Claim:
1. A compressor, comprising: a rotary shaft: a compression mechanism that includes a compression chamber and that is configured to compress refrigerant gas in the compression chamber in response to rotation of the rotary shaft; a discharge port connected to the compression chamber; a cylindrical discharge housing member including an end wall that is perpendicular to an axial direction of the rotary shaft, and a circumferential wall; a discharge chamber that is provided in the cylindrical discharge housing member and that is configured to receive the refrigerant gas compressed in the compression chamber and discharged via the discharge port; an oil separation chamber that is provided in the cylindrical discharge housing member, the oil separation chamber accommodates an oil separation tube that is configured to separate lubricant contained in the refrigerant gas discharged to the discharge chamber from the refrigerant gas; a cylindrical wall that is provided on the end wall of the cylindrical discharge housing member and that extends in a radial direction of the rotary shaft, the cylindrical wall separates the discharge chamber and the oil separation chamber from each other; and a partition that is provided in the discharge chamber, the partition is continuous with and protrudes from the cylindrical wall in the axial direction of the rotary shaft, wherein the cylindrical wall and the end wall define the oil separation chamber therebetween, the cylindrical wall bulges into the discharge chamber in the axial direction of the rotary shaft and extends from an upper section of the discharge chamber toward a lower section of the discharge chamber, and the cylindrical wall includes, at a position corresponding to the upper section, a communication hole connecting the discharge chamber to the oil separation chamber, the partition extends from the upper section of the discharge chamber toward the lower section of the discharge chamber and defines a first space that communicates with the discharge port and a second space that communicates with the communication hole in the discharge chamber, and the first space and the second space are connected to each other at least at the lower section of the discharge chamber through a clearance between the partition and the circumferential wall.
