Abstract

Die Erfindung bezieht sich auf einen Aktuator mit einem an seinem einen Ende geschlossenen Zylinder 1, in dem ein gegenüber der Zylinderinnenwand 6 abgedichteter Kolben 3 den Zylinderinnenraum in eine Arbeitskammer 7 und eine weitere Kammer 8 trennend verschiebbar angeordnet ist. Dabei weist der Kolben 3 eine einseitige Kolbenstange 9 auf, die durch die weitere Kammer 8 hindurchragt und aus dem zweiten Ende des Zylinders 1 herausgeführt ist. Durch eine von einer Zündeinrichtung zündbare pyrotechnische Einrichtung ist eine Druckgasbeaufschlagung des Kolbens in Ausfahrrichtung auslösbar. Die pyrotechnische Einrichtung ist in oder an dem Kolben 3 angeordnet, wobei eine Ansteuerleitung von der pyrotechnischen Einrichtung druckdicht abgedichtet durch eine axiale Ausnehmung in der Kolbenstange zu der außerhalb des Zylinders angeordneten Auslöseeinrichtung der Zündeinrichtung führt.

The invention relates to an actuator with a closed at its one end of the cylinder 1, in which a relative to the cylinder inner wall 6 sealed piston 3, the cylinder interior in a working chamber 7 and a further chamber 8 is arranged displaceably displaceable. In this case, the piston 3 has a one-sided piston rod 9, which protrudes through the further chamber 8 and is led out of the second end of the cylinder 1. By a ignitable by an ignition pyrotechnic device a pressurized gas loading of the piston in the extension direction can be triggered. The pyrotechnic device is arranged in or on the piston 3, wherein a drive line from the pyrotechnic device pressure-tight sealed by an axial recess in the piston rod to the outside of the cylinder arranged release device of the ignition device leads.
