摘要

PURPOSE: A check valve of a refrigerant compressor, capable of preventing the counter flow of coolant in the shutdown of a compressor, is provided to prevent the counter flow of coolant of a coolant pipe extending to a compressor by mounting a check valve on a body of the compressors. CONSTITUTION: A check valve of a refrigerant compressor comprises a housing(120), an opening and closing member(130) and a flange(140). The housing comprises a retaining projection and is installed in an outlet formed in the body of a compressor. A refrigerant pipe(150) communicated with the hollow of the housing is fixed to the flange. A male screw part is formed on the outer circumference of the housing. A female screw part is formed on the inner circumference of the hollow formed on the flange.
