Patent ID: 6874328

Claim:
A hybrid compressor device comprising: a driving unit rotated by receiving driving force from an outside driving source; a motor rotated by receiving electric power from an outside power source; a compressor operated by at least one of the driving unit and the motor, the compressor being for compressing refrigerant in a refrigerant cycle system, the compressor including a suction area into which refrigerant before being compressed is introduced, a discharge area into which compressed refrigerant flows, and an oil separating unit for separating lubrication oil contained in refrigerant from the refrigerant and for storing the separated lubrication oil in the discharge area; a transmission mechanism disposed between the compressor and at least any one of the driving unit and the motor, the transmission mechanism being for changing a rotational speed of the at least one of the driving unit and the motor, to be transmitted to the compressor; a housing for accommodating therein the motor and the transmission mechanism; and means for forming an oil introducing passage through which the lubrication oil stored in the discharge area is introduced into the housing, wherein an inner space of the housing communicates with the suction area through a communication passage.
