Abstract

Un élément à volume expansible (11) comprend un sac dégonflé (15), une source (21), (22) d'un agent de gonflage et un dispositif (20) pouvant être actionné de façon à permettre l'introduction de l'agent de gonflage dans le sac en vue de son gonflement. L'agent de gonflage se transforme en une masse solide lorsqu'il se trouve dans le sac gonflé. Ladite masse solide peut être utilisée pour boucher hermétiquement un passage et les applications décrites sont notamment celles qui utilisent l'élément décrit comme flotteur pour un bateau qui coule (13) ou pour un avion s'étant écrasé en mer.
