Definitions

  • a gas piston is arranged in a gas cylinder.
  • the gas cylinder is largely closed at one end, so that between the gas piston end face and the end wall of the gas cylinder, a pressure chamber is formed which communicates with the interior of the barrel.
  • a pressure chamber is formed which communicates with the interior of the barrel.
  • the resulting force acts on the power piston on a drive linkage, which is part of the loading mechanism in the weapon, and the cartridge supply and removal, the closure movement, and possibly the tensioning of the trigger mechanism causes.
  • this mechanism is driven, so long the trigger is held in the pulled position.
  • the detonation energy released during the firing is thus diverted partially for the weapon drive.
  • the flow cross-sections, the design of the gas piston and the pressure chamber are tuned to a particular weapon that a desired firing frequency, the so-called. Cadence is set, and a mechanical overload of the drive mechanism is prevented.

  • the gas entering the gas cylinder from the barrel partly exits the gas cylinder or the pressure chamber into the environment, so that a lower pressure acts in the pressure chamber compared to the barrel.
  • Such an embodiment is also known from DE 196 15 181.
  • Changes to the weapon or the ammunition also change the gas pressure conditions in the barrel bore or in the gas cylinder. If, for example, a normally equipped weapon - with a muzzle brake - alternatively provided with a muffler, so increases the gas pressure in the barrel bore and thus also in the gas cylinder or in the pressure chamber. As a result, the working piston is accelerated more. This results in that also the loading or repeating process is accelerated in an automatic weapon. The same effect occurs when a different type of ammunition is used (higher propellant charge, higher projectile mass). The so accelerated charging also increases the cadence. This is accompanied by an increased consumption of ammunition and the mechanical stress on the weapons components is increasing rapidly.
  • the object of the present invention is to provide an improved gas take-off device which at least partially eliminates the problems described above.
  • the invention is characterized in that the effective flow cross-section is tuned to a weapons configuration via a separate insert.

  • Claim 6 relates to a development in which a specially trained indentation has effective surfaces which cooperate with a securing element, so that over the active surfaces of at least one of the features Stellanschlag, latching surface, built-in fuse is realized.
  • Stellanschlag means in this context that the adjustment of the insert is prevented beyond certain limits;
