Abstract (en)

A gas powered gun for repeated discharge of projectiles, comprising a barrel adapted to receive a projectile from a magazine, a pressure chamber adapted to communicate with a compressed gas cartridge fitted to the gun, an open-close valve for exhausting compressed gas from said chamber to discharge a projectile in the barrel, and a hammer arranged to actuate said open-close valve. The gun comprises a chamber for collecting partly expanded compressed gas after said gas has been used to discharge said projectile, a piston arranged in a housing and being mechanically connected to said hammer, and a channel for directing said partly expanded gas into said housing, so that said gas will force said piston to move, thereby bringing said hammer to a ready-for-fire-position.
