Abstract

Valve régulatrice de pression de sensibilité élevée et dotée d'un système d'amortissement La valve comprend un corps 12 dans lequel un tiroir 13 peut coulisser d'une position fermée à une position complètement ouverte en passant par une position intermédiaire, à l'encontre de l'action d'un ressort 23 qui porte contre une bague 19 du tiroir. Le ressort 23 est disposé dans une chambre qui communique avec un réservoir par un passage 27. Quand le tiroir s'écarte de sa position fermée, la bague tend à obturer le passage 27 et limite l'écoulement du fluide hors de la chambre, ce qui amortit fortement le déplacement du tiroir. Application notamment aux systèmes hydrauliques des tracteurs.
