Abstract

Vanne réductrice de pression, du type ''pilote'', comportant une vanne-pilote (11) combinée à la vanne principale (5), afin de commander la vanne principale (5) en réponse aux variations de la pression du fluide du coté primaire de la vanne principale, afin de régler la pression secondaire. Chaque vanne est associée à un plongeur ayant un cylindre et un piston inséré avec glissement dans celui-ci et on a réalisé une amélioration du dispositif d'étanchéité entre le piston et le cylindre.
