COMPRESSOR

摘要

An oil-separation mechanism (40) that separates oil from a refrigerant gas outputted from a compression mechanism (10) is provided. Said oil-separation mechanism (40) has: a cylindrical space (41) that causes the refrigerant gas to flow in a circular manner; an inflow section (42) via which the refrigerant gas outputted from the compression mechanism (10) is directed into the cylindrical space (41); an outlet (43) via which refrigerant gas from which oil has been separated out is outputted from the cylindrical space (41) to one intra-container space (31); and a discharge port (44) via which the separated-out oil is discharged from the cylindrical space (41) to another intra-container space (32). This improves the efficiency and volumetric efficiency of an electric-motor unit (20) and allows low-oil circulation.
