Abstract
CETTE POMPE COMPORTE UNE PLAQUETTE DE PRESSION 11 RIGIDE A LA FLEXION ET DONT LA SURFACE SOUMISE DANS L'ENCEINTE 15 A LA PRESSION P QUI Y REGNE EST PLUS GRANDE QUE SA SURFACE SOLLICITEE, DU COTE HAUTE PRESSION H DE LA POMPE, PAR LA PRESSION DU LIQUIDE VEHICULE. LA CONDUITE D'AMENEE DU LIQUIDE SOUS PRESSION A L'ENCEINTE 15 EST CONCUE SOUS FORME DE POTENTIOMETRE. EN PLUS DE LA BUSE 18 QUI CONDUIT AU COTE HAUTE PRESSION H DE LA POMPE EST PREVUE UNE DEUXIEME BUSE DONT LA SECTION D'ECOULEMENT EST PLUS PETITE ET QUI RELIE L'ENCEINTE 15 AU COTE BASSE PRESSION N DE LA POMPE.
