Abstract: A rotating control system includes a member having at least one clevis defined by a pair of clevis arms disposed in a clevis plane, the at least one clevis having an axis of symmetry disposed in the clevis plane midway between the pair of clevis arms, a shaft member pivotally coupled between the pair of clevis arms, the shaft member having a shaft axis, the shaft axis disposed axially along the shaft member, and an anti-rotation device for limiting a rotation of the shaft member about the shaft axis, the anti-rotation device having a plurality of flanges configured to couple to the clevis arms of the member, the flanges extending from a surface of a base member, the anti-rotation device having at least one restraining member that protrudes toward the shaft member for limiting the axial rotation of the shaft member.

Abstract: 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.
