Abstract

Die Erfindung betrifft ein Kraftelement nach einem Gehäuse (5), in dem ein gaserzeugendes Antriebselement (1) und ein Kolben (2a) mit einem auf dem Kolben (2a) angeordneten Stößel (2) angeordnet sind, wobei der Kolben (2a) von den erzeugten Antriebsgasen des Antriebselementes (1) in Austrittsrichtung des Stößels (2) aus dem Gehäuse (5) beschleunigbar ist.
Zur Vereinfachung der Herstellung des Kraftelements wird vorgeschlagen, dass im Gehäuse (5) eine an ihren Stirnseiten offene Zylinderhülse (3) angeordnet ist, wobei an ihrer ersten Stirnseite das Antriebselement (1) eingeschoben ist und an ihrer zweiten Stirnseite der Stößel (2) angeordnet ist.
