Abstract (en)

[origin: WO2019011573A1] The invention relates to a hydraulic block for a slip control system of a hydraulic external force vehicle braking system which comprises a master brake cylinder bore (3) and forms a master brake cylinder (1). The invention proposes a hydraulic return flow damper (1 1) built into the master brake cylinder piston (5) to prevent a hard stop of a master brake cylinder piston (5) against an end stop when the master brake cylinder (1) is released, especially in the event of a sudden release, for example if the driver's foot slips from the brake pedal.
