COMPRESSOR AND METHOD OF LUBRICATING THE COMPRESSOR

摘要

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 (23) is led to a radial bearing (10) supporting a drive shaft (8) through the oil feed hole (29), a rotary body (30) rotating integrally with the drive shaft (8) is provided on the drive shaft (8) at a position adjacent to the radial bearing (10), lubricating oil is fed to the radial bearing (10) through a clearance between the outer peripheral surface of the rotary body (30) and the inner peripheral surface of a circular hole (31) having the rotary body (30) fitted thereto, a lubricating oil feeding groove (32) communicating with an outflow hole of the oil feed hole (29) and an inflow port of a release hole (33) alternately each time the rotary body (30) is rotated is provided in the outer peripheral surface of the rotary body (30), and lubricating oil flowing in from the oil feed hole (29) is released intermittently to a drive chamber (7) through the groove (32) and the release hole (33).
