Abstract
Soupape de sécurité agissant en réponse aux surpressions et aux dépressions. La chambre 24 étant reliée au vérin 12 et celle 26 à la bâche 28, en cas de pression excessive le clapet 54-58 décolle du siège 44 à l'encontre du ressort 74 en permettant à l'huile de revenir à 28. En cas de dépression, c'est l'élément creux 32 qui se sépare du siège 84 à l'encontre du ressort 70 en permettant une rentrée d'huile. Application aux commandes par vérins hydrauliques ou similaires pour éviter toute rupture et tout risque de cavitation.
