US12578160 - High-pressure air magazine

The patent describes a high-pressure air magazine designed to fit into a firearm’s magazine well, featuring a high-pressure chamber capable of withstanding 7000 psi and an air regulator that controls airflow to a low-pressure chamber. Additionally, it includes an air release valve that simulates firearm recoil and a counter to track the number of air bursts released.

Claim 1

1 . A high-pressure air magazine, comprising: an outer housing formed of a single piece of material that is sized and shaped to couple with a recoil kit for a firearm, the outer housing formed of aluminum and having a leading end configured to fit into a magazine well of a firearm, and a side surface extending from the leading end to a rear end of the outer housing, wherein the outer housing is configured to withstand a pressure of 7000 psi within the outer housing; a high-pressure chamber formed within the outer housing and sized to hold a predetermined quantity of pressurized air, the high-pressure chamber having a first end adjacent the leading end and formed with a rounded, semi-spherical surface, a second end adjacent the rear end of the high-pressure chamber having a chamber plug with a second rounded, semi-spherical surface therein such that when the chamber plug is coupled to the high-pressure air magazine, the high-pressure chamber is rounded at both the first end and the second end; a fill valve disposed between the high-pressure chamber and a fill port exposed on a side surface of the outer housing, the fill valve configured to couple with a high-pressure nozzle through the fill port to fill the high-pressure chamber with pressurized air, the fill port extending perpendicularly through the side surface and into a side of the high-pressure chamber between the first end and the second end; an air regulator fluidly coupled to the high-pressure chamber within the outer housing and configured to selectively pass air from the high-pressure chamber to a low-pressure chamber within the outer housing, the air regulator comprising: a regulator ball valve positioned between the high-pressure chamber and the low-pressure chamber, the regulator ball valve comprising a regulator ball biased by a compression spring to a closed position against an o-ring wherein airflow from the high-pressure chamber to the low-pressure chamber is minimized; a regulator valve screw exposed on the surface of the outer housing and configured to adjust a magnitude of the bias on the regulator ball created by the compression spring; a regulator piston exposed to the low-pressure chamber and in contact with the regulator ball valve, wherein when a pressure within the low-pressure chamber lowers past a predetermined pressure, the regulator piston is biased by a primary regulator spring to push the regulator ball valve from the closed position to an open position wherein air flows from the high-pressure chamber to the low-pressure chamber until the pressure within the low-pressure chamber reaches the predetermined pressure; and a regulator piston support nut exposed on the surface of the outer housing and configured to adjust the predetermined pressure by adjusting a magnitude of the bias on the regulator piston created by the primary regulator spring; an air release valve disposed between the low-pressure chamber and an air release port exposed on the surface of the outer housing, the air release valve configured to couple with the recoil kit and dispense a burst of air from the low-pressure chamber to the firearm through the recoil kit when the firearm is activated, wherein the burst of air causes the firearm to simulate a recoil of the firearm; and a counter configured to track a number of bursts of air released through the air release valve. an outer housing formed of a single piece of material that is sized and shaped to couple with a recoil kit for a firearm, the outer housing formed of aluminum and having a leading end configured to fit into a magazine well of a firearm, and a side surface extending from the leading end to a rear end of the outer housing, wherein the outer housing is configured to withstand a pressure of 7000 psi within the outer housing; a high-pressure chamber formed within the outer housing and sized to hold a predetermined quantity of pressurized air, the high-pressure chamber having a first end adjacent the leading end and formed with a rounded, semi-spherical surface, a second end adjacent the rear end of the high-pressure chamber having a chamber plug with a second rounded, semi-spherical surface therein such that when the chamber plug is coupled to the high-pressure air magazine, the high-pressure chamber is rounded at both the first end and the second end; a fill valve disposed between the high-pressure chamber and a fill port exposed on a side surface of the outer housing, the fill valve configured to couple with a high-pressure nozzle through the fill port to fill the high-pressure chamber with pressurized air, the fill port extending perpendicularly through the side surface and into a side of the high-pressure chamber between the first end and the second end; an air regulator fluidly coupled to the high-pressure chamber within the outer housing and configured to selectively pass air from the high-pressure chamber to a low-pressure chamber within the outer housing, the air regulator comprising: a regulator ball valve positioned between the high-pressure chamber and the low-pressure chamber, the regulator ball valve comprising a regulator ball biased by a compression spring to a closed position against an o-ring wherein airflow from the high-pressure chamber to the low-pressure chamber is minimized; a regulator valve screw exposed on the surface of the outer housing and configured to adjust a magnitude of the bias on the regulator ball created by the compression spring; a regulator piston exposed to the low-pressure chamber and in contact with the regulator ball valve, wherein when a pressure within the low-pressure chamber lowers past a predetermined pressure, the regulator piston is biased by a primary regulator spring to push the regulator ball valve from the closed position to an open position wherein air flows from the high-pressure chamber to the low-pressure chamber until the pressure within the low-pressure chamber reaches the predetermined pressure; and a regulator piston support nut exposed on the surface of the outer housing and configured to adjust the predetermined pressure by adjusting a magnitude of the bias on the regulator piston created by the primary regulator spring; a regulator ball valve positioned between the high-pressure chamber and the low-pressure chamber, the regulator ball valve comprising a regulator ball biased by a compression spring to a closed position against an o-ring wherein airflow from the high-pressure chamber to the low-pressure chamber is minimized; a regulator valve screw exposed on the surface of the outer housing and configured to adjust a magnitude of the bias on the regulator ball created by the compression spring; a regulator piston exposed to the low-pressure chamber and in contact with the regulator ball valve, wherein when a pressure within the low-pressure chamber lowers past a predetermined pressure, the regulator piston is biased by a primary regulator spring to push the regulator ball valve from the closed position to an open position wherein air flows from the high-pressure chamber to the low-pressure chamber until the pressure within the low-pressure chamber reaches the predetermined pressure;
