ABSTRACT:
A control valve for use in an automotive brake system for controlling the brake fluid pressure in rear-wheel cylinders of the type include an inlet chamber communicated with a master cylinder, an outlet chamber in communication with the rear-wheel cylinders, a valve chamber in hydraulic communication with both of the inlet and outlet chambers, the latter being communicated through a valve port, a ball valve floatingly disposed within the valve chamber and actuable to close the valve port when the deceleration of an automotive vehicle reaches a predetermined level, and a differential piston with its free ends disposed in the inlet and outlet chambers, respectively, to be exerted with the brake fluid pressure therein. A variable restriction is disposed upstream or downstream of the valve chamber and is actuable in response to the flow rate of brake fluid flowing therethrough in such a manner that when the flow rate exceeds a predetermined value, the flow of brake fluid may be restricted, thereby eliminating the departure of braking force distribution from an idealized distribution when brakes are abruptly applied.
