Definitions
- the present invention relates to a combustion-powered setting tool in the preamble of Patent claim 1 mentioned type and a propellant container in the preamble of independent patent claim mentioned type.
- Such setting devices can by means of liquid or gaseous fuels are operated.
- DE 42 43 617 A1 discloses a combustion-powered setting tool, in which in a duty cycle, a gas inlet valve is mechanically opened, so that by a Propellant container fuel enters a storage space. From this storage space starting the fuel then passes before an ignition process in the combustion chamber.
- the Propellant container is designed as a liquid gas cartridge, the interchangeable in one Recording is arranged on setting tool.
- the object of the present invention is therefore to provide a setting device of the aforementioned To develop kind, which avoids the mentioned disadvantages.
- a detection device for detecting a propellant container in the Recording available the detected in the absence of the propellant container ignition blocked by propellant through the igniter and the detected presence of the Propellant container allows the ignition of propellant through the ignition device.
- the blockage of the ignition mechanism prevents it from unwanted ignition comes from possibly still in the setting device still existing propellant or fuel gas.
- the detection device includes a switching means that at detected absence of the propellant container in the recording an ignition circuit opens and that when detected presence of the propellant container in the recording the Ignition circuit closes.
- the interruption of the ignition mechanism or the ignition device is very fast and less susceptible to interference.
- the detection device includes a sensor. This allows the Presence or absence of a propellant container in a simple manner without contact and done safely.
- the sensor can be z. B. as a Hall sensor, capacitive sensor or Be formed light barrier sensor.
- the detection device includes a push-button switch, which is deflected or pressed by the propellant container when this is in the Recording is located. As a result, the detection device can be relatively inexpensive be designed.
- a propellant container such as a fuel pressure tank a Detection auxiliary, which is easily detected by the detection device.
- detection aid may, for. B. be designed as a permanent magnet, the at the use of a Hall sensor as a sensor of the detection device a good Detectability of the propellant container ensures.
- Figs. 1 to 3 is an inventive, with a liquid or gaseous Fuel operable as a blowing agent setting device 10 with a propellant container 20th played.
- the setting device 10 has a housing 11 with an integrally formed thereon Handle 16 on which a trigger switch 17 is located by means of a Setting process can be triggered.
- the setting device 10 also has a setting network 12, the one in a piston guide 14 and a cylinder displaceably guided drive piston 13 and a subsequent to the piston guide 14 combustion chamber 38 includes.
- the propellant container 20 is replaceable arranged, which is formed in the present embodiment as a pressure vessel.
- the propellant container 20 is connected via a fuel line 29 with a metering device 25 connected, the z.
- a first and a second valve means 26, 28 and one between them arranged chamber 27 has.
- the fuel line 29 is the metering device 25th then further connected to the combustion chamber 38, so that from the propellant container 20th via the fuel line 29 and the metering device 25, propellant or fuel in the Combustion chamber 38 of the setting device 10 can be output.
- an ignition device 18 is arranged, via which an air-blowing agent mixture located in the combustion chamber 38 is ignitable.
- a total of 30 designated detection device comprises a sensor 32, the in the present case is designed as a Hall sensor, and a switching means 31, such. B. one electronic switch, on.
- the sensor 32 is arranged on the receptacle 15 and partially protrudes into this.
- the switching means 31 may be part of the sensor or else also a separate part, as shown in Figures 1 and 2.
- the switching means 31 is in the Ignition circuit 19 interposed and can close or interrupt this.
- the designed as a pressure vessel propellant container 20 has a housing 21 in the interior 22 of the propellant in the form of a gaseous and / or liquid Fuel, such. B. LPG, is present.
- the reproduced in Figs. 1 to 3 Propellant container 20 has at its connection side to the fuel line 29 of the Setting device 10 a detection aid 24, which is designed as a permanent magnet is. This acts with the trained as a Hall sensor sensor 32 of the detection device 30 of the setting device 10 together.
- the detection aid 24 is in the Recipient 15 located propellant container 20 detected by the detection device 30, and the ignition circuit 19 as shown in Fig. 1 via the switching means 31 of Detection device 30 is closed, so that an ignition of the ignition device 18th can be triggered by the trigger switch 17 when the setting device 10 to a Substrate is pressed.
- Fig. 2 no propellant container is inserted into the receptacle 15 of the setting device 10 and connected to the fuel line 29. But it can still be propellant in the Fuel line 29 and in particular in the metering device 25 with the chamber 27th are located. From the sensor 32 is now detected but that no propellant container in the receptacle 15 is located, so that the switching means 31 interrupts the ignition circuit 19. Unintentional triggering of the setting device 10 is thus not possible.
- the setting device shown in detail in FIG. 4 differs only in this way from the above-described setting device that the detection device 30 instead of a Sensors and a switching means a push button 33 has the directly in the Ignition circuit 19 is integrated.
- the detection device 30 instead of a Sensors and a switching means a push button 33 has the directly in the Ignition circuit 19 is integrated.
- This key switch is purely mechanical the Presence of a propellant container 20 queried and the ignition circuit 19th interrupted when no propellant container 20 is in the receptacle 15.
- the further functional description of the setting device is fully related to the preceding description of FIGS. 1 to 3.
- the setting device shown in detail in FIG. 5 differs only in this way of the setting device illustrated in FIGS. 1 to 3, that the detection device 30 instead of a Hall sensor has a designed as a capacitive sensor sensor 32. This is connected to a switching means as already to the figures 1 to 3 has been described. If there is no propellant container 20 in the receptacle 15, then the capacitive field changes in front of the sensor 32. The detection device interrupts then via the switching means the ignition circuit, so that a triggering of the setting device not possible. Regarding the further functional description of the setting tool is fully incorporated by reference to the preceding description of FIGS. 1 to Third
