Abstract
PURPOSE: To conserve energy by a method wherein two kinds of a large capacity pump and a small capacity pump are used as pumps for supplying a pressure fluid, and the large capacity pump is employed when travelling at low speed and the small capacity pump when travelling at high speed.
CONSTITUTION: Oil discharged from the large capacity pump 12 driven by means of an engine 15 through an electromagnetic clutch 14 is forwarded to an accumulator 10 through an oil pressure circuit 17, a throttle 18 and a flow rate control valve, and the steering device is driven. The small capacity pump 13 is operated by means of a motor 25 driven by means of a source battery 22 through a switch 23 and a relay 24, and the actuator 10 is driven by oil discharged from the pump 13. The electromagnetic clutch 14 and the motor 25 can control the switching of switches 31, 23 through an electric controller 36 by signals from a car speed sensor 33, an engine revolution number sensor 34 and a circuit pressure sensor 35, thus operating either of pumps.
