Abstract

Clapet anti-retour (10) comprenant un premier corps (14), disposé côté amont, et un deuxième corps (18) disposé côté aval et relié au premier corps (14). Un obturateur de clapet (20) est disposé de façon déplaçable dans une chambre de communication (42) formée à l'intérieur du premier corps (14). Un élément élastique (64), qui pousse par une force élastique l'obturateur de clapet (20) en appui contre le siège de clapet (46), est prévu sur l'obturateur de clapet (20). L'amenée d'un fluide sous pression au premier corps (14) a pour effet de déplacer l'obturateur de clapet (20) dans le sens opposé à la force élastique de la jupe (64). De ce fait, l'intérieur du premier corps (14) et l'intérieur du deuxième corps (18) sont mis en communication, et le fluide sous pression peut s'écouler à travers ces corps.
