ABSTRACT:
A hydraulic power steering system for a diesel-fueled truck utilizes vehicle fuel as a working fluid. The steering system includes a power steering gear connected to the steerable wheels of the truck. A first pump flows fuel from the truck's fuel tank to both the steering gear and to the engine. A second pump increases the pressure of the fluid to the steering gear to provide power assist. The flow to the steering gear returns to the fuel tank for recirculation.
