PURPOSE:To dispense with piping, improve reliability, reduce vibration and noise and lower a cost by assembling an unload valve in a pump body. CONSTITUTION:The captioned oil pump houses an unload valve consisting of a flow control valve 48, a check valve 58 and a solenoid valve 64 in a pump body 6. Thereby, there is no need for separately providing an unload valve, to dispense with piping, enabling a compact system to be formed while lowering a cost. Also, vibration and noise caused by surge pressure at the time of unloading can be removed. |
