Definitions

  • This disclosure relates to suppressor baffles.
  • Suppressors for firearms are designed to dissipate the energy of gases and particulates discharged from the muzzle to reduce the ambient noise created by the discharge.
  • Typical suppressors have a plurality of baffles carried within a tube or other housing, and the baffles may be of various designs.
  • Each baffle has a bore for allowing a projectile to pass through the baffle, and the baffles are arranged in a stack for aligning the bores.
  • Figure l is a side view of a baffle section according to this disclosure.
  • Figure 2 is a rear oblique view of the baffle section of Figure 1.
  • FIG. 3 is a rear view of the baffle section of Figure 1.
  • This disclosure divulges a suppressor baffle section with a cone having a web of strengthening ribs.
  • the baffle section may be formed by additive manufacturing (3-D printing) or traditional machining methods and may be a separate component combined into a baffle stack or may be a portion of a unitary printed suppressor.
  • FIGS 1 through 3 illustrate baffle section 101, comprising outer wall 103, inner wall 105, and cone 107.
  • Outer wall 103 cooperates with an outer wall of adjacent sections to form an outer tube for containing gases and particulates (“gases”) expelled from a firearm barrel into the suppressor.
  • Outer wall 103 may be formed as an integral part of baffle section 101, as described above, and welded to adjacent outer walls, or outer wall 103 may be a portion of a tube into which is inserted the remainder of baffle section 101 together with additional suppressor components.
  • Inner wall 105 is spaced from outer wall 103 and forms a coaxial volume 109 therebetween, allowing for a portion of the gases to be directed into volume 109 through ports formed in inner wall 105.
  • Cone 107 forms a generally conical rear portion of baffle section 101 and has an aperture 111 with a notch 113. Aperture 111 cooperates with aligned apertures of additional suppressor components to form a bore through which a projectile may pass. Cone 107 acts to separate chamber volumes within suppressor behind and in front of cone 107. Cone 107 also acts to divert a portion of gases forward and radially outward from aperture 111, and some of the gases may be directed into one or more portions of coaxial volume 109.
  • Cone 107 comprises a solid wall 115 and a web 117 of strengthening ribs formed, in the embodiment shown, on an outer surface of wall 115.
  • Web 117 comprises a plurality of longitudinal ribs 119 and cross ribs 121, 123, 125, 127, which are fully or partially circumferential.
  • Cross rib 121 is located at the rear end of cone 107 around aperture 111, and longitudinal ribs 119 extend forward from rib 121.
  • Longitudinal ribs 119 are spaced from each other on wall 115 about cone 107 and may be equally spaced or have varying distances between ribs 119.
  • cross ribs 121, 123, 125, 127 are spaced from each other on wall 115 and may be equally spaced or have varying distances between ribs 121, 123, 125, 127.
  • Longitudinal ribs 119 extend along wall 115 generally from cross rib 121 forward to beyond cross rib 127. Longitudinal ribs 119 intersect cross ribs 121, 123, 125, 127, forming web 117. Each rib 119, 121, 123, 125, 127 has a selected height from wall 115, and the heights may be equal or vary, as may be required to achieve the desired strength of cone 107 with the minimum amount of material used. Voids 129 are formed by the intersections of ribs 119, 121, 123, 125, 127, the depth of each void 129 being determined by the height of ribs 119, 121, 123, 125, 127.
  • Web 117 strengthens cone 107 and serves to cause additional turbulence for gases flowing over cone 107. It should be noted that web 107 may alternatively be formed on an inside surface of wall 115 to, for example, allow for additional clearance around the outer surface of cone 107. Another alternative embodiment comprises web 107 on both the outer and inner surfaces of wall 115. [0014] At least one embodiment is disclosed, and variations, combinations, and/or modifications of the embodiment(s) and/or features of the embodiment s) made by a person having ordinary skill in the art are within the scope of the disclosure. Alternative embodiments that result from combining, integrating, and/or omitting features of the embodiment(s) are also within the scope of the disclosure.

Abstract

Un déflecteur de suppresseur selon l'invention présente un cône comprenant une paroi solide et formant une partie arrière généralement conique d'un déflecteur, le cône ayant une ouverture conçue pour coopérer avec des ouvertures alignées de composants de suppresseur supplémentaires pour former un alésage à travers lequel peut passer un projectile. Le cône est également conçu pour séparer des volumes de chambre à l'intérieur d'un suppresseur vers l'arrière et vers l'avant du cône. Une bande de nervures de renforcement est formée sur une surface externe orientée vers l'arrière ou sur une surface interne orientée vers l'avant de la paroi, la bande comprenant une pluralité de nervures longitudinales et de nervures transversales, les nervures étant espacées les unes des autres.
