ABSTRACT:
A steer wheel control system having a centering unit for holding center by resisting off-center movement of the steered wheels of a vehicle and returning them to a selected center position after each such movement, and a trim unit for remotely varying the selected center position. The resistance and return forces may also be varied remotely. A plurality of passages and check valves make the trim unit operable by a single solenoid valve mounted in an externally accessible socket within an intermediate head between the trim unit and the centering unit. An orifice assembly between a fluid accumulator and the centering unit prevent overly rapid off-center movements during tire blowouts.
