Abstract

Pompe pour la délivrance d'un fluide contenu dans un flacon élastique, comprenant: - un corps de pompe ayant une extrémité antérieure du côté de la sortie du fluide, ladite extrémité antérieure comportant un orifice de sortie (11) obturé par une membrane élastique (24), et se poursuivant vers l'arrière par un conduit de pompe (18) muni d'un orifice (15) d'admission de fluide, - un piston mobile installé dans le corps de pompe, le déplacement relatif de l'extrémité (2) du piston par rapport au corps de pompe entre l'orifice (15) d'admis-sion et une position en butée (16) située vers l'orifice de sortie (11) déterminant ainsi la quantité de fluide expulsée lors du déplacement, l'extrémité (2) du piston étant ajustée hermétiquement à frottement doux au conduit de pompe (18), l'orifice d'admission (15) étant de taille suffisante pour que seule la quantité de fluideprédéterminée puisse se trouver capturée dans l'extrémité du conduit de pompe (18) en vue de son expulsion par l'orifice de sortie (11), le corps de pompe et le piston étant totalement enveloppés par le flacon, à l'exception de l'extrémité antérieure du corps de la pompe.
