A first passage through which the compressed refrigerant is directly guided from the discharge muffler of the upper frame to the lower space of the electric element in the closed container, and the refrigerant compressed in the other cylinder is discharged from the discharge muffler of the lower frame to the closed container. Provided outside the The guided once in the lower space of the electromotive element again closed vessel after discharged to the outside of the container in the tube 2
The two-cylinder rotary compressor is characterized in that it is provided independently of the passage.
