Abstract

The inventive steering system is of the type having an engine, a fluid reservoir, a steering valve unit, an actuator control valve unit, a main fluid pump driven by the engine for pumping the fluid in the reservoir to feed pressure fluid to the steering valve unit and the actuator control valve unit and a priority valve for enabling the pressure fluid to be first supplied to the steering valve unit. Characteristically, the steering system includes an electric motor, a battery selectively connected to the electric motor for supplying electric current to the electric motor, an auxiliary fluid pump rotatingly driven by the electric motor to produce emergency steering fluid to be fed to the steering valve unit and a power supply controller for disconnecting the electric motor from the battery while the main pump produces the pressure fluid and for connecting the electric motor to the battery when no pressure fluid is discharged from the main pump.
