Patent ID: 7197892

Claim:
An encapsulated electrically driven compressor comprising: a hermetically sealed housing; a compressor device ( 20 ) for compressing refrigerant for a refrigerating cycle; an electric motor for driving the compressor device; a connecting device having electrically conductive terminal portions electrically connecting the electric motor to an electric control device which is located outside of the housing, and also having a terminal casing made of such material which is resistive against the refrigerant and oil and covering the electrically conductive terminal portions, wherein the compressor device, the electric motor and the connecting device are housed in the hermetically sealed housing, and wherein the terminal casing is air-tightly fixed to an inner wall of the housing, an opening having a small opening aperture is formed in the terminal casing at such a position which is lower than a position of the electrically conductive terminal portions in a vertical direction and is displaced by a predetermined distance towards an inside space of the housing, the opening is communicated with the inside space of the housing, and the opening aperture has a predetermined opening dimension.
