Abstract

POMPE CONFORME A LA REVENDICATION 3 DU BREVET PRINCIPAL, COMPORTANT UNE CHAMBRE ELASTIQUE IMMERGEE RELIEE A UN TUBE DE COMMANDE 6, REMPLI DE LIQUIDE EN POSITION DE SERVICE. LE PISTON DE COMMANDE 7 PRESENTE UN ALESAGE AXIAL 7A MONTE A COULISSE SUR UNE PARTIE CORRESPONDANTE 8B DE LA TIGE D'ACTIONNEMENT 8. UN JEU EST PREVU POUR ASSURER UNE FUITE ENTRE LA PARTIE 8B DE LA TIGE ET L'ALESAGE 7A DU PISTON 7. LA FUITE AINSI REALISEE FACILITE L'ECHAPPEMENT DE L'AIR EVENTUELLEMENT OCCLUS DANS LE CYLINDRE 6, QUI PEUT ETRE EVACUE PAR DES TROUS D'EJECTION 12 DE LA PAROI DU CYLINDRE 6. LA FUITE PERMET EGALEMENT UNE INJECTION D'EAU A TRAVERS LE PISTON 6, A CHAQUE COUP DE POMPE, POUR ASSURER REGULIEREMENT LA LUBRIFICATION DU CYLINDRE 6, DU PISTON 7, ET DE LA TIGE 8, AINSI QUE LEUR NETTOYAGE. APPLICATION AUX POMPES A CHAMBRE DEFORMABLE IMMERGEE, POUR AMELIORER L'ENDURANCE DE LEUR DISPOSITIF DE COMMANDE, EN PARTICULIER DANS LES PAYS EN VOIE DE DEVELOPPEMENT.
