Abstract

L'INVENTION CONCERNE UN ENSEMBLE MODULATEUR AVEC VALVE ET COMPENSATEUR A DEUX ETAGES POUR MODULER L'ECOULEMENT DE FLUIDE. UN CLAPET DE PREMIER ETAGE 23 SE DEPLACE ENTRE UN ETAT NORMALEMENT FERME ET UN ETAT OUVERT POUR COMMANDER L'ECOULEMENT DE FLUIDE A TRAVERS LE SECOND ETAGE 25, 35. UN CLAPET DE SECOND ETAGE 25 SE DEPLACE ENTRE UN ETAT OUVERT ET UN ETAT FERME LORSQUE LE CLAPET DE PREMIER ETAGE 23 EST DANS L'ETAT NORMALEMENT FERME POUR EVITER TOUT ECOULEMENT SUBSTANTIEL DE FLUIDE A TRAVERS LES PREMIER ET SECOND CLAPETS. UN SIGNAL ELECTRIQUE DE VALEUR PREDETERMINE EST APPLIQUE A UN MOYEN ELECTROMAGNETIQUE 40 POUR DEPLACER LE CLAPET DE PREMIER ETAGE 23 EN POSITION OUVERTE EN RELATION AVEC LA VALEUR DU SIGNAL ELECTRIQUE. DE CETTE MANIERE, LE CLAPET DE SECOND ETAGE 25 SE DEPLACE AUSSI A UNE POSITION QUI DEPEND DE CE SIGNAL.
