CONTROL DEVICE FOR A FULLY OR PARTIALLY HYDRAULICALLY OPERATED BRAKING SYSTEM FOR A VEHICLE

The invention relates to an actuating device for a wholly or partially hydraulically effective braking system for a vehicle, with a master brake cylinder (HZ) having a piston-cylinder unit which has a piston and a working chamber, wherein the working chamber is hydraulically connected or connectable to a reservoir (VB) and a pedal feel simulator and is mechanically connected via an actuating device, in particular a brake pedal, and the working chamber is connectable via at least one de-energized open valve (FV) to at least one brake circuit (BK1, BK2), and that at least one hydraulically effective wheel brake (RB) assigned to a brake circuit (BK1, BK2), to which at least one respective controllable switching valve (SV) is assigned, with which the wheel brake (RB) is connectable to the respective brake circuit (BK1, BK2) for pressure build-up (pauf) and pressure reduction (pab), in particular in brake booster operation, wherein with a pressure supply (DV1) driven by an electric motor (2), whose piston is adjustable in the cylinder by means of the electric motor (2), and at least one valve arrangement (HCU) with solenoid valves for individual wheel pressure control, as well as at least one electrical control unit (ECU) for controlling at least valves of the valve arrangement (ECU) and the motor of the pressure supply (DV1), wherein at least one controlled outlet valve (AV), via which hydraulic medium can be directly discharged, in particular during control operation (ABS), from the respective wheel brake (RB) or the brake circuit (BK1, BK2) into the reservoir (VB), and wherein the valve arrangement (HCU) and the hydraulic portion of the pressure supply (DV) are arranged in a housing (A) and the master brake cylinder (HZ) is arranged in a separate housing (C).
