Definitions

  • the invention relates to a storage of a gas piston in a weapon system for the weapon and feed drive.
  • a weapon system for the weapon and feed drive.
  • the use of longer closing springs and closing spring sleeves is being considered.
  • the storage of the / the gas piston for the weapon and feed drive is now made on or in the barrel, the gas piston removed from the weapon housing.
  • the closing springs and the closing sleeves of the entire space in the weapon housing is available.
  • self-propelled weapon systems such as a gas pressure loader
  • the reloading and movement of a closure is done by the pressure of the powder gases. These act through holes and at least one gas piston system on the closure.
  • Such a weapon system with closing spring device is in the DE 10 2009 056 253 B3 treated.
  • the CH 229 628 A discloses a gas pressure supercharger in which the gas piston influenced by the tapped gases of the barrel surrounds the barrel in a sleeve-like manner and brings the closure for unlocking and returning after the shot via rods or the like.
  • the gas piston is designed here so that it surrounds the rear end of the barrel and also as a support member which can be locked with the barrel closure piece.
  • a propulsion system for a gas pressure supercharger which comprises at least two gas piston systems. These are aligned parallel to the barrel and arranged mirror-symmetrically to the longitudinal sectional plane of the gas pressure supercharger.
  • the gas piston systems are in turn guided to the front end of the gun barrel and coupled at its rear end via an intermediate piece with the closure.
  • the proposed closing springs are in turn involved at the rear end of the closure.
  • the DE 10 2005 062 758 B relates to a gas take-off arrangement for the gun barrel, the barrel bore is in communication with a gas cylinder, which is provided with a first gas outlet opening, which cooperates with a throttle element. Run, gas cylinder, first gas outlet opening and throttle element are formed so that a temperature-induced change in length of the barrel causes a relative movement between the gas cylinder and the throttle element.
  • Other embodiments include, instead of a gas piston system with direct connection to the closure, a gas piston which cooperates with a closing spring system on the closure.
  • closing springs and drive elements are housed in a common housing, the weapon housing. This fact limits the maximum possible length of the closing spring. The limited space finally brings with it the disadvantage that these closing springs can no longer sufficiently absorb an increase in the load change on the closing springs.
  • the invention has the object to allow an increase in the load change on the closing springs to eliminate the known disadvantages.
  • the present invention is based on the idea to absorb an increased load change of the closing springs by as long as possible, maximum springs of a closing spring.
  • it is therefore proposed not to provide the storage of the gas piston as before in the common housing, the weapon housing, but to take this out of the housing.
  • the entire length of the weapon housing for the integration of longer and stronger springs available.
  • This is achieved by the / the gas piston (drive element) is now stored with the necessary gas channel / gas channels on or in the barrel / gun barrel.
  • the gas piston is connected via this gas channel / channels with the gun barrel.
  • a gas pressure charging device which is located above the gun barrel, describes the DE 32 44 316 A1 , In this case, the properties of a recoil charger are impressed on the gas pressure charging device.
  • the problem of the load change is also not considered here. Rather, it should be noted that the mass of the slider and the force of the spring are selected so that even with different types of ammunition a perfect charging process is guaranteed.
  • the gas piston (s) paged out of the weapon housing according to the present invention is / are preferably housed in a separate gas piston housing mounted on or around the weapon barrel.
  • the necessary gas channels are in turn integrated in the gas piston housing.
  • gas piston housing may also be part of the weapon barrel and integrated into it.
  • the gas can be guided via separate gas guides to the gas piston (gas piston housing, weapon barrel).
  • the closing spring device is integrated in the weapon housing so that the gas piston can actuate and move the closing spring sleeve. Accordingly, the weapon housing in this area is open to the gun barrel, so that the gas piston can continue to act directly on the closing spring device.
  • a weapon system with a weapon barrel, a weapon housing and a shutter guided in the weapon housing is proposed.
  • This closure can be moved by way of at least one gas piston and a closure spring device which adjoins this structurally following gas spring cooperating with the gas piston.
  • the gas piston is now stored on or in the barrel and only the closing spring device is integrated in the weapon housing.
  • the 10 is a gas pressure loader comprising a weapon housing 1 and a gun barrel 2.
  • the weapon barrel 2 is integrated at the end in the front region of the weapon housing 1.
  • the cartridge feed of a cartridge or ammunition 11 in the cartridge chamber 8 of the gun barrel 2 is conventionally via a closure 7.
  • the closing spring devices 13 interact functionally with one gas piston 4 each.
  • the gas piston 4 are in turn now in a gas piston housing 3, which is arranged in the rear region of the gun barrel 2, integrated.
  • the gas piston housing 3 may also be part of the gun barrel 2.
  • the closing spring devices 13 each comprise a closing spring sleeve 6 and a closing spring 5, wherein cams 9 of the closing spring device 13 engage the closure 7.
  • the Schffyfedervoriquesen 13 are in turn integrated in the weapon housing 1.
  • the gas channels 14 may be part of the gas piston housing 3 at a close to the weapon housing gas sampling. If the gas removal further forward, the gas supply to the gas piston via separate feeds done, which are fed into the gas piston housing (not shown).
