ABSTRACT:
A lubricating groove not communicating with other oil passages and extending in the circumferential direction is provided on the side surface of a cam ring. The central portion in the circumferential direction of the lubricating groove is located at the center of the suction side, and both ends of the lubricating groove reach the positions beyond a straight line joinning the upper and lower dead points. As a result, the side surface of the cam ring of the variable-displacement vane pump is prevented from seizing.
