Abstract

Es wird ein Ventil zum Steuern von Flüssigkeiten vorgeschlagen, welches einen Piezoaktor (4) und einen den Hub des Piezoaktors (4) übertragenden mechanischen Übersetzer aufweist. Über dem mechanischen Übersetzer ist ein mit einem Kolbenelement (13) in Verbindung stehendes Ventilglied (14) betätigbar. Der mechanische Übersetzer weist eine Membran (11) auf, für welche der Hub des Piezoaktors (4) auf das Kolbenelement (13) des Ventilgliedes (14) übertragen wird.
