Abstract
A power-assisted steering gear assembly in which displacement of a driven member or rack bar (1) on rotation of a driving member or pinion (3) through a steering input (4) is power assisted by means to which fluid pressure is supplied by a rotary valve (6) located on the axial side of the pinion remote from the steering input. One of the valve members (9) of the rotary valve is rotationally rigid with the pinion and the other of the valve members (8) is rotationally rigid with the steering input by way of a torsionally rigid transmission member (14) which extends axially through the pinion, the pinion and the steering input being resiliently coupled by a C-spring (19). A lost motion device (38) may be provided to relieve overstressing of the C-spring. Adjustment means (28) permits selective relative angular adjustment of the steering input and the transmission member without relative rotation of the valve members.
