    摘要: A check valve provided makes it possible to operate a vane pump smoothly even at the start of the vane pump by maintaining an oil pressure in backpressure oil passages inside the vane pump while the vane pump is stopped. The check valve opens at the point in time when an oil pressure control device, to which a working fluid is supplied from the vane pump, has been filled with the working fluid and the oil pressure in discharge oil passages communicating with the oil pressure control device has risen and exceeded the oil pressure in the backpressure oil passages. Thus, the check valve is prevented from opening and closing repeatedly, so that the durability of the check valve is improved.

    摘要: A vehicle drive-force transmitting apparatus including: a mode switching clutch; a torque converter; a lock-up clutch included in the torque converter; a switching solenoid valve configured to output a switching pressure for switching an operating mode of the mode switching clutch between a one-way mode and a lock mode; and a lock-up clutch control valve configured to switch an operating state of the lock-up clutch between an engaged state and a released state. The mode switching clutch is to be placed in the lock mode when the switching pressure is supplied from the switching solenoid valve to the mode switching clutch. The lock-up clutch control valve is configured to receive the switching pressure supplied from the switching solenoid valve, and to switch the operating state of the lock-up clutch to the released state when the switching pressure is supplied to the lock-up clutch control valve.

    摘要: A vane oil pump includes a rotor including a plurality of slits, a housing having an inner circumferential cam surface such that a first pump unit and a second pump unit taking in and discharging oil in accordance with rotation of the rotor are separately disposed in a rotational direction of the rotor, a plurality of vanes respectively fitted in the slits of the rotor, and a pressure adjusting device configured to adjust a second discharge pressure of the second pump unit to a lower pressure than a first discharge pressure of the first pump unit. A back pressure groove is disposed on the housing and is provided to supply back pressure oil to a bottom portion of each slit.

    摘要: A vehicle hydraulic device is provided with an electric motor-driven oil pump and a shuttle valve, so that a vane pump operates smoothly, even at the start, with a backpressure applied from the electric motor-driven oil pump to the vanes. Even when the oil pressure of a working fluid discharged from the vane pump exceeds the backpressure inside vane housing grooves, the working fluid flows from a vane pump discharge oil passage to a backpressure oil passage, so that the vanes are not pushed into the housing grooves. Thus, it is possible to reduce the fluctuations in discharge amount of the vane pump due to fluctuations in oil pressure of the vane pump discharge oil passage during operation of the vane pump.
