ABSTRACT:
A rack and pinion power steering system includes a housing within which a rotatable pinion engages a rack to impart movement thereto. The rack is substantially U-shaped having a pair of arms with coaxial openings to slidably receive a rod. The rod extends from the housing to operatively engage a pair of dirigible wheels and the rod is movable relative to the housing when the rack is moved to change the direction of the pair of dirigible wheels. A sleeve on the rod is disposed between the pair of arms and is provided with a valve member to communicate pressurized fluid from a pressure source to a pressure chamber to assist the movement of the rod.
