Abstract
A fluid pressure control valve incorporated with dual hydraulic braking circuits connecting a tandem master cylinder to the left and right rear-wheel brake cylinders in a vehicle braking system. The control valve includes a pair of proportioning valves respectively disposed within the hydraulic braking circuits for modulating the hydraulic pressure applied to the rear-wheel brake cylinders, a pair of control plungers axially movable in response to fluid pressure in a hydraulic chamber to vary the spring load each acting on the proportioning valves, and a single inertia-controlled valve provided within an inlet pressure chamber of the control valve to interrupt the flow of fluid from one of the hydraulic braking circuits into the hydraulic chamber when a deceleration in excess of a predetermined value is attained.
