Description

Wenn in einem Servomotor infolge seines großen, Hubes oder in einer Meirbrankammer aus baulichen Rücksichten beim Eintritt des Druckmittels kein zwangsläufig bewegter Drosselstift zwecks Reinhaltung der Drosselöffnung eingebaut werden kann, so greift man zu der im nachstehenden beschriebenen Erfindung, welche durch die Strömungsenergie ein Reinhalten erzielt.
ίο Eine den Drosselstift umschließende abgefederte kolbenartige Buchse wird beim Strömen des Druckmittels in einem Drosselorgan in Richtung desselben und beim Druckausgleich gegen die Stromungsrichtung durch 15- eine Feder bewegt, so daß durch diese dauernde Bewegung ein Reinhalten der Drosselöffnung erzielt wird.If in a servo motor due to its large stroke or in a Meirbran chamber, for structural reasons when the pressure medium enters, a throttle pin that is not necessarily moved can be installed in order to keep the throttle opening clean, the invention described below is used, which achieves keeping clean by means of the flow energy.
ίο A spring-loaded piston-like bushing enclosing the throttle pin is moved by a spring when the pressure medium flows in a throttle element and against the flow direction when the pressure is equalized, so that the throttle opening is kept clean by this constant movement.

Ein Ausführungsbeispiel ist in der Abbildung dargestellt.An exemplary embodiment is shown in the figure.

In einem Membranventil 4 wirkt das durch ein Drosselorgan 3 eintretende Druckmittel durch Schließen des Ventils 4 gegen die Membranfeder 5 und beim Öffnen des Austrittes ι in umgekehrter Richtung aus. Hier- *5 bei wird während des Strömens des Druckmittels durch dessen Energie eine den Drosselstift umschließende kolbenartige Buchse 6 in dem Drosselgehäuse 3 gegen den Druck der Feder 7 in Richtung der Strömung und nach Schließen der Ausströmöffnung I durch die Feder 2 in einem Relais gegen die Strömungsrichtung bewegt, so daß durch diese dauernde Bewegung ein Reinhalten der ringförmigen Drosselöffnung zwischen der Buchse 6 und dem beweglich sitzenden Stift 8 erzielt wirdThe pressure medium entering through a throttle element 3 acts in a diaphragm valve 4 by closing the valve 4 against the diaphragm spring 5 and opening the outlet ι in the opposite direction. In this case, the pressure medium is flowing by its energy a piston-like bushing 6 surrounding the throttle pin in the throttle housing 3 against the pressure of the Spring 7 in the direction of the flow and after closing the outflow opening I through the Spring 2 moves in a relay against the direction of flow, so that lasting through this Movement keeping the annular throttle opening between the bushing 6 and the movably seated pin 8 is achieved
