57	Abstract	AB	Ein Mehrwegeventil, insbesondere zur Verwendung in Dialyse-Geräten. Das Ventil besitzt einen Ventilkörper (1), durch den Zufluß- (2) und Abflußkanäle (3a, 3b) geführt sind. Am Ventilkörper (1) sind zwei Membranen (4, 5) so angeordnet, daß zwischen einer ihrer Oberflächen und einer Oberfläche des Ventilkörpers (1) jeweils eine Ventilkammer (6, 7) gebildet wird. Die Ventilkammern (6, 7) sind miteinander und mit einem gemeinsamen Zuflußkanal (2) verbunden. In mindestens einer Ventilkammer (6, 7) ist ein Ventilsitz (6a, 7a) angeordnet, über den diese Ventilkammer mit einem Abflußkanal (3a, 3b) verbindbar ist. Den Ventilsitzen (6a, 7a) gegenüber liegen in die Membranen (4, 5) einstückig integrierte Ventilteller (4a, 5a). Die Membranen (4, 5) sind über eine in ihrer Bewegungsrichtung starre Kopplungsvorrichtung (8), die außerhalb der Ventilkammern (6, 7) und der Zufluß- und Abflußkanäle (2, 3a, 3b) angeordnet ist, miteinander so verbunden, daß sie sich in bezug auf die Ventilkammern (6, 7) gegensinnig bewegen. Es ist eine Betätigungsvorrichtung vorhanden, die beispielsweise eine Magnetspule (10) sein kann.
