ABSTRACT:
The invention is directed to a pressure control apparatus in a vehicle braking system which has a wheel cylinder operatively mounted on a wheel, a reservoir for storing an amount of brake fluid, and a master cylinder for receiving the brake fluid from the reservoir and generating a master cylinder pressure in response to depression of a brake pedal. The pressure control apparatus includes a housing which defines therein a pressure chamber which communicates with the wheel cylinder, and a control device which is actuated by a current fed thereto for providing a set pressure in response to the current and regulating the pressure in the pressure chamber into the set pressure. The apparatus further includes a valve device, by which the pressure in the pressure chamber is increased when the master cylinder pressure is higher than the pressure in the pressure chamber, or when the set pressure is higher than the pressure in the pressure chamber, while the pressure in the pressure chamber is decreased when the master cylinder pressure is lower than the pressure in the pressure chamber, or when the set pressure is lower than the pressure in the pressure chamber.
