  • Brake fluid pressure control apparatus in skid control system
    Patent number: 4844558
    Abstract: A brake fluid pressure control apparatus in a skid control sytstem for a vehicle includes an electromagnetic change-over valve arranged in a conduct between a master and a wheel cylinder for the wheel. The electromagnetic change-over valve receives control signals of a control unit measuring the skid condition of the wheel to control the fluid pressure to the wheel cylinder. A hydraulic reservoir which, when the brake fluid pressure to the wheel cylinder is decreased with control of the electromagnetic change-over valve, reserves the brake fluid discharged through the electromagnetic change-over valve from the wheel cylinder and a fluid pressure pump supplies the brake fluid from the hydraulic reservoir into the wheel cylinder. A two-position electromagnetic change-over valve enables a change-over into a cut-off state or a communicating state. The valve is a conduit between the hydraulic reservoir and the fluid pressure pump.
