US12669303 - Firearm suppressor with gas recirculation and modular components

The patent describes a firearm suppressor that features a gas recirculation system designed to enhance gas dwell time through a series of return and injection tubes. It includes a modular housing with multiple baffles and chambers to effectively manage and redirect gas flow, improving overall suppressor performance.
Claim 1
1 . A gas recirculation system for a firearm suppressor comprising: a proximal end configured to attach to a firearm barrel; a distal end; a housing disposed between the proximal end and the distal end, the housing comprising a plurality of components comprising: a blast chamber adjacent to the proximal end; a receiving baffle disposed near the proximal end, the receiving baffle comprising: a plurality of ports formed through the receiving baffle; an inner tube adjoining the receiving baffle, wherein the inner tube separates a central chamber from a peripheral chamber; and a terminal baffle adjoining both the inner tube and the distal end, the terminal baffle comprising: a neck oppositely disposed from the distal end; and at least a first intermediary baffle disposed between the receiving baffle and the terminal baffle in the central chamber; a bore piercing the proximal end, the distal end, and the plurality of components of the housing; and a gas recirculation system comprising: a plurality of return tubes configured to redirect gas between the central chamber and the peripheral chamber, wherein the plurality of return tubes are: formed on the terminal baffle; and in fluid communication with the peripheral chamber; and a plurality of injection tubes in fluid communication with the peripheral chamber and the receiving baffle, wherein the gas recirculation system directs gas at the terminal baffle and conveys the gas to or from the peripheral chamber via the plurality of return tubes and ingests or releases the gas to the receiving baffle via the plurality of injection tubes to extend gas dwell time within the firearm suppressor. a proximal end configured to attach to a firearm barrel; a distal end; a housing disposed between the proximal end and the distal end, the housing comprising a plurality of components comprising: a blast chamber adjacent to the proximal end; a receiving baffle disposed near the proximal end, the receiving baffle comprising: a plurality of ports formed through the receiving baffle; an inner tube adjoining the receiving baffle, wherein the inner tube separates a central chamber from a peripheral chamber; and a terminal baffle adjoining both the inner tube and the distal end, the terminal baffle comprising: a neck oppositely disposed from the distal end; and at least a first intermediary baffle disposed between the receiving baffle and the terminal baffle in the central chamber; a blast chamber adjacent to the proximal end; a receiving baffle disposed near the proximal end, the receiving baffle comprising: a plurality of ports formed through the receiving baffle; a plurality of ports formed through the receiving baffle; an inner tube adjoining the receiving baffle, wherein the inner tube separates a central chamber from a peripheral chamber; and a terminal baffle adjoining both the inner tube and the distal end, the terminal baffle comprising: a neck oppositely disposed from the distal end; and at least a first intermediary baffle disposed between the receiving baffle and the terminal baffle in the central chamber; a neck oppositely disposed from the distal end; and at least a first intermediary baffle disposed between the receiving baffle and the terminal baffle in the central chamber; a bore piercing the proximal end, the distal end, and the plurality of components of the housing; and a gas recirculation system comprising: a plurality of return tubes configured to redirect gas between the central chamber and the peripheral chamber, wherein the plurality of return tubes are: formed on the terminal baffle; and in fluid communication with the peripheral chamber; and a plurality of injection tubes in fluid communication with the peripheral chamber and the receiving baffle, wherein the gas recirculation system directs gas at the terminal baffle and conveys the gas to or from the peripheral chamber via the plurality of return tubes and ingests or releases the gas to the receiving baffle via the plurality of injection tubes to extend gas dwell time within the firearm suppressor. a plurality of return tubes configured to redirect gas between the central chamber and the peripheral chamber, wherein the plurality of return tubes are: formed on the terminal baffle; and in fluid communication with the peripheral chamber; and formed on the terminal baffle; and in fluid communication with the peripheral chamber; and a plurality of injection tubes in fluid communication with the peripheral chamber and the receiving baffle, wherein the gas recirculation system directs gas at the terminal baffle and conveys the gas to or from the peripheral chamber via the plurality of return tubes and ingests or releases the gas to the receiving baffle via the plurality of injection tubes to extend gas dwell time within the firearm suppressor.
