ABSTRACT:
A steering control valve and worm nut centering device for a power steering booster mechanism control valve is provided comprising a flexure rod carried either by the double-acting piston member or the worm nut member and extending between those members or into the valve spool. The overall construction is conventional and well known, the particular feature of the invention being a flexure rod which is adjustable translationally or rotatively, in various modifications, to center the valve spool of the control valve and to center the worm nut. The flexure rod can be predetermined as to length, taper, alloy, and other design factors so as to flex to give a desired increase in road resistance feel substantially over and above that afforded by the usual size of reaction chambers and centering spring conventionally associated with the valve spool. Thus, a flexure characteristic curve of extent of flexure versus degree of steering provides a sharp increase in road resistance simulation as the steering spindle is turned.
