ABSTRACT:
A primary fuel-air mixture is dispersed into an airstream flowing through a venturi to achieve a desired final fuel-air mixture. The flow of air through the venturi is operatively controlled by a throttle valve means which includes a tube member having a fuel dispersing end positioned generally within a constricted portion of the venturi. Movement of the throttle tube selectively positions the fuel dispersing end in a spaced apart relationship with the constructed portion of the venturi and regulates the quantity of fuel and air flowing into an engine. The primary fuel-air mixture is supplied to a hollow interior portion of the throttle tube, and is dispersed uniformly from the fuel dispersing end of the throttle tube into the airstream. The quantity of primary fuel-air mixture dispersed is related to the quantity of air flowing through the venturi. The throttle tube is also selectively positionable to seal the fuel dispersing end with the constricted portion of the venturi, and under such circumstances a supply of idle fuel and air mixture is dispersed from the hollow interior of the throttle tube member.
