ABSTRACT:
In the preferred embodiment of the present invention, a pulse fog generator powered by a resonant intermittent combustion device having a carburetor and a combustion antechamber, includes a starting air supply system for directing a flow of starting air into the antechamber, comprising an inlet/outlet check valve mounted over the discharge opening of a bellows that is reciprocated by a connecting rod eccentrically mounted to an electric motor. A priming pump is mounted on the carburetor, and comprises a priming fuel chamber hydraulically communicating with the carburetor and a piston reciprocatable within the priming fuel chamber to draw fuel from a fuel tank into the priming fuel chamber and to discharge the fuel from the priming fuel chamber into the carburetor. An on-off control for the combustion device includes a shut-off plate, disposed over the air inlet of the carburetor, affixed to a slidably mounted plunger so that the shut-off plate can be moved between a position covering and a position displaced from the air inlet. The pulse fog generator has a pressure responsive formulation control apparatus inserted between a formulation tank and means for injecting formulation into the exhaust tube of the combustion device. The control apparatus includes a shut-off valve biased to a closed position restricting the flow of the formulation, and a diaphragm actuator including an engagement pin, extending from a pressure actuated diaphragm, adapted to engage the shut-off valve and hold the valve in an open position while the combustion device is operating.
