Zusammenfassung: | The invention is intended for suppression of shot report at carrying out military and special operations, and training, study, hunting and other types of shooting. The silencer has a front flange with device for fixation barrel of the arm, cylindrical hollow body and end flange connected to each other. In the cavity of the body a perforated with side openings central tube is placed, and three cross partitions are installed, those form four expansion chambers. In the cross partitions perforation openings are provided, the long axles of those are parallel to the long axis of the silencer. In the first expansion chamber the central tube is arranged and a diffuser installed with an end gap with respect to the inner plane of the front flange, or as a section of the tube that connects without a gap the first partition and the inner plane of the front flange. In the second, third and fourth expansion chambers groups of sections of cylindrical shells with axial symmetry are placed, the long axles of those are parallel to the long axis of the silencer, the side surfaces are perforated with slot openings, those are adjacent simultaneously to the outer surface of the central tube, the inner surface of the body of the silencer and to each other. The slot perforation openings of the central tube are installed in front of the slot perforation opening of one of the sections in the group, and in the places of touch of those slot perforation openings are provided as well. Each next group of sections of the shells is turned with respect to the previous one by angle equal to half of the angle of installation of sections of the shells in expansion chamber. The invention provides decrease of the shot report level on retention of mass and dimensions parameters, technological, cost and operation characteristics.
