Abstract:
(EN) The invention relates to a method for operating a pneumatic adjusting element comprising an adjusting body and an adjusting element therefor, the length and height of the inner space of the adjusting body (2) being variable according to pressure, particularly positive pressure of a pressure medium, a minimum end position of the adjusting body being approached by subjecting the inner space of the adjusting body to negative pressure extracted from a negative pressure accumulator (6), the negative pressure in the negative pressure accumulator being produced by a beam pump embodied as an ejector (14), the driving medium thereof being a pressure medium flowing out of the inner space of the adjusting body.
(FR) L'invention concerne un procédé pour faire fonctionner un élément de réglage pneumatique comprenant un corps de réglage, ainsi qu'un élément de réglage pour ledit procédé. L'espace intérieur du corps de réglage (2) est variable en longueur ou en hauteur en fonction de la pression, en particulier de la pression positive d'un milieu sous pression. Une position d'extrémité minimale du corps de réglage est atteinte en soumettant l'espace intérieur de ce dernier à une pression négative, qui est prélevée d'un réservoir (6) à pression négative. La pression négative est générée dans le réservoir à pression négative par une pompe à vide réalisée sous la forme d'un éjecteur (14), dont le milieu propulseur est le milieu sous pression sortant de l'espace intérieur du corps de réglage.
(DE) Verfahren zum Betrieb eines pneumatischen Stellelementes mit einem Stellkörper sowie Stellelement dafür, wobei der Stellkörper (2) abhängig von Druck, insbesondere Überdruck eines Druckmediums in seinem Innenraum längen- oder höhenveränderbar ist, wobei eine minimale Endstellung des Stellkörpers durch die Beaufschlagung seines Innenraumes mit Unterdruck angefahren wird, der aus einem Unterdruckspeicher (6) entnommen wird, wobei der Unterdruck im Unterdruckspeicher durch eine als Ejektor (14) ausgebildete Strahlpumpe erzeugt wird, deren Treibmedium aus dem Innenraum des Stellkörpers ausströmendes Druckmedium ist.
