A rack and pinion power steering device includes a housing which defines a cavity and the housing communicates with a pressure source. A pinion extends into the housing cavity to engage a rack which is movably supported by a sleeve member. The rack engages a valve member to control communication from the pressure source to a pair of chambers within the sleeve member. The pair of chambers are separated by a partition and a pair of rods are fixedly secured to the partition. Extending from the housing the pair of rods cooperate with dirigible wheels to control the direction of the dirigible wheels. The housing includes portions which slidably support the sleeve member and the pair of rods and partially define the pair of chambers. The sleeve member and pair of rods are movable relative to the housing in response to pressure within the pair of chambers. |
