Abstract
A hydraulic motor vehicle brake system having anti-skid system and further developed to improve vehicle tracking, especially during cornering by means of automatic braking. With automatic braking an auxiliary pressure source delivers a pressure medium to an anti-skid system, by means of which braking pressures can be individually adjusted in the wheel brakes. For this purpose a cylinder with separating piston sections is located between the auxiliary pressure source and the anti-skid system, wherein the separating piston is installed into 2/2-way valves including lip sealing rings. The embodiment in accordance with the invention include cylinders, with valve openings in cooperation with the lip sealing rings, which results in economical 2/2-way valves.
