Abstract

L'invention porte sur un ensemble pour limiter un excès de débit, lequel ensemble comprend un siège qui constitue une surface d'étanchéité et un diaphragme qui est accouplé au siège. Le diaphragme comprend une partie joint d'étanchéité et au moins une patte s'étendant entre la partie joint d'étanchéité et le siège. La partie joint d'étanchéité est espacée vis-à-vis de la surface d'étanchéité pendant des conditions d'écoulement normales, et est en prise avec la surface d'étanchéité quand une condition d'écoulement prédéfinie est dépassée.
