This enables the manufacturer to easily set the weapon to comply with regulations for different customers. The settings are changed simply by replacing one or two valve elements. The gas charge is applied to the projectile by an impulse control. The slugs are held in a revolver magazine with shaped fingers on the loading side to hold the slugs and with an outer O-ring to further secure the magazine. The magazine holds a range of slug lengths without the front ends of the slugs protruding from the magazine.

Description

The present invention relates to a compressed gas powered firearm according to the preambles of claims 1, 8 and 14. The present invention further relates to a plurality of components for the manufacture of a firearm according to the preamble of claim 21.

Compressed gas operated firearms of the aforementioned type are known. With regard to the kinetic energy of the projectile leaving the firearm, there are different conditions in different countries. For example, the kinetic energy in Germany may not exceed 7.5 J. In other countries, other regulations apply, so that there projectiles can have a kinetic energy of up to 16 J. It is operated in the prior art, a relatively large effort to construct compressed gas operated firearms with different kinetic energy of the projectiles shot down.

From the DE 101 16 010 A1 is known a compressed gas powered firearm, in which a detachable from the firearm receptacle for two compressed gas cartridges is provided, this recording can be attached to the firearm with connecting means. In the firearm known from the aforementioned prior art, the two compressed gas cartridges are pressed into the receptacle via a clamping device, which is provided with a rotatable handle, in such a way that the pressurized gas cartridges are pierced so that pressurized gas can escape. This clamping device is designed comparatively expensive.

There are also known gas-powered firearms, in which rotatable drums are provided for receiving projectiles. The projectiles are usually formed as so-called diabolos and have a longitudinally centered Constriction on. In most cases, the drums comprise a circumferential O-ring, which projects into the individual holes for receiving the projectiles in such a way that the diabolos are held by the O-ring in the region of their constrictions. A disadvantage of the known from the prior art firearms proves to be the fact that in market on the market different lengths of diabolos are so long that they partially protrude from the drum when they are held by the aforementioned O-ring.

The problem underlying the present invention is the creation of a firearm according to the preamble of claim 1, which can be easily changed to have different kinetic energies of the projectile shot down. Furthermore, the present invention is based on the problem to produce a compressed gas powered firearm according to the preamble of claim 8, in which also different lengths projectiles can be held in the holes of the drum without the projectiles protrude from the drum. Furthermore, the present invention is based on the problem to provide a firearm according to the preamble of claim 14, wherein the compressed gas cartridges can be opened more easily. Furthermore, a plurality of components is to be specified, which is suitable for the production of a firearm according to the preamble of claim 1.

These problems are solved with respect to the firearm by the claims 1, 8 and 14 and with respect to the plurality of components by the claim 21. The subclaims relate to preferred embodiments of the invention.

According to claim 1 it is provided that the valve means are designed such that by replacing at least a first part against at least a second part of the valve means per shot for the acceleration of the projectile available amount of compressed gas and / or for the application of the projectile available Standing pressure of the compressed gas can be changed. In this way, by changing the at least one first part against the at least one second part, the kinetic energy of the projectile accelerated by the compressed gas can be changed. For example, when the first part is used, the kinetic energy of the projectile can be significantly greater than 7.5 J, whereas when the second part is used, the kinetic energy is less than 7.5 J.

There is the possibility that the first and the second part of the valve means are a first and a second valve tappet. Such valve tappets are relatively easy to install in the valve means, so that the replacement of the first part against the second part can be realized with the simplest means.

There is the possibility that the first valve tappet, at least in sections, has a greater length than the second valve tappet.

In particular, it may be provided that the valve tappet for triggering a shot can be acted upon with a pulse, such that the valve stem is slightly moved relative to other parts of the valve means, whereby the valve means are opened by this movement at least partially and for a period of time and Projectile is pressurized with compressed gas. If a longer valve lifter is used in this case, the valve means are opened further and also opened for a longer period, so that a larger amount of compressed gas emerges. Accordingly, when using a shorter valve lifter, a smaller amount of pressurized gas will be available for accelerating the projectile.

There is also the possibility that the valve means comprise a spring against the force of the valve stem can be moved to trigger a shot. By the spring, a restoring force is generated which, contrary to the pulse which can be imparted to the valve tappet for opening the valve, the valve stem can move back to its original position.

According to claim 8 it is provided that the drum has at one of its axial end faces a plurality of recesses which at least partially surround the ends of each of the bores. Through the recesses, the impressions of the projectiles can be facilitated in the bores of the drum so that the projectile can be further pressed in the axial direction of the drum in the bore. In this way, an O-ring used, for example, for mounting can be further removed from the end face on which the recesses are provided, so that even longer projectiles can be held in the drum in such a way that they do not abut on the end face provided with the recesses sticking out of the drum.

