摘要
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.
