Abstract:
A flash suppressor assembly that captures, burns, and cools the combustion gases produced when a projectile, such as a bullet, is fired by a weapon. The flash suppressor assembly includes a housing with an internal space containing a tubular burn chamber disposed about a burn tube that define at least one set of an accelerated gas flow chamber, an expanded burn chamber, and an elongated cooling chamber. The outer surface profile of the burn tube includes grooves that facilitate the intermixing of oxygen with the combustion gases to enhance burning thereof.

Claim (Index 1):
A flash suppressor assembly comprising:\n a housing including a first end and a second end, the housing including an internal space; a tubular burn chamber disposed within the internal space of the housing, the tubular burn chamber having a first end operatively connected to the first end of the housing and a second end operatively connected to the second end of the housing, the tubular burn chamber including an internal portion; a receiver detachably secured at the first end of the housing, the receiver configured for detachable fixation to a barrel muzzle, the receiver including an internal bore wall defining a bore for receiving and transporting a projectile fired by a weapon, the receiver extending into the internal portion of the tubular burn chamber; a burn tube operatively positioned in axially alignment with the receiver, a first end of the burn tube operatively supported by an end of the receiver, a second end of the burn tube operatively connected to the second end of the housing, the burn tube disposed within the internal portion of the tubular burn chamber, the burn tube including an internal bore wall defining a bore for receiving and transporting the projectile; a first chamber defined by a first inner wall surface portion of the tubular burn chamber and a first outer wall surface portion of the receiver, the first chamber receiving, through one or more openings in the bore wall of the receiver, a combustion gas produced by the firing of the projectile; a second chamber defined by a second inner wall surface portion of the tubular burn chamber and a second outer wall surface portion of the receiver and a first portion of a first outer wall section of the burn tube, the volume area of the second chamber being less than a volume area of the first chamber such that the combustion gas flowing from the first chamber to the second chamber is accelerated by compression in the second chamber; a third chamber defined by a third inner wall surface portion of the tubular burn chamber and a second portion of the first outer wall section of the burn tube, the volume area of the third chamber being greater than the volume area of the second chamber such that the accelerated combustion gas flowing from the second chamber to the third chamber is expanded in the third chamber and burns with an intermixing of the combustion gas with oxygen; a fourth elongated chamber defined by a fourth inner wall surface portion of the tubular burn chamber and a second and third outer wall sections of the burn tube, the fourth inner wall surface being profiled with spiral threads, the spiral threads causing the burning gas to spin to facilitate burning and cooling of the burned gas as the burned gas flows through the fourth elongated chamber; a plurality of gas vents disposed in the second end of the housing for transmission of the burned gas from the fourth elongated chamber to the exterior of the flash suppressor assembly.
