Abstract: The present invention is for a firearm sound suppressor which is attached to the barrel of a firearm to reduce the noise and flash generated by the firearm. The firearm sound suppressor improves the dissipation of heat and provides a breach head on the end thereof for use as a ramming and breaching instrument.

Abstract: A sound suppressor for firearms (such as hand guns and rifles) has a tubular body with a first end cap adjacent the barrel of the firearm, and a 5 second end cap with exhaust vents for the gases. A plurality of baffles, each having a passage for the bullet, are provided in the body intermediate the first-and-second end caps. Each baffle has a plurality of vents in the outer portion, the vents forming at least one path for the flow of the major portion of the gases through the suppressor body. By angularly offsetting the vents of adjacent baffles, the gas path(s) are made tortuous to further slow the gas flow. The baffle adjacent the first end cap can be a deflecting baffle, where the vents deflect the gases outwardly towards the body. The body may be connected to the barrel of the firearm by screw-threads or a bayonet coupling; and a flash eliminator may be connected to the body adjacent the second end cap.

The interior member is disposed within the housing so as to define a chamber between an exterior surface of the interior member and an interior surface of the housing. The interior member includes a lumen and a plurality of vents extending through the interior member between the lumen and the chamber. The vents are adapted to pass combustion gases from the lumen to the chamber. The firearm sound suppressor also includes a blast deflector disposed between the vents and the interior surface of the housing. The blast deflector is adapted to prevent the combustion gases from impinging directly on the interior surface of the housing. Other embodiments are also contemplated.

Other embodiments are also contemplated.

Abstract: A Controlled Unaided Surge and Purge Suppressor for firearms uses the blast and plume characteristics inherent to the ballistic discharge process to develop a new two-step controlled surge and purge system centered around advanced mixer-ejector concepts. The blast surge noise is reduced by controlling the flow expansion, and the flash effects are reduced by controlling inflow and outflow gas purges. This is a C-I-P application. In the preferred C-I-P embodiment, the blast surge is mitigated via a slotted mixer nozzle; a first expansion chamber; a generally “wagon-wheel” shaped blast baffle with a vent hole; a series of alternating baffles, with vent holes, strategically located along the suppressor's inner wall surface; a second expansion chamber; and an exit opening. This preferred C-I-P embodiment contains no “outside” vent holes (i.e., throughbores) which extend through the suppressor's outer or longitudinal wall.

Just past the muzzle-seat in the central bore is a flared entrance leading to the gaps thereby allowing hot air and combustion gases to expand radially through the gaps between the tines, thereby cooling the hot air and gases. The lateral faces of the tines are stepped to cause turbulent mixing of the cooler air surrounding the flash hider with the exiting gases so as to further expand and cool in order to prevent re-ignition and thereby reduce secondary flash. Long tines help to hide all but direct viewing of primary flash.

Abstract: A gun suppressor having a single or multiple vacuum chambers that create a vacuum enclosed volume for gases to expand into. Accordingly, the pressure of the gas that exits the suppressor is reduced significantly; therefore, the sound of the gun firing is more silent than conventional silencers. Prior to firing the gun, a vacuum seal is placed at the exit orifice of the suppressor and a vacuum is created inside of the suppressor with the use of a vacuum pump. The vacuum chamber reduces the pressure wave caused at the end of the firearm's barrel. When the firearm is discharged, the gases fill the vacuum chamber instead of exiting at normal atmospheric pressure level. As the bullet continues its travel through the end of the suppressor, it perforates the vacuum seal and continues its flight path.
