Abstract:
Provided is, e.g., a compressor with a high reliability. A compressor (100) includes a hermetic container (1) sealed with lubricant oil, an electric motor (6) placed inside the hermetic container (1) and having a stator (6a) and a rotor (6b), a crankshaft (3) configured to rotate integrally with the rotor (6b), a compression mechanism (2) configured to compress refrigerant in association with rotation of the crankshaft (3), a discharge pipe (Pb) configured to guide the refrigerant compressed in the compression mechanism (2) to the outside of the hermetic container (1), and a tubular oil ring (15) provided between the compression mechanism (2) and the electric motor (6). A cutout (s1) is, at a lower portion of the oil ring (15), provided as a first insertion portion into which the discharge pipe (Pb) is inserted.
