ABSTRACT:
A variable venturi carburetor comprised of an open carburetor body enclosing an interior first venturi member and coaxial peripheral second venturi member. The second venturi member is integral with the carburetor body and defines a peripheral annular fuel dispensing orifice. The first venturi member is movable relative to the second venturi member along an upright axis. The venturi members together define an annular restricted air passage adjacent the fuel dispensing orifice that may be varied in size to increase or decrease the volume and velocity of air passing by the orifice. Fuel is supplied from an annular fuel chamber to the orifice in response to movement of air thereby. Various air bleed provisions are made to insure proper air-fuel mixing throughout the entire operational range of the engine on which the carburetor is attached. Provisions are also made to bleed air into the fuel supply as it is being delivered to the mixing chamber in order to premix a charge of air and fuel before it enters the carburetor mixing chamber.
