Abstract:
A vehicular braking apparatus including a shut-off valve for shutting off, as needed, a flow of oil from a wheel cylinder to a master cylinder; a pressure increase-decrease control valve increasing and decreasing a pressure in the wheel cylinder; a reservoir receiving and storing in a reservoir chamber the oil from the wheel cylinder when the pressure increase-decrease control valve is in a pressure decrease position; a pump sucking in and pressuring the oil from the reservoir chamber and supplying the oil to the wheel cylinder via the pressure increase-decrease control valve when the pressure increase-decrease control valve is in a pressure increase position; and a communication control valve controlling communication between the master cylinder and the reservoir chamber. The communication control valve is a normally-closed valve and is opened by a suction pressure of the pump.
