Patent attributes
Methods and systems for limiting the sudden expansion of propellant gasses, products of combustion when firing a gun, exiting a barrel of a gun, which otherwise would result in a very loud noise, sharp “recoil” of the gun, and a pronounced “muzzle flash” if released unrestricted. By utilizing two or more completely segregated, or partially segregated, expansion chambers, the gasses can be allowed to sequentially expand and cool under tightly controlled conditions governed by the size and location of holes, or passageways, in the barrel which communicate with the interior of the expansion tube that encompasses the barrel. The expanding gasses are further controlled by the locations and volumes of each segregated expansion chamber, and holes in the structural vertical and horizontal bulkheads of the expansion tube, which can “steer” the gasses in order to achieve easy expansion as well as gas flow disruption goals by design.
