Rebound spring and reset spring are installed on piston, the second sealing ring are equipped between the piston and body cavity, described
Piston is equipped with piston support ring, and pipeline of releasing is equipped in the bleeder valve, and plunger shaft exhaust pipe is equipped in the valve body
Road, the pipeline of releasing adjust the flow for pipeline of releasing by releasing speed adjustment screw through valve seat non-return valve core front end, from
And play the role of controlling speed of releasing, the plunger shaft gas exhaust piping is through solenoid valve to non-return valve core rear end.
Further improvement of the utility model is：Between the bolt and upper flange side, the bolt under
Third sealing ring is equipped between flange.
The utility model have the advantage that compared with prior art for：
1, compact-sized, robust performance is small in size, and flange is split type and is sealed using sealing ring, solve bolt it is fixed by
Gasket deformation influences, and the space of effective use increases flow area；
It 2, is load when solenoid valve vents behind solenoid valve vents pipe inner passage to valve before bleeder pipe inner passage to valve
When piston action be vented, after valve with communicated before valve, reduce leakage point, exhaust do not influenced.
3, after solenoid valve vents pipeline leads to valve, using the negative pressure of host suction chamber, intake valve is helped to open, improves and stablizes
Property, save the cost.
