US12553684 - Non-lethal gas operated gun

The patent describes a non-lethal gas-operated gun that utilizes a pre-pack assembly containing a gas canister, which connects to a magazine for fluid delivery. It features a gas regulator assembly with a piercing portal, pressure regulator, and poppet valve to control gas flow and enable automatic firing at a reduced operating pressure.

Claim 1

1 . A gas regulator assembly for use with an air gun and a gas canister containing gas pressurized at a canister pressure, the gas regulator assembly comprising: a piercing portal comprising an invasive probe adapted to pierce the gas canister and fluidly couple the gas canister to the piercing portal and a seal adapted to fluidly seal the gas canister and the piercing portal; a pressure regulator assembly comprising a restrictor valve, an inlet chamber and an outlet chamber, wherein the inlet chamber is fluidly coupled to the piercing portal, wherein the outlet chamber is fluidly coupled to the inlet chamber through the restrictor valve and wherein the restrictor valve reduces the pressure of gas passing through the restrictor valve to an operating pressure that is below the canister pressure; a gas storage chamber fluidly coupled to the outlet chamber, wherein the gas storage chamber contains a sufficient volume of gas at the operating pressure to enable automatic firing of the air gun at the operating pressure; a poppet valve fluidly coupled to the outlet chamber, wherein the poppet valve is adapted to provide sufficient gas flow from the outlet chamber and the gas storage chamber to fire the air gun when the poppet valve is actuated. a piercing portal comprising an invasive probe adapted to pierce the gas canister and fluidly couple the gas canister to the piercing portal and a seal adapted to fluidly seal the gas canister and the piercing portal; a pressure regulator assembly comprising a restrictor valve, an inlet chamber and an outlet chamber, wherein the inlet chamber is fluidly coupled to the piercing portal, wherein the outlet chamber is fluidly coupled to the inlet chamber through the restrictor valve and wherein the restrictor valve reduces the pressure of gas passing through the restrictor valve to an operating pressure that is below the canister pressure; a gas storage chamber fluidly coupled to the outlet chamber, wherein the gas storage chamber contains a sufficient volume of gas at the operating pressure to enable automatic firing of the air gun at the operating pressure; a poppet valve fluidly coupled to the outlet chamber, wherein the poppet valve is adapted to provide sufficient gas flow from the outlet chamber and the gas storage chamber to fire the air gun when the poppet valve is actuated.
