Abstract
An oil supply apparatus supplies oil from an oil pump driven by an engine preferentially to a valve timing control unit. In the oil supply apparatus, a first discharge opening and a second discharge opening having an opening area larger than that of the first discharge opening are formed such that a pressurized region of the oil pump is divided into the two discharge openings. The oil from the first discharge opening is fed to a controlling oil passage through a first discharge port and then supplied to the valve timing controller from the controlling oil passage. The oil from the second discharge opening is fed to a lubricating oil passage through the second discharge port and then supplied to a main gallery from the lubricating oil passage.
