ABSTRACT:
Two fluid circuits respectively supply pressurized fluid from engine driven and vehicle pumps to separate servomotors in a vehicle steering system for steering operation during vehicle travel. Both fluid circuits are connected to the engine driven pump alone during vehicle standstill by a reversing valve which is shifted to a travel position by pressure output of the vehicle driven pump.
