    Abstract: 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.

    Abstract translation: 本公开涉及一种用于进行化油以提供用于操作内燃机等的空气和汽化燃料混合物的方法和装置。 蒸发和混合室恰好位于中间室上，中间室依次位于保持室上。 环境空气进入中间室，环境压力下的燃料进入容纳室。 提供了计量装置，用于计量从中间室进入蒸发和混合室的空气流并用于计量来自保持室的液体流。 燃料轴向流动到喷射口进入到与喷射孔相反的燃料流反向引导的多个空气喷射通道的汇合处，并将所得到的空气和液体燃料的混合物在柱中吸入蒸发和混合区。 向列中的空气 - 液体燃料混合物施加旋转运动，使得当其到达蒸发和混合塔时，其通过离心力而飞出到蒸发和混合室中。 空气喷嘴孔以尖锐的倾斜角度定向，使得喷射孔是在塔的底部的环形轨迹，并且燃料被喷射到轨迹的中心。 因此，在汇合处建立了湍流涡流，其促进燃料分解成微小的小球并将这些小球分散在空气中。
