ABSTRACT:
Gas burner, particularly for household appliances, comprising a burner body (1) having a peripheral side wall (5) defining an enclosure with an outward opening and at least one air-gas mixture supply orifice (13), which enclosure is adapted to contain a "soft" flame able to withstand sudden pressure variations of the primary air brought to the burner and to re-activate the flames of the burner should they be blown out, characterized in that it further comprises at least one chamber (15) situated behind the supply orifice (13) of said enclosure (11) and itself having a gas mixture supply orifice (16) with a cross section substantially equal to or greater than that of the supply orifice (13) of the enclosure, this chamber being configured so that the air-gas mixture which is contained therein forms a buffer cancelling out or attenuating the sudden pressure variations of the primary air admitted into the burner and so that the flame of the enclosure is maintained.
