摘要： An oil separator (10) includes: a first separating section (11) that has a cylindrical shape and that has a first inner space in which the refrigerant is capable of swirling; a second separating section (12) that is disposed below the first separating section (11), the second separating section (12) having a cylindrical shape and having a second inner space in which the refrigerant that has flowed out from the first separating section (11) is capable of swirling; an introduction tube (13) that causes the refrigerant to flow out toward an inner wall surface of the first separating section (11) so that a swirl flow of the refrigerant occurs in the first inner space; a delivery tube (14) that delivers the refrigerant from which the refrigerant oil has been separated; and an exhaust pipe (15) that discharges, from the second inner space, the refrigerant oil separated from the refrigerant, the second separating section (12) having a surface (16) that connects the inner wall surface of the first separating section (11) and an upper end of an inner wall surface of the second separating section (12) and that forms a step, and an angle between the surface (16) and the inner wall surface of the first separating section (11) being 90 degrees or smaller and an angle between the surface (16) and the inner wall surface of the second separating section (12) being 90 degrees or smaller.

摘要： A compressor (100) includes a closed casing (101), a compression mechanism (120), a motor (130) and an oil separating member (17A). The oil separating member (17A) rotates together with a shaft (140). The oil separating member (17A) has a peripheral wall (173) and a bottom wall (175) that form a recess (171). An inlet of a discharge pipe (160) penetrating the closed casing (101) is located in the recess (171). A plurality of oil expelling ports (174) are provided in the peripheral wall (173) of the oil separating member (17A) so as to be scattered.
