Embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is done further to specify.
As shown in Figure 1, a kind of pneumatic fuel feeding oil cylinder comprises the cylinder block of being made up of cylinder baffle 1, cylinder protecgulum 2, cylinder back cover 3, piston 4, piston rod 5.One end of said piston rod 5 links to each other with piston 4, and the other end stretches out a side of cylinder block through cylinder back cover 3.Said cylinder protecgulum 2 is provided with filler opening 6, oil transportation mouth 7 and the oil spilling outlet 8 that communicates with said cylinder block inside, and the oil-feed opening of said filler opening 6 is positioned at the side of said cylinder protecgulum 2, and the cross section of said filler opening 6 is L-shaped.Said filler opening 6 is equipped with one-way control valve 13.The outlet opening of said oil transportation mouth 7 is positioned at the front-end face of said cylinder protecgulum 2, and said oil spilling outlet 8 is provided with unidirectional relief valve 18.The side end that said cylinder block is positioned at said cylinder back cover 3 is equipped with solenoid valve base 16, and solenoid valve 9 is installed on the solenoid valve base 16, and said solenoid valve 9 is the contact-type solenoid valve.The side end that said piston rod 5 stretches out said cylinder block is provided with the induction pressure cap 10 corresponding with said solenoid valve 9, and said cylinder back cover 3 is provided with suction port 11.Said cylinder protecgulum 2, cylinder back cover 3 and said cylinder baffle 1 are through bolt together.Between said cylinder protecgulum 2 and the said cylinder baffle 1, be equipped with O-ring seals 12 between said cylinder back cover 3 and the said cylinder baffle 1.Said piston 4 and said piston rod 5 joints be provided be used for fixing both from jack panel 14 and plain cushion 15.The position that contacts with said piston rod 5 on the said cylinder back cover 3 is provided with dust ring 17.
