Abstract
a. Soupape avec un disque rotatif comportant un bord incliné coopérant avec un siège annulaire d'étanchéité. b. Caractérisée par un siège comprenant un corps et deux lèvres flexibles séparées orientées en sens inverses inclinées parallèlement au bord du disque, le corps et les lèvres étant séparés par une partie de col flexible flottante sous l'effet de la pression, l'amplitude du déplacement du col et des lèvres vers l'aval étant la même quel que soit le sens d'application de pression du fluide. c. Soupape équilibrée admettant les deux sens d'écoulement du fluide.
