Embodiment Construction
[0016]FIG. 1 shows the bottom region 1 of a cartridge, having a case bottom 2 of metal and a combustible case 3. The propellant powder 4 within the combustible case 3 can be ignited with a centrally located propellant igniter 5.
[0017] According to the invention, a collar 7 that comprises an oxygen-releasing substance is arranged between the case bottom 2 and a cartridge-bottom region 6 of the combustible case 3.
[0018] Thus, if the cartridge 1 is positioned inside a gun barrel (not shown), then the propellant powder 4 is initially ignited with the propellant igniter 5, following the firing. The case 3 subsequently burns and sufficiently heats up the collar 7, so that it begins to release oxygen into the bottom region of cartridge 1 and thus also into the breech area of the gun.
[0019]FIG. 2 shows another exemplary embodiment of the invention, for which an oxygen-releasing substance takes the form of a ring-shaped element 8 that is positioned on the bottom part 9 of the propellant i...
