摘要： Burner Tubes for Gas Grills are disclosed. An example burner tube includes a linear burner tube including a venturi member disposed within a hollow interior of the linear burner tube proximate an open front end of the linear burner tube. The venturi member includes a front face having an opening configured to receive a neck of a gas valve, an upper flange extending rearwardly from an upper edge of the front face, the upper flange having a downwardly-extending V-shaped segment configured to constrict a region of the hollow interior, and a lower flange extending rearwardly from a lower edge of the front face, the lower flange having an upwardly-extending V-shaped segment configured to further constrict the region of the hollow interior.

摘要： Burner tubes for gas grills are disclosed. An example burner tube includes an open front end, a closed rear end located opposite the open front end, opposing upper and lower surfaces extending between the open front end and the closed rear end, opposing right and left side surfaces extending between the upper surface and the lower surface and between the open front end and the closed rear end, and a hollow interior defined by the upper surface, the lower surface, the right side surface, and the left side surface. The hollow interior has a rectangular cross-sectional profile that tapers in a direction moving from the open front end toward the closed rear end. The burner tube further includes a plurality of gas ports extending upwardly from the upper surface, with each one of the gas ports having an exit opening raised above the upper surface.
