Abstract:
A hybrid type compressor drivable by an electric motor and an external driving source, said hybrid type compressor comprising:a housing; a compression mechanism provided in said housing for suctioning and compressing a fluid, said compression mechanism including a fixed member fixed to said housing and a movable member movable with respect to said fixed member; a shaft rotatably supported by said housing for transmitting rotational driving force to said movable member; an electric motor unit for generating rotational driving force for rotating said shaft, said electric motor unit including a stator fixed to said housing and a rotor rotatable with respect to said stator; a pulley for receiving rotational driving force generated by said external driving source and for transmitting the rotational driving force to said shaft; a one-way clutch provided between said pulley and said shaft for allowing the rotational driving force generated by said external driving source to be transmitted only from said pulley to said shaft; and a variable capacity mechanism capable of varying an amount of said fluid discharged from said hybrid type compressor.
