Abstract: A hydraulic fluid pump (10), including a housing (12), a pumping apparatus (14), an inlet (16), a pressure chamber (17), an outlet (18), a bypass valve (20) and a diffuser (24). Wherein cavitation is reduced by using the diffuser (24) to supercharge fluid from the outlet (18) to increase the static pressure of the fluid entering the pumping apparatus (14). And wherein the inlet (16) and the diffuser (24) are designed to minimize the complexity, cost and packaging considerations of the hydraulic fluid pump (10).

Abstract: A fluid conduit connecting apparatus allows various final assembly orientations of the fluid supply line (52) to a pump housing (16). The fluid conduit connecting apparatus includes a collar (12) having a first side (22) with teeth (26) and a tube (14) with at least one tooth (60) for orienting the tube (14) relative to the collar and housing when finally installed. The tube (14) further includes at least one retaining barb (82) for positively retaining the tube (14) in a fluid passage (72) of the housing (16).

Abstract: A hydraulic apparatus as used for providing fluid to a steering gear of an automotive vehicle includes a housing (10) having a valve bore (14) housing a relief valve spool (94) disposed therein and slidable between a first and second position. A discharge connector (88) is disposed on a first end of the valve bore (14) and forms a fluid passage for communicating fluid through the first end of the valve bore to a power steering actuator. An annular retainer (90) is disposed in the valve bore between the first position of the spool valve (94) and the discharge connector (88). The annular retainer includes an outer periphery (130) sized for interference fit engagement with said valve bore (14) for retaining the spool valve (94) within the valve bore (14) when the discharge connector (88) is removed from the first end of the valve bore.
