Abstract

Pompe à diaphragme. Elle comprend un clapet circulaire à ressort plat qui est disposé au voisinage du diaphragme et qui est destiné à réduire les chocs hydrauliques et l'usure mécanique résultante du diaphragme Le clapet constitue une barrière qui empêche les jets de fluide hydraulique comprimé de frapper directement la membrane du diaphragme et il constitue un élément de fermeture réduisant les effets des chocs hydrauliques sur cette membrane. Application au pompage de liquide tel que la peinture, etc.
