Abstract

Pompe à membrane permettant d’amener un fluide de faible viscosité, tel que de l’air, sous haute pression à l’aide d’un moyen d’amenée de taille réduite. La pompe est branchée sur un tuyau d’amenée et un tuyau de refoulement et refoule un fluide entre le tuyau d’amenée et le tuyau de refoulement. Elle comprend un carter doté d’une chambre d’accumulation qui communique avec le tuyau d’amenée et le tuyau de refoulement par l’intermédiaire d’un clapet antiretour et qui accumule temporairement le fluide ; une membrane montée à l’opposé de la chambre d’accumulation et entraînée de façon à se dilater et à se contracter pour aspirer le fluide présent dans le tuyau d’amenée dans la chambre d’accumulation et le refouler ensuite dans le tuyau de refoulement ; et une partie d’entraînement de la membrane servant à dilater et à contracter la membrane. Le bord circonférentiel extérieur de la membrane est doté d’un tube annulaire permettant de la fixer sur le carter. La membrane se dilate et se contracte par déformation élastique du tube.
