Title (EN) MEMBRANE COMPRISING PUMPING DEVICES
(FR) MEMBRANE MUNIE DE DISPOSITIFS DE POMPAGE.
Abstract: front page image
(EN)The invention relates to a pumping device comprising a variable-volume pumping chamber (2) with at least one inlet (3) which is equipped with an intake valve (4) and an outlet (5) which is equipped with a discharge valve (6). According to the invention, the pumping chamber (2) is defined by at least one flexible wall (7) which can move in response to an actuation force in order alternatively to increase and decrease the volume of the chamber (2) and create a pumping action. The aforementioned flexible wall (7) is multi-layered and comprises (i) a flat element (8) with a geometry that is sensitive to variations in the electric voltage applied thereto and (ii) at least one electrically-insulating flexible layer (12, 21) which is disposed on either side of said flat element (8).
(FR)Dispositif de pompage comportant une chambre de travail (2) de volume variable, avec au moins un orifice d'entrée (3) muni d'un clapet d'admission (4) et un orifice de sortie (5) muni d'un clapet de refoulement (6), la chambre de travail (2) étant limitée par au moins une paroi flexible (7) pouvant se déplacer, en réponse ô un effort d'actionnement, pour faire augmenter et diminuer alternativement le volume de la chambre (2) et créer un pompage. La paroi flexible (7) est multicouche et comprend un élément plat (8) dont la géométrie est sensible aux variations d'une tension électrique appliquée ô cet élément, et au moins une couche flexible (12, 21) isolante électriquement située de chaque côté de l'élément plat (8).
