Abstract

Die vorliegende Erfindung betrifft ein Ventil zum Steuern von Flüssigkeiten, welches einen Piezoaktor (2), einen mechanischen Übersetzer (3) zur Übersetzung des Hubes des Piezoaktors (2), ein Rückstellelement (4) und einen Betätigungskolben (6) zur Betätigung eines Ventilglieds aufweist. Dabei ist mechanische Übersetzer (3) in Betätigungsrichtung des Piezoaktors zwischen dem Piezoaktor (2) und dem Rückstellelement (4) angeordnet. Somit übersetzt der mechanische Übersetzer (3) in Betätigungsrichtung den Piezoaktorhub und in umgekehrter Richtung die Rückstellkraft des Rückstellelements (4).
