Beschreibung
Zusammenfassung:	A water filtration device (1) comprises various hoses (22, 23A, 23B, 24, 25A, 25B) for connection between different parts of the filtration device (1) and a rotatable cam system (20, 20A) which, during backwash cycles, is rotated so as to clamp various the hoses in predetermined sequences for thereby controlling the direction of the flow of water through the tubing system. Electrical pinch valves are use alternatively to a cam shaft. L'invention concerne un dispositif de filtration d'eau (1) comprend divers tuyaux souples (22, 23A, 23B, 24, 25A, 25B) pour la connexion entre différentes parties du dispositif de filtration (1) et un système de came rotative (20, 20A) qui, pendant des cycles de lavage à contre-courant, est mis en rotation de façon à serrer divers tuyaux flexibles dans des séquences prédéterminées pour ainsi commander la direction de l'écoulement d'eau à travers le système de tubage. Des vannes à manchon électriques sont utilisées en variante sur un arbre à cames.
