Abstract
Dispositif de commande pour outillages hydrauliques, servant de soupape de régulation à commande électromagnétique dans les tracteurs agricoles. Le dispositif 10 commande un releveur hydraulique 11. Il se compose essentiellement d'une soupape d'inversion 12 dont le tiroir 13 possède un tiroir de contrôle 14, d'une soupape d'arrêt 15 branchée dans le courant du fluide vers le releveur 11 et faisant office de soupape antiretour et de soupape d'abaissement, d'un piston de déblocage 16 et de deux soupapes pilotes 17 et 18.
