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.

Abstract: A carburetor for gasoline internal combustion engines includes a generally cylindrical housing having a mixing channel defined by a wall converging to a point of minimum housing diameter and a wall diverging from the point of minimum diameter, an intake air receiving section and a lower section from which the liquid fuel-air mixture is discharged to the cylinders. At least twelve radially spaced liquid fuel supply ports are formed in the mixing chamber immediately below the point of minimum opening. A regulating member formed generally of two frusto-conical sections arranged with their bases end-to-end is mounted for longitudinal movement within the housing. The upper section of the regulating member deflects the intake air toward a gradually enlarging constricted zone which is defined by the upper section of the regulating member and the diverging wall of the mixing chamber and wherein the liquid fuel is mixed with and atomized by the intake air.
