Abstract
A hermetic motor compressor for compressing refrigerant gas in air conditioners or refrigerators. The hermetic motor compressor includes a motor compressor disposed in a closed housing and consisting of a motor section and a compressor section formed integrally with each other. The compressor section has a cylinder head cover, discharge silencer and discharge tube through which the compressed refrigerant gas is discharged to the outside. The cylinder head cover, discharge silencer and discharge tube are covered by heat insulating members with suitable spaces provided therearound. Heat radiation from the discharge system is therefore prevented by the spaces as well as by the heat insulating members, so that the temperature rise of refrigerant gas in the closed housing is avoided to ensure a higher volumetric efficiency of the compressor.
