    Abstract: An apparatus for supplying positively controlled amounts of an atomized and vaporized liquid fuel and air for combustion in an internal combustion engine, said apparatus comprising an energizable sonic probe, having a vibratory fuel atomizing surface at one end, and a conduit including a variable volume chamber and a main metering valve for distributing controlled amounts of fuel to a means for directing a thin film of fuel across the atomizing surface. The sonic vibrational energy of the sonic probe performs work on the film as it migrates across the atomizing surface, causing the fuel to atomize and vaporize. The atomizing surface is exposed to a flow of air moving towards the engine, and the atomized fuel is effectively mixed with the air to form a highly suitable fuel-air mixture for efficient combustion in the engine. A throttle valve controls the flow of air through the passageway. The main fuel metering valve and a means for varying the volume of the variable volume chamber positively control the amount of fuel supplied in relation to the amount of air supplied through the throttle valve. In a preferred embodiment, a bypass fuel valve responsive to intake manifold pressure prevents stalling at idle throttle setting and enriches the mixture under load conditions.
