Abstract
An improved hydraulic braking pressure control device for a dual braking system including a pair of first and second hydraulic lines extending from a dual type brake master cylinder to the front and rear wheel brakes. The device includes a common housing mounted across the first and second hydraulic lines, and a pair of differential pistons slidably received in the aligned cylinder bores in the housing to respectively define on their opposite sides a first input and a first output hydraulic chamber and a second input and a second output hydraulic chamber, the adjacent input and output chambers being in communication with each other through respective valves which are operated to open and close by a pair of valve actuating pistons slidably fitted in the respective input chambers. A pressure control spring is arranged between the differential pistons to urge them in the direction away from each other. The valve actuating pistons are each operatively connected with the valves through a pair of connector assemblies with a predetermined amount of free displacement distance formed therebetween so as to allow free movements of the differential pistons within a definite range.
