ROTARY COMPRESSOR

摘要

PROBLEM TO BE SOLVED: To separate misty lubricant injected from a through hole from refrigerant gas for lowering the oil rate (volume of oil in refrigerant) that flows into a discharge pipe provided in a lid chamber and inhibits heat exchange function of a unit equipped with a compressor. SOLUTION: The upper side of a notch where the through hole is formed is covered like a canopy. The injection direction of refrigerant gas containing lubricant is changed to make the refrigerant hit on an inner wall of a case of a sealed container, so that the lubricant is separated. The oil rate of the refrigerant flowing into a discharge hole of the lid chamber is thus lowered. COPYRIGHT: (C)2004,JPO&NCIPI
