Abstract

LE DISPOSITIF SELON L'INVENTION EST UN SYSTEME DE POMPAGE DE LIQUIDES A PRESSION DE GAZ, CARACTERISE EN CE QU'IL COMPORTE AU MOINS DEUX RESERVOIRS PRESSURISES, DONT L'UN MAINTIENT LE DEBIT DANS L'UTILISATION PENDANT QUE L'AUTRE SE REMPLIT DU LIQUIDE CONTENU DANS UN RESERVOIR PRINCIPAL, LEQUEL EST PRESSURISE OU EN CHARGE. LE REMPLISSAGE S'EFFECTUANT DANS CE DERNIER CAS PAR GRAVITE. LA FIGURE I MONTRE LE FONCTIONNEMENT GENERAL DE CETTE POMPE: UN GAZ SOUS PRESSION 1 POUSSE LE LIQUIDE CONTENU DANS LES RESERVOIRS PRESSURISES 3 ET 4 VERS L'UTILISATION 6. LORSQUE LE NIVEAU ATTEINT LE DETECTEUR 8, LA VANNE 5 MET LE RESERVOIR 4 A LA PRESSION ATMOSPHERIQUE, LE CLAPET 9 OU VANNE SE FERME, LE 10 S'OUVRE ET LE RESERVOIR 2 REMPLIT LE 4, JUSQU'AU NIVEAU DU DETECTEUR 12 QUI COMMUTE LA VANNE 5. LA PRESSION EST ALORS A NOUVEAU ADMISE DANS LE RESERVOIR 4 QUI, APRES COMMUTATION DES CLAPETS OU VANNES 9 ET 10 POUSSE LE LIQUIDE VERS L'UTILISATION TOUT EN REMPLISSANT PAR EFFET DE VASES COMMUNIQUANTS LE 3 PUIS LE CYCLE RECOMMENCE. PENDANT TOUT CE CYCLE, LE DEBIT N'A PAS ETE AFFECTE.
