<p>In a compact oil supply apparatus, a valve body includes a first land and a second land protruding along the radial direction of the valve body about the axis thereof, and a small-diameter portion continuously connecting the first land with the second land and having a diameter smaller than at least the outer diameter of the first land and the second land. Rotational speeds of a rotor are set as a first rotational range, a second rotational range and a third rotational range in the ascending order. At the time of the first rotational range, work oil from a second discharge port is fed to a first oil passage via the small diameter portion. At the time of the second rotational range, the work oil from the second discharge port is fed to a return oil passage via the small diameter portion. At the time of the third rotational range after the second oil passage is blocked relative to the return oil passage by the second land, the work oil from the second discharge port is fed to the first oil passage.</p> |
