1. A hydraulic unit for a slip-controlled brake system, comprising:
a block-shaped receiving body comprising a plurality of valve receiving holes for electromagnetically actuatable pressure control valves;
a through hole in the block-shaped receiving body for a pressure generator activated by electric motor, for which the through hole is aligned parallel to a direction of entry of the valve receiving holes into the block-shaped receiving body;
a master cylinder hole for receiving a master cylinder piston actuatable by means of a brake pedal, the master cylinder hole opening into the block-shaped receiving body transversely to the through hole and being connected to a pressure medium reservoir;
a simulator receiving hole for a brake pedal feel simulator, which within the simulator receiving hole has a simulator piston, which is acted upon hydraulically by the master cylinder piston, and a simulator spring, which counteracts the hydraulic pressure produced by the master cylinder piston; and
a plurality of pressure medium channels, which interlink the valve receiving holes, the pressure generator, the master cylinder hole and the simulator receiving hole, within the receiving body, into which there open a plurality of wheel brake connections, connectable via the pressure medium channels to a plurality of wheel brakes of the brake system,
wherein the simulator receiving hole is aligned transversely to the master cylinder hole in the receiving body; and
a pot shaped cover, wherein the simulator receiving hole is closed by the pot-shaped cover, wherein pot-shaped cover is directed into a cavity of a cap which covers the valve receiving holes, and that this cap integrates at least one of a plurality of electronic and electromechanical components wherein the pot-shaped cover comprises a rim cranked radially outward and is fixed in the region of the simulator receiving hole by means of plastic material deformation of the receiving body.
