Abstract
A burner assembly includes a burner housing having a combustion chamber defined therein and a fuel injection nozzle secured to the burner housing and communicating with the combustion chamber. A fuel control device is provided for controlling the amount of fuel flowing through the nozzle. The fuel control device includes a valve chamber including a bore and a valve seat and a needle valve adapted to reciprocate in the valve chamber. An adjusting device is provided for adjusting a range of motion of the needle valve in the valve chamber. The adjusting device includes a control rod secured at one end to the needle valve and a bimetallic assembly for regulating the motion of the control rod. The bimetallic assembly includes a pair of legs which are operably connected to the control rod and are exposed to the heat produced by the burner assembly.
