With piston A, the pump housing is equipped with plunger shaft A, and the piston A and plunger shaft A mutual cooperation is slidably connected, the piston A tool
There is the stress surface for pushing piston A mobile, which is characterized in that the pump housing is equipped with No.1 oilhole and No. two oilholes, described
No.1 oilhole and No. two oilholes are connected to plunger shaft A, and the stress surface is equipped with stress surface A and stress surface B, the stress surface A
Corresponding No.1 oilhole setting, the corresponding No. two oilholes setting of the stress surface B.
The piston A is the truncated conical shape with two-stage ladder, and the stress surface A is first order step surface, the stress
Face B is second level step surface.
Plunger shaft B is additionally provided on the pump housing, the plunger shaft A and plunger shaft B are symmetrically set, the plunger shaft B
It is interior it is corresponding be equipped with piston B, be additionally provided with No. three oilholes and No. four oilholes on the pump housing, No. three oilholes and No. four oilholes are equal
It is connected to plunger shaft B.
The beneficial effects of the utility model are: via hydraulic action caused by No.1 oilhole in the stress surface A of piston A
On, piston A can be pushed mobile, to realize braking；Via hydraulic action caused by No. two oilholes in the stress surface B of piston A
On, it can also push piston A mobile, to realize braking.
