ABSTRACT:
A refrigerant compressor for use in an automotive air conditioning refrigerating system is provided with an electromagnetic clutch and an AC electric generator assembled on the compressor. The electromagnetic clutch comprises a pulley rotatably mounted on the compressor housing to be driven by the engine of the car, a magnetic attracting surface, and a magnetic armature connected to a drive shaft of the compressor to be magnetically attracted to the magnetic attracting surface to selectively drive the compressor by the engine. The AC electric generator comprises a stator statically mounted on the compressor housing and a rotor mounted on the pulley. One of the stator and the rotor includes concentric magnetic pole pieces of permanent magnets or of electromagnets, and the other of the stator and rotor includes a coil member to which AC current is induced upon the rotation of the rotor together with the pulley. Electric power is obtained from the AC electric generator to compensate for the power consumption of the car battery in the use of the air conditioning refrigerating system.
