Compressed gas-driven firearm

Abstract

A compressed-gas-operated firearm, comprising a reservoir for compressed gas; valve means ( 8 ) for supplying the compressed gas from the reservoir to a projectile ( 10 ) to which the compressed gas is to be applied, in which case the valve means ( 8 ) can have an impulse applied to it, at least in places, for firing a shot; in which case the valve means ( 8 ) are designed such that, by replacement of at least one first part by at least one second part of the valve means ( 8 ), the amount of compressed gas which is available for the acceleration of the projectile ( 10 ) per shot and/or the pressure of the compressed gas which is available for application to the projectile ( 10 ) can be varied.

       28 : The firearm according to  claim 25 , wherein said valve configuration includes a spring and said valve stem is moved against a force of said spring in order to fire a shot.  
   
   
       29 : The firearm according to  claim 25 , which comprises a striking lever movably disposed for firing a shot and for applying a pulse to said valve stem by a movement thereof.  
   
   
       30 : The firearm according to  claim 29 , wherein said striking lever includes a pin disposed to strike said valve stem and to transmit a pulse to said valve stem in order to fire a shot.  
   
   
       31 : The firearm according to  claim 24 , wherein the compressed gas is carbon dioxide.  
   
   
       32 : A compressed-gas-operated firearm, comprising: 
 a drum rotatably mounted about an axis and configured to hold a plurality of projectiles;    said drum having a plurality of holes formed therein extending in an axial direction and configured to receive therein one projectile each; and    said drum having an axial end face formed with a plurality of cutouts, with each of said cutouts at least partially surrounding an end of a respective one of said holes.    
   
   
       33 : The firearm according to  claim 32 , wherein each of said cutouts is in a form of a spherical segment.  
   
   
       34 : The firearm according to  claim 32 , wherein one respective said cutout surrounds an axial end of one of said holes substantially symmetrically.  
   
   
       35 : The firearm according to  claim 32 , which comprises holding means disposed in or on each of said holes for holding a projectile in the respective said hole.  
   
   
       36 : The firearm according to  claim 35 , wherein said holding means comprise an O-ring projecting into the respective said hole.  
   
   
       37 : The firearm according to  claim 36 , wherein said O-ring projects radially into the respective said hole.  
   
   
       38 : The firearm according to  claim 36 , wherein said O-ring projections radially from outside into the respective said hole.  
   
   
       39 : A compressed-gas-operated firearm, comprising: 
 a holder, removably mounted to the firearm, for holding at least one compressed-gas cartridge;    a connecting device for connecting said holder to the firearm; and    wherein at least one of said connecting device and said holder is configured to open said at least one compressed-gas cartridge for the compressed gas to emerge when the holder is connected to the firearm.    
   
   
       40 : The firearm according to  claim 39 , wherein said holder carries at least two compressed-gas cartridges, and both said cartridges are opened by connecting said holder to the firearm.  
   
   
       41 : The firearm according to  claim 40 , wherein said holder is configured such that, after said at least two compressed-gas cartridges are opened, the compressed gas emerges therefrom flows around said compressed-gas cartridges, at least in sections.  
   
   
       42 : The firearm according to  claim 40 , wherein said holder is an elongated holder, and said two compressed-gas cartridges are disposed one behind another in a longitudinal direction of said elongated holder.  
   
   
       43 : The firearm according to  claim 42 , wherein each of said compressed-gas cartridges has an opening facing a respective end of said holder.  
   
   
       44 : The firearm according to  claim 39 , wherein said holder is configured such that, after removal of said holder from the firearm, said holder is sealed to prevent compressed gas from emerging from said holder.  
   
   
       45 : The firearm according to  claim 39 , wherein said compressed gas-cartridges are charged with carbon dioxide.  
   
   
       46 : A plurality of components for the manufacture of a compressed-gas-operated firearm according to  claim 24 , the components comprising:
