Definitions

  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • the kinetic energy of the projectile accelerated by the compressed gas can be changed.
  • 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.
  • 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.
  • the first valve tappet at least in sections, has a greater length than the second valve tappet.
  • 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.
  • valve means comprise a spring against the force of the valve stem can be moved to trigger a shot.
  • the spring 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.
  • 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.
  • 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.
  • 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.
  • each of the recesses has the shape of a spherical segment.
  • 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.
  • 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.
  • 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.
  • the receptacle has at least two compressed gas cartridges, both of which can be opened by connecting the receptacle with the firearm.
  • 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.
  • 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.
  • 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.
  • 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.
  • the at least one first and the at least one second part of the valve means are a first and a second valve tappet.
  • the first valve tappet may have, at least in sections, greater length than the second valve tappet.
  • 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.
  • valve means 8 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.
  • 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 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.
  • a flange-like surface 17 which seals in the closed state of the system (see Fig. 5a) against an O-ring 18.
  • 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.
  • 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.
  • 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).
  • 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.