It can be provided that each of the recesses has the shape of a spherical segment. In particular, in each case a recess can surround the axial end of one of the holes substantially symmetrically. In this way, the introduction of the projectile is facilitated in the recess provided with the end of the bore.

As in the prior art, it can be provided that a holding means for holding a projectile in the bore is provided in or on each of the bores. These holding means may be formed as projecting into the respective bore O-ring, wherein the O-ring projects radially, in particular from the outside into the respective bore.

According to claim 14 it is provided that the connecting means and / or the receptacle are designed such that the at least one compressed gas cartridge for the discharge of compressed gas is opened by the connection of the recording with the firearm. In this way, can be dispensed with the separate piercing of the compressed gas cartridges. Rather, this is achieved automatically by the connection of the recording with the firearm.

There is the possibility that the receptacle has at least two compressed gas cartridges, both of which can be opened by connecting the receptacle with the firearm. For example, the receptacle may be designed such that after the opening of the at least two compressed gas cartridges, the pressurized gas emerging from them at least partially flows around the compressed gas cartridges. The receptacle can be elongate and the two compressed gas cartridges can be arranged one behind the other in the longitudinal direction of the receptacle. In particular, the openings of the compressed gas cartridges may each face the ends of the receptacle. In this way, the opening of the compressed gas cartridges when connecting the recording with the firearm can be realized with simple means.

Preferably, the receptacle is designed such that after removal of the receptacle from the firearm, the receptacle is sealed so that no compressed gas exits the receptacle.

The compressed gas may be carbon dioxide, so that commercial carbon dioxide cartridges may be used.

According to claim 21 it is provided that the components comprise at least a first part and at least a second part, which can be used optionally for the assembly of the valve means and differ in that when using the at least one first part for the assembly of the valve means the pro Shot for the acceleration of the projectile available amount of compressed gas and / or the pressure available for the application of the projectile pressure of the compressed gas is greater than when using the at least one second part. Here, too, it can be provided that the at least one first and the at least one second part of the valve means are a first and a second valve tappet. In particular, the first valve tappet may have, at least in sections, greater length than the second valve tappet.

As can be seen from FIGS. 1 a and 1 b, a firearm according to the invention comprises a barrel 1, at the rear end of which a rotatable drum 2 is arranged, in which projectiles 3 can be held. The firearm further comprises a receptacle 4 (see FIGS. 2 and 5a) in which two compressed gas cartridges 5, 6 are arranged, as well as connecting means 7 for connecting receptacle 4 to the firearm.

Through the connecting means 7, gas flowing out of the compressed gas cartridges 5, 6, such as CO ₂ , can reach valve means 8. The valve means 8 can be seen in FIG. 5a and in FIG. When actuated valve means 8, the pressurized gas can pass through a channel 9 behind a running projectile 10, whereby the projectile 10 in the run is accelerated to the right in Fig. 2 from the run out. The projectile 10 arrives at the firing position shown in FIG. 2 by a slide, not shown, which can convey the projectile out of the drum 2 into the firing position.

The valve means 8 can be actuated upon actuation of a trigger 11 by a hammer 12. The hammer 12 can be seen in FIG. 2 and has a pin 13 on its right side in FIG. Upon actuation of the trigger 11, the hammer 12 moves to the right in Fig. 2, wherein the pin 13 is moved through a recess to the right until it meets a valve stem 14 of the valve means 8 and this also moves to the right in Fig. 2 , The pin 13 transmits a pulse on the valve stem 14, so that it moves against the force of a spring 15 also included in the valve means 8 to the right in Fig. 2 and according to the transmitted pulse after a short time by the spring 15 again is moved back to the left in Fig. 2. The pin 13 remains in the position in which he has transmitted the impulse to the valve stem 14. This is achieved in that the right in Fig. 2 end face of the hammering piece 12 abuts against a stop 16.

The valve stem 14 has, on its side located in the interior of the valve on a flange-like surface 17 which seals in the closed state of the system (see Fig. 5a) against an O-ring 18. By moving the valve stem 14 to the right in Fig. 2, the flange-like surface 17 is released from the O-ring 18, so that pressurized gas from the connecting means 7 can pass through the valve into the channel 9. After a short time, the spring 15 pushes the valve stem back to the left in Fig. 2, so that the flange-like surface 17 again seals against the O-ring 18 and no compressed gas can get into the channel 9 more.

