the electric motor 44 from becoming overheated during more prologned energization and to save energy, a limit switch 68 is provided. The limit switch 68 acts with an axial projection 132 on the face of the shaft journal 62 adjacent to the bevel gear 64. The projection 132 extends over an angle of ca. 60 and is designed so that if the valve slide 55 is in the middle position the trip stop 133 of the limit switch 68 lies in the middle of the axial projection 132. As long as the trip stop 133 lies on the projection 132, the limit switch 68 is closed. A resistance 134 is switched parallel to the limit switch 68 and it is switched in series to the electric motor 44 (see Fi~. 2). After a rotation of ca. 30 in the shaft journal 62 in one direction or another, the trip stop 133 slips off the projection 132 and the limit switch 68 opens.
As a result, the series-switching of the resistance 134 to the electric motor 44 becomes active. The current through the electric motor 44 is reduced by the resistance 134 so sharply that the residual torque is precisely sufficient to f ,~
3~ Z~
counteract the restoring force of the pressure spring 105.
In this manner, the valve slide 55 remains in its upper or lower position as long as the electric motor 4'1 remains energized.
5It is evident from Fig. 2 that it is still necessary to actuate the foot switch 'l9 in addition to actuating the control lever 18 or 15 in order to control the drive cylinder 36 and 40. The stand-by valve 29 is thus opened and the pressure oil can pass from the pressure oil 10accumulator 23 into the Eeed channel 89 in the control valve block 51. The stand-by valve 29 is shown in cross section in Fig. 7. It is comprised of a stationary valve body 109 with a valve seat 110, a moveable valve body 111 and a valve spring 112 that presses the moveable valve body 111 against 15the valve seat 110. The pipeline coming from the pressure oil accumulator 23 is connected to a connection 114 provided with threads 113. Pressure oil passes through an outlet channel 115 to the control panel 14 when the stand-by valve 29 is opened. The foot switch 49 is fastened to a bolt 116 20that extends through a guide sleeve 117. The inner end of the bolt 116 acts on one arm of a two-armed lever 118 that is pivotable around an axis 119. A setscrew 120 is screwed into the arm on which the bolt 116 acts directly and it can actuate the said valve body through a projection 121 25operatively connected with the moveable valve body 111 to open the stand-by valve 29. A roller 122 is suppor-ted on a shaft 123 on the other arm of the lever 118. A ball bearing 126, in which a cup-shaped swash plate 127 is supported (Fig. 8), is located in a recess 12~ o:f the housing block 30136 of the stand-by valve 29. The roller 122 rolls on t he edge of the swash plate 127. If the swash plate 127 turns in one direction or another, the lever 119 is swung counterclockwise with respect to Fig. 7 and the moveable valve body 111 is lifted from its valve seat 110. The ~ ,;

electric motor 48 is also placed in the said recess 124 and fixed with the aid o~ a setscrew 128. The drive shaft 129 of the electric motor 48 is connected with the swash plate 127 in a rotationally solid manner. A trip stop 130 o~ a limit switch 131 projects into the movement path of the lever 118.
As is evident from Fig. 2, a resistance is switched in series to the electric motor 48. The limit switch 131 is switched parallel to the resistance 135. The 10 limit switch 131 is designed so that the lever 118 presses the trip stop 130 into the limit switch 131 and thus opens the latter i~ the lever 118 is swung coun-terclockwise with respect to Fig. 7 and has displaced the projection 121 downward to open the stand-by valve 29. Analogously, as also described above with reference to the resistance 134 assigned to the electric motor 44, -the resistance 135 is dimensioned so that the reduced current flowing through the electric motor 48 still generates an ade~uate torque that prevents the lever 118 from returning prematurely to its rest position.
The stand-by valve 29 can be opened either by actuating the foot switch 49 or by energizing the electric motor 48, in which case the actuation of the foot switch 49 and energization of the electric motor can be effected 2~ directly, simultaneously and without causing damage.
The electric motors 43, 44 and 48 preferably have built-in geax drives with a gear ratio of 76 : 1, for example. The current necessary for driving the electric motors and delivered by the driver stage 47 can thus be further reduced.
The receiver 46 shown in Fig. 2 and driver stage 47 derive their power required for opera-tion from a rechargeable battery 136 that is located in a battery charger 137. The a.c. connections of the battery charger - . ,, .r'~
