are surrounded by the compressed gas being retained inside the compressed gas tank 20 it applies to all embodiments illustrated in the drawings that the igniter 10 the ignition chamber 30 and the bursting element bolder 13 respectively and the first bursting element 14 may be arranged substantially coaxially within the compressed gas tank 20 a second bursting element 24 which is held at the distal end of the compressed gas tank 20 in a further second bursting element holder 23 may be disposed equally coaxially within the compressed gas tank the second bursting element 24 preferably equally takes the shape of a bursting disk the second bursting disk may be configured substantially analogously to the first bursting disk the connection between the further second bursting element holder 23 and the compressed gas tank 20 is preferably established by welding in particular the further second bursting element holder 23 may be tightly connected to the compressed gas tank 20 by capacitor discharge welding proximally with respect to the second bursting element 24 a filter 29 extends from the further second bursting element holder 23 info the interior of the compressed gas tank 20 moreover a diffusor 22 is attached to the distal end of the compressed gas tank 20 the diffusor 22 may be connected to the compressed gas tank 20 by crimping the diffusor 22 substantially forms a bulged cap having lateral outlet openings for the compressed gas disposed in the compressed gas tank 20 as well as for the burn off gas additionally generated by the propellant charge 18 in order to prevent the propellant charge 18 from being inadvertently ignited in the combustion chamber 16 during welding of the further second bursting element holder 23 with the.