According to the invention, it is provided that the valve tappet 14 can be exchanged for another, not shown, valve tappet having a different length, in particular a different length of the portion between the flange-like portion 17 and the left in Fig. 2, the pin 13 facing the end. When the valve stem as a whole or when the piece between the left front end and the flange-like portion 17 is longer than in the embodiment shown in Fig. 2, is transmitted by momentum transfer from the pin 13 to the valve stem of the flange-like portion 17 further into the valve means eighth pressed so that the total opening time of the valve means 8 is increased relative to the embodiment shown in Fig. 2. Furthermore, a larger opening of the valve means is achieved even in the maximum pushed to the right position of the valve stem (see Fig. 2). Due to this larger opening or due to this larger opening time is more pressurized gas flow into the channel 9, so that the projectile 10 located in the run can be accelerated out of the barrel by a larger amount of compressed gas and / or by a greater pressure. As a result, a larger momentum is imparted to the projectile in the case of a longer valve stem or valve stem having a longer effective portion.

From Fig. 3, Fig. 4a, Fig. 4b, Fig. 5a and Fig. 5b, the receptacle 4 is apparent sichtsichtlicht. In particular, Fig. 3 shows that in the receptacle 4 two pressurized gas cartridges 5, 6 are arranged one behind the other, such that their bottoms abut each other. The tips 19, 20 of the compressed gas cartridges 5, 6 are directed towards the outer ends of the receptacle 4 out. The receptacle 4 has Anstechnadeln 21, 22 which abut in the position shown in Fig. 4a and Fig. 4b at the tips 19, 20, but these have not pierced.

On the side facing the connecting means 7, the receptacle 4 has a movably mounted connection part 23. This connection part 23 has a neck 24 with an O-ring 25 surrounding the neck. In the position shown in Fig. 4a of the neck 24 surrounding the O-ring 25 seals against a constriction 26 of the receptacle 4 from.

5a and 5b show the position of the receptacle 4 associated with the firearms. In this position the connecting means 7 push the connecting part 23 to the right in FIG. 5a, so that the neck 24 is pushed so far to the right in FIG. 5a in that the O-ring 25 no longer seals against the constriction 26. In this way, compressed gas can flow from the receptacle 4 through the connecting means 7 into the valve means 8 past the neck 24 through the constriction 26. The movement of the connection part 23 to the right in Fig. 5a and Fig. 5b has led to the needles 21, 22, the tips 19, 20 of the compressed gas cartridges 5, 6 have pierced. This was effected inter alia by the right-hand pressurized gas cartridge 6 being moved to the right against the piercing needle 22 and at the same time the connecting part 23, which carries the piercing needle 21 at its right end, being pressed against the left-hand pressurized gas cartridge 5.

The pressurized gas flowing out of the right-hand pressurized gas cartridge 6 can pass via the injection needle 22 into the space 27 surrounding the pressurized gas cartridges 5, 6 and flow past the pressurized gas cartridges 5, 6 and into the space 28 of the receptacle 4 surrounding the connecting part 23. The pressure gas emerging from the left-hand pressurized gas cartridge 5 can pass directly through the piercing needle 21 into this space 28. From the space surrounding the connection part 23 28, the compressed gas can pass through the constriction 26 and the connecting means 7 in the valve means 8. From Fig. 5a, an O-ring 29 can be seen, which seals the left in Fig. 5a end of the receptacle 4 against the provided in the region of the connecting means 7 opening of the firearm.

When the receptacle 4 is pulled out of the connection means, the connection part 23 will also move to the left through the pressure built up in the space 27 by the pressurized gas until the position shown in Figs. 4a and 4b is reached, in which the neck with the O-ring 25 seals against the constriction 26. In this state, although the compressed gas cartridges 5, 6 are then opened. However, the compressed gas can not escape from the receptacle 4.

From FIG. 6 and FIG. 7, the drum 2 of a firearm according to the invention can be seen. The drum 2 has a plurality of bores 30 concentric about the axis of the drum are arranged. In the illustrated embodiment, eight holes 30 are provided. As can be seen in FIG. 7, projectiles 3 can be introduced into the bores 30. The drum 2 further has at the radially outer edges of the bores 30 a circumferential groove 31 in which an O-ring 32 is arranged. From FIG. 6 and FIG. 7 it can be seen that the O-ring 32 protrudes radially into the individual holes 30 from the outside.

The projectiles 3 are provided as Diabolos with a constriction. The o-ring 32 protrudes from outside into these constrictions, so that diabolos are held by the o-ring 32 in the bores 30. The drums continue to have on their left in Fig. 7 axial end side recesses 33 which surround the front ends of the bores 30. The recesses 33 are formed in the illustrated embodiment as spherical segments which surround the holes rotationally symmetrical.

Due to the recesses 33, the projectiles 3 from the left in Fig. 7 slightly deeper into the holes 30, that is, a little further to the right into the holes 30 are inserted. For this reason, in the drum of the present invention, the O-ring 32 can be placed a little further to the right in Fig. 7 than is the case with conventional drums. Therefore, even very long projectiles 3 can be introduced into the bores 30, without they protrude to the left in Fig. 7 from the drum 2.
