Hermetic reciprocating compressor
Disclosed herein is a compressor in which oil retained in a hermetic case may be raised through an inner circumferential surface of a rotating shaft. The rotating shaft is provided with a hollow portion, and a fixation shaft with a spiral wing is inserted into the hollow portion to raise oil. Also, a spiral groove is formed on an outer circumferential surface of the rotating shaft to cause the raised oil to descend and lubricate the outer circumferential surface of the rotating shaft, and the hollow portion and the spiral groove are connected to each other via a guide passage.
