Abstract

Cet appareil comprend un distributeur commutateur piloté 12 et une soupape de blocage 15 montée dans le courant de fluide de pression envoyé vers l'utilisateur (releveur) 11 et combinée avec un piston de déblocage 16. La soupape 15 a la double fonction d'une soupape antiretour et d'une soupape d'abaissement et le piston de déblocage 16 a en plus une fonction directionnelle. L'appareil est ainsi rendu moins coûteux, plus étanche et plus sûr dans son fonctionnement. Il est applicable en particulier comme valve de réglage à commande électromagnétique pour des outils mûs hydrauliquement sur des véhicules agricoles.
