Abstract

Pour inverser le mouvement, les pompes à piston et/ou à membrane à actionnement hydraulique connues utilisent de l'énergie électrique ou un tiroir de commande/piston de commande. Cette nouvelle pompe à piston/à membrane autodémarrante, à fonctionnement hydraulique ou pneumatique, doit être de structure purement mécanique et fonctionner correctement, même lorsque la pression d'entraînement est faible, ce qui est important, notamment en cas de fonctionnement pneumatique. Dans cette nouvelle pompe à piston et/ou à membrane il est prévu, sur une tige, un piston de travail et deux membranes de refoulement qui sont reliées à une bascule située à l'intérieur, par l'intermédiaire de deux raccordements élastiques. L'inversion du mouvement de la pompe s'effectue par inversion des quatre soupapes situées à l'intérieur, pilotées par deux aimants permanents fixés sur une bascule. Cette pompe s'utilise pour le refoulement purement mécanique d'un liquide à l'aide de la pression d'un liquide d'entraînement.
