PURPOSE:To improve oil separating performance and reduce the generation of noise by providing a radial gas passage for discharging a discharge gas, an oil separating chamber, an oil drip hole, and a discharge pipe in between a baffle provided on the outer wall of a compression mechanism and said compression mechanism. CONSTITUTION:A baffle 22 is provided on the outer wall of a compression mechanism 4, and a radial gas passage 21b for discharging a discharge gas, an oil separating chamber 23 for separating oil from the discharge gas, and a discharge pipe 25 for discharging the discharge gas to the outside of an enclosed case 1 are provided in between the baffle 22 and the compression mechanism 4. By this structure, a gas in which oil is mixes is compressed by the compression mechanism part 4, radially flows through the radial gas passage 21b, and is discharged into the oil separating chamber 23. The gas collides against the inner wall of an outer wall plate 22a, to separate oil, which falls along the inner wall and drips downward from an oil drip hole 22b. Thereby, the separation of oil is sufficiently carried out, improving cooling efficiency. Also, since the oil separating chamber 23 serves as a muffler, noise can be reduced.
