Abstract
A power assisted steering gear has a toothed part 1 such as a pinion coupled through a torque responsive rod 12 to an input shaft 4 so that rotation of the shaft 4 rotates the pinion 1 to drive an output member having a servo motor associated therewith. Fluid flow to the servo motor for power assistance is controlled by a valve 6 by displacement of component parts of the valve during relative rotation between the input shaft 4 and the pinion 1 as permitted by the rod 12. The toothed part 1 is rotatably borne in the housing by a bearing 16 which journals a shaft part 19 formed by an extension of the rod 12 through the toothed part 1. The valve 6 and pinion 1 may form a unified assembly 7 carried on the shaft 4 and which is inserted into and removed from the housing 3 in unit manner.
