Bei ersterem tem Maßstab in einem Ausführungsbeispiel gezeigt kommt beispielsweise reines NC-Pulver in Betracht, so und wird im folgenden an Hand dieses noch erläutert. Zweckmäßig soll es ein poröses Pulver sein. Neben Der gegossene oder aus porösem Pulver gepreßte einer großen Oberfläche,, die einen guten Anbrand kreiszylindrische Treibpulverkörper 1 ist an beiden sichert, hat ein solches Pulver insbesondere den Vor- Stirnseiten mittels der schlagempfindlichen Pulverteil, daß es sich schon bei verhältnismäßig geringen folie 2 abgedeckt.

exists both for the propellant powder body and the invention is largely free in the drawing in enlarged for the powder film. In the first system scale shown in an exemplary embodiment, for example, pure NC powder comes into consideration, and will be explained below with reference to this. It should expediently be a porous powder. In addition to the large surface that is cast or pressed from porous powder, which ensures a good burn-on of the circular-cylindrical propellant powder body 1 on both, such a powder has, in particular, the front end faces by means of the impact-sensitive powder part that it is covered with a relatively small film 2. The clear cross-section 3 is partially pressed can be compressed into a solid compact, 25 filled with the loose flake powder 4,

Both the cross-sectional dimensions and the latter must, unless a height of the powder ring 1 and the thickness of the film 2 impact-sensitive powder is used, only and the loose flake powder 4 are here self-assured that they are from one through Schlag understandably only to be understood as an example.

Claims

1 2 Mechanically ignitable patent claims connected with propellant powder bodies · The ignition element is in any case arranged or designed in such a way that the abutment required for the ignition is present in the ammunition itself, see above

1. Drive cartridge, in particular for devices for 5 that the danger of intended ignition is commercial use such as bolt-firing devices / This disadvantage can be accepted, although with ammunition for or the like, with a cast or pressed, military purpose , a preferably central recess and in but not in Treibkaftuschen for devices for their area a mechanically ignitable ignition commercial use, since such cartridges in the element having propellant powder body, that io trade can be freely acquired by everyone, characterized by the fact that the ignition and consequently much higher requirements than the recess of the propellant powder to make your Häridhabüngssicherheit shuL
The object of the invention is to avoid the pre-film (2) and / or one of the disadvantages mentioned in part of the recess, that is to say, a powder charge (4) that fills the body in a manner that forms the basis of the invention. 15 on the one hand the undesirable impurities of the

With such a residue that burns without residue The powder casing-free cartridge, which partially fills a closed recess, is advantageously the charge (4) is a loose flake powder. 30 risk of unintentional ignition overcome,

5. Drive cartridge according to one of claims 1 because the cartridge is a required for the ignition to 4, characterized in that the propelling abutment does not have itself, and "because even with powder body as a flat tablet with almost over the presence of such an abutment outside The entire height of the central recess of the cartridge is always an ignition recess is trained. 35 is resolved when a blow to the in the area of

Practice teaches, carry the previously known and used Cartridges do not meet this requirement or the burn-up of the propellant powder can be reduced only inadequate calculation, because measured a further proposal of the invention through the high internal pressure also occurring in the area of the recess with these cartridges there is always chipping side coating of the film with a through and tears on the wall of the cartridge shell and 55 impact ignitable mixture, for example tetrazene thus to be provided for residues in the cartridge storage of the Ge or Tetrazen Trizmät. in the advises. It is true that one can trap a recess that is closed on all sides in various ways tries to remedy this deficiency * for example, but also provide this partially with by the fact that on the cartridge case defined predetermined loose flake powder zones which can be ignited by impact trained, but all 60 have to fill.

Attempts to date have not achieved any decisive success. According to a further proposal of the invention
