Abstract
A hydraulic pressure control valve for use with two independent rear braking systems, for transmitting braking hydraulic pressure to wheel cylinders in two rear wheels of a vehicle through two independent pipings. The control valve has a pair of valves, a pair of parallel pistons disposed in a single housing, and an actuating mechanism for displacing the pistons according to vehicle load. The actuating mechanism consists of a lever capable of rocking in a plane, a spring member for applying a force corresponding to the vehicle load to the rocking end of the lever, a support pin having both ends fitted in two grooves that extend parallel to the axes of the pistons and are equidistant from these axes, an equalizer which comes into abutment with one end of each piston at its either end. The equalizer is supported on the pin such that it can rock about its recessed center.
