Abstract

L'invention a trait à des dérivations (valves) pour l'écoulement contrôlé de liquides organiques, tels que le liquide céphalo-rachidien, comportant un organe d'actionnement de valve (tel qu'un piston) entre les orifices d'entrée et de sortie. L'organe d'actionnement de valve est sollicité vers un état dans lequel la valve est fermée, et comporte une face adjacente au côté amont de la valve (et, de préférence, isolée du côté aval de la valve) permettant à la pression de liquide du côté amont d'exercer une force d'ouverture sur la face pour solliciter la valve vers un état d'ouverture. Lorsque la force d'ouverture sur l'organe d'actionnement de valve dépasse la force de fermeture dans une certaine quantité, l'organe d'actionnement de valve déplace la valve vers l'état d'ouverture, permettant l'écoulement de liquide à travers le passage de liquide entre les ports d'entrée et de sortie.
