ABSTRACT:
A hydraulic pressure source device for supplying an actuating hydraulic pressure to an automotive booster, having an accumulator and a hydraulic pump, the pump being interposed in a low-pressure oil passage leading from the control valve of a hydraulic power steering device to an oil tank. In the oil passage is also interposed an electromagnetic valve which is adapted to be opened and closed under control of an intermittent actuator which intermittently energizes the electromagnetic valve when sensing a pressure in the accumulator below a preset level. The pump is actuated by the hydraulic oil which is discharged into the low-pressure oil passage after having actuated the control valve through intermittent opening and closing operation of the electromagnetic valve to replenish the accumulator with the hydraulic pressure. A restrictor may be disposed in the low-pressure oil passage to release the hydraulic oil to an oil tank when the electromagnetic valve is closed, so as to establish a pressure difference between the low-pressure oil passage and a high-pressure oil passage connecting between the control valve and a main hydraulic pump.
