    摘要: There is provided an internal intermediate pressure multistage compression type rotary compressor capable of reducing a height dimension while reducing the amount of oil to be discharged outside. An electric element and first and second rotary compression elements which are driven by a rotary shaft of the electric element disposed under the electric element are provided in a hermetic shell case. There is provided a refrigerant introduction pipe for introducing refrigerant in the hermetic shell case over the electric element into the second rotary compression element through an outside of the hermetic shell case. There is provided an oil path provided in the rotary shaft for discharging oil through an oil discharge port which is positioned at the upper end of the rotary shaft. The refrigerant introduction pipe is provided such that a part of an inlet of the refrigerant introduction pipe is positioned under the upper end of a stator of the electric element.
