Abstract
The present disclosure provides a firearm suppressor comprising a proximal end configured to attach to a firearm barrel, a distal end, and a housing disposed between the proximal and distal ends. The housing may include a gas recirculation system that includes return tubes configured to redirect gas from the central chamber to the peripheral chamber, and injection tubes in fluid communication with the peripheral chamber and a receiving baffle to extend gas dwell time. The housing may include, in combination or separately, a helical path assembly. Other innovative aspects, such as an identification plate system, baffle features, support lattice, etc., are also disclosed.
Claims23
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:
- an inner tube separating a central chamber from a peripheral chamber;
- a terminal baffle adjoining both the inner tube and the distal end, the terminal baffle comprising a neck;
- and
- a bore extending through the proximal end, the distal end, and the housing;
- and
- a plurality of return tubes formed on the terminal baffle and configured to redirect gas between the central chamber and the peripheral chamber, wherein the plurality of return tubes is in fluid communication with the peripheral chamber,
- wherein the plurality of return tubes extends gas dwell time within the firearm suppressor.
A method for suppressing sound in a firearm, the method comprising:
- attaching a suppressor to a firearm barrel at a proximal end of the suppressor;
- firing a projectile through a bore extending through the proximal end, a distal end, and a housing of the suppressor;
- separating gas flow into a central chamber and a peripheral chamber using an inner tube disposed within the housing;
- redirecting gas between the central chamber and the peripheral chamber using a plurality of return tubes formed on a terminal baffle adjoining both the inner tube and the distal end;
- and
- extending gas dwell time within the suppressor by recirculating gas through the plurality of return tubes in fluid communication with the peripheral chamber.
