SYSTEM AND METHOD FOR MULTI-STAGE BYPASS, LOW OPERATING TEMPERATURE SUPPRESSOR FOR AUTOMATIC WEAPONS

摘要

The present disclosure relates to a suppressor for use with a weapon. The suppressor may be formed to have a body portion having a bore extending concentric with a bore axis of the weapon barrel. An opening in the bore extends at least substantially circumferentially around the bore. A flow path communicates with the opening and defines a channel for redirecting gasses flowing in the bore out from the bore, through the opening, into a rearward direction in the flow path. The flow path raises a pressure at the opening to generate a Mach disk within the bore at a location approximately coincident with the opening. The Mach disk forms as a virtual baffle to divert at least a portion of the gasses into the opening and into the flow path.

主权项

1. A suppressor for use with a weapon that fires a bullet, the suppressor adapted to be secured to a distal end of a barrel of the weapon, the suppressor including:
a body portion having a bore extending concentric with a bore axis of the barrel when the suppressor is attached to the distal end of the barrel; an opening in the bore of the body portion extending at least substantially circumferentially around the bore; a flow path in communication with the opening and defining a channel for redirecting expanding propellant gasses flowing in a forward direction in the bore out from the bore, through the opening, initially into a rearward direction in the flow path, and subsequently back into the bore, and wherein the flow path helps to raise a pressure at the opening to a level which is sufficient to generate a Mach disk within the bore at a location approximately coincident with the opening, when a bullet from a cartridge is fired into the barrel, the Mach disk acting as a virtual baffle to divert at least a portion of the expanding propellant gasses behind the bullet into the opening and into the rearward direction defined by the flow path; and a discharge port in communication with the bore, the discharge port being formed at a downstream end of the suppressor where the bullet and the expanding propellant gasses exit the barrel.
