Abstract
An oil supply apparatus includes a variable capacity oil pump 81, a hydraulic pressure detection section 50a detecting a hydraulic pressure in an oil supply passage 5, an oil control valve 84 changing an oil discharge amount, a mechanical relief valve 81z partially discharging oil to outside of the oil supply passage when a discharge hydraulic pressure of the oil pump exceeds an upper limit pressure, a temperature detection section 50b detecting a temperature of an engine, and a control section 60. When the temperature is equal to or higher than a set temperature, the oil control valve is subject to feedback control such that the hydraulic pressure matches a target hydraulic pressure. When the temperature is lower than the set temperature, the feedback control is prohibited, and the oil control valve is controlled such that an oil discharge amount becomes a maximum amount.
