Abstract
L'invention concerne un dispositif qui permet de générer de la mousse destinée à la lutte contre l'incendie. Le dispositif comprend deux plaques (50, 60) disposées dans une chambre (10), dont l'une amène de l'air comprimé et l'autre une solution, constituée d'eau et d'un tensioactif, dans l'espace qui les sépare. La mousse est générée dans ledit espace, puis évacuée par une ouverture (40) formée sur un côté de la chambre (10). La solution eau/savon sous pression entre dans la chambre par un orifice (52) formé dans l'une des plaques (50). L'air comprimé entre dans la chambre (10) par un certain nombre de canaux (64), formés dans l'autre plaque (60), qui débouchent dans une rainure annulaire (63) entourant l'orifice d'eau (52). La zone rétrécie (70) répartit la pression entre l'eau et l'air entrants en créant un équilibre à une distance du centre des deux plaques (50, 60) égale à un certain rayon. Le dispositif comprend également un système régulateur de pression (182), qui coupe automatiquement l'arrivée d'eau et d'air sous pression quand la busette (174) distributrice de mousse est fermée.
