Abstract

Es sind Ventilvorrichtungen mit einem Gehäuse (2), einem Aktuator (4), der ein Drehmoment erzeugt, einer Getriebeeinheit (6), einem translatorisch bewegbaren Ventil (8), über welches ein Durchströmungsquerschnitt (40) geregelt freigebbar oder verschließbar ist, einem Getriebeabtriebsglied (26), welches derart mit dem Ventil (8) gekoppelt ist, dass die Drehbewegung des Getriebeabtriebsgliedes (26) eine translatorische Bewegung des Ventils (8) erzeugt und einem Federelement (44), weiches als Rückstellfeder dient, bekannt.
Die bekannten Ventilvorrichtungen weisen jedoch trotz der häufig vorhandenen Rückstellfeder ein relativ großes Getriebespiel auf.
Erfindungsgemäß wird zur Lösung dieses Problems vorgeschlagen, dass das Federelement (44) derart angeordnet ist, dass einerseits ein Zahnrad (20) oder eine Drehwelle (16) der Getriebeeinheit (6) und andererseits das Ventil (8) in Schließrichtung des Ventils (8) belastet sind.
