PROBLEM TO BE SOLVED: To obtain a compressor generating a flow speed gradient near a turned up portion when a first oil separator rotates, and having an oil separation effect higher than that of a conventional one, by separating between a refrigerator oil and a refrigerant utilizing this flow speed gradient. SOLUTION: A protruding portion 4a of a driving shaft 4 protruding from the upper portion of a rotor 3 is equipped with the first oil separator 5. The first oil separator 5 is provided with a flange portion 5b projected in the radial direction of the driving shaft. The flange portion 5b is formed of a doughnut-shaped plate. The plate is turned up at a plurality of locations on the outer periphery to form the turned-up portion 5c, and has a polygonal shape in a planar view. COPYRIGHT: (C)2011,JPO&INPIT |
