Patent attributes
A dynamic sealing chamber magazine for an air gun carries multiple projectiles for the air gun and sequentially places each projectile in line with the bore of the gun while serving as a chamber for the projectile and gun. Each chamber of the magazine is configured to temporarily seal to an air orifice and barrel bore of the air gun upon firing. Each chamber includes a hole and two tubular sleeves therein. A pressurized gas released into a chamber when the chamber is aligned with the air orifice and barrel bore and the gun is fired pushes the sleeves apart from inside the chamber and compresses the sleeves into sealing engagement with opposing breech surfaces of the gun surrounding the air orifice and barrel bore. The sleeves decompress, unseal, and retract to a static position when the gas pressure decreases below the elastic potential energy of the sleeves.
