Description
[technical field]
The utility model relates to the technical field of air boosting pump, particularly a kind of technical field of buffer air boosting pump.
[background technology]
Air boosting pump is requisite device in a lot of mechanical braking sytem; especially automotive field; its effect is by air-pressure controlling oil circuit supply; to realize the object of braking; prior art air boosting pump leak tightness is poor; in actual use; often there will be leakage of oil; major cause is that ring wear causes; due to booster pump work schedule hydrodynamic high pressure, when braking release, high-pressure brake liquid straight line shock sealing member; cause the quick broken invalid of sealing member, add the maintenance cost of machinery.
[utility model content]
The purpose of this utility model solves the problems of the prior art exactly; propose a kind of buffer air boosting pump, can make high-pressure brake liquid after buffer hoodle buffering, the instant impact of sealing member is reduced greatly; effectively protect sealing member, improve service life.
For achieving the above object, the utility model proposes a kind of buffer air boosting pump, comprise buffer hoodle, detent housing and thrust housing, described thrust enclosure interior is provided with propelling rod, described propelling rod coordinates with brake piston to be installed, the right side of described brake piston is provided with oil inlet and oil return chamber, inside, oil inlet and oil return chamber is provided with buffer hoodle, the exit in oil inlet and oil return chamber is provided with baffle ring, brake piston is arranged on the inside of detent housing, described detent housing is provided with oil can, and the inside of described oil can is provided with filtering net.
As preferably, described buffer hoodle inside is solid or hollow, and the thickness of buffer hoodle wall is 2 ~ 5mm.
As preferably, described thrust housing and detent housing bolt coordinate to be installed, and the quantity of bolt is 4.
As preferably, be that fine thread connects between described oil can and oil-can lid.
As preferably, be provided with sealing plug in described brake piston, described sealing plug is circular, and sealing is plugged with three grades of steps, has the groove that circular in the middle of sealing plug.
As preferably, a rectangular seal is installed between described propelling rod and detent housing, a circular seal ring is installed between propelling rod and detent housing.
The beneficial effects of the utility model: the utility model increases buffer hoodle by the oil inlet and oil return mouth at brake piston, decreases the impact of hydraulic oil to sealing plug in the course of the work, greatly can extend the life-span of sealing plug.
Feature of the present utility model and advantage will be described in detail by reference to the accompanying drawings by embodiment.
