Abstract

L'invention concerne un procédé de gonflage d'une chambre à air selon le brevet principal. On gonfle lentement la chambre à air primaire et la chambre à air secondaire jusqu'à une pression inférieure à la pression finale de consigne de la chambre primaire, puis on augmente brusquement la pression à l'entrée de la valve de gonflage de la chambre à air pour provoquer la fermeture des valves spéciales reliant les deux chambres à air primaire et secondaire; on poursuit le gonflage de la chambre primaire jusqu'à la pression finale précitée. Le dispositif correspondant comporte deux sections intermédiaires de passage d'air disposées en parallèle, 12b à forte perte de charge, et à faible perte de charge. L'invention permet de remédier à la porosité ou aux perforations de la chambre à air secondaire.
