[utility model content]
The purpose of this utility model solves the problems of the prior art exactly, a kind of short distance fuel-economizing air boosting pump is proposed, can reduce the disposable amount that adds braking liquid, can reduce in booster pump working process the long bubbles volume causing due to repairing path, thereby reduce the discharge vaporization of braking liquid.
For achieving the above object, the utility model proposes a kind of short distance fuel-economizing air boosting pump, comprise brake piston, thrust housing and filtering net, described thrust enclosure interior is provided with propelling rod, between described propelling rod and thrust housing, propelling rod seal ring is installed, thrust housing coordinates installation with braking housing, described braking enclosure interior is provided with brake piston, on described brake piston, piston packing ring is installed, on brake piston, be provided with brake piston oil inlet, the top of braking housing is provided with oil can, the inside of oil can is provided with filtering net, oil can coordinates installation with oil-can lid, on oil-can lid, be provided with scavenge port.
As preferably, described scavenge port is at the midway location of oil-can lid, and scavenge port is circular, and the diameter of scavenge port is 2～5mm.
As preferably, described propelling rod seal ring has two, is arranged on respectively the two ends of the face of propelling rod and thrust housing contact surface.
As preferably, between described oil can and braking housing, an oil can seal ring is installed, seal ring is arranged on the boss top on braking housing.
As preferably, described thrust enclosure interior is provided with pull back spring, and described pull back spring vertical section is trapezoidal.
The beneficial effects of the utility model: the utility model is by shortening the repairing path curve length of original product, can reduce the disposable amount that adds braking liquid, can be cost-saving, can also reduce in booster pump working process the long bubbles volume causing due to repairing path simultaneously, thereby reduce the discharge vaporization of braking liquid.
Feature of the present utility model and advantage will be elaborated by reference to the accompanying drawings by embodiment.
