PROBLEM TO BE SOLVED: To return the oil separated by an oil separator into a mechanical part on a suction side effectively. SOLUTION: An oil return passage 13 communicating with an oil storage part 9 is provided in a fixed scroll 3, and an oil supply passage 22 is provided in an end plate of a turning scroll 4. By communicating the oil supply passage 22 with the oil return passage 13 during one turning movement of the turning scroll 4, a period for supplying oil to the mechanical part directly during one turning movement is increased to return oil to the mechanical part efficiently.
