A firing report suppressor of small-arms has a unit for joining to arm barrel, hollow body connected to it with one end, placed in the body, coaxially with respect to axis of barrel of arm movable and fixed perforated tube, cross rings-partitions that form chambers, and devices for sealing inner cavity of suppressor connected to those, and springy device for turn and fixation of movable elements. The sealing devices are arranged as one or several installed coaxially at outlet from central tube or its parts valves with gaskets at conical surfaces reamed in direction of travel of bullet, in cross fixed elements of the body. Shutoff section of the valve is made of elastic three-dimension segment-sector elements hermetic in closed state and open in free state by value not less than inner diameter of central tube. |
