Abstract
A firearm discharge gas flow control module is fluidly coupleable to a muzzle end of a firearm to allow a projectile to pass therethrough. The gas flow control module includes an inlet port, operable to receive at least a portion of a discharge gas generated by firing the projectile, and a gas chamber, bounded by at least one wall that at least partially defines a geometry of the gas chamber. The gas chamber extends both radially and longitudinally from the inlet port and translates circumferentially as the gas chamber extends longitudinally. The gas chamber terminates at a circumferential angle of rotation from the inlet port, the circumferential angle of rotation being less than 180 degrees.
Claims22
A firearm discharge gas flow control module fluidly coupleable to a muzzle end of a firearm to allow a projectile to pass therethrough, the gas flow control module comprising:
- an inlet port adjacent a projectile bore defined through a longitudinal center of the module, the inlet port being operable to receive at least a portion of a discharge gas generated by firing the projectile;
- and
- a first gas chamber, bounded by the inlet port and at least one wall that at least partially defines a geometry of the gas chamber;
- the at least one wall of the first gas chamber extending both radially and longitudinally from the inlet port and translating circumferentially as the at least one wall extends longitudinally, such that discharge gas is forced to expand circumferentially as the discharge gas expands longitudinally;
- wherein
- the first gas chamber terminates at a circumferential angle of rotation from the inlet port, said circumferential angle of rotation being less than 180 degrees.
A firearms suppressor operable to be fluidly coupled to a muzzle end of a firearm, the suppressor comprising:
- a plurality of discharge gas flow control modules arranged in a longitudinal stack, each of the modules including a plurality of gas chambers arranged in a circumferentially offset orientation, each gas chamber being operable to receive a different portion of a discharge gas generated by firing a projectile;
- wherein
- each of the gas chambers is bounded by at least one wall that at least partially defines a geometry of the gas chamber, the at least one wall extending both radially and longitudinally from an inlet port adjacent a bore defined through a longitudinal center of each module and translating circumferentially as the at least one wall extends longitudinally, such that discharge gas is forced to expand circumferentially as the discharge gas expands longitudinally.
A method of controlling gas flow discharged from a firearm, comprising:
- arranging one or more gas flow control modules on the end of a muzzle of a firearm, each of the one or more modules including at least two gas chambers arranged in a circumferentially offset orientation, wherein each of the gas chambers is bounded by at least one wall that at least partially defines a geometry of the gas chamber, the at least one wall extending both radially and longitudinally from an inlet port adjacent a bore defined through a longitudinal center of each module and translating circumferentially as the at least one wall extends longitudinally, such that discharge gas is forced to expand circumferentially as the discharge gas expands longitudinally;
- discharging the firearm to fire a projectile, thereby generating discharge gas, a portion of the discharge gas which is thereby routed through the gas chambers of the modules.
