| 摘要 |
The invention relates to a cartridge ammunition (1), in particular a grenade ammunition, comprising a projectile (1) and a high-pressure-low-pressure-drive system for expelling the projectile (11) from the cartridge case (2) thereof, wherein the high pressure-low pressure-drive system comprises a high-pressure chamber (12) receiving a propelling charge (9) and a low-pressure chamber receiving the high-pressure chamber (12), which chambers can be connected to one another in the wall (3) delimiting the high-pressure chamber (12) via one or a plurality of cross-flow channels (19) that become apparent by the pressure created during the ignition of the propelling charge (9). The cross-flow channels (19) are oriented in such a way that the direction (25) thereof in relation to the longitudinal axis (26) of the high-pressure chamber (12) differs from the radial direction (27). |
