The present invention provides a gas burner (10) including: a distributor means (50) having at least one distribution chamber to distribute an air gas mixture around said distributor (50), said burner (10) including a plurality of flame ports (70) through which said gas mixture can pass and be ignited; at least one injector (39) associated with said distributor (50), said at least one injector (39) being positioned to inject gas into said at least distribution chamber via a venture formed of a vertically directed passage and transition port (64) and at least one venturi extension extending away from said transition port (64). The present invention also provides manifold for a gas burner (10), said manifold having an upper wall (12) and a lower wall (16) held in spaced apart relationship by a peripheral wall to define a cavity there between, said manifold including means (38) to mount at least one injector (39) so as to deliver an air gas supply to a distribution means (50) and an inlet port (18) to allow connection to a supply of gas, which can pressurise said cavity, said upper (12) and said lower (16) wall being formed from relatively thin sections.
L'invention concerne un brûleur à gaz (10) comprenant: distributeur (50) à au moins une chambre de distribution de mélange air/gaz autour du distributeur (50), avec une pluralité de pooints de falmme (70) laissant passer le mélange aux fins d'allumage ; au moins un injecteur (39) associé au distributeur (50) pour injecter du gaz dans la ou les chambres via un diffuseur à passage vertical et orifice de transition (64) et au moins une extension venturi depuis ledit orifice (64). L'invention concerne également un collecteur pour ce brûleur (10), avec une paroi supérieure (12) et une paroi inférieure (16) espacées par le biais d'une paroi périphérique pour définir une cavité entre les deux parois (12, 16), ledit collecteur comprenant un système (38) de montage d'au moins un injecteur (39) qui fournit un mélange air/gaz à un système de distribution (50) et un orifice d'accès (18) pour la connexion avec une alimentation de gaz, pouvant pressuriser la cavité, et les deux parois (12,16) ayant des sections relativement fines.
