DUCTED FIREARM SUPPRESSOR
Abstract
A suppressor is provided to reduce the sound produced by a
firearm. The Suppressor comprises a body with a muzzle attachment
facility and the body defines a linear bullet passage with a bullet
exit aperture. Further, the body of the suppressor defines an
articulated gas path away from the bullet passage, and the gas path
has a plurality of overlaying forward flow segments and rearward
flow segments and an exit aperture away from the bullet exit
aperture.

Description
CROSS-REFERENCE TO RELATED APPLICATIONS
[0001] This application claims the benefit of U.S. Provisional
Patent Application No. 62/633,640 filed on Feb. 22, 2018, entitled
"Ducted Firearm Suppressor", which is hereby incorporated by
reference in its entirety for all that is taught and disclosed
therein.
FIELD OF THE INVENTION
[0002] The present invention relates to a ducted firearm
suppressor, and more particularly, to a suppressor that contains
blast diversion features and reduces the sound produced by a
firearm.
BACKGROUND OF THE INVENTION
[0003] Recent advancements in manufacturing technologies have
expanded the design space of engineers. The ducted firearm
suppressor described in this application relies on these new
manufacturing technologies to be produced.
[0004] The limitations of the prior art are addressed by providing
a suppressor to reduce the sound produced by a firearm. The
Suppressor comprises a body with a muzzle attachment facility and
the body defines a linear bullet passage with a bullet exit
aperture. Further, the body of the suppressor defines an
articulated gas path away from the bullet passage, and the gas path
has a plurality of overlaying forward flow segments and rearward
flow segments and an exit aperture away from the bullet exit
aperture.
SUMMARY OF THE INVENTION
[0005] The present invention is intended to reduce the sound
produced by a firearm as the blast exits the muzzle of the
barrel.
[0006] The present invention consists of a body that contains blast
diversion features and ducting that allow the blast pressure to
dissipate over a longer period of time, cool to some extent, and
exit through different openings than the projectile exit port.
[0007] The present invention and its manufacturing method allow for
more compact applications as it reduces the overall length
extension from the end of the barrel.
[0008] The present invention routes the blast gases via ducting
under or around the barrel and allows the gases to flow freely as
opposed to the traditional methods of containing the blast gases
with various baffle designs.
[0009] The body of the present invention also has features to allow
mounting to a firearm muzzle and can be configured to various
mounting methods.
BRIEF DESCRIPTION OF THE DRAWINGS
[0010] FIGS. 1-32 show van of a preferred embodiment of the
invention.
DETAILED DESCRIPTION OF A PREFERRED EMBODIMENT
