  • Patent number: 4756297
    Abstract: An air weapon comprising a hand grip and a generally tubular-shaped housing connected thereto having front and rear ends confining a tubular pressure chamber. The pressure chamber is of non-cylindrical configuration thereby providing a pressure chamber of increased volume over that obtainable with a cylindrically shaped chamber without detrimentally affecting the external appearance of the weapon. A cylindrical barrel for discharging a projectile from the weapon is positioned within and coaxial to the pressure chamber. A piston conforming to the configuration of the pressure chamber and adapted to move within the pressure chamber along its axis surrounds the barrel with its piston head facing the rear end of the housing. A piston spring also surrounds the barrel and is positioned against the piston head at one of its ends and against the front end of the housing at its other end.
