 vorderen Drittel ihrer Länge wieder austreten können und üi den mit Metallspänen angefüllten   Zwischenraum gelangen. Diese Metallspäne verhindern   nun ein rasches Entweichen der noch immer unter Pressdruck stehenden Gase nach dem hinteren gelochten Teil der Hülse   It,   so dass letztere nur allmählich und vollständig expandiert an diese Austrittsstelle gelangen und geräuschlos in das Freie entweichen. 



   Der vordere ungelochte Teil der Hülse e dient dazu, ein Vortreten der Gase vor   das Geschoss   vor dem Austreten des letzteren zu verhindern. 



   Die Fig. 5 zeigt eine weitere Ausführungsform der an den Schienen t'befestigten Stutzen d, während Fig. 6 eine nur zwei Hülsen   e1     und A'besitzende Vorrichtung veranschaulicht,   wobei die Innenwand des gelochten Teiles der Hülse   hl   noch mit einem feinen Stahldrahtgewebe   h2   überzogen ist. Wie Fig. 7 andeutet kann der gelochte Teil der Hülse hl auch durch Einschneiden von quer zur Längsachse stehenden Schlitzen   hs   erhalten werden.

 the front third of their length can emerge again and reach the intermediate space filled with metal chips. These metal shavings now prevent the gases, which are still under pressure, from quickly escaping to the rear perforated part of the sleeve It, so that the latter only gradually and completely expanded to reach this exit point and escape noiselessly into the open.



   The front unperforated part of the sleeve e serves to prevent the gases from advancing in front of the projectile before the latter emerges.



   FIG. 5 shows a further embodiment of the nozzles d attached to the rails t ', while FIG. 6 illustrates a device having only two sleeves e1 and A', the inner wall of the perforated part of the sleeve h1 still being covered with a fine steel wire mesh h2 is. As FIG. 7 indicates, the perforated part of the sleeve hl can also be obtained by cutting slots hs which are transverse to the longitudinal axis.

Claims

PATENT CLAIM: Knock-attenuating device in which the tensioned gases are deflected concentrically to and from the flight path in order to destroy their flow energy through Z4 bodies lined up and provided with a projectile passage opening and can expand before they pass into the open, characterized in that the inner housing containing the cell bodies is about two Third of the rear part of its length perforated or

is made of metal mesh and is surrounded by one or more alternately perforated housings on the front and rear ends, whereby the cavity formed between the outer and the closest inner housing is filled with aluminum chips, whereby a gradual perfect expansion of the tensioned gases is made possible, according to the . when firing a shot, shock effects and the development of fire glow are completely excluded.
