Firearm sound and flash suppressor having low pressure discharge

摘要

A firearm noise suppressor and flash hider device having a tubular housing having left hand threaded components. A suppressor mount securing and aligning the tubular housing relative to a firearm barrel. A number of propellant gas handling members within the housing define aligned projectile ports and baffle chambers to permit projectile movement and slow the progress of propellant gas as it traverses the internal chamber. These gas handling members define primary and secondary flow paths within the housing to divide the propellant gas discharge from the barrel and minimize gas pressure and volume of flow, resulting in lower propellant pressure, minimized noise and propellant flash. The primary and secondary flow paths each have separate discharge openings at the forward end of the suppressor.

1. A noise suppressor and flash hider device for mounting to the externally threaded end of a firearm barrel, comprising:
a tubular housing defining an internal housing chamber; a suppressor mount being connected with the externally threaded section at the muzzle end of a firearm barrel and providing for support and alignment of said tubular housing; a plurality of propellant gas handling members being located within said elongate tubular housing and defining a primary flow path for propellant gas having a plurality of serially arranged internal propellant gas chambers, said plurality of propellant gas handling members defining spaced projectile ports through which projectiles and propellant gas pass, said tubular housing and said plurality of propellant gas handling members defining primary and secondary propellant gas flow paths within said tubular housing; said tubular housing having a front wall structure defining a projectile and propellant gas exit port in communication with said primary propellant gas flow path and defining a propellant gas exhaust port in communication with said secondary propellant gas flow path; said front wall defining a front wall surface and having a plurality of propellant gas exhaust passages each in communication with said secondary propellant flow path and having passage exhaust openings at said front wall surface; and said plurality of propellant gas exhaust passages being of angulated orientation and having exhaust ports arranged in a substantially circular array and directing propellant gas exhaust from said secondary flow path to converge with propellant gas being discharged from said projectile and propellant gas exit port.
