ABSTRACT:
A combined brake and steering system for a vehicle having hydraulic braking and hydraulic steering. A single pump is utilized to supply both the brakes and steering. Two priority valves are arranged to assure that the brakes take precedence and receive an approximately constant flow of hydraulic fluid subject to a predetermined maximum pressure. The steering mechanism also normally receives a constant flow, subject to a different maximum pressure. The fluid from the steering mechanism is recirculated through a reservoir back to the pump. The fluid from the brakes is recirculated to the pump without going through the reservoir.
