Claims

[Scope of utility model registration request]

(1) Between the inner wall surface of the sealed container and the stator core portion of the internal electric element, the above-mentioned opening is blocked from other than the upper empty space inside the container, and the lower end opening is opened into the lubricating oil at the inner bottom of the container. A hermetic electric compressor characterized by comprising a return passage for separated lubricating oil.

(2) A series of separated lubricating oil return passages with open upper openings in the upper cavity of the sealed container are inserted between the inner wall surface of the sealed container and the outer peripheral surface of the stator core of the internal electric element. A hermetic electric compressor according to claim 1, which is formed of a return pipe.

(3) One half of the return passage for the separated lubricating oil opened in the upper cavity of the sealed container is formed in the gap between the inner wall surface of the sealed container and the stator core of the internal electric element, The closed type electric compression according to claim 1, which is formed by a gap between an upright wall provided on the frame of the compression element and the inner wall surface of the closed container, which is brought into contact with the end face of the unit.
