Fuel burning control apparatus

A fuel control apparatus comprising a main hollow body having one end open to atmosphere and adapted to be connected at the other end to the intake manifold of an internal combustion engine;

• a hollow shaft mounted transversely in said hollow body with opposed marginal ends extending therefrom, a butterfly valve element mounted on said hollow shaft within said main body and arranged to that axial rotation of said shaft moves said butterfly valve element from a closed to an opened position, and vice versa, thereby controlling flow through said main hollow body;
• a marginal end of said hollow shaft being threaded, fuel flow ports drilled laterally into a medial part of said shaft in proximity of said butterfly valve, a valve seat formed within said hollow shaft between said threaded end and said fuel flow ports;
• a needle valve assembly having a valve element on one end, a fuel inlet end, a radial fuel port, and a threaded marginal area which threadedly engages the threaded end of said shaft while said valve element engages said seat to thereby preclude fuel flow when said shaft is rotated one direction, and progressively increases fuel flow therethrough when said shaft is rotated an opposite direction;
• a bracket affixed to said main body and extending therefrom and into engagement with said needle valve assembly;
• and means by which the needle valve assembly can be adjustably positioned respective to said bracket and seat so that the fuel flow through said seat is proportional to the flow of air across the butterfly valve.
