Abstract

Üblicherweise führen Ventileinrichtungen zum Öffnen bzw. Schließen des Ventils entweder eine Hub- oder eine Drehbewegung aus. Bei der reinen Drehbewegung entstehen Probleme aufgrund des Verschleisses zwischen dem Schaltelement (2) und dem Steuerelement (10) einer Ventileinrichtung durch die starke Reibung. Bei Hubventilen entstehen Probleme insbesondere durch Verklebungen zwischen diesen beiden Elementen.Normally, valve devices for opening or closing the valve perform either a lifting or a rotary movement. In the pure rotary motion problems arise due to the wear between the switching element (2) and the control element (10) of a valve device by the strong friction. With lift valves problems arise in particular by bonds between these two elements.

Die vorliegende Erfindung hingegen nutzt die Vorteile der Dreh- und Hubbewegung und kombiniert diese miteinander. So werden durch die Drehbewegung vorher entstandene Verklebungen und Ablagerungen gelöst bzw. abgeschert, während durch die gleichzeitige Hubbewegung ein zu großer Verschleiß durch Reibung zwischen dem Schaltelement (2) und der Steuerfläche (10) weitestgehend ausgeschlossen ist.

Figure imgaf001
The present invention, however, takes advantage of the rotational and lifting movement and combines them together. Thus, by the rotational movement previously incurred adhesions and deposits are released or sheared, while due to the simultaneous lifting movement too much wear due to friction between the switching element (2) and the control surface (10) is largely excluded.
