摘要

In a braking system having a brake force booster (1), for motor vehicles whose wheels are each associated with a wheel brake cylinder connected by way of a brake line (6, 7) to a multi-circuit master cylinder (2), a valve arrangement (40) is connected to a pressure medium source (3) and permits pressure medium flow in the event of drive slip regulation into an adjusting chamber (23) of variable volume, to cause a piston of the master cylinder (2) to move in such a way that pressure build-up can be obtained at the wheel brake cylinder associated with a driven wheel. The system includes a control unit (13, 14) which is associated with at least one of the wheels and is disposed in the brake line (6, 7) such that, in the event of drive slip regulation, it can take up switching positions for pressure build-up and pressure reduction at the wheel brakes. The adjusting chamber (23) is defined by a rear face (25) of the piston (29) of the master cylinder (1) which faces the brake force booster (1) and an end face of a cylinder sleeve 33. By this arrangement no reaction force is transmitted to the brake pedal during anti drive slip operation. <IMAGE>
