Abstract
A rack and pinion assembly includes a rack bar having a longitudinal axis along which it is displaceable in a rack bar housing. A pinion is rotatably mounted in the housing and has teeth which engage with helically formed teeth in a rack of the bar so that upon rotation of the pinion, the rack bar is displaced longitudinally relative to the housing. A control mechanism communicates between the rack bar and the housing and rotates the bar about its longitudinal axis and relative to the housing in response to the longitudinal displacement of the bar by the pinion.
