It is well known that when a projectile is fired from a barrel, it does not matter whether the barrel is subject to recoil or is designed without recoil - at the point in time at which the floor of the floor passes the muzzle, a considerable amount Bang up. This significant bang due to the sudden expansion of the propellant charge Compressed gases inr.Free due int, represents a great physical and psychological strain on the operating personnel, especially when it is relatively great Projectiles from a shouldered barrel to be launched. This is for example the case of the Panzerfaust designated firearm is the case,

To avoid the health hazard for the operating personnel Sometimes even life-threatening bangs are a large number of launch tubes of the type mentioned at the beginning Equipped with silencers. In the absence of better solutions than mufflers mainly found to this day rigidly designed and subdivided into several expansion chambers by baffles, check valves or the like Container usage. The containers, which are adapted in terms of volume to the respective quantities of compressed gas, the expansion chambers of which open out into the open through small cross-section holes, v / ground in the case of recoil-prone launch tubes the barrel muzzle, in the case of recoil-free launching tubes in front of the barrel muzzle and the existing ones in this case, arranged rear pipe opening, wherein in each of the containers located in front of the pipe mouth a penetration ring is intended for the storeys. The compressed gases expand into these containers after the Projectiles from the assigned launch tubes first enter before they are passed through the expansion carts of the corresponding container to the outside leading holes get into the open. On the way through the expansion skimmers the pressurized gases that have flowed in will still be used

inherent energy through the baffle ©, non-return valves or the like largely destroyed.

The known silencers, which - as has been shown - ensure that the energy which is still inherent in the projectile-accelerating compressed gases of a propellant charge is gradually released after the discharge from the discharge tube
and thus prevent the occurrence of a bang, which is observed when this energy is suddenly released, are disadvantageous in many respects. Due to their complicated construction, they are relatively expensive to manufacture. In addition, as a result of the rigid design of the container walls, especially when they are designed for high performance, they have a considerable structural volume and structural weight, which is the
Transport and handling of the launch tubes that are "soundproofed" in this way, especially those designed to be portable, are made much more difficult.

The invention is therefore based on the Ausabe, an Ab-. ■ to develop a shot tube of the type mentioned at the beginning,
^which: without this requiring the known silencers, permits quiet firing of projectiles. .. ■. ". '· ·

This object is achieved according to the invention in that
while the projectile leaves the shot tube, the mouth of which is closed, the shot tube through one or more blow-out openings provided in the tube jacket and / or in the tube muzzle closure and / or through any leaks or slits between this and the tube jacket the propellant charge generates compressed gases with a significantly smaller cross-section, bsw. Overall cross-section as the caliber cross-section is connected to the outer space.

In the launch tube according to the invention, the Arrangement of a known, production-wise expensive, weight-wise; "heavy and bulky muffler the mouth of the pipe, because the closure carried out was accompanied by a considerable bang, sudden expansion of the compressed gases generated by the propellant charge after the projectile exit is already reliably avoided will. Rather, the compressed gases escape slowly through the blow-out opening or openings and / or leaks or slots.

In an embodiment of the invention, there is a space between the propellant charge and the projectile over the entire caliber cross-section Arranged of the launch tube extending piston, which separates the propellant charge from the projectile and when Aes projectile emerges from the launch tube in the area of the muzzle. This constructive measure is extremely easy to implement with only a small amount of material and results in no noticeable increase in weight to a particularly handy, soundproofed launch tube.

According to a further feature of the invention is or are the exhaust opening or openings immediately behind the collected piston arranged in the pipe jacket. she can or can also in the projectile from the propellant charge separating, serving as a pipe muzzle closure piston be arranged * in such a way that they up to Catching the piston in the area of the barrel muzzle or until it is separated from the projectile by the latter is or are. As a catching device for the piston separating the projectile from the propellant charge here, among other things, an annular shoulder that extends radially inward and is provided in the region of the pipe mouth proven.

The propellant charge 12 is both from the projectile 10, which is about a sliding ring l4 is supported and guided in the launch tube 1 is, as well as from the filling Ip made of flowable Medium through a respective piston 15 or 16 extending over the entire caliber cross section of the launch tube 1 separated. As a result of the mutual assignment of projectile 10, propellant charge 12, filling 15 and piston 15, Ιό moves When the propellant charge 12 is ignited, under the action of the compressed gases 17 generated, the one between the projectile 10 and the propellant charge 12 located piston 15 with the projectile 10 attached thereto in the direction of

The tube mouth 4 and the other piston l6 located between the propellant charge 12 and the filling Ij5 of flowable medium in the direction of the rear tube opening 5, the membrane 6 which closes the rear tube opening 5 before the ignition of the propellant charge 12 is destroyed and the flowable one Medium in finely divided form lö the launch tube 1 via the rear tube opening 5 leaves. In the present case the filling is Ij? made of flowable medium to reliably avoid recoil in terms of quantity in such a way that both pistons 15 and 16 come to rest on the ring shoulders 7 and 8 of the launch tube 1 assigned to them at the same time. At this moment, in which the bullet 10 disengages vou to-w parent piston I5 and passes through the Rohrmündunrj h, two places in the region of the front pipe end 2 disposed in the tube jacket discharge openings I9, the total cross-section is substantially smaller than the caliber cross-section of the launcher tube 1, a connection between the pressurized gas-filled pipe interior 9 and the exterior, co that the pressurized gases I7 can escape slowly, that is, without a bang.
