PROBLEM TO BE SOLVED: To prevent a pressure pulsation of lubricating oil from being transmitted to an oil separator side from a throttle flow passage.SOLUTION: In a compressor, a fixed side oil supply flow passage 127 and a movable side oil supply flow passage 114 are intermittently communicated with each other in accordance with revolving movement of a movable scroll 11, and lubricating oil from an outlet of an oil separator is supplied to a lubrication object portion or the like through a throttle flow passage 34b of a return pipe 34, the fixed side oil supply flow passage 127, and the movable side oil supply flow passage 114 in accordance with the communication. The return pipe 34 has the throttle flow passage 34b having flow passages 130 and 131. When a pulsation advances to the flow passage 131 through the flow passage 130, the pulsation is transmitted to an oil piping side while dispersing to a radial outer side in the flow passage 131.SELECTED DRAWING: Figure 3 |
