Abstract

A hermetic compressor includes a hermetic container having a bottom portion in which lubricating oil is stored and an electric motor including a stator and a rotator. The hermetic compressor further includes a drive shaft attached to the rotator and a compression mechanism for compressing refrigerant by using rotation of the drive shaft. The hermetic compressor also includes a rotary pressure increasing mechanism for increasing a pressure of refrigerant gas, the rotary pressure increasing mechanism being arranged on the rotator, and a cylindrical lateral wall for partitioning a space above the electric motor into an outer space and an inner space in a manner that the a cylindrical lateral wall surrounds the rotary pressure increasing mechanism. Finally, the hermetic compressor includes a discharge pipe for allowing the refrigerant to flow out from the inner space into an external circuit that is external to the hermetic container.
