摘要： The disclosure relates to a process and apparatus for effecting carburetion to provide an air and vaporized fuel mixture for operating an internal combustion engine, or the like. A vaporizing and mixing chamber is justaposed on an intermediate chamber which, in turn, is justaposed on a holding chamber. Ambient air is admitted to the intermediate chamber and fuel at ambient pressure is admitted to the holding chamber. Metering means is provided for metering air flow from the intermediate chamber into the vaporizing and mixing chamber and for metering the flow of liquid from the holding chamber. The fuel flows axially to a jet orifice into the confluence of a plurality of air jet passages directed counter to the flow of fuel to the jet orifice and the resultant mixture of air and liquid fuel is aspirated in a column into the vaporizing and mixing zone. A whirling motion is imparted to the air-liquid fuel mixture in the column so that, when it reaches the vaporizing and mixing column, it flies out by centrifugal force into the vaporizing and mixing chamber. The air jet orifices are directed at an acute, oblique angle, so that the jet orifices are an annular loci at the base of the column and the fuel is jetted up into the center of the loci. A turbulent vortex is thus established at the confluence which promotes disintegration of the fuel into tiny globules and dispersion of these globules into the air.
