Definitions

  • the invention relates to a self-loading weapon with a gas pressure control, in which a run is connected via a gas pressure line to a pressure chamber in front of a piston in a closure carrier.
  • Gas pressure controls for self-loading weapons are known above all in two forms, namely in a direct and an indirect form.
  • direct gas pressure control of the gas stream gas pressure
  • this system involves some functional insecurity with weak charges.
  • the closure carrier is influenced by a piston system.
  • the description of this control can be found, for example, in WO 2009 137132A1, WO 1999005467 A1 or also DE 721 591 A1. Above all, reference is also made to the so-called AR rifle, which is described for example in EP 55 307 A1.
  • the object of the invention is to develop a self-loading weapon of the above type, which ensures extreme reliability even at low loads.
  • a longitudinal bore is provided in a piston rod which, in an open position, connects a pre-compression space after the run to the pressure space in front of the piston.
  • the direct coupled with the indirect gas pressure control exploited the advantages of both gas pressure controls and eliminates their disadvantages.
  • the cartridge is kept as long as possible in the running, on the other hand, the new cartridge is pushed back into the barrel very early in the return of the system.
  • the piston rod is still associated with its own sliding piston, which cooperates with the piston rod in the pre-compression space.
  • This sliding piston can be connected to the piston rod, but it can also slide independently in the pre-pressure chamber, wherein the pre-pressure space is formed by a cylinder.
  • This cylinder communicates with a gas block, whereby the gas block can sit on the barrel.
  • the cylinder close to the closure carrier, whereby the functionality according to the invention is in no way impaired.
  • the piston rod itself should be separated or integrally connected to a gas receiver, which in turn is assigned to the closure carrier.
  • the longitudinal bore in the sliding piston should have a larger diameter than the longitudinal bore in the piston rod. This has the effect that, after or during the filling of the pressure chamber in front of the piston in the closure carrier, an increased pressure build-up in the pre-compression chamber occurs, which leads to a very rapid retraction of the sliding piston and piston rod together with the closure carrier.
  • Figure 1 is a longitudinal section through a schematically illustrated
  • FIG. 2 shows a schematically illustrated longitudinal section through the region of the self-loading weapon according to FIG. 1 with the system open.
  • FIGS. 1 and 2 a barrel 7 and a closure carrier 6 are shown by a self-loading weapon according to the invention, in which a piston 5 moves for the advancement of cartridges. Before this piston 5, a pressure chamber 10 is formed, which causes a propelling of the piston 5 during its filling.
  • the barrel 7 is connected via a gas pressure line to the pressure chamber 10.
  • a gas pressure line for this purpose, at least one radial bore 11 is provided in a gas block 1, which is placed on the barrel 7.
  • This radial bore 11 opens into a transverse line 13 in a connection 12, which connects a cylinder 2 with the gas block 1.
  • the compound 12 in turn is associated with a cylinder 2, which forms a pre-pressure space 14, in which the transverse line 13 opens.
  • a sliding piston 4 which is penetrated by a longitudinal bore 15.
  • This sliding piston 4 cooperates with a piston rod 8, which is also penetrated by a longitudinal bore 16.
  • the piston rod 8 is seated in a gas receptacle 3, in which a slanted line 17 is located, which is connected via a bore 18 to the pressure chamber 10.
  • the line opens at the level of the longitudinal bore of the sliding piston 4 in the pre-pressure chamber 14.
  • the sliding piston 4 moves only when the pressure chamber 10 is filled.
  • the constriction creates a back pressure that causes a very rapid opening of the entire closure after advancing the piston 5.
  • the control of this movement is also used when a diameter of the slant line 17, which leads in the gas receptacle 3 to the pressure chamber 10, about the same diameter as the longitudinal bore in the piston 4th

Abstract

L'invention concerne une arme semi-automatique dotée d'une commande à pression de gaz, sur laquelle un canon (7) est relié au moyen d'une conduite de pression de gaz (11, 13, 15, 17, 18) à une chambre de pression (10) en amont d'un piston (5) dans un support de culasse (6). Selon l'invention, dans une tige de piston (8) est ménagé un alésage longitudinal (16) qui relie, dans une position d'ouverture, une chambre de pression préliminaire (14) en aval du canon (7) à la chambre de pression (10) en amont du piston (5).
