ABSTRACT:
A device for carburetting air and fuel includes, a housing having its wall confining a main air passage of converging-diverging shape, an annular chamber around the diverging portion of the passage, a plurality of tubes for sucking the fuel from the annular chamber and spraying it at the throat portion of the passage. The walls of the tubes are respectively provided with a plurality of openings which are communicated with pilot air inlet passages branching off the main air passage. The on and off positions of the openings are controlled by an automatic pressure sensitive system so as to adjust the fuel-to-air ratio of the fuel feed. A throttle valve is provided at the throat portion for controlling the rate of the fuel-air mixture flow.
