Abstract
An electrohydraulic braking system for motor vehicles with a brake master cylinder which can be actuated by a brake pedal. A wheel brake is coupled with at least with one vehicle wheel. The wheel brake can be connected with the brake master cylinder in order to subject the wheel brake to pressurized hydraulic fluid. A hydraulic pump, and a hydraulic pressure accumulator supplied by the pump, form an alternative source of pressurized hydraulic fluid which can be supplied to the wheel brake through a control valve arrangement in a controlled manner in order to subject the wheel brake to pressurized hydraulic fluid. A shut-off valve is arranged between the hydraulic pump and the hydraulic pressure accumulator in order to selectively make or shut-off a connection between the hydraulic pump and the hydraulic pressure accumulator to permit the hydraulic pump, in certain situations, to rapidly pressurize the braking system without having to simultaneously recharge the hydraulic pressure accumulator.
