Abstract

L'invention concerne un système (50) de gonflage permettant de régler de manière indépendante le profil de pression, c'est-à-dire le temps de montée et le niveau plateau d'un fluide envoyé dans une chambre (18) gonflable par une source (56) de fluide, via des passages (52, 54) conduisant à des régulateurs (58, 60) haute et basse pression, et des réservoirs (62, 64) dont les sorties sont commandées par des soupapes (66, 68) permettant de produire les hautes et basses pressions requises à des moments spécifiques, afin de déterminer le profil de pression.
