    摘要： A two-cylinder type two-stage compression rotary compressor has an electric motor portion in a closed container and upper and lower cylinders driven by a rotating shaft of the electric motor portion; the insides of the respective cylinders are partitioned by upper and lower vanes and upper and lower rollers which are fitted to upper and lower eccentric portions provided to the rotating shaft to eccentrically rotate in the upper and lower cylinders; a lower stage side compression portion for sucking and compressing a refrigerant gas to be discharged, a high stage compression portion, and an intermediate partition plate provided between the both compression portions to insert the rotating shaft therethrough are included; the upper and lower eccentric portions provided to the rotating shaft have a phase difference of 180 degrees; a connecting portion for connecting the both eccentric portions has such a non-circular cross-sectional shape such as that the thickness in a direction orthogonal to an eccentric direction is set larger than the thickness in the eccentric direction; the cross-sectional area is larger than the cross-sectional area of the rotating shaft.

    摘要： Refrigerant compressed by a first stage compression elements (30) run by a motor (20) is discharged in the closed container (10) via a silencer chamber (35) to cool the motor (20) before the refrigerant is led to a second stage compression element (40). The refrigerant is discharged from the second stage compression element (40) out of the compressor after it is further compressed in the second compression element (40). Thus, the motor (20) is cooled in a simple cooling mechanism during normal operation of the compressor.
