초록 ▼

A brake fluid pressure control apparatus in a skid control system for a vehicle includes a brake fluid pressure control valve device arranged between a master cylinder and wheel cylinders. The device receives control signals from a control unit that measures the skid condition of wheels. The device controls the brake fluid pressure to the wheel cylinders in response to the control signals. A hydraulic reservoir stores the fluid discharged through the device from the wheel cylinders when the pressure to the wheel cylinders is decreased under the control of the device. A fluid pump returns fluid from the reservoir into a pressure fluid supply conduit connecting the master cylinder and the device. A check valve arranged in the supply conduit opens when the fluid flows from the master cylinder towards the device, the outlet of the pump being connected to the conduit between the check valve and the device. A pressure fluid return conduit connects the master cylinder and the wheel cylinders. A check valve arranged in the return conduit opens when the fluid flows from the wheel cylinders towards the master cylinder. A fluid pressure adjusting valve receives fluid discharged from the pump.
