Abstract
A gas-powered gun for discharge of projectiles, comprising a pressure chamber for holding compressed gas, a valve arranged to release compressed gas from the pressure chamber to thereby discharge a projectile provided in a barrel, and a plenum chamber in fluid connection with the pressure chamber. The plenum chamber is formed coaxially around a rear portion of the barrel.
Claims20
A gas-powered gun for discharge of projectiles, comprising:
- a barrel;
- a pressure chamber for holding compressed gas;
- a valve arranged to release compressed gas from the pressure chamber to thereby discharge a projectile provided in the barrel;
- a plenum chamber in fluid connection with the pressure chamber;
- and
- a pressure regulator providing a controlled pressure in the pressure chamber and the plenum chamber,
- wherein the plenum chamber is formed around at least a rear portion of said barrel and is formed by a sleeve surrounding the barrel, said sleeve being sealed in a front end by a front sealing and in a rear end by a rear sealing, said rear sealing formed with a passage providing a fluid connection between the plenum chamber and the pressure chamber.
