ABSTRACT:
A control valve assembly for a vehicle braking system comprises an inlet, an outlet, a proportioning valve having a control valve member movable to open and close the valve to control communication between the inlet and the outlet, and an inertia-responsive device, preferably a pendulum, responsive to deceleration of the vehicle and operable to reduce the pressure at the outlet after the valve has closed. The inertia-responsive device supplies a signal in dependence upon deceleration, and a servo system applies a force to the control valve member in response to the signal to move the control valve member in a direction to reduce the outlet pressure. The servo system comprises an auxiliary valve operable in response to movement of the inertia-responsive device, a pressure operable member subjected to a pressure in dependence upon operation of said auxiliary valve, and an arrangement coupling the pressure operable member in force-transmitting relation with the control valve member, whereby said control valve member is subjected to a force which is dependent upon the vehicle deceleration.
