L'air et le fluide pouvant mousser sont transformés en mousse au moyen d'une chambre de moussage (4). Pour que le moussage du distributeur doseur soit particulièrement efficace et qu'il puisse être influencé de manière ciblée et utilisé pour les fluides pouvant mousser les plus divers, il est prévu dans la chambre de moussage des traverses d'écoulement (16) qui s'étendent à l'intérieur de la chambre de moussage et s'engrènent les unes dans les autres sous la forme d'un labyrinthe d'écoulement, formant un canal de moussage (17).
