Beschreibung
Zusammenfassung:	PURPOSE: A hermetic compressor is provided to reduce frictional loss by smoothly supplying oil to a second bearing, which is located on the upper part of a crank shaft. CONSTITUTION: A hermetic compressor comprises a hermetic container(100), a driving unit, a crank shaft(230), a compression unit, a first bearing(400), and a second bearing(500). The driving unit is installed in the internal space of the hermetic container. The crank shaft is coupled to the driving unit and comprises an oil flow path and an eccentric unit. The eccentric unit operates with the compression unit to compress refrigerant. The compression unit is coupled to the crank shaft to compress refrigerant. The first bearing is fixed to the compression unit and supports the crank shaft.
