Abstract

Die Erfindung bezieht sich auf eine Einrichtung zum Verstellen von zueinander beweglichen Elementen, umfassend eine mit einem Arbeitsfluid beaufschlagbare Kolben-Zylinder-Anordnung mit doppelwirkendem Zylinder (10) und ortsfest angeordneter Kolbenstange (14), entlang der der Zylinder verschiebbar ist, der in Endstellungen verriegelbar ist und von dem ein zum Verstellen des Elements führendes Verbindungselement ausgeht. Um ein sicheres Verstellen und Verriegeln zu ermöglichen, wird vorgeschlagen, dass die Kolbenstange (14) eine von dem Arbeitsfluid beaufschlagbare Längsbohrung (24) aufweist, dass innerhalb der Längsbohrung zumindest ein Schaltzylinder (26, 28) axial verschiebbar angeordnet ist, der über ein erstes Federelement (34, 36) entgegen von dem Arbeitsfluid erzeugter Kraftbeaufschlagung verschiebbar ist, und dass die Kolbenstange von der Längsbohrung ausgehend von zumindest einem radial verschiebbaren Verriegelungselement (62, 64, 66, 68) durchsetzt ist, das bei sich in einer Endstellung befindlichem Zylinder (10) bereichsweise in einer Aufnahmekammer (16, 18) von diesem erstreckt und in dieser durch Anliegen an dem Schaltzylinder gehalten ist.
