PURPOSE:To flow a fuel supplied from a nozzle pipe through a path under an uniform distribution by a method wherein a velocity component in the direction of the nozzle pipe at the injecting section of the fuel is reduced and the flow of the fuel in the path of the Venturi is rendered to rely upon the airflow in said path. CONSTITUTION:When the air flows through the Venturi path 4 and a vacuum is generated, the fuel is entered into an annular fuel path 6 through the path 2 and is flowed under opposing to the fuel injecting section 9 from respective intersecting points B2, B3 thereby losing the velocity component in the direction of the nozzle pipe 8. Accordingly, the fuel is supplied to the Venturi path 4 uniformly or radially about the center line C relying upon the airflow flowed through the venturi path 4. Here, in case the airflow is small and the fuel is not being atomized, it may be atomized by inflow air from an air port 10. Thus, troubles such as the irregular rotation of engine or the like may be eliminated. |
