Abstract:
A silencer for a firearm comprising two or more separate chambers (1, 2, 3, 4, 5) formed longitudinally in the silencer, the chambers (1, 2, 3, 4, 5) being defined by an outer sleeve (12) and an inner sleeve (13) which extend longitudinally in the silencer, and a number of disc-shaped surfaces (8, 9, 10, 11) which extend between the outer and inner sleeves (12, 13), a number of holes (6) formed in a boundary surface between at least one of the chambers (1, 3, 4) and a central bore (16) through the silencer, thereby allowing, after a shot, the gas emitted from the muzzle (19) of the firearm to flow into the at least one chamber (1, 3, 4), the holes (6) extending radially through the boundary surface towards the central bore (16) and the holes (6) of one row being offset relative to the holes (6) of an adjacent row, and a threaded connection (15) formed on the inside of the inner sleeve (13) for fitting the silencer to the firearm (20), at least one of the chambers (1), when the silencer is fitted to the firearm, being positioned in front of the muzzle and at least another of the chambers (2, 5) being positioned behind the muzzle (19), the at least another chamber (2, 5) behind the muzzle (19) being provided with openings (7) formed in a surface (8) between the chamber (1) in front of the muzzle and the chamber (2) behind the muzzle (19), thereby allowing the emitted gas received by the chamber (1) in front of the muzzle (19) to flow rearwards into the chamber (2) behind the muzzle.
