Title:
OIL SUPPLY DEVICE
Document Type and Number:
WIPO Patent Application WO/2012/077458
Kind Code:
A1
Abstract:
A compact oil supply device has a configuration in which a valve element is provided with a first land and a second land which each protrude in the radial direction of the valve element with the axis center of the valve element as the center, and a small-diameter part which connects the first land and the second land in an axial direction and has a diameter smaller than the outer diameters of at least the first land and the second land. When a first rotation range, a second rotation range, and a third rotation range are set in ascending order of the number of rotations of a rotor, the oil supply device is configured to feed operating oil from a second discharge port to a first oil path via the small-diameter part in the first rotation range, feed the operating oil from the second discharge port to a return oil path via the small-diameter part in the second rotation range, and feed the operating oil from the second discharge port to the first oil path in the third rotation range after a second oil path is shut off from the return oil path by the second land.
