Abstract

LE DISPOSITIF EST DESTINE A MODULER LE FLUX D'ENTREE DE FLUIDE VERS L'UNE DES DEUX CHAMBRES 180, 182, CHOISIES D'UN ENSEMBLE MOBILE 160, 162 SOUMIS A DES FORCES. UN CONTROLEUR 40 EST COUPLE ELECTRIQUEMENT A UN PREMIER 20 ET UN SECOND 22 ENSEMBLE A VALVE PILOTE ACTIONNE PAR SOLENOIDE POUR: 1MAINTENIR L'ENSEMBLE A VALVE PILOTE 20, 22 DANS UN ETAT DE FERMETURE SANS PRELEVER DE FLUX PAR LES ORIFICES 32, 34; OU 2ENVOYER UN SIGNAL ELECTRIQUE DE VALEUR PREDETERMINEE A L'UN DES DEUX ENSEMBLES A VALVES 20, 22 POUR ACTIONNER L'UN DES ENSEMBLES EN RELATION AVEC LA VALEUR DU SIGNAL. LE FLUIDE EST APPLIQUE SOUS LES CLAPETS 24, 26 DES DEUX ENSEMBLES A VALVE 20, 22. LE FLUX DE FLUIDE EST PRELEVE EN 42, 43 A PARTIR DU DESSUS DU CLAPET D'UN ENSEMBLE A VALVE COMMANDEE VERS UNE CHAMBRE RESPECTIVE 44, 48 GRACE A QUOI L'ENSEMBLE MOBILE 49 SE DEPLACE VERS UNE POSITION QUI EST UNE FONCTION DE LA VALEUR DU SIGNAL D'ACTIONNEMENT.
