PROBLEM TO BE SOLVED: To provide a hermetic type compressor of the present embodiment in which much more amount of liquid refrigerant is injected into a cylinder chamber having a more overheated tendency, thereby the cylinder chambers are cooled with high efficiency, and which therefore can exert improved compression performance and reliability, and to provide a refrigeration device with the hermetic type compressor.SOLUTION: The hermetic type compressor is provided in which an electric motor part and a compression mechanism part connected to the electric motor part are housed in a hermetic container, and the compression mechanism part comprises a first cylinder having a first cylinder chamber and a second cylinder having a second cylinder chamber through an intermediate partition plate. The intermediate partition plate includes a lateral hole extending from an outer circumferential surface toward a central part and an injection pipe for use in guiding liquid refrigerant is connected to the intermediate partition plate. The intermediate partition plate further includes: a first injection port for communicating the lateral hole with the first cylinder chamber; and a second injection port for communicating the lateral hole with the second cylinder chamber. The diameter of the first injection port and a diameter of the second injection port are set to be different from each other.SELECTED DRAWING: Figure 1 |
