Abstract
A hybrid type compressor is provided that is drivable by an electric motor and an external driving source. The hybrid type compressor includes a housing and a compression mechanism. A shaft is rotatably supported by the housing for transmitting rotational driving force to the compression mechanism. The electric motor unit generates rotational driving force for rotating the shaft and includes a stator fixed to the housing and a rotor rotatable with respect to the stator. The hybrid type compressor also includes a pulley for receiving rotational driving force generated by the external driving source and for transmitting the rotational driving force to the shaft. Additionally, a one-way clutch is provided between the pulley and the shaft for allowing the rotational driving force generated by the external driving source to be transmitted only from the pulley to the shaft.
