Abstract

L'invention concerne une pompe à fluide qui comprend un élément séparateur mû par des moyens de déplacement alternatif qui délimite, par un de ses côtés et un corps latéral ou distributeur (22a) de Ia pompe, une chambre de fluide (11a) conçue pour contenir un fluide à déplacer et au moins deux vannes (12a, 12b) fonctionnellement connectées à ladite chambre de fluide (11a) pour établir une communication fluidique avec cette dernière; lesdites vannes (12a, 12b), au moins au nombre de deux, étant du type entrée-sortie, et étant commandées pour fournir un flux sélectif bidirectionnel. L'élément séparateur de type membrane ou piston et les vannes (12a, 12b) sont associés à un système de commande (18) conçu pour faire circuler ledit fluide dans la chambre de fluide (11a) dans un sens désiré.
