CLOSED ELECTRIC COMPRESSOR

摘要

PROBLEM TO BE SOLVED: To provide a closed electric compressor with the excellent assembling property capable of preventing a leak of a lubricating oil and reducing the noise. SOLUTION: An outer edge shape of a curved surface of a discharge muffler to be manufactured by sheet metal press working is formed of plural curves having a different curvature and not including a straight line. With this structure, flatness of a flat part is obtained even in a complicated shape, and the refrigerant gas circulates all over the inside of a closed container so as to recover the lubricating oil and eliminate the pressure pulsation of the discharge refrigerant gas.
