A slip-controlled brake system for automotive vehicles comprises a brake booster (1) acting on a tandem master cylinder (7, 7'), of pressure medium lines connecting the tandem master cylinder (7, 7') with the wheel brakes, as well as of controllable multi-directional valves (30, 31, 32, 37, 41, 50, 51, 53) in the pressure medium lines. The tandem master cylinder is composed of a push-rod piston (6, 42) of an intermediate piston (8), as well as of a resetting arrangement (23, 44). Further, an auxiliary pressure source (26), transducers for detecting the rotational behavior of the wheels, and electronic circuits for the evaluation of the measured values and for the generation of valve control signals are included in the brake system. The intermediate piston brake circuit (II) of the brake system is designed as a brake circuit which is static in all operational conditions and the push-rod piston brake circuit (I) is designed as a brake circuit which, in case of control, is dynamic and connectable to a pressure compensation reservoir (13) and to the auxiliary pressure source (26 ) via multi-directional valves (31, 32). The auxiliary pressure source (26) further communicates with the pressure compensation reservoir (13) by way of a valve (30) and with the resetting arrangement in a directly or by valves. |
