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.
