Claims

[Claims for Utility Model Registration] (1) An electric element and a compression element are housed in a sealed container, and a refrigerant suction line provided in the cylinder of the compression element is connected to an upstream suction port and inside the cylinder. In a device consisting of a downstream branch suction port opened on a wall surface so as to form a plurality of openings on a straight line parallel to the rotation axis of the compression element, the axis of the downstream branch suction port is connected to the upstream suction port. A hermetic rotary compressor, characterized in that the direction of the displacement is moved in a direction approaching the sliding blade side that divides the inside of the cylinder into high and low compression chambers. (2) The deviation of the axis of the branch suction port located on the downstream side is a predetermined inclination state in the direction approaching the sliding vane side of the interior at its opening on the cylinder inner wall surface with respect to the axis of the upstream suction port. A hermetic rotary compressor as set forth in claim 1 of the utility model registration claim.
