Abrégé
Provided is a compressor and the like with high reliability. A compressor (100) includes a cylindrical oil ring (15) provided between a compression mechanism portion (2) and an electric motor (6). A stator (6a) of the electric motor (6) is provided with at least one oil passage that connects one side of the stator (6a) with the other side of the same in an axial direction. An upstream end of a discharge pipe (Pb) is located radially inward of the oil ring (15), and the oil ring (15) is provided radially inward of the oil passage when viewed cross-sectionally. In the cross-sectional view including a part where the discharge pipe (Pb) is inserted into the oil ring (15), at least a part of the oil passage overlaps with the oil ring (15) in a radial direction.Classes IPC ?
