ABSTRACT:
A brake control valve for an automobile includes a main body having first and second bores intersecting with each other; a ball valve member arranged in the first bore, and rolled by its weight when the automobile is facing upwardly on an inclined road-way; a valve seat arranged in the first bore, and engageable with the ball valve member to check brake fluid flow between a master cylinder and a wheel cylinder; and a cam shaft slidably fitted into the second bore and inter-connected to a clutch pedal, having a cam portion in a brake fluid passage. Areas of the cam shaft at both sides of the cam portion receiving fluid pressure are substantially equal to each other. The cam shaft is rotated round its axis with actuation of the clutch pedal to displace the ball valve member through the cam portion for opening and closing the valve seat when the automobile is facing upwardly on the inclined roadway.
