Beschreibung
Zusammenfassung:	A pyrotechnic actuator, for an active hood, comprises: a container 22 for a gas generator 24; a cylinder 1 incorporating a moving piston 2; and a compressed gas line 18,20 that joins the container 22 with the cylinder 1, characterised in that a filter body 17,27,28 is arranged in the compressed gas line 18,20. The filter body 28 may deflect on its surface a gas stream passing through the compressed gas line 18,20. The filter body 17 may be hollow and its inner cavity 18 may form a downstream section of the compressed gas line 18,20.
