    Abstract: A first pump (21) which supplies a required flow amount for speed ratio control and a second pump (22) which supplies a flow amount which is re-cycled to an oil cooler in order to cool the oil are driven at the same time by a common motor (23). A required discharge amount for the first pump (21) is calculated depending on driving conditions and a required discharge amount for the second pump (22) is calculated depending on driving conditions. The motor (23) is controlled to a rotation speed so that a discharge amount is produced which satisfies the larger of the two required pump discharge amounts calculated above. In such a way, pump rotation speeds are controlled so that the required discharge amount is produced depending on driving conditions which enables reductions in electricity consumption and noise.

    Abstract: When the pressure of a discharge fluid of an electric pump (1) exceeds a predetermined relief pressure, relief valve (6) discharges a part of the fluid to a drain passage (5). A sensor (8, 10, 11) detects a drain flowrate of the drain passage (5), and feedback control of the rotation speed of the electric pump (1) is performed so that the drain flowrate coincides with a predetermined flowrate. Due to this feedback control, the necessary fluid pressure is maintained while suppressing the drain flowrate to the minimum.
