Reverse flow firearm suppressor
An apparatus is disclosed for a firearm suppressor. In certain examples, the firearm suppressor includes an outer cylinder defining a longitudinal axis, and an inner cylinder having an inner chamber, where the inner cylinder is disposed at least partially within the outer tube and defines an outer chamber with the outer cylinder, where the outer chamber is disposed between an inner surface of the outer cylinder and an outer surface of the inner cylinder. The suppressor also includes a reversing baffle disposed at one end of the inner cylinder and configured to reverse a flow of gasses from the inner chamber and direct the gasses into the outer chamber, and at least one reverse flow pathway comprising a reverse section and a forward section, and where the at least one reverse flow pathway fluidly couples the inner chamber with an end cap.
1. A firearm suppressor comprising:
an outer cylinder defining a longitudinal axis;
an inner cylinder having an inner chamber, where the inner cylinder is disposed at least partially within the outer cylinder and defines an outer chamber with the outer cylinder, where the outer chamber is disposed between an inner surface of the outer cylinder and an outer surface of the inner cylinder;
a coupling mechanism configured to attach the firearm suppressor to a muzzle of a firearm;
a reversing baffle disposed at one end of the inner cylinder that is opposite the coupling mechanism, and configured to reverse a flow of gasses from the inner chamber and direct the gasses into the outer chamber; and
at least one reverse flow pathway disposed within the outer chamber and comprising a reverse section and a forward section, and where the at least one reverse flow pathway fluidly couples the inner chamber with an end cap.
2. The firearm suppressor of claim 1 , where the at least one reverse flow pathway is defined by the outer surface of the inner cylinder, the inner surface of the outer cylinder, and a plurality of ridges disposed between the outer cylinder and the inner cylinder.
3. The firearm suppressor of claim 2 , where the at least one reverse flow pathway comprises at least 4 reverse flow pathways of equal circumferential arc length, and where each of the at least 4 reverse flow pathways has a unique longitudinal length.
4. The firearm suppressor of claim 3 , where each of the at least 4 reverse flow pathways is fluidly independent from each other.
5. The firearm suppressor of claim 2 , where reverse section is substantially linear and directs the flow of gasses in a direction substantially parallel with a bore axis.
6. The firearm suppressor of claim 2 , where the forward section is non-linear and is configured to direct the flow of gasses in at least a first off-axis direction and a second off-axis direction with respect to the bore axis.
7. The firearm suppressor of claim 1 , where the inner cylinder is configured to couple with a muzzle of a firearm.
8. The firearm suppressor of claim 1 , further comprising a removable flow director disposed within the inner cylinder, where the flow director comprises a plurality of vanes configured to direct the flow of gasses in one of either a clockwise or a counterclockwise direction.
9. The firearm suppressor of claim 8 , where the flow director comprises a plurality of flow directors, and where the plurality of flow directors includes at least one flow director having clockwise oriented vanes positioned adjacent a flow director having counterclockwise oriented vanes.
10. The firearm suppressor of claim 1 , where the reversing baffle comprises a plurality of lobes having a concave surface configured for redirecting the flow of gasses.
11. A firearm comprising:
a suppressor coupled to a muzzle of the firearm at a coupling mechanism, the suppressor comprising:
an outer cylinder defining a longitudinal axis;
an inner cylinder having an inner chamber, where the inner cylinder is disposed at least partially within the outer cylinder and defines an outer chamber with the outer cylinder, where the outer chamber is disposed between an inner surface of the outer cylinder and an outer surface of the inner cylinder;
a reversing baffle disposed at one end of the inner cylinder that is opposite the coupling mechanism, and configured to reverse a flow of gasses from the inner chamber and direct the gasses into the outer chamber; and
at least one reverse flow pathway disposed within the outer chamber and comprising a reverse section and a forward section, and where the at least one reverse flow pathway fluidly couples the inner chamber with an end cap.
12. The firearm of claim 11 , where the at least one reverse flow pathway is defined by the outer surface of the inner cylinder, the inner surface of the outer cylinder, and a plurality of ridges disposed between the outer cylinder and the inner cylinder.
13. The firearm of claim 12 , where the at least one reverse flow pathway comprises at least 4 reverse flow pathways of equal circumferential arc length, and where each of the at least 4 reverse flow pathways has a unique longitudinal length.
