Definitions

  • plastic cases that share a common disadvantage, they namely have low structural strength and such cases tend to burst when fired.
  • a solution to a plastic case is known from patent document EP 1 388 726 . It is characterized in that its inner diameter along the main axis gets reduced towards the case bottom. In such a variant, there is no possibility of pressure regulation when the gunpowder propellant is activated.
  • the bullet 4 with annular projections 4a, 4b is inserted into an opening of the case 1.
  • the case 1 is provided at an input side for the bullet 4 with a groove 1 a, into which the annular projection 4a of the inserted bullet 4 fits, while the bullet 4 abuts with its annular projection 4b on an edge of the case 1. Good sealing between the opening of the case 1 and the bullet 4 is herewith achieved.
  • the empty section 2 of the case 1 is closed by the partition wall 3 which can be made at various heights of the case 1 during the manufacturing method.
  • the case volume is defined only by the size of the case, while various arrangements of the partition wall 3 in the cartridge of the invention, i. e. by changing or adapting the volume of the empty section 2, the pressure that builds up during activation of the gunpowder propellant 5 can be regulated.
  • the case 2 ends with the gunpowder propellant 5 which is inserted into the centre of the labyrinth-like internal part of the wall of the case 2.
  • the cartridge bottom 6, into which a firing cable 7 is inserted from the external side, is provided on the external side by labyrinth projections 8 which engage with corresponding cavities made in the internal wall of the case 2, thus forming a hermetically closed connection or joint.
  • the gunpowder propellant 5 When the gunpowder propellant 5 is activated, huge quantities of gas start to generate in the empty section 2 of the case 1.
  • the created pressure causes the bullet 4 to move away from the case 1, which then continues its path through a barrel and a fire line to a target.
  • the size of the empty section 2 of the case 1 can be mathematically very precisely determined as a function of the quantity of gunpowder propellant 5 and the spot of arrangement of the partition wall 3 for the desired speed of the bullet 4.
  • the speed of the bullet 4 can be regulated to such an extent that the ammunition can be designated as "less lethal ammunition" or NLA ammunition that is intended to temporarily incapacitate a target and has no lethal properties.
