<p>RACK AND PINION POWER STEERING DEVICE A rack and pinion power steering device includes a housing within which the pinion engages the rack to impart movement to the rack upon rotation of the pinion, The rack includes a bore for slidably receiving a pair of plugs which support the rack and a rod which extend through the plugs and housing to engage a pair of dirigible wheels. The plugs cooperate with the rod to form pressure chambers and a valve member carried by the rack cooperates with projections on the rod to communicate pressurized fluid from a pressure source to either of the pressure chambers whereupon the pressurized fluid wherein urges the rod to move relative to the housing. The rod also provides for communication of pressurized fluid from the pressure source to the valve member via a passage therein.</p> |
