Abstract: The present invention provides a compressor capable of supplying a lubricating oil stably to the refrigerant suction side of a compression section even if a lubricating oil is discharged into an oil storage chamber with great force. In this compressor, the oil storage chamber is provided so that two chambers of a first oil storage chamber and a second oil storage chamber communicate with each other, the lubricating oil discharged from a separation chamber is received by the first oil storage chamber, and the lubricating oil is supplied from the second oil storage chamber to the refrigerant suction side of the compression section. Therefore, even if the oil surface of the first oil storage chamber is disturbed by the force of the lubricating oil discharged from the separation chamber, the lubricating oil can always be supplied stably without hindrance to the supply of lubricating oil to the refrigerant suction side of the compression section.
