Claims

[Scope of utility model registration request]

In a hermetically sealed rotary compressor, a compressor element 6 is housed in an airtight container 1, and a compression element 6 is housed in an upper part of an electric element consisting of a stator 2 and a rotor 3, and a compression element 6 is connected to a lower part of the electric element by a rotating shaft 7 driven by an electric element. Above the vicinity of the upper end of the frame 9 of 6,
A discharge gas passage 4 is provided in the center of the rotating shaft 7, one end of which is connected to the lower end of the discharge gas passage 4, and the other end is connected to the lower end of the rotor core 3a on the lower high pressure chamber 15 side and the upper end of the frame 9. A hermetic rotary compressor characterized in that a communication hole 17 is provided in between and the upper end of the discharge gas passage 4 is opened into an upper cylinder pressure chamber 16.
