Embodiment

Below in conjunction with drawings and Examples the utility model is further specified.

The pneumatic cylinder of the automatic reciprocating work of gas control of the present utility model, its structure is made up of pneumatic cylinder and air operated reversing valve, at the primary air inlet 11 of common air operated reversing valve body 20 and the cylinder type valve gap 5 at air operated reversing valve body 20 two ends, the auxiliary passage 9 of calming the anger is set between 21, at cylinder

type valve gap

5,21 the arranged outside interface 6 of giving vent to anger, 15, the interface 6 of giving vent to anger, 15 by tracheae respectively with the cylinder cap 3 that is arranged on pneumatic cylinder 16 two ends, piston head open type one-way valve 1 on 18,19 connect two piston head open type one-

way valves

1,19 top-opening type steam outlet pipe 22 extends in the pneumatic cylinder 16 and two planes of working piston 2 join.

Piston-cylinder top-opening type one-way valve the 1, the 19th is chewed 26 by stepped shape valve body 23, top-opening type steam outlet pipe 22, valve ball 25, spring 24 and air inlet and is formed, in the middle of the stepped shape valve body 23 is stepped cavity, top-opening type steam outlet pipe 22 is arranged on stepped shape valve body 23 left ends and internal step scalariform cavity left end is slidingly connected, top-opening type steam outlet pipe 22 right-hand members join with the valve ball 25 that is arranged on stepped shaft valve body 23 centres, air inlet is chewed 26 and is tightly connected by screw thread and stepped shaft valve body 23 right-hand members, and air inlet is chewed 26 and joined by spring 24 and valve ball 25 right sides in the ladder-type valve body 23.

Embodiment: the working principle of the pneumatic cylinder of the automatic reciprocating work of gas control of the present utility model is as follows:

Pulsometer is given primary air inlet 11 air feed by pipeline; High pressure draught is discharged from left main vent 27 by reversing valve core 29 and is entered pneumatic cylinder 16 piston 2 that pushes the work forward through left air inlet 17 and move to right; Working piston 2 rightward space are compressed; Be in exhaust condition; Gas enters atmosphere through pipeline, right main porting 28 and reversing valve core 29 from right emptying air nozzle by right cylinder cap air inlet/outlet 4; When working piston 2 moves on to right cylinder cap 3 front; Top-opening type escape pipe 22 indentations of roof pressure piston top open type check valve 1; Push valve ball 25 open and open exhaust

Because primary air inlet 11 equates by the pressure of auxiliary air inlet channel 9 for left spool driven plunger active chamber 14 and right spool driven plunger active chamber 7, the air pressure of left side spool driven plunger active chamber 14 reduces when roof pressure piston head open type one-way valve 1 is opened, the pressure of right spool driven plunger active chamber 17 is greater than left spool driven plunger active chamber 14, changeover valve core 29 is promoted left by right spool driven plunger 8, the pressurized gas of primary air inlet 11 are through changeover valve core 29, right main porting 28, tracheae 30 and right cylinder cap air inlet/outlet 4 air inlet cylinder pressures the right, the piston that pushes the work forward is moved to the left again, this moment, the space on pneumatic cylinder 16 left sides was in emptying state, and gas is by left cylinder cap air inlet/outlet 17, tracheae 30 and left main porting 27 are chewed 12 emptyings dropping a hint from a left side through changeover valve core 29.As long as source of the gas is arranged, working piston 2 will be always by the said process work that moves in circles.

Auxiliary air inlet channel can adopt the commutation valve body built-in, also can adopt external, connects by pipeline exactly.Piston head open type one-way valve is not limit and ball valve, also can adopt plunger one-way valve and other forms of one-way valve.
