When sound and muzzle flash are not an option. This invention helps to keep our soldiers at war safer.

With the Vacuum/Suppressor in place, the pressurized gas behind the bullet has a vacuum chamber space to expand into, so the pressure of the gas that exits the tip of the suppressor is reduced significantly; therefore, the sound of the gun firing is more silent than conventional silencers.

The present invention is a firearm suppressor that uses a vacuum chamber to reduce the sound and flash levels that are typically created when a firearm is discharged.

The vacuum chamber(s) of the present invention adds a novel feature to firearm suppressors that enables the propellant gases to fill the vacuum chamber(s) and by this way to remain inside the suppressor for a longer period of time. The principal object of the present invention is that the vacuum chamber diminishes the volume of gases that exit the muzzle of the firearm caused by discharging the firearm. Another objective of the present invention is to reduce flash at the muzzle. Another objective of the present invention is to reduce the pressure wave caused at the end of the firearm's barrel. The distal end of the suppressor has en end cap to seal the exit hole of the suppressor and allow vacuum to be formed. The ammunition when loaded into the chamber of the barrel forms a seal at this location to allow a vacuum chamber to be created inside the barrel all the way to the end of the suppressor.

When the firearm is discharged the bullet travels through the barrel followed by high pressure gases. Once the bullet reaches the interior chamber of the suppressor, the gases will start to fill the vacuum chamber instead of finding a volume of air at normal atmospheric pressure level. As the bullet continues its travel through the distal end of the suppressor, it will perforate the vacuum seal and continue its flight path.

After a single shot, the vacuum seal is destroyed and a new seal must be positioned at the distal end of the suppressor. Once a new round of ammunition is loaded into the firing chamber of the firearm's barrel and a new seal is placed in the distal end of the suppressor, the vacuum generator or pump can be used to remove most of the air from inside the suppressor and barrel and prepare the firearm for the next use. If an immediate second shot is required, the suppressor will still work just as a standard silencer would.
