PROBLEM TO BE SOLVED: To efficiently separate an oil component in a compressed gas by a centrifugal separation type oil separator even if a flow speed of the compressed gas is low.SOLUTION: A swirl flow of a compressed refrigerant 13 which flows into an oil separation chamber 7f from a flow-in port 7g of an oil separator 7e is made to collide with a fin 7q of a cylinder member 7k which extends on a route of the swirl flow, and the cylinder member 7k is rotated by a rotation thrust force which is obtained by the fin 7q from the swirl flow. A lubricant 11 is separated from the swirl flow of the compressed refrigerant 13 which has collided with the fin 7q by a centrifugal force, and made to adhere on an internal peripheral wall 7h of the oil separator 7f. Furthermore, the lubricant 11 in the compressed refrigerant 13 which has adhered on a peripheral face 7n of the cylinder member 7k, an internal peripheral edge of a communication hole 7p and an internal peripheral face of the cylinder member 7k is scattered to the outside of the cylinder member 7k by the centrifugal force which is generated by the rotation of the cylinder member 7k, and made to adhere on the internal peripheral wall 7h of the oil separation chamber 7f. The lubricant 11 which has adhered on the internal peripheral wall 7h of the oil separation chamber 7f is made to drip to an oil sump 7d of a compression chamber 7a.SELECTED DRAWING: Figure 3 【課題】圧縮気体の流速が低くても遠心分離式の油分離器により圧縮気体中の油分を効率よく分離する。【解決手段】油分離器７ｅの流入口７ｇから油分離室７ｆに流入した圧縮冷媒１３の旋回流を、その経路上に延出した円筒部材７ｋのフィン７ｑに衝突させ、旋回流からフィン７ｑが得た回転推進力で円筒部材７ｋを回転させる。フィン７ｑに衝突した後の圧縮冷媒１３の旋回流から潤滑油１１を遠心力により分離させて油分離室７ｆの内周壁７ｈに付着させる。また、円筒部材７ｋの周面７ｎや連通孔７ｐの内周縁、円筒部材７ｋの内周面に付着した圧縮冷媒１３中の潤滑油１１を、円筒部材７ｋの回転により発生した遠心力により円筒部材７ｋの外側に飛散させて油分離室７ｆの内周壁７ｈに付着させる。油分離室７ｆの内周壁７ｈに付着させた潤滑油１１は圧縮室７ａの油溜まり部７ｄに滴下させる。【選択図】図３
