Sound suppressor system

Abstract

Sound suppression devices may include a baffle system or stack having a plurality of baffle disks where at least a first portion of the disks include a first set of gas ports and at least a second portion of the disks include a second set of gas ports. The baffle system may be configured to act as a compressing piston. When a bullet leaves a muzzle of a firearm and enters a suppression device, the baffle system acts as a compressing piston and moves forward with the gas pressure caused by the firing of the bullet. As the bullet begins to enter each baffle disk, the pressure starts to subside until there is a point where there is equalization between gas pressure and, for example, tension on a piston spring within the baffle system. After this point, the piston is driven back into place by the releasing of the spring tension.

         4 . The sound suppression device of  claim 3  further comprising a second spring configured to be disposed between the plurality of disks in the baffle stack and the muzzle end of the suppressor housing. 
     
     
         5 . The sound suppression device of  claim 1  wherein the end cap is configured to be a flash suppressor. 
     
     
         6 . The sound suppression device of  claim 5  wherein the end cap comprises a plurality of vents and a cross-shaped opening. 
     
     
         7 . The sound suppression device of  claim 1  further comprising a third type of disk having a third number of vent apertures configured to be placed within the baffle stack. 
     
     
         8 . The sound suppression device of  claim 1  wherein the baffle stack is configured to be aligned such that one or more vent apertures on the plurality of disks maintains alignment. 
     
     
         9 . A sound suppression device comprising:
 a suppressor housing;   an attachment portion configured to attach the suppressor housing to the muzzle end of a firearm;   a baffle stack configured to be inserted within the suppressor housing, the baffle stack having a plurality of disks having one or more vent apertures; and   at least one spring configured to be retained within the suppressor housing between a housing edge and the baffle stack;   an end cap configured to attach to the suppressor housing and secure the baffle stack within the housing.   
     
     
         10 . The sound suppression device of  claim 9  wherein the baffle stack is configured to move laterally along a longitudinal axis defined by the length of the suppressor housing against the spring. 
     
     
         11 . The sound suppression device of  claim 10  wherein the at least one spring comprises a first spring configured to be disposed between the plurality of disks in the baffle stack and the end cap and a second spring configured to be disposed between the plurality of disks in the baffle stack and the muzzle end of the suppressor housing. 
     
     
         12 . The sound suppression device of  claim 10  wherein the plurality of disks includes: one or more disks having a first number of vent apertures and one or more disks having a second number of vent apertures. 
     
     
         13 . The sound suppression device of  claim 9  wherein the end cap is configured to be a flash suppressor. 
     
     
         14 . The sound suppression device of  claim 13  wherein the end cap comprises a plurality of vents and a cross-shaped opening. 
     
     
         16 . The sound suppression device of  claim 9  wherein the baffle stack is configured to be aligned such that one or more vent apertures on the plurality of disks maintains alignment. 
     
     
         17 . The sound suppression device of  claim 16  wherein the baffle stack is configured to maintain alignment using a notch portion in one or more disks of the plurality of disks. 
     
     
         18 . The sound suppression device of  claim 16  wherein the baffle stack is configured to maintain alignment using complimentary nesting portions between one or more disks of the plurality of disks. 
     
     
         19 . A method for manufacturing a sound suppression device comprising:
 forming a suppressor housing having an attachment portion configured to attach the suppressor housing to the muzzle end of a firearm;   providing a baffle stack configured to be inserted within the suppressor housing, the baffle stack having a plurality of disks of a first type and a plurality of disks of a second type, wherein the plurality of disks of a first type each define a first number of vent apertures and the plurality of disks of a second type each define a second number of vent apertures; and   providing an end cap configured to attach to the suppressor housing and secure the baffle stack within the housing.   
     
     
         20 . The method of  claim 19  further comprising: providing one or more springs configured to be inserted into the suppressor housing and to be disposed between the baffle stack and one or more of the muzzle end of the housing and the end cap.
