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 15):
A flash suppressor assembly comprising:\n a housing including an outer sleeve having a first end and a second end, a base cap, and an end cap, wherein the first end of the outer sleeve is operatively connected to the base cap and the second end of the outer sleeve is operatively connected to the end cap, the end cap including a plurality of gas vents, 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 base cap and a second end operatively connected to the end cap, the tubular burn chamber including an internal portion; a receiver detachably secured to the base cap, 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 end cap, 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 pre-processing 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 pre-processing 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 first set of chambers comprising a first accelerating chamber in fluid communication with a first expanding burn chamber, the volume area of the first accelerating chamber being less than a volume area of the pre-processing chamber such that the combustion gas flowing from the pre-processing chamber to the first accelerating chamber is accelerated by compression in the first accelerating chamber, the volume area of the first expanding burn chamber being greater than the volume area of the first accelerating chamber such that the accelerated combustion gas flowing from the first accelerating chamber to the first expanded burn chamber is expanded in the first expanded burn chamber and burns with an intermixing of the combustion gas with oxygen, the first expanding burn chamber including a rippled outer surface on the portion of the burn tube disposed in the first expanded burn chamber to facilitate intermixing of the oxygen with the combustion gas to enhance burning thereof; a second set of chambers comprising a second accelerating chamber in fluid communication with a second expanding burn chamber, the second accelerating chamber being in fluid communication with the first expanded burn chamber, the volume area of the second accelerating chamber being less than a volume area of the first expanded burn chamber such that the burned combustion gas flowing from the first expanded burn chamber to the second accelerating chamber is accelerated by compression in the second accelerating chamber, the volume area of the second expanding burn chamber being greater than the volume area of the second accelerating chamber such that the accelerated burned combustion gas flowing from the second accelerating chamber to the second expanded burn chamber is expanded in the second expanded burn chamber and further burns with an intermixing of the burned combustion gas with oxygen, the second expanding burn chamber including a rippled outer surface on the portion of the burn tube disposed in the second expanded burn chamber to facilitate intermixing of the oxygen with the burned combustion gas to enhance burning thereof; a cooling chamber in fluid communication with the second expanded burn chamber, the cooling chamber including a spiral threaded profile in the inner wall surface portion of the tubular burn chamber disposed in the cooling chamber, the spiral threaded profile causing the burning gas to spin to facilitate burning and cooling of the burned gas as the burned gas flows through the cooling chamber; a slowing chamber in fluid communication with the cooling chamber, the slowing chamber configured to slow a flow rate of the cooled gas before the cooled gas flows through the plurality of gas vents in the end cap to the exterior of the flash suppressor assembly.
