Embodiment
The present invention is described further below by specific embodiment:
See also Fig. 1, it is the take a breath structural representation of suction booster of the present invention.Described ventilation suction booster is made of support, cylinder body, two-position valve, piston assembly, specifically comprises support 13, right two-position valve 1, right stingy cylinder 2, right sealing gasket 3, right small piston 4, right small piston ring 5, right small piston connector 6, right piston rod 7, right large cylinder 8, right large piston connector 9, large piston 10, large piston ring 11, cylinder packing 12, left two-position valve 21, left stingy cylinder 19, left sealing gasket 20, left small piston 17, left small piston ring 18, left small piston connector 16, left piston connecting rod 15, left large cylinder 22, left large piston connector 14.
Wherein, left two-position valve 21, left sealing gasket 20 are bolted with left stingy cylinder 19, and left stingy cylinder 19 is bolted with left large cylinder 22.Left large cylinder 22, cylinder packing 12, right large cylinder 8 are bolted.Right large cylinder 8 is bolted with right stingy cylinder 2, and right stingy cylinder 2 is bolted with right two-position valve 1, makes two two-position valves and four cylinders form a housing assembly.
Cover has piston ring 18 on the left small piston 17, right small piston 4 covers have piston ring 5, large piston 10 covers have piston ring 11, large piston 10, left small piston 17, left large piston connector 14, left piston connecting rod 15, left small piston connector 16, right small piston 4, right large piston connector 9, right piston rod 7, right small piston connector 6 are bolted, such three pistons form a rigid body piston assembly, and be installed on housing assembly inside, and this housing assembly is placed on the support 13.
