Definitions
- the invention relates to a gas take-off assembly for a barrel of a gas-pressure self-loading weapon (e.g., a machine gun) having a gas cylinder communicating with the barrel bore and having a first gas exit port cooperating with a throttle element.
- a gas take-off device is known, for example, from DE 196 15 181.
- barrel denotes both a gun barrel with moves and fields as well as a smooth gun barrel.
- Directional indications such as top, bottom, front, back, right and left are given for an attacking weapon from the point of view of the shooter.
- 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 is in communicating communication with the interior of the barrel.
- the incoming gases build up a working pressure in the pressure chamber, which acts on the end face of the working piston.
- the resulting force acts via the power piston on a drive linkage, which is part of the loading mechanism in the weapon, and the cartridge feed and removal causes the closure movement, and possibly the tensioning of the trigger mechanism.
- the pressure chamber is provided with a gas outlet opening for pressure adjustment and - vote.
- 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.
- the gas quantity entering the pressure chamber from the barrel can be regulated via an adjustable valve (DE 648 391). With these measures, the flow and pressure conditions in the gas take-off arrangement can be matched to the weapon.
- a barrel change is not a problem in itself, the barrel is intended, but undesirable under conditions of use. Therefore, there is basically the problem with automatic weapons to keep the weft cadence as stable as possible, even in case of permanent use, in order to keep the weapon load low, to stabilize the ammunition consumption and to keep the intervals between necessary running changes as long as possible.
- a gas supply mechanism which has a spring-loaded control valve which is intended to allow a portion of the originating from the barrel of the weapon gases to escape in the event of excessive pressure and gastikutz limit the speed of movement of the movable parts ,
- This solution is intended for semi-automatic firearms, especially shotguns, and requires a spring loaded control valve.
- the object of the present invention is to provide an improved gas take-off device which at least partially eliminates the problems described above.
- a gas take-off device In this case, run, gas cylinder, gas outlet opening and a throttle element are designed and arranged so that the temperature-induced change in length of the barrel, which occurs at continuous fire, causes a relative movement between the gas cylinder and throttle element, so that the throttle element, the gas outlet opening more or less freely and thus the in the pressure chamber acting gas pressure stabilized according to the running temperature.
- a self-regulating gas sampling device is provided in which the change in length of the barrel changes the pressure and flow conditions in the gas cylinder so that the temperature-induced increased gas pressure in the barrel causes no significant pressure increase in the pressure chamber.
- claim 2 relates to a throttle element, which is arranged in the interior and / or outside of the gas cylinder.
- the relative movement is particularly easily ensured by the throttle element is fixed relative to a thermally less stressed housing component and the gas cylinder is fixed with respect to a running section.
- the throttle element is used to control the throttle element so the axial relative movement between the corresponding barrel portion and the housing.
- the throttle element is formed on a gas cylinder at least partially surrounding recording.
- the gas cylinder is arranged axially displaceable for receiving.
- This solution provides a structurally particularly simple operative connection between throttle element and gas cylinder and thus between the gas outlet opening and throttle element.
- the throttle element is designed as a sealing zone, which is formed on the receptacle and corresponding to the axial barrel displacement mounted in the gas cylinder gas outlet opening reduced or increased.
- the sealing zone pushes more or less over the first gas outlet opening and relocated or opened their cross-section and the resulting from the barrel bore forth in the pressure chamber pressure is more or less on the corresponding Covered or uncovered gas outlet opening reduced.
- the gas cylinder is connected to a connection part fixed to the barrel.
- this connector is also advantageously the communicating connection between the pressure chamber or gas cylinder and the barrel bore instead.
- the fixed connection with the barrel ensures that the gas cylinder moves according to the axial displacement of the barrel, so that the relative movement takes place between recording or arranged on the recording sealing zone and the gas cylinder or the gas outlet opening mounted therein.
- An interference fit ensures that the fitting and barrel are sealed against each other so that no gas leaks between the barrel and fitting.
- a positive connection via a pin can additionally take place.
- This pin can also be designed so that it fixes the connecting part and thus the gas cylinder in the desired circumferential position with respect to the barrel.
- the receptacle is connected via a sleeve which surrounds the gas linkage and thus protects, firmly connected to a housing component. This is on the one hand shielded the gas linkage and on the other hand, the temperature of the barrel largely decoupled fixation of the recording possible.
- an axially displaceable to the running axis support member may be additionally secured to the receptacle.
- This support element prevents transverse forces acting on the receptacle are transmitted to the gas cylinder and possibly affect the displaceable arrangement between the gas cylinder and recording.
- a further gas outlet opening may be provided in the gas cylinder in order to facilitate the tuning of the gas take-off device to a specific weapon configuration.
- this vote is particularly easy to perform by this additional gas outlet opening is arranged in a removable insert. The vote is made simply by choosing a corresponding insert with a correspondingly large gas outlet opening. It is also possible to make this vote, for example via a control valve according to claim 12.
- Claims 13 and 14 relate to a barrel with an inventive gas take-off device or a weapon, in particular a machine gun, with such a barrel.

- the ammunition (not shown) is strapped and automatically fed via a corresponding mechanism (not shown) to the arranged in the rear end of the barrel 10 cartridge chamber and ignited there.
- the ignited propellant catapulted the projectile from the cartridge case through the barrel bore 7, which runs concentrically to the so-called soul axis 8, forward out of the muzzle towards the target.
- a portion of the propellant gas passes through a tap hole 9, which extends transversely to the bore 7 radially in the barrel 10 and is coaxially connected thereto in the gas take-off 3 introduced gas channel 11 and the main channel 12 guided in the pressure chamber 14 formed by the gas cylinder 13.

- the gas outlet opening 29 moves relative to the front edge 31 of the recess 30 by the thermal expansion to the front.
- This condition is shown in FIG.
- the cross section of the gas outlet opening 29 is here largely exposed and the increased flow cross-section causes increased gas discharge and thus a pressure reduction in the pressure chamber 14, which compensates for the temperature-induced pressure increase in the bore 7.
