ABSTRACT:
A fuel atomizing device for carburetors having a main discharge nozzle located within at least one venturi. The device comprises a hollow body extending downwardly and outwardly with a bottom opening adapted to slide over the main discharge nozzle in a sleeve-like arrangement. A fuel atomizing disc is supported concentrically by the body having top and bottom surfaces and an outer diameter atomizing edge. Four equally spaced apertures in the body below the disc are in flow communication with the body's bottom opening and, hence, the main discharge nozzle of the carburetor for evenly dispersing the fuel onto the bottom surface of the disc. A retaining cap is concentrically oriented on the body below the apertures for sealably seating the body upon the venturi. A threaded top opening in the body is adapted for receiving a set screw which permits movement of the screw by the apertures for constricting the apertures so that the atomizing device adjustably atomizes and disperses the fuel. Because of the air depression or vacuum in the vicinity of the venturi stack 14, the gasoline readily dispenses onto the bottom of the disc and is completely atomized as it is pulled off the outer diameter edge by action of the air flow downwardly through the carburetor which impinges upon the top surface of the disc creating a further vacuum under the atomizing disc.
