PROBLEM TO BE SOLVED: To efficiently suck refrigerator oil accumulated on a bottom of an accommodation portion of an electric motor in a suction chamber to a compression mechanism.SOLUTION: Refrigerator oil O which is accumulated in an accommodation portion of a motor part 4 of a motor chamber 8 by a flow of a refrigerant which is sucked into a suction refrigeration passage 53 from a suction port 55, and flows out to the motor chamber 8 from a refrigerant outlet 57 is blown up into the motor chamber 8 toward a compression mechanism 3 side being an orientation of an opening of the refrigerant outlet 57. Then, the refrigerator oil O which is blown up and misted is sucked into the compression mechanism 3 from a suction port 49 of the compression mechanism 3 which is formed above a liquid level 59 of the refrigerator oil O while being mixed with a gas-phase refrigerant in the motor chamber 8, and sent to a discharge chamber 43 side by the compression mechanism 3 together with the compressed gas-phase refrigerant.SELECTED DRAWING: Figure 3 |
