Abstract (en)
[origin: WO2009141511A1] The invention relates to an improved pumping device which provides good sealing with a reduced number of components, owing in particular to the use of a valve including at least: a rigid retaining ring (52) clamped in a cylindrical portion (45) extending from a bellows (44); a flexible resilient diaphragm connected at the periphery threof to the retaining ring and including a domed part (51) curved towards the outside of the pumping chamber (3), said domed part having a slot (F) that divides the domed part into several portions; and a sleeve (534) extending from the ring outside the pumping chamber and coming into sealed contact around a hollow member (65) inside which an outlet duct (61) opens into a distribution port (611), the aforementioned portions of the domed part moving apart during expulsion and moving back together during suction.
