PROBLEM TO BE SOLVED: To provide a compressor in which high efficiency and improved volumetric efficiency of an electric-motor unit are achieved, and low-oil circulation is achieved.SOLUTION: An oil-separation mechanism section 40 that separates oil from a refrigerant gas discharged from a compression mechanism section 10 is provided. The oil-separation mechanism section 40 has: a cylindrical space 41 that causes the refrigerant gas to orbit; an inflow section 42 via which the refrigerant gas discharged from the compression mechanism section 10 is directed into the cylindrical space 41; an outlet 43 via which refrigerant gas from which oil has been separated out is discharged from the cylindrical space 41 to one intra-container space 31; and a discharge port 44 via which the separated oil is discharged from the cylindrical space 41 to another intra-container space 32. The compression mechanism section 10 includes a fixed scroll 12, an orbiting scroll 13 arranged to oppose the fixed scroll 12, and a main bearing member 11 for pivotally supporting a shaft 5 for driving the orbiting scroll 13, and the cylindrical space 41 is characteristically formed with the fixed scroll 12 and the main bearing member 11. |
