Abstract

L'invention concerne un ensemble diffuseur (10) comprenant des premier et second corps diffuseur (23, 24) en communication fluidique avec un tuyau de distribution d'air (14). Ledit ensemble diffuseur (10) comporte également une sellette (16) qui supporte les premier et second corps diffuseurs (23, 24). La sellette (16) est reliée au tuyau de distribution (14) par un rivet à noyau creux (90). Le fluide est poussé de force du tuyau de distribution (14) dans le rivet à noyau creux (90) au niveau duquel il traverse les premier et second diffuseurs (23, 24). Le fluide sort du premier corps diffuseur (23) à travers un premier milieu de diffusion (35) et sort du second corps diffuseur (24) à travers un second milieu de diffusion (36). Les premier et second milieux de diffusion (35, 36) transforment l'air en petites bulles qui facilitent l'aération du fluide.
