Abstract

NOUVEAU SYSTEME OLEO-PNEUMATIQUE PERMETTANT LE REMPLISSAGE RAPIDE ET L'OBTENTION DE MOYENNES, HAUTES ET TRES HAUTES PRESSIONS DANS UN VERIN HYDRAULIQUE. IL COMPREND DANS UN CYLINDRE DONNE TROIS CHAMBRES INDEPENDANTES LES UNES DES AUTRES UNE CHAMBRE DE COMPRESSION D'HUILE. LES CHAMBRES SONT TRAVERSEES PAR DEUX ARBRES DONT L'UN EST FIXE, L'AUTRE MOBILE. A L'INTERIEUR DES CHAMBRES, 2 SONT EQUIPEES DE PISTONS LIBRES COULISSANT SUR L'ARBRE LES TRAVERSANT A TRAVERS LES PAROIS DU CYLINDRE. DANS LA TROISIEME CHAMBRE, LE PISTON EST SOLIDAIRE DE L'ARBRE ET CET ARBRE EST MOBILE, COULISSE SUR LES DEUX PORTEES DES PAROIS FIXES. SUR LES FONDS (COTE HAUTE PRESSION), L'ARBRE EST GUIDE ET TRAVERSE UN JOINT A LEVRES HAUTE PRESSION POUR COMPRIMER L'HUILE DANS LA CHAMBRE DE COMPRESSION D'HUILE. LES PISTONS LIBRES ACTIONNES PAR DE L'AIR COMPRIME, REMPLISSENT LE VERIN D'UNE VALEUR EGALE A SA CAPACITE. ENSUITE, LE PISTON SOLIDAIRE DE L'ARBRE LE FAIT PENETRER DANS LA CHAMBRE D'HUILE ET COMPRIME CELLE-CI EN RAPPORT AU DIAMETRE DU PISTON ET DE CELUI DE L'ARBRE. LES PRINCIPALES APPLICATIONS SERONT CELLES DE VERINS DE PRESSES HYDRAULIQUES POUR LES PLASTIQUES EN GENERAL.
