Fuel atomizing device and vaporizer

Claim 1

In combination with a carburetor supplying a mixture of liquid fuel and air to an intake manifold of an internal combustion engine, a fuel atomizing device comprising a conduit conducting the fuel-air mixture in one direction therethrough from the carburetor to the intake manifold and defining an atomizing zone intermediate the opposite ends of said conduit, said zone including a central longitudinal area bounded by an outer peripheral area extending about said central area and along said zone, and stationary flow deflecting means mounted within said central area and operative to impart lateral inward and outward oscillations to at least portions of the fuel and air in the mixture moving through said outer peripheral area at respectively different amplitudes in response to pressure differential induced flow of said mixture in said one direction, said flow deflecting means including a fixed central mounting stem, and a plurality of axially spaced generally flat discs secured to said stem defining low pressure pockets therebetween within the flow stream of said fuel-air mixture and disposed wholly within said central area.
