Hydraulikpumpenanlage

摘要

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.
