REFRIGERANT PRESSURE REGULATING MEMBER OF CATHODE RAY TUBE COUPLER CAPABLE OF AVOIDING REFRIGERANT LEAKAGE OR AIR INFLOW

摘要

PURPOSE: A refrigerant pressure regulating member is provided to prevent a refrigerant leakage or air inflow from or into a coupler housing by maintaining a refrigerant pressure constant. CONSTITUTION: A refrigerant pressure regulating member comprises a main body(110) having a square C-shaped cross section; a coupling portion(120) formed integrally with the open end of the main body and coupled with a side of a coupler housing(11); and a plurality of bent portions(130,140) made of a flexible material and alternately bent along the inner and outer surfaces of the main body. The bent portions are bent or spread in accordance with the expansion or contraction of a refrigerant(13), to thereby change the length of the main body and inner volume of the coupler housing.
