Patent ID: 7780244

Claim:
A vehicle brake device comprising: a fluid pressure generating unit which generates fluid pressure in accordance with an operation amount; a wheel brake mounted on a road wheel; a normally opened control valve interposed between the fluid pressure generating unit and the wheel brake, and configured into a short-time rating valve, the normally opened control valve being electrically controlled in such a manner as to change over between a fully opened state, and a fully closed state, and also to obtain a half opened state between the fully opened and the fully closed states; a normally opened opening/closing valve which is interposed between the fluid pressure generating unit and the wheel brake, is electrically controlled to open and close a fluid passage between the fluid pressure generating unit and the wheel brake, and configured into long-time rating valve; and a pump adapted to pressurize the passage between the fluid pressure generating unit and the wheel brake while the communication between the fluid pressure generating unit and the wheel brake is isolated, a housing comprising a hydraulic modulator including: a reservoir; the normally opened control valve which is connected to the fluid pressure generating unit via the normally opened opening/closing valve; the pump having: a discharge side connected to a hydraulic line which is connected to the fluid pressure generating unit via the normally opened control valve and the normally opened opening/closing valve; and a suction side connected to the reservoir; a control valve unit which changeably makes and breaks communication between the hydraulic line of the wheel brake and the reservoir; and a normally closed opening/closing valve which is provided along a suction line between the normally opened control valve and the normally opened opening/closing to the suction side of the pump, wherein the normally opened opening/closing is connected to the normally opened control valve in series between the fluid pressure generating unit and the wheel brake, and wherein a suction port of the pump is connected to a position between the normally opened control valve and the normally opened opening/closing valve wherein the normally opened opening/closing valve is connected to the housing as an assembly which is separated from the housing.
