ABSTRACT:
A brake slip control apparatus fed with auxiliary energy for use in a vehicular hydraulic brake system, comprising a master-cylinder assembly (12) actuatable by the brake pedal, and with auxiliary energy being supplied into the working chamber (16) of the master cylinder. A resetting piston (49) is arranged axially slidably between stops on the secondary side of the master cylinder piston (23), which piston (49) causes the master cylinder piston (23) to assume a defined position in the event of application with auxiliary energy. To this end, the resetting piston (49) is slidably supported in an annular chamber (47) and, on brake actuation after having overcome a clearance (X), is entrained by the booster piston (57) in the actuating direction. Terminating into the annular chamber (49) is a throttle bore (46) through which pressure fluid out of the annular compartment (36) may enter into the annular chamber (47) in order to urge the resetting piston (49) back to its initial position.
