ABSTRACT:
An air control regulator regulates the amount of air flowing into the inlet of a combustion chamber by causing flowing air to support a disc located in the air passage against the force of gravity. Air passes around the edges of the disc and is channeled into a plurality of airflows by ovoid depressions in the inner surfaces of the regulator forming a venturi chamber. By regulating the airflow into the combustion chamber, combustion efficiency is improved.
