Abstract:
An acoustical wave suppressor for a tube barrel weapon comprising:a. a substantially tubular main body having a length and having a diameter greater than the outer diameter of the tube barrel weapon, and in a coaxial relationship relative to the axis of the tube barrel weapon; b. a first closed end closing said tubular main body at a first end, said first closed end being solidly mounted to a muzzle of the tube barrel weapon, and having an opening to said muzzle; c. a second closed end closing said tubular main body at a second end, said second closed end having a hole therethrough aligned to the axis of the tube barrel weapon; d. a cylindrical blast divider tube mounted through said hole in said second closed end, said cylindrical blast divider tube having a bore greater than the bore of said tube barrel weapon, a length of about 40% to about 85% of the axial length of said tubular main body, and being aligned with the axis of said tube barrel weapon, e. wherein said cylindrical blast divider tube creates a blind space formed along the length of said cylindrical blast divider tube between said cylindrical blast divider tube and said tubular main body and an expansion space formed between an end of said cylindrical blast divider tube and said muzzle of said tube barrel weapon, and wherein said blind space has an inlet opening occupying the full available cross-sectional area between said cylindrical blast divider tube and said tubular main body, thereby allowing unrestricted passage of expansion gases from said expansion space to said blind space.
