air chamber

354 and 355 etc.;

Driving mechanism 400 is made up of parts such as eccentric drive shaft 410, the axle collar 420 and pistons 430,431, and wherein eccentric drive shaft 410 is provided with an eccentric cam 411; Then be provided with several through holes 421,422 and 423 on the axle collar 420; Piston 430 and 431 is provided with the groove 432,433 and the fixing through hole 434,435 and the screw 436,437 used at the lucky nested axle collar 420 two ends 424,425; Retaining ring 440 is provided with two protruding seats 441,442 that stretch upwards, and is equipped with through hole 443,444 on the protruding seat 441,442, and the retaining ring center also is provided with a shrinkage pool 445;

Pipeline 600 is three-way pipes 601,602,603, and its inside is provided with a ball valve 604.

The compound mode of above-mentioned each part is as described below:

See also Fig. 2, be fixed on the valve face 107 of body 100 along 316,317,318,327,328,329,343,344,345,351,352,353 embeddings of the through hole on steel disc 310, dividing plate 320, liner 340 and the piece plate 350 respectively with screw; Earlier the cylinder block 101,102 of piston 430,431 along body 100 embedded, again that the two ends 424,425 of the axle collar 420 are sheathed along the groove 432,433 of piston 430,431, the fixing through hole 422,423 of the axle collar 420 simultaneously when making the lucky through hole 434,435 of pin 504,505 on piston 430,431 can being penetrated, live axle 410 is inserted along the axle collar 420 again, makes its eccentric cam 411 be located on the through hole 412 just; Again retaining ring 440 is embedded live axle 410 belows and be locked in respectively on the screw 436,437 of piston 430,431 belows, prevent that live axle 410 from coming off with screw.200 of top covers embed on the end face that covers the space 108 of being fixed in body 100 along live axle 410.Siphunculus 601, the 602 difference build-ins of pipeline 600 2 ends are in relief opening 105,106 places of body 100.
