Efferent duct 304, wherein the input terminal of one first check valve 310 connect connection, output end and a left side with the output end of left efferent duct 304
The connection of gas chamber 206 is connected, and right exhaust valve is provided with and communicated with right efferent duct 305, the input pipe of another first check valve 310 and the right side
The output end of efferent duct 305 connects connection, output end and connect connection with right gas chamber 207, can in order to control intake valve
It is connected with left exhaust valve/right exhaust valve, the inlet chamber 302 is internally provided with matched air inlet spool 306, air inlet
Spool 306 includes connecting rod 306b and is coaxially fixedly installed on the core 306a of connecting rod 306b end position, core 306a with into
Air cavity 302 constitutes the cooperation of sealed slide-and-guide, core 306a for being blocked to exhaust valve, core 306a slide into
302 left end of air cavity is for blocking right exhaust valve, core 306a slides into 302 right end of inlet chamber for left exhaust gas
Door is blocked.
Specifically, first check valve 310 includes the check valve body 311 for being internally provided with cylindrical inner chamber, check valve
The output end of body 311 is coaxially arranged with annular convex platform 312, and the output end of check valve body 311 and the right gas chamber 207 of left gas chamber 206/ connect
It connects, right 305 output end of efferent duct of left efferent duct 304/ is inserted into the input terminal of check valve body 311 and interfaced connects
It is logical, the cylinder 313 that sealed slide-and-guide cooperation is constituted with it is coaxially arranged in check valve body 311, cylinder 313 can be unidirectional
Slided between the input terminal and boss 312 of valve body 311, cylinder 313 close to boss 312 it is open at one end arrangement, deviate from boss 312 1
End seal closes arrangement, and reset spring 314 is movably set in check valve body 311, and 314 one end of reset spring and boss 312 contradict, are another
One end and the closed end of cylinder 313 contradict and the elastic force of reset spring 314 is directed toward cylinder 313 by boss 312 always, in order to
Enough make to be connected inside check valve body 311, annular docking groove 315, annular docking are coaxially offered in 311 inner cavity of check valve body
Slot 315 be located at check valve body 311 offered along the medium position of its conveying direction, the periphery of the cylinder 313 in it
The through-hole 316 and through-hole 316 that portion connects arrange that through-hole 316 is provided with multiple and along cylinder close to the closed end of cylinder 313
313 place circumferencial direction arrays arrangement, the distance between original state lower shell 313 and boss 312 are equal to through-hole 316 and annular
The distance between docking groove 315, high pressure gas by overcome reset spring 314 elastic force act on push cylinder 313 slide into
Boss 312 fits, and so that through-hole 316 is aligned with annular docking groove 315, to make to be connected inside check valve body 311.
During the work time, when core 306a moves to 302 right end of inlet chamber, core 306a is to a left side for admission gear 300
Exhaust valve is blocked, and intake valve connect connection with right exhaust valve, and high pressure gas will enter right output by inlet chamber 302
Pipe 305 unidirectionally flows into right gas chamber 207 by the first check valve 310, and piston 203 is moved downward up to moving to terminal, this
When, the left end that exhaust gear 400 will make core 306a slide into inlet chamber 302, core 306a blocks right exhaust valve,
Intake valve connect connection with left exhaust valve, and high pressure gas will enter left efferent duct 304 by inlet chamber 302, single by first
It is unidirectionally flowed into left gas chamber 206 to valve 310, piston 203 moves right until moving to terminal, at this point, exhaust gear 400 will
So that core 306a is slid into the right end of inlet chamber 302, and so on carry out, makes intake valve alternately to left gas chamber 206, right gas chamber
207 are supplied.
In order to which its internal gas is discharged by the right gas chamber 207 of extruded left gas chamber 206/ and triggers core
The sliding of 306a left/right, the exhaust gear 400 include exhaust valve 410 and commutation component 420, the input of exhaust valve 410
End is connected with the first check valve 310, and the input terminal of the first check valve 310 and exhaust valve 410 under on state disconnects, and disconnects
The first check valve 310 under state is connected with the input terminal of exhaust valve 410, and exhaust valve 410 is arranged to the open shape mutually switched
State is with closed state and original state is in an open state, and the exhaust valve 410 and commutation component 420 of closed state are connected, and is vented
The right gas chamber 207 of left gas chamber 206/ is compressed in Cheng Zhong, the sliding of 203 left/right of piston, and compressed gas will be by disconnection shape
The first check valve 310 under state is discharged outside in air, will be certainly when the terminal of 203 left/right movements of piston to stroke
Dynamic triggering makes exhaust valve 410 switch to closed state, and compressed air will be exported by exhaust valve 410 into commutation component 420,
Air pressure inside commutation component 420 is gradually increased and core 306a left/right is pushed to slide, and makes air inlet Vavle switching to left gas
The right gas chamber 207 in room 206/ is supplied, and the meaning of this programme is taken to be, is made compressed in the right gas chamber 207 of left gas chamber 206/
Gas discharges a part by exhaust valve 410 first, and then exhaust valve 410 is closed, and compressed gas enters back into commutation structure
The commutation distribution of 420 internal trigger intake valve of part avoids gas compressed in the right gas chamber 207 of left gas chamber 206/ from being all expelled to and changes
Cause to form high pressure reverse load inside it into component 420, can not be successfully the commutation distribution of triggering intake valve.
