Abstract
In a hybrid type compressor, a one-way clutch is provided between a magnet rotor and a rotor shaft for allowing rotational driving force generated by an electric motor unit to be transmitted only from a rotor to a shaft. Thus, the rotational driving force generated by a vehicle engine is not transmitted from the rotor shaft to the magnet rotor. That is, an inertia moment of a rotational system with respect to a vehicle engine is made small, thereby reducing the impact vibration when the clutch mechanism engages.
Claims11
A hybrid type compressor driven by an electric motor and an external driving source, 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 moving with respect to said fixed member;
- a shaft rotatably supported in 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 rotating within said stator;
- a clutch mechanism for transmitting rotational driving force of said external driving source to said shaft;
- and
- a one-way clutch for allowing the rotational driving force generated by said electric motor unit to be transmitted only from said rotor to said shaft.
