Abstract
Gas burner (1) for oven, or grill, of the type comprising a Venturi tube (2) for mixing fuel gas and primary air, a main distribution chamber (3), longitudinally extended in the flow forwarding direction of the mixture, and located downstream to such a Venturi tube (2), as well as at least one delivery chamber (22a, 22b) placed outside the afore said main chamber (3), and provided with flame holes (4; 4a, 4b, 4c, 4d) for the gas-primary air mixture outflow, such a main chamber (3) and such an outer chamber (22a, 22b) being reciprocally fluidically connected, for at least one longitudinal length of the same main chamber (3), by at least one through opening (16a, 16b, 17a, 17b). Advantageously, the afore said through opening (16a, 16b, 17a, 17b) has, relative to the forwarding longitudinal direction of the mixture flow, a greater cross section in the upstream portion and smaller cross section in the downstream portion of the afore said longitudinal length of the main chamber (3).
