Abstract

Soupape de commande utilisée dans des machines de travail pour commander hydrauliquement les mouvements de levage de la machine de travail telle qu'une machine rotative ou une charrue reliée à une machine motrice. On a représenté un carter de soupape de commande 1, une soupape d'inversion du type ayant la forme d'une bobine 2, une soupape de sûreté 3, un compensateur 4 et une soupape d'arrêt 5. Un cylindre A agit comme organe d'actionnement, ce cylindre A étant relié à un orifice C de cylindre prévu dans le carter 1 et l'actionnement étant effectué au moyen d'huile hydraulique fournie par la pompe P. Application aux machines agricoles.
