COMPRESSOR

PROBLEM TO BE SOLVED: To provide a compressor of which an oil separation structure can be downsized with higher flexibility in arrangement to prevent separated lubricating oil from being easily brought to the outside.SOLUTION: An oil separation structure of a scroll type compressor includes an oil storage chamber 44 for storing lubricating oil, and an oil separation chamber 41 located above the oil storage chamber 44 and communicated with the oil storage chamber 44. With the oil separation chamber 41, an introduction passage 46 which extends upward from the oil separation chamber 41, an exhaust passage 47, and a supply passage 48 which has a larger passage diameter than that of the introduction passage 46 are communicated. The introduction of refrigerant gas via the introduction passage 46 into the oil separation chamber 41 causes the lubricating oil to be separated from the refrigerant gas, and then the refrigerant gas is exhausted from the exhaust passage 47 via an outlet 12g to the outside of a housing and the lubricating oil is stored via the supply passage 48 in the oil storage chamber 44.
