A power steering pump for an automotive vehicle comprising:
- a housing defining a compartment, said housing further including an axis, a closed end and an open end;
- a cam plate disposed within said housing;
- a rotor, said rotor disposed within said housing, said rotor including retractable vanes that cooperate with the cam plate to pressurize fluid;
- a lower pressure plate disposed within said housing;
- and
- a cover, said cover sealingly engaging said housing at said open end to close said open end, said cover including a side face, said side face contacting said cam plate, said cover including under vane porting said under vane porting providing a fluid path from an outlet port located on said cover to said rotor.
A cover for use with a power steering pump for an automotive vehicle comprising:
- a cylindrical member having a substantially planar side surface and a circumferential outer surface;
- a pair of inlet ports;
- a pair of outlet ports;
- a plurality of fluid passages, said fluid passages forming spaced apart arcuate grooves located about an axis of said cylindrical member;
- and
- a fluid conduit extending between at least one of said outlet ports and at least one of said fluid passages.
A cover for use with a power steering pump for an automotive vehicle comprising:
- a cylindrical member having a planar side surface;
- said cylindrical member having under vane porting, said under vane porting including at least one inlet port, at least one outlet port, at least one fluid passage;
- and
- a fluid conduit extending between said at least one outlet port and said at least one fluid passage for providing fluid flow between said outlet port and said fluid passage.
