Suppressor for a firearm

Abstract

A device for use in a firearm suppressor or silencer wherein the device directs the high-pressure gas away from the center of the suppressor or silencer. A preferred embodiment of the device is a baffle with a hollow tubular body of cylindrical cross section casing narrowing to a cone shape having sides that define an inlet and outlet end with an interior and exterior surface. The casing has a plurality of apertures and an exterior flow passage or channel extending around the apertures on the exterior surface of the casing. The apertures and flow passages or channels are configured to turn the gas passing through the baffle from a first direction in which the gas exits towards the center of the baffle to a second direction in which the gas exits the baffle away from the center of the baffle.

What is claimed is: 
     
         1 . A suppressor for a firearm configured to turn gas passing through the suppressor from a first direction of a central trajectory through the suppressor to a second direction in which the gas is directed away from the center of the suppressor and through the length of the suppressor. 
     
     
         2 . A suppressor for a firearm comprising:
 a. a tubular housing of cylindrical cross section having an interior cavity;   b. a plurality of baffles with a hollow tubular body of cylindrical cross section having sides that define a gas inlet and a gas outlet end, an interior and exterior surface, and are nested within each other in the interior cavity; and   c. a plurality of apertures on the exterior surface of the baffles.   
     
     
         3 . The suppressor of  claim 2  wherein the apertures direct gas passing through the suppressor from a first direction through a center of the suppressor to a second direction in which the gas exits through the apertures and is directed away from the center of the suppressor and through a horizontal length of the tubular casing. 
     
     
         4 . The suppressor of  claim 2  further comprising at least one exterior flow passage or channel on the exterior surface of the baffle and extending upwards from the exterior surface of the baffle around the apertures. 
     
     
         5 . The suppressor of  claim 4  wherein the flow passages or channels of the baffle are configured to turn gas passing through the apertures away from the center of the suppressor and through a horizontal length of the tubular casing. 
     
     
         6 . The suppressor of  claim 2  wherein each of the plurality of baffles has a center point aligned with a longitudinal axis of the baffle and wherein the tubular housing has a center point aligned with a longitudinal axis of the tubular housing. 
     
     
         7 . The suppressor of  claim 6  wherein the center points of the baffles align with the center point of the tubular housing. 
     
     
         8 . The suppressor of  claim 2  wherein the each of the plurality of baffles narrow to a cone shape at the gas outlet end. 
     
     
         9 . The suppressor of  claim 2  further comprising
 a. an outer casing with a proximal and a distal end; 
 b. a plurality of apertures around a perimeter of the casing at the distal end; and 
 c. a threaded connection along an interior perimeter of the casing at the proximal end. 
 
     
     
         10 . The suppressor of  claim 2  further comprising at least one spacer between two of the baffles, the spacer comprising:
 a. a hollow tubular body of cylindrical cross section with an interior and exterior surface; and 
 b. at least one exterior flow passage or channel on the exterior surface of the baffle and extending upwards from the exterior surface of the baffle. 
 
     
     
         11 . The suppressor of  claim 10  wherein the flow passages or channels of the spacers are configured to turn gas passing through the apertures of the baffles away from the center of the suppressor. 
     
     
         12 . The suppressor of  claim 10  further comprising a plurality of apertures on the exterior surface of the spacer wherein the exterior flow passages or channels are around the aperture. 
     
     
         13 . The suppressor of  claim 12  wherein the flow passages or channels of the spacer are configured to turn gas passing through the suppressor from a first direction through a center of the suppressor to a second direction in which the gas exits through the apertures and is directed by the flow passages or channels away from the center of the suppressor and through a horizontal length of the tubular casing. 
     
     
         14 . A baffle for use in a firearm suppressor comprising:
 a. a hollow tubular body of cylindrical cross section having sides that define a gas inlet and gas outlet end with an interior and exterior surface; and   b. a plurality of apertures on the exterior surface of the baffle.   
     
     
         15 . The baffle of  claim 14  wherein the apertures direct gas passing through the baffle from a first direction through a center of the baffle to a second direction in which the gas exits through the apertures and is directed away from the center of the baffle. 
     
     
         16 . The baffle of  claim 14  further comprising at least one exterior flow passage or channel on the exterior surface of the baffle and extending upwards from the exterior surface of the baffle around the apertures. 
     
     
         17 . The baffle of  claim 14  wherein the flow passages or channels are configured to turn gas passing through the baffle from a first direction through a center of the baffle to a second direction in which the gas exits through the apertures and is directed by the flow passages or channels away from the center of the suppressor. 
     
     
         18 . A spacer for use in a firearm suppressor comprising:
 a. a hollow tubular body of cylindrical cross section having sides that define an inlet and outlet end with an interior and exterior surface; and   b. an exterior flow passage or channel extending around the apertures on the exterior surface of the spacer.   
     
     
         19 . The spacer of  claim 18  wherein the flow passages or channels are configured to turn gas passing around the outside of the spacer from a first direction through a center of the spacer to a second direction in which the gas exits through the apertures and is directed by the flow passages or channels away from the center of the spacer and through a horizontal length of the spacer. 
     
     
         20 . The spacer of  claim 18  further comprising a plurality of apertures on the exterior surface of the spacer. 
     
     
         21 . The spacer of  claim 20  wherein the flow passages or channels are configured to turn gas passing through the spacer from a first direction through a center of the spacer to a second direction in which the gas exits through the apertures and is directed by the flow passages or channels away from the center of the spacer and through a horizontal length of the spacer. 
     
     
         22 . A mount for use in a firearm suppressor comprising
 a. an outer casing with a proximal and a distal end;   b. a plurality of apertures around a perimeter of the casing at the distal end; and   c. a threaded connection along an interior perimeter of the casing at the proximal end.
