Beschreibung
Zusammenfassung:	A control valve for an automotive vehicle having a hydraulic power braking system comprising a valve body, a power piston to apply braking pressure force to the wheel cylinders, a pressurizing chamber in which is received the power cylinder, first valve means to control the braking pressure on the known skid sensing mechanism, and second valve means manually operable by the operator to control the application of the braking pressure from source means. A bypath passage is provided to reduce fluid pressure within the pressurizing chamber independently of the second valve means so that reduction of fluid pressure in the chamber is performed without any influence of varying lift of the second valve means upon or just prior to the locking of the brakes, uniformity of skid preventing operation resulting therefrom.
