ABSTRACT:
A burner for a cooking grill has upper and lower sections which are joined together to enclose a plenum for containing a combustible gas. The lower section has a peripheral wall containing apertures which enable the gas in the plenum to escape for burning outside of the burner. In addition, the lower section has a bottom wall provided with a hole, while the top section has a top wall provided with a recess located opposite to the hole. A short inlet tube, to which the combustible gas is supplied, extends through the hole in the bottom wall, and within the plenum segments of the tube are bent outwardly away from the tube axis in the form of tabs which overlie the inwardly presented surface of the bottom wall. These segments leave the tube with openings that permit gas to flow from the tube to the plenum. The remaining tube segments of the inlet tube extend into the recess of the top section, so that the tube is captured firmly between the two burner sections, and these segments are presented toward the plenum apertures which are closest to the tube to prevent an excessive amount of gas from flowing to those apertures.
