Zusammenfassung:	A power steering pump for an automotive vehicle comprises a can housing that defines a compartment for receiving a cam plate and a pressure plate. The compartment is sealed by a cover that is threaded into an open end of the canister housing. The cover includes an annular contact that engages the pressure plate to urge the pressure plate against the cam plate. This produces a tight fit that reduces vibration and noise during pump operation. The cover also includes a central recess within the annular pressure plate contact that cooperates with the adjacent pressure plate to form a hydraulic fluid sump.
