Beschreibung
Zusammenfassung:	The inflatable membrane apparatus (10) comprises: - a fluid accumulator (11) having an upper and a lower face and a fluid entrance (12), said lower face being partly formed by an inflatable membrane (14), and - a trunconical part (15) projecting outwardly from the lower face of the accumulator whose greater base is closed by at least part of the inflatable membrane (14) and smaller base forms a circular opening, whereby, when pressurized fluid is introduced into the accumulator (11), deformation of the inflatable membrane (14) is guided by the trunconical part. L'appareil à membrane gonflable (10) comprend un accumulateur de fluide (11) possédant une face supérieure et inférieure et une entrée pour le fluide (12), ladite face inférieure est partiellement formée par une membrane gonflable (14), et une partie tronconique (15) faisant saillie vers l'extérieur à partir de la face inférieure de l'accumulateur dont la base la plus grande est fermée par au moins une partie de la membrane (14) et la base la plus petite forme une ouverture circulaire, par laquelle, le fluide pressurisé est introduit dans l'accumulateur (11). La déformation de la membrane gonflable (14) est guidée par la partie tronconique.
