Suppressor design

Abstract

An improved design for a suppressor which suppresses sound from a gun report as well as reduces heat transference therefrom.

What is claimed is: 
     
         1 . A suppressor comprising:
 a muzzle endcap;   a muzzle end cap insulation disc;   an inner tube;   an outer tube, wherein an insulating material is located between the inner tube and the outer tube;   an inner blast baffle spacer;   a main baffle;   a main expansion chamber;   an inner tube;   an exit end cap insulation disc; and   an exit end cap.   
     
     
         2 . The suppressor of  claim 1 , wherein the insulating material comprises fibrous silica. 
     
     
         3 . The suppressor of  claim 1 , wherein the insulating material comprises a silica fiber reinforced microporous foam comprised of fumed silica, metal oxides, and reinforcement fibers. 
     
     
         4 . The suppress or  claim 3 , wherein foam is covered by a fabric comprised of the same material as the foam, wherein the fabric has a greater proportion of reinforcement fibers than the foam. 
     
     
         5 . The suppressor of  claim 1 , wherein the insulating material comprises a flexible fabric that covers a condensed powder, wherein both the flexible fabric and the condensed powder comprise alumina-magnesia-carbon flexible ceramic. 
     
     
         6 . The suppressor of  claim 1 , wherein a vacuum is formed between the inner tube and the outer tube. 
     
     
         7 . The suppressor of  claim 1 , wherein the suppressor has a diameter of substantially 2 inches. 
     
     
         8 . The suppressor of  claim 1 , wherein the muzzle end cap insulation disc, the exit end cap insulation disc and the insulating material between the inner and outer tube comprise the same insulation. 
     
     
         9 . The suppressor of  claim 1 , wherein the outer tube is covered by a carbon fiber wrap. 
     
     
         10 . A method for forming a suppressor comprising:
 forming an outer tube of the suppressor which circumferentially surrounds an interior of the suppressor;   placing a muzzle endcap on a proximal end of the suppressor, which engages the outer tube;   placing a muzzle end cap insulation disc in the interior of the suppressor positioned distally from the muzzle end cap;   placing an exit end cap on a distal end of the suppressor, which engages the outer tube;   placing an exit end cap insulation disc in the interior of the suppressor proximal to the exit end cap;   placing an insulation tube in the interior of the suppressor adjacent to the outer tube;   placing an inner tube adjacent the insulation tube in the interior of the suppressor;   forming an inner blast baffle spacer toward the proximal end of the suppressor and a main baffle toward the distal end of the suppressor, all encircled by the inner tube;   forming a main expansion chamber toward the distal end of the suppressor, wherein the main expansion chamber contains the main baffle; and   forming a bullet path extending longitudinally through the suppressor and through a body of the main baffle.   
     
     
         11 . The suppressor of  claim 10 , wherein insulating material for the muzzle end cap insulation disc, the exit end cap insulation disc, and the insulation tube comprises fibrous silica. 
     
     
         12 . The suppressor of  claim 10 , wherein insulating material for the muzzle end cap insulation disc, the exit end cap insulation disc, and the insulation tube comprises a silica fiber reinforced microporous foam comprised of fumed silica, metal oxides, and reinforcement fibers. 
     
     
         13 . The suppress or  claim 12 , wherein foam is covered by a fabric comprised of the same material as the foam, wherein the fabric has a greater proportion of reinforcement fibers than the foam. 
     
     
         14 . The suppressor of  claim 10 , wherein insulating material for the muzzle end cap insulation disc, the exit end cap insulation disc, and the insulation tube comprises a flexible fabric that covers a condensed powder, wherein both the flexible fabric and the condensed powder comprise alumina-magnesia-carbon flexible ceramic. 
     
     
         15 . The suppressor of  claim 10 , wherein a vacuum is formed between the inner tube and the outer tube. 
     
     
         16 . The suppressor of  claim 10 , wherein the suppressor has a diameter of substantially 2 inches. 
     
     
         17 . The suppressor of  claim 10 , further including covering the outer tube with a carbon fiber wrap.
