Abstract:
1. A gas burner with only an internal flame that converges toward a heat concentration point, comprising: a pot provided with an inlet for a mixture to be burned; a cap that sits on top of said pot, said pot and said cap defining a central zone for combustion of said mixture to be burned, and a peripheral chamber that extends around said central zone and communicates with said inlet; a plurality of passageways through which said mixture flows from said peripheral chamber toward said central zone; and a deflector that extends into at least a part of said peripheral chamber, said inlet opening into said peripheral chamber beneath said deflector, and said deflector being placed so as to separate said chamber into a lower subchamber, located approximately in an extension of said inlet, and into an upper subchamber adjacent said passageways, said deflector defining with a radially external wall of said peripheral chamber a passage between said lower subchamber and said upper subchamber, said deflector being configured such that said mixture to be burned flows into said lower subchamber, fills said lower subchamber, flows through said passage, flows through said upper subchamber, flows through said passageways, and flows into said central zone.
