Abstract: A power steering assembly and method of retrofitting therefore includes a housing having a cavity defined therein. A drive member extends axially into the cavity and a first piston and a second piston are received in the cavity for axial reciprocation therein. The first and second pistons define at least in part first and second pairs of chambers. The first pair of chambers receive fluid under pressure to move the first and second pistons toward one end of the housing to rotate the driven shaft in a first direction. The second pair of chambers receive fluid under pressure to move the first and second pistons toward the other end of the housing to rotate the driven shaft in a second direction opposite the first direction.

Abstract: A power steering gear with a hydraulic valve and a detent mechanism allows simultaneous hydraulic and mechanical balancing. The hydraulic valve is rotatively separate from the detent mechanism to allow separate balancing. The hydraulic valve is integral with an input member. The detent mechanism is integral with a stub shaft which is concentric with but rotatively independent of the input member. The stub shaft and the input member are rotatively fixed to each other when both the hydraulic valve and the detent mechanism are balanced.
