Abstract
An air control assembly for a fuel burner having a combustion chamber and a nozzle includes a control device which controls the amount of air that flows into the burner and an assembly dependent on fuel pressure which actuates the control device. A fuel inlet path is provided for communicating fuel to the nozzle and a fuel return path is provided for communicating excess fuel away from the nozzle. The assembly dependent on fuel pressure includes a piston and rod device adapted for reciprocation in a piston chamber. A nozzle block is provided in which the piston chamber is defined and the nozzle is supported.
