ABSTRACT:
A hydraulic brake system with slip control for automotive vehicles, comprising a master cylinder (2) pressurizable by a hydraulic power booster (1). The brake system further comprising valve elements (28, 29, 33, 36, 37, 38) which are disposed between the master cylinder (2) and the wheel brakes (30, 31, 34, 35), through which valves pressure fluid can be removed from the wheel brakes (30, 31, 34, 35) and replenished out of the pressure chamber (10) of the hydraulic power booster (1) through a change-over valve (26, 27, 42) controllable by a slip-monitoring arrangement (40). During a braking action after the first response of the slip-monitoring arrangement, further actions of pressure decrease and pressure increase in the wheel brakes are controllable by way of the pressure chamber (10) of the hydraulic power booster. During braking after response of the slip-monitoring arrangement (40), the change-over valve (26, 27, 42) with its inlet side is connectible in a self-holding fashion to the pressure chamber (10). Further, valves (26, 27) are arranged between the working chambers (16, 20) of the master cylinder (2) and at least the valve elements (30, 31), which valves after change-over of the first change-over valve (42) are connectible with their inlet side to the pressure chamber (10) by way of the first change-over valve (42).
