Abstract
(EN)
A membrane (1) for use in a pumping device, the membrane (1) having an elongated flexible body (4) with flanges (2, 3) at each end of the body (4), a bore (5) through the body (4) with permanently open ends (6) and a normally closed off central portion where there is engagement between opposed portions (9) of inner surfaces of the body bore (5). The bore (5) is openable by subjecting the exterior of said body (4) to negative pressure when mounted in a membrane mounting chamber.
(FR)
L'invention porte sur une membrane (1) utilisée dans un dispositif de pompage. La membrane (1) est constituée d'un corps flexible allongé (4) pourvu de rebords (2, 3) à chaque extrémité du corps (4), d'un trou (5) ménagé à travers le corps (4) et dont les deux extrémités se terminent par des ouvertures permanentes (6), et d'une partie centrale habituellement fermée, où les parties opposées (9) des faces internes du trou (5) viennent en contact l'une avec l'autre. Pour ouvrir le trou (5), il suffit de soumettre l'extérieur dudit corps (4) à une pression négative lorsqu'il est fixé dans une chambre de montage de membrane.
