Abstract

A weapon system (10) is proposed with a weapon barrel (2) and a lock (7) guided in a weapon housing (3) which interacts with the gas piston (4) via at least one gas piston (4) and an adjoining gas piston (4) Closing spring device (13) is moved. There are gas channels (14) between the weapon barrel (2) and the gas piston (4). In order to ensure that a load change can be better excluded from the closing springs (5), it is provided that the gas piston (4) is mounted on or in the weapon barrel (2) and the closing spring device (13) is integrated in the weapon housing (1) .

Description

The invention relates to a storage of a gas piston in a weapon system for the weapon and feed drive. In order to achieve that such a weapon system can better absorb an increased load change, it is provided that the storage of the / the gas piston for the weapon and feed drive on / in the barrel, so no longer takes place in the weapon housing. As a result, longer closing springs and closing spring sleeves can be used.

In 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.

The CH 229 678 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.

From the DE 199 03 610 A a propulsion system for a gas pressure supercharger is known 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 comprise, instead of a gas piston system with direct connection to the closure, a gas piston which interacts with a closing spring system on the closure ( WO 2011/066893 A ).

Such closing springs and drive elements (gas piston) 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.

Here, the invention has the object to show a way to eliminate this disadvantage.

The problem is solved by the features of claim 1. Advantageous embodiments are listed in the subclaims.

The 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. In order to implement this idea, it is therefore proposed not to provide the storage of the gas piston in the common housing, the weapon housing, but to remove it from the housing, so that the entire length of the weapon housing can be used for the integration of long springs. This is achieved in that the / the gas piston (drive element) is stored with the necessary gas channels on or in the barrel / gun barrel. The gas piston is connected via gas channels with the gun barrel.

The gas piston (s) is / are preferably housed in a gas piston housing mounted on or around the weapon barrel. Alternatively, the gas piston housing may also be part of the 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.

The gas channels can be integrated in the gas piston housing. If a gas extraction at the front of the weapon barrel is desired, the gas can be guided via separate gas guides to the gas piston.

It proposes a weapon system with a gun barrel and a lock guided in a weapon case. This is at least a gas piston and this structurally subsequent, cooperating with the gas piston closing spring device movable. There are gas channels between the gun barrel and the gas piston. In order to achieve that a load change can be better absorbed by the closing springs, it is provided that the gas piston is mounted on or in the barrel and integrated the closing spring device in the weapon housing is. By this construction, the total length of the weapon housing can now be used for the closing springs alone.

Reference to an embodiment with drawing, the invention will be explained in more detail. The single figure shows a sketchy representation of the invention. It is assumed that a symmetrical drive system consisting of two gas piston and two Schließfedervorrichtungen.

With 10 is a gas supercharger marked, which is a weapon housing 1 as well as a weapon barrel 2 includes. The gun barrel 2 is at the end in the front area of the weapon housing 1 involved. The cartridge feed of a cartridge or ammunition 11 in the cartridge chamber 8th of the barrel 2 conventionally takes place via a closure 7 , This is, as already stated, preferably by two Schließfedervorrichtungen 13 inside the gun case 1 emotional.

The closing spring devices 13 act with one gas piston each 4 functionally together. The gas pistons 4 are in turn now in a gas piston housing 3 , which is in the rear of the barrel 2 is arranged, integrated. The gas piston housing 3 but it can also be part of the weapon barrel 2 be. The closing spring devices 13 each include a closing spring sleeve 6 and a closing spring 5 where cams 9 the closing spring device 13 to the lock 7 intervention. The closing spring devices 13 are in turn in the weapon housing 1 integrated. The gas extraction for the gas piston 4 of the gas pressure loader 10 via gas channels 14 between the gas pistons 4 and the barrel 2 ,

The gas channels 14 can be part of the gas piston housing at a nearby the weapon housing gas sampling 3 be. 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).

The operation is as follows:
After the firing of ammunition 11 In the short term, propellants form via the bores or gas channels 14 in the piston guides of the gas piston 4 penetration. These gases act on the gas pistons 4 which in turn are moved backwards. As a result, also the adjacent closing spring sleeves 6 moved backwards. This will be the shutter 7 led backwards. Here are the closing springs 5 compressed and tense. The lock 7 becomes a new ammunition in its rear position 11 submitted. By relaxing the closing springs 5 become the closing spring sleeves 6 and with it the closure 7 moved forward, the ammunition 11 the patron chamber 8th of the barrel 2 fed. At the same time the gas pistons 4 transferred to the starting position.

Because of the gas piston housing 3 Part of the barrel 2 or as an independent part on the weapon barrel 2 is fixed, can now longer closing springs 5 as well as closing spring sleeves 6 be involved.
