Abstract

PURPOSE:To avoid to give load to an engine for acceleration by giving an electromagnetic clutch a separate state when either the car speed or the speed of engine revolutions is suddenly increased. CONSTITUTION:A voltage difference detector 14 is used to receive a DC voltage inversely proportional to the car speed or the speed of engine revolutions from a smoothing circuit 13 constantly for memorizing as an electric charge in a condenser C8. When the DC voltage output from the smoothing circuit 13 is suddenly reduced to give a minus voltage difference against the memorized voltage because of the sudden increase of the car speed or the speed of engine revolutions, the charge of the condenser C8 is discharged between the collector and the emitter of a transistor T1 to give output until the voltage difference is gone. This output is transmitted to a power circuit 15 to give an electromagnetic clutch 3 a separate state. Consequently, for acceleration, the load of the necessary power to drive a compressor in an air conditioner is prevented to be added to the engine.
