Abstract
An actuating device for an entirely or partially hydraulic vehicle braking system includes a master brake cylinder with a piston and a working chamber hydraulically connectable to a reservoir, a pedal feel simulator, and, via at least one normally open valve, at least one brake circuit. At least one hydraulic wheel brake is assigned to a brake circuit and connected thereto via at least one separate controllable switching valve. A pressure supply unit has a motor-driven piston and a cylinder. At least one valve assembly includes wheel-specific solenoid pressure control valves. At least one electrical control unit controls valves of the valve assembly and the motor of the pressure supply unit. Outlet valves enable discharge of hydraulic medium from wheel brakes or brake circuits into the reservoir. One housing contains the valve assembly and hydraulic component of the pressure supply unit, and a separate housing contains the master brake cylinder.
