Abstract: A compressor is provided that may include a passage separator (8) provided between an electric motor drive (2) and a compression device (3) to separate a refrigerant passage from an oil passage. The passage separator (8) may include a first partition wall (82) and a second partition wall (84). The first partition wall may be disposed between an inner circumferential surface of a casing (1) and a discharge hole (314b,322a) of the compression device, and the second partition wall may be disposed between the discharge hole and a balance weight (7). Accordingly, the refrigerant passage may be separated from the oil passage between the compression device and electric motor drive, thereby efficiently recovering oil to an oil storage space (V3).
