Abstract

A suppression system adapted to receive gas from a gas operated system and route the gas through a series of multiple chambers having baffles and/or valves as well as expansion chambers where the chambers are formed around a gas projectile barrel and adapted to route the gas in a first route along the barrel in a first direction then routing the gas along the barrel in a second direction. An embodiment of the invention couples the chambers to a gas block adapted to route gas between the chambers in the first and second route as well as receive gas from the projectile barrel and route it to the gas operated system. Methods of manufacturing and methods of use are also provided.

First claim

1 . A gas operated projectile firing system suppressor comprising:
a suppressor structure having a first end and a second end on a side opposing said first end, wherein said suppressor structure comprises a first chamber and a second chamber, wherein said first chamber and said second chamber are formed on opposing sides of said suppressor structure, wherein said suppressor structure comprises a bore defined by an inner side wall of said suppressor structure, wherein said bore passes unobstructed from said first end of said suppressor structure through said second end through said suppressor structure along a first axis, wherein said bore is formed to receive and slide over a section of a barrel of said gas operated projectile firing system such that a muzzle is in proximity to said second end and said first end is positioned over said barrel away from said muzzle, wherein said suppressor structure is adapted to substantially surround a length of said barrel such that said second end of said suppressor structure is proximal to said muzzle but does not extend substantially beyond said muzzle, wherein said suppressor structure further comprises an adjustable coupling mechanism that is adapted to selectively fix said suppressor structure with respect to said barrel so as to prevent said suppressor structure from moving relative to said barrel in a first position and also permits said suppressor structure to rotate around said barrel in a second position; at least one gas intake port formed into said inner side wall, wherein said gas intake port is closer to said first end of said suppressor structure than said second end of said suppressor structure, wherein said gas intake port is adapted to convey gas from a barrel port formed in a side of said barrel to a section of said suppressor structure in proximity to said second end of said first chamber; at least one gas pass-through port formed in proximity to said first end, wherein said pass-through port is formed with a passage to convey said gas passing into said first chamber into said second chamber in proximity to said first end of said suppressor structure; and at least one exhaust port formed in a section of said second end of said suppressor structure, wherein said exhaust port is adapted to expel said gas from said second chamber and so exhaust said gas from said suppressor structure.

2 . A gas operated projectile firing system suppressor as in claim 1 , further comprising:
a first plurality of baffle walls positioned inside said first chamber, wherein said first plurality of baffle walls are oriented substantially perpendicular to a first gas path defining said gas movement through said first chamber to said at least one gas pass-through port, wherein at least one of said baffle walls are coupled at one side to one side of said first chamber that is substantially parallel to said first gas path, said first plurality of baffle walls are formed with a material that flexibly displaces or moves on when said gas moves along said first gas path and past said first plurality of baffle walls; and a second plurality of baffle walls positioned inside said second chamber, wherein said second plurality of baffle walls are oriented substantially perpendicular to a second gas path defining said gas movement through said second chamber to said at least one exhaust port, wherein at least one of said baffle walls are coupled at one side to one side of said second chamber that is substantially parallel to said second gas path, said second plurality of baffle walls are formed with said material that flexibly displaces or moves on when said gas moves along said second gas path and past said second plurality of baffle walls.

3 . A gas operated projectile firing system suppressor as in claim 2 ,
wherein said first chamber has at least one wall that is substantially parallel to said first axis that comprises a first elastic membrane, wherein said first elastic membrane is adapted to maintain position until at least a first force is applied by said gas along said first gas path, wherein said first elastic membrane is adapted to move or deflect when said gas traveling in said first gas path applies at least said first force to said first elastic membrane and thereby enables said gas traveling in said first gas path to pass by one end of said first plurality of baffle walls in proximity to said first elastic membrane; wherein said second chamber has at least one wall that is substantially parallel to said first axis that comprises a second elastic membrane, wherein said second elastic membrane is adapted to maintain position until at least a second force is applied by said gas along said second gas path, wherein said second elastic membrane is adapted to move or deflect when said gas traveling in said second gas path applies at least said second force to said second elastic membrane and thereby enables said gas traveling in said second gas path to pass by one end of said second plurality of baffle walls in proximity to said first elastic membrane.

4 . A gas operated projectile firing system suppressor as in claim 2 , comprising:
a first elastomer cover forming a wall of one side of said first chamber that is substantially parallel to said first axis, wherein said first elastomer cover is formed over said first plurality of baffle walls; and a second elastomer cover forming a wall of one side of said second chamber that is substantially parallel to said first axis, wherein said second elastomer cover formed over said second plurality of baffle walls.

5 . A gas operated projectile firing system suppressor as in claim 4 , wherein said first elastomer cover and said second elastomer cover comprise a silicone based elastomer.

6 . A gas operated projectile firing system suppressor as in claim 4 , wherein said first elastomer cover is varied in thickness along a length of said first chamber.

7 . A gas operated projectile firing system suppressor as in claim 4 , wherein said second elastomer cover is varied in thickness along a length of said second chamber.

8 . A gas operated projectile firing system suppressor as in claim 2 , comprising an elastomer cover over said first chamber and said second chamber of said suppressor structure, wherein said elastomer cover is stretched over said first plurality of baffle walls and said second plurality of baffle walls.

9 . A gas operated projectile firing system suppressor as in claim 8 , wherein said elastomer cover comprises a silicone based elastomer.

10 . A gas operated projectile firing system suppressor as in claim 8 , wherein said elastomer cover is varied in thickness along a length of said suppressor structure.

11 . A gas operated projectile firing system suppressor as in claim 1 , wherein said first chamber is adapted to rotate around said barrel and thereby selectively close off conveyance of said gas from said barrel port to said first chamber via said gas intake port.

12 . A gas operated projectile firing system suppressor as in claim 1 , wherein said exhaust port is formed into a circumferential side of said suppressor structure that is substantially perpendicular to said first axis.

13 . A gas operated projectile firing system suppressor as in claim 1 , wherein said exhaust port is adapted to expel gas from said second chamber in a direction substantially parallel with said barrel.

14 . A gas operated projectile firing system suppressor as in claim 1 , comprising an accessory mount, wherein said accessory mount is disposed and fixed over said suppressor structure.

15 . A gas operated projectile firing system suppressor as in claim 14
