The 7th through-hole that high pressure brake-fluid is equipped with by liquid outlet, bowl-shape skeleton, washes elastic sealing gasket open, passes through the 6th in bolt body
Through-hole enters braking clamp and forms braking；When brake piston toward it is return when, brake-fluid pressure reduction, but the pressure of brake-fluid at this time
Power is greater than the pretightning force of the 3rd spring, and bowl-shape skeleton is made to be detached from the contact of bolt body right side, brake-fluid by bowl-shape skeleton with
Gap between 2nd blind hole inner wall returns to brake chamber, when the pressure of brake-fluid in braking clamp and pipeline is pre- less than the 3rd spring
Clamp force, the 3rd spring again push back bowl-shape skeleton, and bowl-shape skeleton and bolt body right side are contacted again, and prevent from braking
Pincers and pipeline in brake-fluid continue to flow into brake chamber, thus part brake-fluid by residual voltage jam pot cover in pipeline and brake pump, under
Secondary braking keeps a part of pretightning force, and rapidly, safety is good for braking.
The present invention sets up liquid flowing valve between detent housing and fluid reservoir, and when releasing braking, brake piston is toward return
When, when left guiding axis encounters mandril lower end, mandril overcomes the stress of the 2nd spring, and mandril inclination makes position-arresting disk and the 3rd sealing ring
Gap is formed, fluid reservoir and brake chamber establish channel, and the brake-fluid in fluid reservoir adds in brake chamber；When braking, it brakes
Piston is toward moving left, and mandril is under the action of 2 spring, mandril return, and position-arresting disk is by space closure, and fluid reservoir and brake chamber are not
Resettle channel.Therefore, in brake process, the brake-fluid in fluid reservoir will not stir up and down, and brake-fluid is sealing, make to stop
The accessory of vehicle pump the inside will not be aoxidized because air is entered, to increase the service life of brake-fluid and brake pump.
To sum up, a kind of new brake pump brake of the present invention uses safe, and high reliablity, structure is simple, and production cost is low, no
It needs often to repair.
