<p>A compressor capable of preventing an oil feed hole from being clogged by foreign matter such as sludge and avoiding a performance from being lowered due to leakage of delivered refrigerant, wherein lubricating oil separated from the delivered refrigerant by an oil separator is led to a radial bearing supporting a drive shaft through the oil feed hole (29), a rotary body (30) rotating integrally with the drive shaft is provided on the drive shaft at a position adjacent to the radial bearing, a flowout port (29a) of the oil feed hole (29) is opened to an inner peripheral surface of a circular hole (31) having the rotary body (30) fitted thereto, a path (34) for flow control is formed by a clearance between the rotary body (30) and the circular hole (31) and, while a flow delivered from the oil feed hole (29) to the radial bearing is controlled, foreign matter such as sludge is swept out from the flowout port (29a) of the oil feed hole (29) by the rotation of the rotary body (30).</p> |
