Abstract
Through a valve arrangement for brake systems of automotive vehicles comprising an electronic antilocking and traction slip control including a two-circuit brake pressure generator (3) and an auxiliary pressure supply system (5) generating an auxiliary pressure proportional to the pedal force and, in traction slip control, generating an uncontrollable auxiliary pressure, either the brake pressure generator (1) or the auxiliary pressure supply system is capable of being connected to the wheel brakes (26-29). The non-driven wheel (HR, HL) of the vehicle is connected directly while the drive wheel (VR, VL) of the vehicle is connected, through an additional multi-way valve, to the brake pressure generator (1) and to the auxiliary pressure supply system (12). Moreover, the wheel brakes (27, 29) of the driven wheels (VR, VL), through additional multi-way valves (20, 21) for the traction slip control, can be directly connected to the auxiliary pressure supply system(5).
