Summary:PROBLEM TO BE SOLVED: To add a function for separating oil from working fluid in a principal working fluid passage to the components composing an existing compressor. SOLUTION: The principal working fluid passage is provided so as to flow the working fluid, which has been flowed therein from an inlet port 28 of the compressor 1, outward from an outlet port via a crankcase 10, a low pressure chamber 25, a compression chamber 16, and a high pressure chamber 26 in this order. A driving shaft 12 is provided with passages 29, 30 having side holes 32, 34 opened in the radial direction of the driving shaft 12. The passages 29, 30 compose a part of the suction side passage in the principal working fluid passage. When the working fluid flows through the side holes 32, 34, the oil is separated from the working fluid by the centrifugal separating effect due to the rotation of the driving shaft 12.
