Definitions

  • the invention relates to a pyrotechnic delay tube according to the preamble of claim 1.
  • a housing with predetermined breaking points on the side contains ignitable material which, when burned, develops hot gases, flames and pressure in the housing.
  • the predetermined breaking points break open at a corresponding pressure and the hot gases and flames radiate out of the housing.
  • the invention has for its object to propose a pyrotechnic delay tube that reproducibly ignites a propellant charge.
  • a fire extinguisher generator 1 has, inter alia, a mechanically actuated trigger trigger 2 with a delay tube 3 and a housing 4 with a propellant 5.
  • the delay tube 3 consists of a sleeve 10 with a primer 11 that can be triggered by a firing pin (not shown), a delay set 12, an end face 13 and bores 15 lying in a plane 14.
  • the bores 15 are arranged in a star shape according to FIG. 3 and have an angle 16 of 60 ° between them.
  • the delay set 12 extends almost over the entire cargo space 17 of the sleeve 10. It extends from a distance, not specified, from the primer 11 to the floor 13. The bores 15 are thus directly in the area of the delay set 12.
  • the axial distance 20 from A deepest point 21 of the bottom 13 is approximately 0.5 to 1.5 of the diameter 22 of the deceleration set 12, the optimized distance being 0.9 diameter 22 of the deceleration set 12.
  • the bottom 13 is formed in one piece with the sleeve 10.
  • the diameter 23 of the bores 15 is approximately 0.3 to 0.5 of the diameter 22 of the delay set 12.
  • the optimized diameter is 0.4 of the diameter 22 of the delay set 12.
  • the fire jet of the squib 11 causes the front ignition of the delay set 12 at 30.
  • the focal front reaches the plane 14 in which the holes 15 are arranged in a star shape. From the bores 15, the flames 40 radiate in a star or spherical shape on all sides and reproducibly ignite the propellant 5.
  • Essential to the invention is the spherical flame pattern with the diverging flames 40 and the long-lasting flame effect due to the distance 20.
  • the distance 20 represents the so-called flame reserve for the ignition of the propellant 5 Moving arrow 50 to point 21 reaches the upper edge of the bores 15 at 51.
  • the decisive factor is the set length designated 52 below the lower edge 54 of the bores 15.
