PROBLEM TO BE SOLVED: To solve problems in a compressor with a large volume of a high pressure chamber for improving muffler effect, and an introducing hole disposed at a high position for improving lubricating oil separation effect that more lubricant need be enclosed because lubricant is not discharged, but remains at a bottom part of the high pressure chamber, and that remaining lubricant reduces the substantial volume of the high pressure chamber, and reduces muffler effect. SOLUTION: In this compressor, an introducing hole 53 is formed at an upper part of the high pressure chamber 14 to be communicated with a separation chamber 51, and a connection passage 59 is provided at an inlet part of the introducing hole 53 to connect the introducing hole 53 from around the bottom part of the high pressure chamber 14. Lubricant at the bottom part of the high pressure chamber 14 is thus prevented from staying, but it is fed to the introducing hole 53. Increase of necessary quantity of enclosed lubricant or deterioration of muffler effect due to staying of the lubricant in the bottom part of the high pressure chamber 14 can thus be prevented.
