<p>PROBLEM TO BE SOLVED: To prevent clogging of a supply oil hole by foreign matter of sludge or the like also avoid deterioration of performance due to a delivery refrigerant leaking out, in a compressor. SOLUTION: In this compressor, constituted by separating lubricating oil from a delivery refrigerant by an oil separator so as to be introduced through a supply oil hole 29 to a radial bearing supporting a drive shaft, the drive shaft is provided with a rotary unit 30 integrally rotated therewith in a position adjacent to the radial bearing. An outflow port 29a of the supply oil hole 29 is opened to an internal peripheral surface of a circular hole 31 fitting this rotary unit 30. A passage 34 for flow amount regulation is constituted by a clearance between the rotary unit 30 and the circular hole 31, to provide a constitution regulating a flow amount coming out to the radial bearing from the supply oil hole 29 while sweeping off foreign matter of sludge or the like from the outflow port 29a of the supply oil hole 29 by rotating the rotary unit 30.</p> |
