Abstract (en)

An ignition unit for a propellant charge for ammunition, comprises an ignition tube (4) containing a transfer charge (5). The tube has a mantle with an ignition opening (9), and a thin walled protective tube (10) which protects the transfer charge against external influences. The protective tube outer wall is in contact with the inner wall of the mantle tube, and covers the ignition opening. The protective tube consists of a plastic film with a thickness of 0.1-0.8 mm. The film is adhered in the mantle tube or extruded.

Abstract (de)

Die Erfindung betrifft einen Treibladungsanzünder für patronierte Munition mit einem Anzündrohr (4), in dem sich eine Übertragungsladung (5) befindet, wobei das Anzündrohr (4) ein Anzündöffnungen (9) aufweisendes Mantelrohr (8) und ein zum Schutz der Übertragungsladung (5) gegen äußere Umgebungseinflüsse in dem Mantelrohr (8) angeordnetes dünnwandiges Schutzrohr (10) umfaßt, dessen Außenwand bündig an der Innenwand des Mantelrohres (8) anliegt und die Anzündöffnungen (9) verdeckt. Um zu erreichen, daß bei einem aus Kunststoff bestehenden Schutzrohr (10) auch bei rauher Handhabung sowie bei schockartigen Temperaturänderungen und erhöhter Feuchtelagerung über einen Zeitraum größer > 10 Jahre die Übertragungsladung (5) sicher gegen äußere Umgebungseinflüsse abgedichtet wird, schlägt die Erfindung vor, ein Schutzrohr (10) zu verwenden, das innenseitig eng an dem Mantelrohr (5) des Anzündrohres anliegt und aus einem dünnwandigen Material besteht, so daß der Rohrquerschnitt weitestgehend offen für den Durchgang und die Weiterleitung der Anzündung bleibt. Derartige Forderungen erfüllen folienartige Innenliner aus Kunststoff mit Wandstärken zwischen 0, 1 und 0, 8 mm, wobei das Schutzrohr (10) entweder durch Einkleben einer entsprechenden Folie oder durch Blasformen, Rotationsformen, Spritzgießen oder durch eine andere Extrudiertechnik in dem Mantelrohr (5) selbst hergestellt wird. <IMAGE>
