Abstract

Soupape sensible à la pression, comprenant un cylindre raccordé à une extrémité à une source de pression et dans lequel peut coulisser un piston, maintenu à une position prédéterminée par un enclenchement. Le dispositif d'enclenchement comprend au moins un élément d'enclenchement porté par le piston et qui peut pénétrer en partie dans un logement du cylindre. Un élément de rappel, mobile longitudinalement dans le piston, pousse l'élément d'enclenchement vers le logement Des moyens de rappel tendent à déplacer longitudinalement l'élément de rappel dans le sens de poussée de l'élément d'enclenchement vers le logement. La soupape suivant l'invention s'applique à des circuits hydrauliques qu'elle protège contre les surpressions et dont elle signale les défauts de fonctionnement.
