PCT No. PCT/FI82/00052 Sec. 371 Date Jun. 17, 1983 Sec. 102(e) Date Jun. 17, 1983 PCT Filed Nov. 2, 1982 PCT Pub. No. WO83/01680 PCT Pub. Date May 11, 1983.A silencer for the barrel of a firearm comprises a sheath defining an interior space having open opposite ends. The sheath has a longitudinal axis. A plurality of partitioned plates are connected to the sheath and extend across the interior space thereof. Each partition plate has an opening therethrough of a size which is wider than a caliber of the firearm barrel and which lies in a plane which is inclined at an acute angle with respect to the axis. Each partition plate, in a direction along the axis, is rotated around the axis by a selected angle with respect to a previous partition plate to produce a convoluted path for gases discharged from the gun barrel. The first partition plate in the sheath adjacent a firearm valve which is connected to one open end of the sheath, defines an initial expansion chamber for the gases. |
