Abstract
A cartridge ammunition, in particular grenade ammunition, is provided that includes a projectile and a propellant charge case for accommodating the projectile and a propulsion, having a high pressure chamber and a low pressure champer, wherein the projectile and the propellant charge case are fastened to one another by way of a connection. The connection includes a membrane having at least one target braking point/opening point, which opens at a predetermined pressure in the high pressure chamber of the propulsion.
Claims8
A cartridge ammunition comprising:
- a projectile;
- a propulsion charge case for accommodating the projectile;
- a propulsion device having a high pressure chamber and a low pressure chamber, and
- a throttle pin,
- wherein the projectile and the propulsion charge case are attached to each other by a connection portion that includes a membrane provided adjacent thereto, the connection portion and the membrane surrounding the throttle pin, and the membrane having at least one predetermined breakage point/opening point that opens at a predetermined pressure in the high pressure chamber of the propulsion device, and
- wherein an annular hollow cavity is provided adjacent to the membrane, at a position that is between the membrane and the high pressure chamber along an axial direction of the throttle pin, the annular hollow cavity is formed so as to surround the throttle pin.
