Abstract:
A compact silencer (suppressor) device for a firearm comprising of multiple chambers which trap the gases from a projectile exiting the barrel of a gun to slow down the gases and reduce the temperature, sound, and flash associated with the projectile. In one embodiment, the first chamber which attaches to the barrel of the firearm comprises of sound baffling materials or gas porting baffles which vent gases from the second chamber passing rearward. The second chamber comprises of a chamber which can accommodate a retractable third chamber of the device, the second and third chamber of the device can have sound baffles to slow down the gases from the projectile.

Claim (Index 1):
A silencer apparatus for suppressing the sound of a projectile fired from a firearm, the silencer apparatus comprising:\n at least a first chamber and a second chamber, each of said chambers having a cylindrical, oval, or rectangular shape; the first and second chambers being aligned longitudinally and sequentially along a bore line, wherein the bore line is coaxial with a longitudinal bore axis of a barrel of the firearm when the silencer apparatus is installed on the firearm; the first chamber comprising a first end cap on a proximal end thereof, the first end cap having an opening formed there-through, and the first end cap on a proximal side having a mechanical connection system, for attaching the silencer apparatus to a muzzle end of the barrel of the firearm such that the bore line and longitudinal bore axis are aligned;\n the first end cap being concentric with the bore line and including a concentric annular opening around the gun barrel and encompassing the gun barrel, wherein the first end cap is either solid or includes vent holes, \n the first end cap on the proximal end is attached to the proximal end of the first chamber; a guide ring formed on a distal end of the first end cap, the guide ring being concentric with the bore line and the concentric annular opening of the first end cap, and the guide ring being beveled along a distal side thereof and extending distally from the first end cap and functioning as an interface and alignment guide for a tube coming into contact with the guide ring along the bore line; the first chamber further including a radially inward projecting first flange on a distal end of the first chamber and a mechanical compression member, the mechanical compression member being connected with the first flange; the second chamber having a smaller diameter or cross-sectional area than the first chamber, the second chamber being wholly or partially inserted within the first chamber; the second chamber having a radially outwardly facing second flange on a proximal end thereof, the proximal end of the second chamber being disposed inside the first chamber; the mechanical compression member fitting between an outer surface of the second chamber and an inner surface of the first chamber; the mechanical compression member being disposed between the first flange and the second flange such that the mechanical compression member biases the second chamber into a retracted position in which the second chamber is retracted into the first chamber, and wherein the second chamber is movable relative to the first chamber longitudinally along the bore line from the retracted position to an expanded position, against the bias of the mechanical compression member, when the second chamber is acted upon by expanding gases within the silencer apparatus; the silencer apparatus further comprising a first inner tube disposed inside the second chamber and concentric with the bore line, the first inner tube being attached to a second end cap that is located at a distal end of the second chamber, the first inner tube having a diameter that is smaller than a diameter or cross-sectional area of the second chamber, and the diameter of the first inner tube being equal to or larger than the projectile; wherein a proximal end of the first inner tube contacts with the guide ring, such that the beveled portion of the guide ring causes the first inner tube to align concentrically with the bore line, when the second chamber is in the retracted position; wherein the silencer apparatus allows a projectile fired from the firearm to travel along the bore line through the first end cap, the first chamber, the first inner tube, the second chamber, and the second end cap, when the silencer apparatus is installed on the muzzle end of the barrel of the firearm; wherein all the elements concentric to the bore line and along the path of the projectile of the silencer allow for a free flow path of the projectile and are sized with one of a same diameter as the barrel or a diameter larger than the projectile.
