Title
(EN) PUMP FOR MEASURING OUT A FLUID
(FR) POMPE POUR DOSER UN FLUIDE
Abstract
(EN)
A pump for measuring out a fluid comprises a first and a second pumping chamber, which comprise an inlet valve and an outlet valve, respectively, moving between an opened configuration and a closed configuration; the pump further comprises a transfer valve interposed between the first and second pumping chambers and being movable between an opened configuration and a closed configuration for respectively permitting or preventing the flow of a fluid, an comprises as well an actuator group configured to mediate the passage of each valve from the closed configuration to the opened configuration and promotes a pumping of the fluid from the first to the second pumping chamber.
(FR)
Cette invention concerne une pompe pour doser un fluide, comprenant une première et une seconde chambre de pompage, qui comprennent une soupape d'admission et une soupape de sortie, respectivement, se déplaçant entre une configuration ouverte et une configuration fermée. La pompe comprend en outre une soupape de transfert interposée entre les première et seconde chambres de pompage et mobile entre une configuration ouverte et une configuration fermée pour permettre ou empêcher respectivement l'écoulement d'un fluide, ainsi qu'un groupe d'actionneurs configuré pour intervenir dans le passage de chaque soupape de la configuration fermée à la configuration ouverte et favoriser un pompage du fluide de la première à la seconde chambre de pompage.
