A power steering pump for an automotive vehicle including a housing defining a compartment, a cam plate disposed within the housing, a rotor disposed within the housing and a lower pressure plate disposed within the housing between the cam plate and a closed end of the housing. A cover sealingly engages the housing to close an open end of the housing. The cover includes under vane porting to provide a fluid path from an outlet port on the cover to the rotor.

Power steering pump

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.

A power steering pump for an automotive vehicle includes a housing having an inner wall with an axial groove. A cam plate that defines a cam chamber is received in the housing and includes a rib received in the groove. The groove and rib are disposed near the outlet port of the cam chamber and are dimensioned such that, during operation, distortion of the cam plate directs the rib into locking engagement with the groove while maintaining clearance between the housing and remainder of the cam plate to reduce propagation of vibration and noise.
