Definitions

  • the invention relates to a propellant lighter for ammunition with a cartridge Ignition tube in which there is a transfer charge.
  • a TLAnz is known in which to protect the transfer charge against external environmental influences within the jacket tube a thin-walled Protective tube made of a lead-tin alloy is arranged.
  • the protective tube lies flush against the inner wall of the casing tube, so that the ignition openings are covered. If the lighter is activated, the pressure surge punches the protective tube at the ignition openings.
  • the pilot light is ignited by the at the same time starting melting process of the lead-tin alloy weakened by energy withdrawal, from which a delay in flame propagation through the igniter openings follows into the propellant powder. This delay can be measured over time, so that short required ignition times (far below 50 ms) are not achieved.
  • a TLAnz of this type has the disadvantage that the material of the Protective tube contains lead components that are released when the cartridge is ignited and get into the environment as toxins and pollutants.
  • the use is likely of such a protective tube made of a metal alloy to an impermissible Increase the internal pressure of the propellant lighter.
  • a TLAnz is known from US 5,052,302, in which within a combustible Jacket tube is a fabric that includes the transfer charge Protective cover is arranged.
  • a protective cover is capable not the requirement for a secure sealing of the transfer charge external environmental influences over a longer period of time.
  • TLAnz The disadvantage of this TLAnz is that the respective plastic hose with mechanical Loads on the cartridge (e.g. during vibrations carried out in the laboratory) can be damaged because the edges of the hard propellant powder grains in the main charge of the cartridge are able to by rubbing and scoring to wear and damage the hose so that protection against intrusion of moisture in the TLAnz failed.
  • a TLAnz is known in which within the jacket tube a protective cover consisting of a plastic shrink film is arranged, which the transfer charge consisting of several ring tablets holds together and firmly encloses.
  • the ignition flame is inhibited, because the locking effect of the enclosing plastic is a delay-free quick Ignition of the entire transfer charge foiled, causing an increase in the ignition time is measured.
  • the object of the present invention is a propellant lighter to be specified which has an ignition tube with a protective tube arranged on the inside, which also applies to rough handling and shock-like temperature changes and increased moisture storage over a period greater than 10 years the transfer charge seals securely against external environmental influences.
  • the invention is based on the idea of using a protective tube that is tight on the inside of the casing tube of the ignition tube and from a thin-walled material, so that the pipe cross-section is largely open to the Passage and the forwarding of the ignition remains.
  • foil-like inner liner made of an edible metal or an edible metal alloy with wall thicknesses between 0.1 and 0.8 mm, preferably between 0.15 and 0.6 mm.
  • Edible metals or metal alloys are materials that behave like a typical metal at normal air pressure or contact pressure and normal temperature and thus form a secure barrier against moisture. At high pressure and / or high temperature, however, these metals react pyrotechnically (ie burn and The barrier effect of the thin-walled protective tube can thus be specifically eliminated by initiating the ignition of the propellant charge lighter.
  • the protective tube consists of a Mixed metal foil that is protected with a top coat.
  • Metallic cerium is the main ingredient the mixed metal alloy.
  • FIG. 1 shows the longitudinal section of a propellant charge lighter according to the invention, such as in the case of cartridges Tank ammunition can be used.
  • the propellant lighter designated 1 consists essentially of a head part 2 and one adjoining it in the direction of the longitudinal axis 3 of the igniter 1 Ignition tube 4.
  • the head part 2 which has a primer, not shown, as well contains an amplifier charge 7, is screwed with an external thread 6 the propellant lighter 1 in the bottom of the corresponding cartridge (not shown) Mistake.
  • the ignition tube 4 which is filled with a transfer charge 5, exposes itself a steel jacket tube 8 with ignition openings 9 and arranged on the inside Sealing in the form of an inner liner or protective tube 10 from an edible Metal or an edible metal alloy in foil form, which the Ignition openings 9 covers.
  • the inner liner or the protective tube 10 is on the front 11 of the ignition tube 4 closed and on its head part 2 of the propellant lighter 1 Page 12 sealed by means of a seal 13 made of an elastic material.
