Abstract

Device for controlling the inertia of the gases applicable to the muzzle of firearms, composed of a generally annular body provided with a mouth plate and a portion forming a recoil plate with a concave curved surface facing the mouth; a passage through said body axially aligned with the barrel of the firearm for the passage of the bullet through it, said step being determined by a posterior cylindrical bore made in said portion of the mouth plate and arranged for its attachment to the end of the barrel. Weapon corresponding to the mouth, and another drill substantially cylindrical practiced in the backing plate and having such dimensions that it is closed when the bullet is in its interior, preventing the passage of gases through it; a conical chamber located between said portions of the mouth plate and the backing plate, whose axis is in extension with the axis of the mouth, increasing the section of said conical chamber from the mouth plate to the backing plate, and said chamber being closed in its front portion and provided with a peripheral port adjacent to the mouth plate and extending through the wall of said chamber, so that the gases expelled by the mouth move inside the chamber. The chamber beyond the bullet collides with the concave surface of the recoil plate in the closed portion of the chamber and is deflected back and forth in the direction of the mouth and the port as the bullet passes through the bore of the chamber. Recoil plate, dissipating the kinetic energy of the gases before they pass to the outside through the port. (Machine-translation by Google Translate, not legally binding)
