Abstract
The utility model discloses an automobile clutch assistant slave-cylinder exhaust plant, which comprises a boosting cylinder, wherein the boosting cylinder is provided with a control valve, the control valve is provided with an exhaust filter cap, and the exhaust filter cap is provided with a one-way ventilation device. The exhaust filter cap adopts the one-way ventilation structure, can only exhaust but not suck air, so the utility model effectively solves the problem that under the condition of severe environment, water, dust and the like can enter a servo boosting air chamber along with the outer air, so that the servo chamber, and the servo boosting piston and other parts rust to fail the performance to be scrapped. The utility model has long service life and good sealing effect.
Description
Technical field
The present invention relates to the venting gas appliance of the clutch power-assisted wheel cylinder of a kind of automatic clutch system.
Background technique
Clutch power-assisted wheel cylinder is to be connected in the automobile hydraulic clutch pipeline, plays the parts of power-assisted effect during clutch.The clutch power-assisted wheel cylinder that exists comprises servo-cylinder, servo-cylinder piston, control valve, smoke releasing cap etc. at present.Smoke releasing cap plays simple filtration, two-way admittance.Because clutch power-assisted wheel cylinder is when just beginning clutch, servo-cylinder piston drive power-assisted servopiston moves to clutch power-assisted output push rod direction under hydraulic pressure, and the intake valve port of control valve is not opened as yet, and whole power-assisted chamber is in negative pressure, and ambient air enters the power-assisted chamber through smoke releasing cap.When severe environmental conditions, meetings such as water, dust enter the servo air chamber of power-assisted with ambient air, cause that parts such as servo air chamber, servo-assisted piston get rusty, and then inefficacy is scrapped.
Summary of the invention
Technical problem to be solved by this invention provides a kind of long service life, the automatic clutch power-assisted wheel cylinder venting gas appliance of good sealing effect.
For solving the problems of the technologies described above, technological scheme of the present invention is: automatic clutch power-assisted wheel cylinder venting gas appliance, comprise servo-cylinder, and on the described servo-cylinder control valve is installed, the exhaust gas filter cap is installed on the described control valve, and described exhaust gas filter cap is provided with unidirectional air-breather.
As optimized technical scheme, described unidirectional air-breather comprises and is installed in the valve plug that is arranged on the outlet of described exhaust gas filter cap, is provided with holddown spring between described valve plug and the described exhaust gas filter cap.
Owing to adopted technique scheme, automatic clutch power-assisted wheel cylinder venting gas appliance comprises servo-cylinder, on the described servo-cylinder control valve is installed, and the exhaust gas filter cap is installed on the described control valve, and described exhaust gas filter cap is provided with unidirectional air-breather.Adopted unidirectional ventilation device on the exhaust gas filter cap, can only exhaust, can not air inlet, solved effectively when severe environmental conditions, meetings such as water, dust enter servo-assisted air chamber with ambient air, cause that parts such as servo air chamber, servo-assisted piston get rusty, and then the problem that lost efficacy and scrap.The utlity model has long service life, advantage of good sealing effect.
