ABSTRACT:
A hydraulic brake pressure control valve for an automotive vehicle which can provide an almost ideal ratio of front wheel cylinder hydraulic brake pressure to rear wheel cylinder hydraulic brake pressure, irrespective of vehicle weight and the increase rate of hydraulic brake pressure, in order to lock the front and rear wheels simultaneously. In control valve according to the present invention, a control plunger is moved up and down in response to the pressure difference between enclosed hydraulic brake pressure and the master cylinder hydraulic brake pressure; when the vehicle is unloaded, the enclosed brake pressure is sustained by a weak spring; when the vehicle is loaded, the enclosed brake pressure is sustained additionally by a strong spring.
