Definitions

  • the invention relates to a mechanical initiation system for caseless ammunition according to the preamble of claim 1.
  • the firing pin is provided tribladungshunt section with an annular sealing lip.
  • This sealing lip leads at gas pressure from the propellant charge chamber by elastic expansion to an intimate contact with the inner wall of the through hole for the firing pin.
  • the passage hole for the striker is sealed backward upon ignition of a powder body in the propellant charge chamber.
  • the sealing lip is acted upon when igniting the powder body located in the propellant charge chamber directly from the hot, accelerated to high speeds combustion residues and Zündstoff puzzle. This leads after a certain number of ignition processes to a steadily progressing erosion of the sealing lip.
  • the invention has for its object to provide an initiating system of the type mentioned, with simple means a reliable sealing of the firing pin is realized in the intended for him through hole.
  • the invention has the advantage that in each path position of the firing pin a reliable sealing of the firing pin is ensured against the wall of the provided for him in the weapons shock bottom through hole.
  • FIG. 1 shows sections in longitudinal section, to an enlarged scale, not to scale, of an embodiment of the initiating system 10 for a caseless ammunition, of which the powder body 12 is shown in sections.
  • the powder body 12 is positioned in a powder cross slide 14.
  • a weapon thrust plate 16 Adjacent to the cartridge chamber 14 is a weapon thrust plate 16, which is formed with a through hole 18.
  • the through hole 18 is formed on its front side facing the cartridge chamber 14 with a circumferential extension 20.
  • a sealing bush 22 is arranged, which has a peripheral collar 24 on the front side.
  • the collar 24 is housed in the extension 20 so that the sealing bushing 22 is immovable axially rearward with respect to the weapon buttock 16.
  • the sealing bush 22 is formed with a firing pin through hole 26 in which a firing pin 28 is arranged axially adjustable.
  • the firing pin 28 is moved, for example by means of a (not shown) control piece from the initial position shown in Figure 1 in the drawn in Figure 2 end ignition position. This movement is indicated in Figure 1 by the arrow 30.
  • the sealing bush 22 disposed in the weapon butt 16 for the firing pin 18 is formed with a grease reservoir 32 connected to a grease source (not shown) by means of a grease channel 34 extending through the gun butt 16.
  • the firing pin 28 is formed with at least one circumferential fat groove 36.
  • the firing pin 28 is formed with two axially spaced circumferential fat grooves 36.
  • the fat grooves 36 are assigned to the fat reservoir 32, so that the fat grooves 36 are filled with fat 37 located in the fat reservoir 32.
  • the grease grooves 36 entrain the grease 37 in them, thereby forming a greasy film between the firing pin 28 and the through hole 26 in the sealing bushing 42 is generated, which contributes to gas sealing and to avoid traces of friction.
  • the through hole 26 is formed for the firing pin 28 at its front end facing the cartridge chamber 14 with an inlet portion 38 widening towards the chamber 14.
  • the inlet section 38 is frustoconically widened with a flat cone angle. Likewise, it is for example possible that the inlet section 38 is formed widened with a gentle radius.
  • the firing pin 28 is formed on the front side with a deflector 40, whose operation will be described in more detail below.
  • the deflector 40 is formed on a firing pin front part 42.
  • the firing pin front part 42 is formed on the rear side with an externally threaded portion 44.
  • the firing pin 28 is formed on the front side with a threaded bore 46.
  • the firing pin front 42 is screwed with its rear male threaded portion 44 in the threaded bore 46 of the firing pin 28.
  • the firing pin 28 is also formed on the front side with a circumferential sealing lip 48, which is determined or limited on the inside by a frustoconical tapering annular surface 50 backwards.
  • FIG. 2 also shows an ignition means 52 in which the firing pin 28 with its tip 54 projects into the end position in order to ignite the ignition means 52.
  • the operation of the initiating system 10 according to FIGS. 1 and 2 is as follows:
  • the firing pin 28 is driven by means of a drive, e.g. is an unillustrated control piece, accelerated in the direction of arrow 30 (see Figure 1), so that the tip 54 of the firing pin 28 is pushed into the powder body 12 and the ignition means 52.
  • a drive e.g. is an unillustrated control piece, accelerated in the direction of arrow 30 (see Figure 1), so that the tip 54 of the firing pin 28 is pushed into the powder body 12 and the ignition means 52.
  • end ignition position of the firing pin 28 is held until the gas pressure generated by the ignited powder body 12 has degraded. Only then is the firing pin 28 moved back again from the end firing position shown in FIG. 2 into the starting position shown in FIG. During these movements, the firing pin 28 moves with its fat grooves 36 into and through the grease reservoir 32.
  • the wall 37 of the through hole 26 is greased with the grease 37 remaining in the grease grooves 36.
  • the deflector 40 of the firing pin 28 prevents direct bombardment of the circumferential sealing lip 48 by accelerated powder and / or Zündffenmaschine.
  • the circumferential sealing lip 48 comes in the piercing movement of the firing pin 28 just before the transition edge between the cylindrical through hole 18 and the inlet section 38 to a stop.
