ABSTRACT:
A rotary valve in or for a power-assisted rack-and-pinion steering mechanism for a motor vehicle, the rotary valve comprising a valve sleeve, a rotor member rotatable within the valve sleeve, the rotor member and the valve sleeve each having axially extending grooves therein which cooperate to control the flow of fluid under pressure through the valve according to the angular disposition of the rotor member relative to the valve sleeve, and a torsion bar connecting the rotor member to the pinion of the rack-and-pinion steering mechanism, wherein the said pinion is cylindrical and is rigidly connected to the valve sleeve by means of an annular coupling member having an end portion which fits over an end portion of the pinion and has internal teeth which intermesh with the teeth of the pinion, the annular coupling member being brazed or otherwise bonded to both the pinion and to the valve sleeve.
