ABSTRACT:
An improved viscous heater for a vehicle heating system is disclosed. The viscous heater has a heat generator including a rotor that agitates viscous fluid to generate the heat. A vehicle engine transmits its rotation to the rotor via an electromagnetic clutch. A thermosensitive switch is attached to the heat generator and selectively connects and disconnects the electromagnetic clutch with electric power source. The thermosensitive switch is selectively activated and deactivated based on magnitude of the heat generated by the agitated viscous fluid. The thermosensitive switch is deactivated when the ambient temperature is in excess of the predetermined uppermost value (T) and activated when the temperature in smaller than the predetermined lowermost value (T-.DELTA.T).
