Firearm discharge gas flow control
A firearm discharge gas flow control device can comprise a first gas chamber fluidly connectable to a muzzle end of a firearm to allow a projectile to pass through and to receive a first portion of a discharge gas generated by firing the projectile. The device can also comprise a second gas chamber fluidly isolated from the first gas chamber and fluidly connectable to the muzzle end of the firearm to receive a second portion of the discharge gas, the second gas chamber having a flow control barrier to modify a flow of the second portion of the discharge gas.
1. A firearm discharge gas flow control device, comprising:
a first gas chamber fluidly connectable to a muzzle end of a firearm to allow a projectile to pass therethrough and to receive a first portion of a discharge gas generated by firing the projectile; and
a second gas chamber fluidly isolated from the first gas chamber and fluidly connectable to the muzzle end of the firearm to receive a second portion of the discharge gas, the second gas chamber having a flow control barrier to modify a flow of the second portion of the discharge gas.
2. The device of claim 1 , wherein the barrier is adjustable and comprises apertures of different sizes to allow varying flow rates of the second portion of the discharge gas.
3. The device of claim 2 , wherein the barrier is a plate rotatable about an axis that is parallel to a direction of travel of the projectile.
4. The device of claim 2 , wherein the barrier is adjustable to completely block the flow of the second portion of the discharge gas.
5. The device of claim 2 , wherein the barrier is adjustable to allow unimpeded flow of the second portion of the discharge gas.
6. The device of claim 1 , wherein the barrier is a fixed plate that completely blocks the flow of the second portion of the discharge gas.
7. The device of claim 1 , wherein the barrier is a spring-loaded plate that resists the flow of the second portion of the discharge gas up to a predetermined pressure.
8. The device of claim 1 , wherein the barrier is a movable back pressure plate having a spring that biases the back pressure plate in a closed position such that the flow of the second portion of the discharge gas is allowed past the plate while back flow is substantially prevented.
9. A firearm system, comprising:
a firearm; and
a firearm discharge gas flow control device having
a first gas chamber fluidly connected to a muzzle end of the firearm to allow a projectile to pass therethrough and to receive a first portion of a discharge gas generated by firing the projectile; and
a second gas chamber fluidly isolated from the first gas chamber and fluidly connected to the muzzle end of the firearm to receive a second portion of the discharge gas, the second gas chamber having a flow control barrier to modify a flow of the second portion of the discharge gas.
10. The system of claim 9 , wherein the barrier is adjustable and comprises apertures of different sizes to allow varying flow rates of the second portion of the discharge gas.
11. The system of claim 10 , wherein the barrier is a plate rotatable about an axis that is parallel to a direction of travel of the projectile.
12. The system of claim 10 , wherein the barrier is adjustable to completely block the flow of the second portion of the discharge gas.
13. The system of claim 10 , wherein the barrier is adjustable to allow unimpeded flow of the second portion of the discharge gas.
14. The system of claim 9 , wherein the barrier is a fixed plate that completely blocks the flow of the second portion of the discharge gas.
15. The system of claim 9 , wherein the barrier is a spring-loaded plate that resists the flow of the second portion of the discharge gas up to a predetermined pressure.
16. The system of claim 9 , wherein the barrier is a movable back pressure plate having a spring that biases the back pressure plate in a closed position such that the flow of the second portion of the discharge gas is allowed past the plate while back flow is substantially prevented.
17. The system of claim 9 , further comprising a suppressor fluidly connected to the muzzle end of the firearm and to the firearm discharge gas flow control device.
18. A method of controlling gas flow discharged from a firearm, comprising:
disposing a firearm discharge gas flow control device proximate to a muzzle end of a firearm; and
firing a projectile from the firearm, wherein a first gas chamber of the device is fluidly connected to the muzzle end of the firearm to allow the projectile to pass therethrough and to receive a first portion of a discharge gas generated by firing the projectile, and a second gas chamber of the device is fluidly isolated from the first gas chamber and fluidly connected to the muzzle end of the firearm to receive a second portion of the discharge gas, the second gas chamber having a flow control barrier to modify a flow of the second portion of the discharge gas.
19. The method of claim 18 , further comprising adjusting the barrier to vary a flow rate of the second portion of the discharge gas, the barrier having apertures of different sizes to allow various flow rates.
20. The method of claim 19 , wherein the barrier is a plate and adjusting the barrier comprises rotating the plate about an axis that is parallel to a direction of travel of the projectile.
21. The method of claim 18 , wherein disposing a firearm discharge gas flow control device proximate to a muzzle end of a firearm comprises disposing the device adjacent to a suppressor.
