A compressor is provided with a bypass device (30) which is affixed positioned over a discharge hole (5b) in a main shaft (5) and which regulates the amount of oil discharged from the discharge hole. This bypass device has: a housing (31) having formed therein a hollow section (36) into which oil flows from the discharge hole, the housing (31) also having a bypass hole (37) from which the oil having flowed into the hollow section is discharged; a slide member (40) moving over the bypass hole and adjusting the degree of opening of the bypass hole; and a pressing member (41) for pressing the slide member to one side of the housing from the other side thereof. When moved radially by centrifugal force during the rotation of the main shaft, the slide member divides the hollow section into a first space (36A) on the main shaft side and into a second space (36B) on the pressing member side, and a pressure equalization passage (38) for connecting the first space and the second space is formed in the hollow section of the housing. |
