US12487046 - Suppressor

A suppressor comprising a cylindrical housing ( 1 ) and a core ( 2 ) with radially located disk partitions ( 3 ) arranged along it, wherein the thickness of the disk partitions ( 3 ) decreases in the direction from the rear to the front of the suppressor, a number of gas openings ( 4 ) are provided along the core, a sound-absorbing material is placed in working chambers between two adjacent disk partitions ( 3 ), and clamping grooves ( 6 )—offset from each other—are provided in the core ( 2 ) yielding a torque to the core when gas escapes therethrough, the sound-absorbing material being a cooling mesh ( 7 ) formed in a structured package ( 8 ) with an annular shape, consisting of two folded accordion-like strips, one of said strips being folded radially and the other being folded axially in relation to the axis of the compressor.

The patent describes a suppressor featuring a cylindrical housing and a core with disk partitions that decrease in thickness from rear to front, designed to create interconnected working chambers with gas openings. It incorporates a sound-absorbing cooling mesh structured in an annular shape, with specific ratios for volume and area to enhance sound suppression efficiency.

Claim 1

1 . A suppressor comprising: a cylindrical housing; a core of radially located disk partitions arranged along said cylindrical housing; the thickness of these decreases in the direction from the rear to the front of the suppressor; a number of gas openings are made along the core, one row is offset from the openings of another row the partitions and the gas openings form interconnected working chambers; a sound-absorbing material is placed in the working chambers between two adjacent disk partitions; at least two, clamping grooves—offset from each other—are placed in the core; wherein the sound-absorbing material in the space between the disk partitions is a cooling mesh, with the size of the openings from 0.02-2.00 mm and wherein said cooling mesh is formed in a structured package with an annular shape, a ratio of working chamber mesh volume mm 3 to mesh cooling area mm 2 , defined by the surface area of the mesh material, is 1:1 to 1:1.4. a cylindrical housing; a core of radially located disk partitions arranged along said cylindrical housing; the thickness of these decreases in the direction from the rear to the front of the suppressor; a number of gas openings are made along the core, one row is offset from the openings of another row the partitions and the gas openings form interconnected working chambers; a sound-absorbing material is placed in the working chambers between two adjacent disk partitions; at least two, clamping grooves—offset from each other—are placed in the core; wherein the sound-absorbing material in the space between the disk partitions is a cooling mesh, with the size of the openings from 0.02-2.00 mm and wherein said cooling mesh is formed in a structured package with an annular shape, a ratio of working chamber mesh volume mm 3 to mesh cooling area mm 2 , defined by the surface area of the mesh material, is 1:1 to 1:1.4.
