Patent ID: 7798787

Claim:
An internal intermediate pressure multistage compression type rotary compressor comprising an electric element in a hermetic shell case, and first and second rotary compression elements being positioned under the electric element and driven by a rotary shaft of the electric element, wherein refrigerant compressed by said first rotary compression element is discharged into the hermetic shell case, and the discharged intermediate pressure refrigerant is compressed by said second rotary compression element, said multistage compression type rotary compressor further comprising: a plurality of sleeves including at least a first sleeve and a second sleeve, the first sleeve being fixed to a side surface of the hermetic shell case at an upper end of a stator of the electric element, the second sleeve being fixed to a side surface of the hermetic shell case at a position below the upper end of the stator of the electric element; and a refrigerant introduction pipe which is opened to the interior of the hermetic shell case over the electric element and introduces the refrigerant in the hermetic shell case into the second rotary compression element through an outside of the hermetic shell case, wherein an inlet of one end of the refrigerant introduction pipe is inserted into and connected to the first sleeve, wherein another end of the refrigerant pipe is inserted into and connected to the second sleeve, wherein a part of the inlet inside the first sleeve is positioned under the upper end of the stator of the electric element and another part of the inlet inside the first sleeve is positioned over the upper end of the stator.
