摘要： A sealed compressor includes a centrifugal impeller above a rotor to synchronously rotate. A refrigerant rises through a rotor air hole, flows in an upper space, and flows out from a discharge pipe. The centrifugal impeller includes an oil separation plate on the rotor, and plural vanes standing on the oil separation plate, and forms inter-vane flow passages between adjacent vanes, and a vane inner flow passage that guides refrigerant from the rotor air hole to inner entrances of the inter-vane flow passages. Outer exits of the inter-vane flow passages are disposed along an entire circumference, and refrigerant increased in pressure while passing through the inter-vane flow passages flows out from the outer exits to the upper space. The oil separation plate closes a short-circuit passage through which the refrigerant directly flows from the vane inner flow passages to the discharge pipe without passing through the inter-vane flow passages.

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.
