Abstract
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.
