Abstract
An automatic air-fuel ratio control apparatus for use in a combustion system of a type in which combustion air is preheated, which is so arranged that a push rod depresses one end portion of a rocking lever in accordance with temperature of preheated combustion air and consequently the other end portion of the rocking lever depresses a valve member to correct pressure of working fluid for controlling a flow of fuel so as to obtain best air-fuel ratio, and further that a bearing member for pivotally supporting the rocking lever can be diagonally shifted to change the air-fuel ratio.
