Abstract

L'INVENTION CONCERNE UNE POMPE A LIQUIDES AVEC ENTREE INFERIEURE, SORTIE SUPERIEURE, DES MOYENS D'EMMAGASINAGE D'ENERGIE PRES DE L'ENTREE ET DES MOYENS DE PRESSION PRES DE LA SORTIE. LES MOYENS D'EMMAGASINAGE D'ENERGIE COMPRENNENT UNE PAROI ELASTIQUE AVEC MANCHON INTERIEUR POUR EN LIMITER LA RETRACTION. LES MOYENS DE PRESSION SONT UNE CHAMBRE DE PRESSION AVEC UN ANNEAU ELASTIQUE ET UNE PIECE CENTRALE MOBILE PAR RAPPORT A LA PAROI DE LACHAMBRE. L'ANNEAU EST ENGAGE SANS POUVOIR GLISSER, ENTRE LA PIECE CENTRALE ET LA PAROI. UNE SOUPAPE D'ECHAPPEMENT COMMANDE LA SORTIE ET RESTE FERMEE QUAND LA PIECE CENTRALE SE DEPLACE EN AUGMENTANT LA PRESSION DANS LA CHAMBRE. POMPE EMPLOYEE POUR ELEVER DU LIQUIDE D'UNE HAUTEUR SUPERIEURE A LA HAUTEUR BAROMETRIQUE.
