Oil-in 33c, draining valve import 35a, pad oil-in 36a, oil suction valve block 34a is helped to flow
Enter the fuel supply chamber of oil cylinder 32.
Oil cylinder 32 relative to oil piston 31 to left movement time, the fuel supply chamber of oil cylinder 32 reduces,
Malleation is formed so that oil suction valve block 34a is close on pad oil-in 36a in this fuel supply chamber,
And oil extraction valve block 35b opens towards right side, then lubricating oil successively via oil sucting valve outlet 34b,
Pad oil-out 36b, oil extraction valve block 35b, oil-out 33b and flow in fuel feed pump 4, and
Via fuel feed pump 4, lubricating oil is delivered on motor body 2.Such as, Fig. 2 show by
Lubricating oil is delivered on the outer surface of housing 21 of motor body 2, to lower the temperature it.
In the above-described embodiments, owing to oil cylinder 32 is fixed on the outer surface of flange 13, and oily
Piston 31 is fixed on the internal face of shell 1, it is possible to ensure that oil cylinder 32 is relative to oil piston 31
Motion, reliable in action, thus ensure fuel feeding effect.It addition, in the above-described embodiments, oil cylinder
32 should try one's best with piston 12 relative to motor body 2 relative to the direction of motion of oil piston 31
The direction of motion keep consistent such that it is able to vibrate relatively produced by the motion because of piston 12
Pass to oil cylinder 32 to big degree, make oil cylinder 32 relatively big relative to the mobile degree of oil piston 31,
Be conducive to improving fuel delivery.
The foregoing is only presently preferred embodiments of the present invention, not in order to limit the present invention,
All within the spirit and principles in the present invention, any modification, equivalent substitution and improvement etc. made,
Should be included within the scope of the present invention.
Such as, in the above-described embodiment, oil cylinder 32 is fixed on the outer surface of flange 13,
But, the present invention is not limited to this, it is also possible to be fixed on other positions of motor body 1.
It addition, in the above-described embodiment, utilize screw sequentially pass through be opened in oil cylinder cover 33,
Installing hole on draining valve 35, pad 36, oil sucting valve 34 and oil cylinder 32 and by oil cylinder 32
It is fixed on the outer surface of flange 13.But it is not limited to this, also oil cylinder 32 directly can be welded
It is connected on the outer surface of flange 13.
It addition, in the above-described embodiment, by bolt 31b by connecting rod 31a of piston 31
It is fixed on the internal face of shell 1, but is not limited to this, also can be straight by connecting rod 31a
Connect on the internal face being welded in shell 1.
It addition, in the above-described embodiments, lubricating oil is delivered to the housing 21 of motor body 2
Outside wall surface on.But it is not limited to this, fuel feed pump 4 also can connect with compression chamber 18,
Thus lubricating oil is delivered in compression chamber 18, utilize this lubricating oil can be in compression chamber 18
Gas lower the temperature.Meanwhile, between the internal face and the outside wall surface of piston 12 of cylinder 11
Forming certain interval, fuel feed pump 4 also can connect with this gap, thus lubricating oil is delivered to this
In gap, advantageously reduce the friction between the internal face of cylinder 11 and the outer surface of piston 12
Power.
