ABSTRACT:
An oil pump which delivers an operating oil to a power steering mechanism of vehicle is designed to reduce the power which is wasted during a high speed operation. A subpump of a reduced capacity having a number of revolutions which varies with a vehicle speed is provided, in addition to a vane pump which delivers an operating oil to the power steering mechanism. A discharged oil from the subpump is delivered to act upon the rear surface of the vanes to enable a pumping action of the vane pump when operating at low speeds while the delivery of the discharged oil to the rear surface of the vanes is interrupted to cease the pumping action of the vane pump, and is delivered to the power steering mechanism when operating at higher speeds.
