Abstract

Distributeur de gaz comportant une soupape principale reliant l'entrée à la sortie et actionnée dans le sens de fermeture par un ressort et dans le sens d'ouverture par une membrane, qui est sollicitée par la pression d'entrée lors de l'actionnement d'une valve d'enclenchement par l'intermédiaire d'une servo-buse. La buse il est branchée en parallèle à un dispositif 12-16 ayant un comportement différentiel. Application à l'amélioration de la sécurité dans la distribution des gaz.
