Hydraulic brake control assembly

摘要

A hydraulic brake control assembly is provided in which a proportioning valve is actuated to reduce fluid pressure to be supplied to rear cylinders from a master cylinder in accordance with the vehicle deceleration. An inertia ball is adapted to control the movement of the proportioning valve via a flexible disc valve to increase or reduce the fluid pressure supply to the rear cylinders. The disc valve is deformable to open the proportioning valve if the pressure of the master cylinder exceeds a predetermined level.
