制御弁。First and second population chambers connected to pressure generation sources of different systems; first and second outlet chambers connected to brake application devices of different systems; and the first population chamber and the first exit chamber. a first valve provided in a passage communicating with the two and capable of blocking communication between the two, and a first valve movable against the biasing force from the spring device by effectively receiving pressure on at least the first outlet chamber side. A pressure regulating piston that opens and closes the pressure regulating piston, and a second pressure regulating piston that is provided in a passage that communicates the second population chamber and the second outlet chamber and is capable of blocking communication between the two.
a valve, which opens and closes the second valve to receive the pressure on the first outlet chamber side of the first valve and the pressure on the second outlet chamber side of the second valve so as to maintain both pressures in a predetermined relationship; and a deceleration responsive valve that closes at a predetermined deceleration, the deceleration responsive valve changing the biasing force of the spring device in response to control pressure introduced through the deceleration responsive valve. In the hydraulic control valve, the balancing mechanism includes a first movable body that receives pressure on the first outlet chamber side, a second movable body that receives pressure on the second outlet chamber side, and a structure between the two rotating bodies. a control chamber formed therein and into which the control pressure is introduced; and the first movable body and the piston are arranged in series.
