Definitions

  • the invention relates to a gas pressure control device on a machine gun, the breech and / or ammunition supply device can be actuated by the gas pressure generated during the shot, the gas being supplied from the weapon barrel via a nozzle in a gas channel to the device.
  • Conventional machine guns have one or two gas channels with gas nozzles of the same diameter for driving the weapon breech.
  • a nozzle of a different diameter is usually provided for driving the ammunition supply device.
  • the compressed gas developing during the shot actuates the breech or the ammunition feed device via the nozzles.
  • the nozzles are built into the weapon barrel or into the weapon housing. If they are to be removed, the weapon barrel must be dismantled. This is expensive.
  • the object of the invention is to propose a device of the type mentioned at the outset, which allows different nozzles to be brought into the gas duct in a simple manner without the need to remove the weapon barrel.
  • the above object is achieved in a device of the type mentioned in the introduction in that at least two different nozzles are arranged in a nozzle holder and in that the nozzle holder is adjustably mounted, so that one of the nozzles in one position of the nozzle holder and one in a further position of the nozzle holder other of the nozzles is in the gas channel.
  • the effective nozzle in the gas channel can be exchanged. If several gas channels are provided, a suitable nozzle can be brought into each of the gas channels by a single adjustment process.
  • the nozzle holder can be adjusted by hand. It is also possible to control the adjustment remotely.
  • the gas pressure control device can be easily and quickly adapted to the respective type of ammunition or to extreme environmental conditions by means of the invention.
  • the gun barrel does not need to be removed for this.
  • the different nozzles provided are available in the nozzle holder.
  • the device ensures that the function of the closure device or the ammunition supply device is ensured at different gas pressures. By inserting the nozzle in question into the gas channel in question, it is ensured that the closure device or ammunition supply device connected to the gas channel is acted upon by the pressure which is suitable for the function and is reduced compared to the pressure in the weapon barrel.
  • Another advantage of the invention is that the cadence of the weapon can be controlled by inserting an appropriate nozzle into the gas channel.
  • a forced interruption of the function of the weapon can be achieved in that the nozzle holder is adjustable so that it closes the gas channel or channels.
  • the nozzle carrier is preferably designed as a ring encompassing the weapon barrel, which is rotatable about the longitudinal axis of the weapon barrel. In this way, a plurality of nozzles can be provided in a simple manner in the carrier for a plurality of gas channels arranged on the circumference of the weapon barrel, the relevant nozzle being placed in the gas channel by a corresponding rotation of the nozzle carrier.
  • a weapon barrel (2) is arranged on a weapon housing (1).
  • Three gas channels (3) run in the wall of the weapon barrel (2). In Figure 1, only one of the gas channels (3) can be seen.
  • the gas channels (3) open at one end into the inside of the gun barrel (2). At their other end they face gas channels (4) which are arranged in the weapon housing (1).
  • a sealing nozzle (5) is located in the wall of the weapon barrel (2) at the other end of each gas channel (3).
  • the circumference of the weapon barrel (2) is encompassed by an annular nozzle carrier (6). This can be rotated around the longitudinal axis of the weapon barrel (2). It lies axially between an end face (7) of the weapon housing (1) at which the gas channels (4) end and the sealing nozzles (5) of the weapon barrel (2).
  • a pair of nozzles (8, 9) is arranged in the nozzle carrier (6) for each of the three gas channels (3 or 4).
  • the nozzles (8, 9) have different free cross sections. They are inserted into corresponding holes (10) in the nozzle holder (6).
  • a locking pin (11) is radially displaceably mounted in the nozzle carrier (6) and is loaded by a compression spring (12). Three locking notches (13) assigned to the locking pin (11) are formed on the weapon barrel (2). In addition, a handle member (14) is attached to the nozzle holder (6).
  • FIGS. 1 and 2 show the central position of the nozzle holder (6) relative to the weapon barrel (2).
  • the locking pin (11) is in the middle locking notch (13) (see FIG. 2).
  • the nozzle (8) is in the gas channel (3,4). It stands between the part of the barrel that runs in the weapon barrel (2) Gas channel (3) and the part of the gas channel (4) running in the weapon barrel (2).
  • the pressure occurring in the weapon barrel (2) acts via the three gas channels (3), the sealing nozzles (5), the nozzles (8,8 ′, 8 ⁇ ) and the gas channels (4) on the gas channels ( 4) Connected devices, such as a locking device and ammunition feeder for the machine gun.
  • the sealing nozzles (5) serve to seal the gap between the nozzle holder (6) and the weapon barrel (2).
  • the nozzles (8,8 ', 8 ⁇ ) reduce the pressure to the level suitable for the devices mentioned.
  • the nozzles (8,8 ', 8 ⁇ ) will not set the pressure required for the devices to the correct level during the planned shot, then the nozzle holder (6) on the handle member (14) in the direction of the arrow (L ) turned to the left.
  • the locking pin (11) then snaps into the left locking notch (13).
  • the free cross sections of the nozzles (9) are dimensioned in such a way that they reduce the gas pressure of the weapon barrel (2) to the level suitable for driving the devices mentioned.
