Abstract
A hydraulic oil supply apparatus includes an oil pump discharging hydraulic oil, a common oil passage through which the discharged hydraulic oil flows, a first oil passage branched from the common oil passage to supply the hydraulic oil to a valve opening and closing timing control apparatus, a second oil passage supplying the hydraulic oil to a main gallery, and a flow control valve decreasing a volume of hydraulic oil flowing through the first oil passage with an increase of hydraulic pressure of the hydraulic oil discharged from the oil pump so as to increase a volume of hydraulic oil flowing through the second oil passage. In the hydraulic oil supply apparatus, hydraulic pressure generated from the hydraulic oil passing through a valve body of the flow control valve is applied to the valve body as a force against a force of a biasing member that biases the valve body.
