US12326310 - Firearm noise suppressor

A suppressor system for a firearm having aligned sleeve openings between the barrel or a central tube and an inner sleeve. The suppressor system further includes dividers located between an outer sleeve and the inner sleeve. The suppressor system provides improved noise attenuation through the expansion of hot gasses multiple cavities in the suppressor system and also by slowing the hot gasses via tortuous pathways or collision of hot gasses in the suppressor system.

firearmsuppressornoiseattenuation

The patent describes a firearm suppressor system designed to enhance noise reduction by utilizing aligned sleeve openings and dividers that create multiple cavities for gas expansion and slow gas movement through complex pathways. This configuration aims to improve sound attenuation from the discharge of a bullet by effectively managing the hot gases produced during firing.

Claim 1

A suppressor system for attenuating sound of hot gases from a bullet in a firearm, the suppressor system comprising: an inner sleeve surrounding a barrel of the firearm; an outer sleeve surrounding the barrel and the inner sleeve; a plurality of barrel openings circumferentially disposed adjacent a muzzle end of the barrel; wherein the inner and outer sleeve surrounds the plurality of barrel openings; and a plurality of inner sleeve openings circumferentially disposed around the inner sleeve, wherein each inner sleeve opening of the plurality of inner sleeve openings are aligned with each barrel opening of the plurality of barrel openings; and wherein, within a plane perpendicular to a longitudinal axis of the barrel of the firearm, each barrel opening is spaced 90° from adjacent most barrel openings within the plane, and each inner sleeve opening is spaced 90° from adjacent most sleeve openings within the plane. an inner sleeve surrounding a barrel of the firearm; an outer sleeve surrounding the barrel and the inner sleeve; a plurality of barrel openings circumferentially disposed adjacent a muzzle end of the barrel; wherein the inner and outer sleeve surrounds the plurality of barrel openings; and a plurality of inner sleeve openings circumferentially disposed around the inner sleeve, wherein each inner sleeve opening of the plurality of inner sleeve openings are aligned with each barrel opening of the plurality of barrel openings; and wherein, within a plane perpendicular to a longitudinal axis of the barrel of the firearm, each barrel opening is spaced 90° from adjacent most barrel openings within the plane, and each inner sleeve opening is spaced 90° from adjacent most sleeve openings within the plane.
