Abstract

Disclosed is a hermetic compressor which has a simplified structure and can adequately separate a coolant from a lubricating oil, and efficiently discharge the coolant to the exterior of a hermetic container. A discharge passage (90) is provided either within a scroll unit (30) and a main shaft frame (14) or between the inner wall surface of a drum portion (3) of a hermetic container (2) and the scroll unit and the main shaft frame in such a way as to conduct the coolant and lubricating oil directly to a stator (8) of an electric motor (6). An oil-separation plate (96) for separating the lubricating oil from the coolant conducted from a discharge passage is provided at the top of the stator, and a discharge pipe (72) for discharging the coolant from which the lubricating oil has been separated to the exterior of the hermetic container is provided in the drum portion arranged below the main shaft frame.
