US Patent 7736136 Compressor including separation tube engagement mechanism

The present invention provides a compressor capable of arranging a refrigerant discharge port regardless of the location of a separation chamber. In this compressor, a separation tube is pressed in through an opening of the separation chamber, and by engaging a regulating ring with an engagement groove provided in the inner wall of the separation chamber, the movement of the separation tube in the anti-insertion direction is regulated. Therefore, unlike the conventional compressor, a refrigerant discharge pipe for regulating the movement of the separation tube in the anti-insertion direction need not be connected to the upper part of the separation tube, and the refrigerant discharge port can be arranged freely regardless of the location of the separation section.
