Abstract

L'INVENTION CONCERNE UNE POMPE POUR DOSAGES ETOU DILUTIONS A REGULATION DES DEBITS UNITAIRES, COMPRENANT UNE CHAMBRE RELIEE A UN CONDUIT COMPRENANT EVENTUELLEMENT UNE SOUPAPE D'ASPIRATION ET A UN CONDUIT DE REFOULEMENT, COMPRENANT EVENTUELLEMENT UNE AUTRE SOUPAPE, AINSI QU'UN PISTON PENETRANT EN COULISSANT DANS LA CHAMBRE ET COMMANDE AVEC DES COURSES REGLABLES DE FACON CONTINUE OU DISCONTINUE. LA POMPE SELON L'INVENTION EST CARACTERISEE EN CE QUE LE PISTON - CONCU COMME UNE TIGE DE SECTION CIRCULAIRE - PASSE A TRAVERS DEUX PAROIS OPPOSEES DE LA CHAMBRE ET PRESENTE DEUX DIAMETRES LEGEREMENT DIFFERENTS DANS LES TRONCONS QUI TRAVERSENT LES PAROIS, CE QUI FAIT QUE LA VARIATION DU DEBIT EST MODESTE, MEME AVEC UNE VARIATION APPRECIABLE DE LA COURSE ET AVEC DES DIMENSIONS NOTABLES DU PISTON A TIGE, ALORS QUE LES TRAVAUX MECANIQUES SUR LES DEUX DIAMETRES SONT FACILES ET PRECIS. APPLICATION A LA FABRICATION DES POMPES.THE INVENTION CONCERNS A PUMP FOR DOSAGE AND OR DILUTIONS WITH UNIT FLOW REGULATION, INCLUDING A CHAMBER CONNECTED TO A DUCT INCLUDING A SUCTION VALVE AND A DISCHARGE DUCT, POSSIBLY INCLUDING ANOTHER VALVE, AS WELL AS PISTON. SLIDING INTO THE BEDROOM AND CONTROLS WITH ADJUSTABLE RUNS OF CONTINUOUS OR DISCONTINUOUS WAY. THE PUMP ACCORDING TO THE INVENTION IS CHARACTERIZED IN THAT THE PISTON - DESIGNED AS A ROD WITH A CIRCULAR SECTION - PASSES THROUGH TWO OPPOSED WALLS OF THE CHAMBER AND HAS TWO SLIGHTLY DIFFERENT DIAMETERS IN THE TRUNCONS THAT CROSS THE WALLS, WHICH DOES VARIATION IN FLOW RATE IS MODEST, EVEN WITH APPRECIABLE VARIATION IN STROKE AND WITH NOTABLE DIMENSIONS OF THE ROD PISTON, WHILE MECHANICAL WORK ON BOTH DIAMETERS IS EASY AND PRECISE. APPLICATION TO THE MANUFACTURE OF PUMPS.
