Abstract

An electrohydraulic unit having a hydraulic block with integrated valves, chambers, pumps and conduits, and electromagnets for the valves that are held on the hydraulic block. An electric motor for the pumps and relays for controlling the electromagnets and the electric motor. Electromagnets and relays are covered by a cover with connecting connectors for making an electrical contact. To make the design simple to manufacture and assemble, the cover is subdivided into a connector base and a covering hood that can be attached thereto. The connector base overlaps the electromagnets and the covering hood overlaps the relays, which are inserted into two connector receptacles disposed on the connector base and secured against axial displacement by the covering hood. The electrical connection of the electromagnets to the connectors and relays is effected via a flexible contact foil and a stamped screen embedded in the connector base.
