Flexible valves principally (although not necessarily exclusively) for automatic swimming pool cleaners are addressed. The valves have generally parabolic closure regions and do not present linear transverse cross-sections to water flowing through them. The closure regions may extend substantially below the transverse center lines of the valves, which additionally may include teeth (90) at or near hinges (88 A - B) of the closure regions. Including the hinges reduces likelihood of undesired wear at or near the outlets of the valves.
L'invention concerne des soupapes flexibles principalement (bien que pas nécessairement exclusivement) pour des systèmes de nettoyage automatique pour piscines. Les soupapes comportent généralement des zones de fermeture paraboliques et ne présentent pas de coupes transversales linéaires pour l'écoulement de l'eau entre elles. Les zones de fermeture peuvent s'étendre sensiblement sous les lignes transversales centrales des soupapes, qui peuvent en outre comprendre des dents (90) sur les charnières (88 A - B) des zones de fermeture ou près de celles-ci. Inclure les charnières réduit la probabilité qu'une usure non souhaitable ne se produise sur les sorties des soupapes ou près de celles-ci.
