摘要： The present invention starts from a vehicle hydraulic brake system comprising a master cylinder (2) actuatable by a hydraulic power booster (1) and containing a working chamber (12, 21), to which latter wheel brakes (36, 37, 38, 39) are connected by way of valves (40, 41) controllable by a slip control electronics. On control action, pressure fluid can be taken from the wheel brakes (36, 37, 38, 39) through the valves (40, 41) and can be replenished out of the presser chamber (5) of the hydraulic power booster (1) by way of the working chamber of the hydraulic power booster by way of the working chamber (12, 21). On communication of the working chamber (12, 21) with the pressure chamber (5) of the hydraulic power booster (1), simultaneously, a resetting sleeve (11) is pressurized in the brake's release direction which is penetrated by a master cylinder piston (10) and which serves to limit the stroke of the brake pedal (6). In particular with a view to simplifying the design of the braking pressure generator (1, 2), it is proposed that an annular housing chamber (15), which is confined by the end face of the resetting sleeve (11) that is remote from the working chamber (12), is normally isolated from an unpressurized supply reservoir (18) and is in communication to said supply reservoir (18) exclusively during brake slip control.

摘要： A vacuum brake force booster is provided wherein the pressure column above the immersing valve plunger of the dual valve contained in the piston chamber, in the applied position, generates a reaction force imparting to the vehicle drive the feeling of the extent of deacceleration. In addition to the valve plunger coupled to the push rod of the brake pedal, the control housing in the piston chamber is displaceable in the brake housing along with the movable wall and acts as a plunger piston. For this purpose, the control housing is sealingly passed through a wall of the master cylinder. The intermediate piston separating the two piston chambers in the master cylinder at the front side thereof facing the valve piston is provided with a rubber reaction disc. The valve plunger and the control housing or a sleeve cooperating with the control housing, in the event of a failure of one of the brake circuits, will abut the reaction disc.
