Abstract
An object is to execute sure oil supplying to a second rotary compression element in a horizontal type compressor equipped with the second rotary compression element in which pressure becomes higher than that in an airtight container. A horizontal type rotary compressor of a multistage compression system comprises a driving element and a compression mechanism section driven by the driving element in a horizontal type airtight container. The compression mechanism section is constituted of first and second rotary compression elements. A refrigerant compressed by the first rotary compression element is discharged into the airtight container, and the discharged refrigerant of intermediate pressure is further compressed by the second rotary compression element to be discharged. A gist is that an oil supply passage is formed in a cylinder of the second rotary compression elementto communicate a low-pressure chamber of the cylinder with a bottom part in the airtight container.
