发明名称 Sealed type rotary compressor
摘要 An object of the present invention is to promote oil separation in a sealed container, thereby decreasing the amount of oil discharged to the outside of a compressor. The compressor comprises discharge hole provided at position facing the end surface of a rotor and through which a compressed refrigerant from first and second rotary compression elements is discharged into the sealed container; and a refrigerant flow path which is extended from a space surrounded with a coil end of a stator projecting from the end surface of the rotor to a rotary compression mechanism side to a space of an air gap between the rotor and the stator, to guide the compressed refrigerant discharged through the discharge hole to an electromotive element opposite to the rotary compression mechanism side. The outlet of this refrigerant flow path opposite to the rotary compression mechanism side faces the inner wall surface of the sealed container, and the volume of a space between the inner wall surface of the sealed container and the electromotive element is 1.5 times or more and 15 times or less that of a space between the rotary compression element and the electromotive element.
