Lance pour extincteur et extincteur comprenant une telle lance Une lance (18) pour extincteur est destinée à la projection et au moussage d’un agent extincteur sans fluor. La lance définit un conduit d’écoulement (22) et comprend, dans le sens de l’écoulement : - une buse d’injection (28) comprenant au moins deux trous d’injection, - au moins une ouverture d’entrée d’air (30) reliant l’extérieur de la lance au conduit d’écoulement, destinée à aspirer de l’air depuis l’extérieur de la lance vers l’intérieur du conduit d’écoulement, de sorte à permettre le moussage de l’agent extincteur par mélange avec l’air, - un tamis de moussage (34), destiné à améliorer le moussage de l’agent extincteur, - un éclateur aval (36), destiné à diviser l’écoulement de l’agent extincteur en plusieurs jets distincts. Pour améliorer le moussage de l’agent extincteur, l’éclateur aval comprend au moins trois branches et la lance comprend en outre un éclateur amont (32), situé entre l’ouverture d’entrée d’air et le tamis de moussage.
