Abstract

PURPOSE:To improve the return of oil by forming a cut part on the outer peripheral surface of a cylinder and utilizing said cut part as oil return groove and forming a lower opened port part in the advance direction in the revolution direction of a rotor for an upper opened port part. CONSTITUTION:A cut part 7a is formed on the outer peripheral part of a cylinder 7, and an oil return groove 9 is constituted between the inner peripheral surface of a sealed container 7. A lower opened port part 9b is formed in the advance direction in the revolution direction of a rotor 2 for an upper opened port part 9a of the oil return groove 9. Therefore, even in the high speed revolution, the lubricating oil which revolves in the stepped part between a sealed container and the outer periphery of the cylinder can be returned into the bottom part of the sealed container from the oil return groove by utilizing the turning moment of the lubricating oil.
