BLOCKIERGESCHUETZTE BREMSANLAGE

摘要

A hydraulic, antilock braking system has a pump (8) and a master cylinder (1). The valve for regulating the pump pressure is integrated in the master cylinder (1) and is composed of a combined seal (30, 34) that cooperates with a compensating bore (36). The seal (30, 34) is composed of an inner elastic ring (37) and an outer sliding ring (38). The communication required between the reservoir (7) and the brake circuits in order to fill up the brake circuits through a nonreturn valve is established through the nonreturn valves (10, 11) of the pump (9). A packing (41) may be added to the double seal (30, 34) in order to reliably seal the working chamber (39, 40) even when small leakage currents occur through the double seal (30, 34).
