ABSTRACT:
A carburetor for gasoline internal combustion engines includes a generally cylindrical housing having an intake air receiving section. A fuel atomization and distribution device is mounted in the housing immediately below the intake air receiving section. It comprises an upper ring-like insert having twelve equally spaced openings extending through the ring to form auxiliary air bleeds for the carburetor. Mounted beneath the upper insert is a second ring-like insert comprising a generally annular outside wall, a conically-shaped interior wall and a generally annular top wall. The outside wall includes a tapered section that forms the fuel distribution channel for the carburetor. Twelve generally rectangularly shaped fuel supply channels are formed in the top wall of the insert in alignment with the openings formed in the first insert and in communication with the tapered section.
Within the carburetor a regulating member is mounted for longitudinal movement. It is in the configuraion of two generally frusto-conical sections with the bases of the two sections arranged end-to-end. The upper section has a taper angle which is the same as the angle of divergence of the inside wall of the lower insert and forms therewith a constricted zone wherein atomization of the liquid fuel takes place. The lower section of the regulating member provides, together with the interior wall of the housing, an expansion area through which the atomized liquid fuel-air mixture passes before being supplied to the engine manifold.
Finally, a variable air bleed device supplies a variable amount of air to the fuel supply passage that communicates with the fuel distribution channel formed in the second insert. The variable air bleed device causes the initial atomization of the liquid fuel before the fuel is supplied to the fuel distribution channel.
