Reverse flow firearm suppressor

Abstract

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.

         5 . The firearm suppressor of  claim 1 , where at least one of the stackable flow directors is configured to direct a flow of gasses in a helical direction towards the longitudinal axis. 
     
     
         6 . The firearm suppressor of  claim 5 , where at least one of the stackable flow directors comprises a plurality of vanes configured to direct a flow of gasses in one of either a helically clockwise direction or a helically counterclockwise direction. 
     
     
         7 . The firearm suppressor of  claim 6 , where a one of the plurality of stackable flow directors includes helically clockwise oriented vanes and is positioned adjacent a one of the plurality of stackable flow directors that includes helically counterclockwise oriented vanes. 
     
     
         8 . The firearm suppressor of  claim 1 , where the outer cylinder is configured to couple with a muzzle of a firearm. 
     
     
         9 . The firearm suppressor of  claim 1 , further comprising an inner cylinder having an inner chamber disposed at least partially within the outer cylinder. 
     
     
         10 . The firearm suppressor of  claim 9 , where the inner cylinder is disposed between the outer cylinder and the plurality of stackable flow directors. 
     
     
         11 . A firearm comprising:
 a suppressor coupled to a muzzle of the firearm, the suppressor comprising:
 an outer cylinder defining a longitudinal axis; 
   a plurality of stackable flow directors disposed within the outer cylinder, where a first flow director of the plurality of stackable flow directors is configured to direct a flow of gasses away from the longitudinal axis and a second flow director of the plurality of stackable flow directors is configured to direct the flow of gasses towards the longitudinal axis.   
     
     
         12 . The firearm of  claim 11 , where the plurality of stackable flow directors are configured to create one or more non-linear gas flow paths that are off-axis with respect to the longitudinal axis. 
     
     
         13 . The firearm of  claim 11 , where at least one of the non-linear gas flow paths is sinuous. 
     
     
         14 . The firearm of  claim 11 , where at least one of the stackable flow directors is configured to direct a flow of gasses in a helical direction away from the longitudinal axis. 
     
     
         15 . The firearm of  claim 11 , where at least one of the stackable flow directors is configured to direct a flow of gasses in a helical direction towards the longitudinal axis. 
     
     
         16 . The firearm of  claim 15 , where at least one of the stackable flow directors comprises a plurality of vanes configured to direct a flow of gasses in one of either a helically clockwise direction or a helically counterclockwise direction. 
     
     
         17 . The firearm of  claim 16 , where a one of the plurality of stackable flow directors includes helically clockwise oriented vanes and is positioned adjacent a one of the plurality of stackable flow directors that includes helically counterclockwise oriented vanes. 
     
     
         18 . The firearm of  claim 11 , where one of either the inner cylinder or the outer cylinder is configured to couple with a muzzle of a firearm. 
     
     
         19 . A firearm suppressor comprising:
 an outer cylinder defining a longitudinal axis; and   a plurality of stackable flow directors disposed within the outer cylinder that create a sinuous flow path, where a first flow director of the plurality of stackable flow directors is configured to direct a flow of gasses along the sinuous flow path in a direction away from the longitudinal axis, and a second flow director of the plurality of stackable flow directors is configured to direct the flow of gasses along the sinuous flow path in a second direction towards the longitudinal axis.
