A variable velocity pneumatic launcher including at least one chamber filled with a projectile. The launcher includes a ballast chamber filled with pressurized air selectively released to propel a projectile from the launcher's barrel. The launcher includes a firing chamber filled with ambient air and a ballast chamber filled with pressurized air. A piston rod extends between the chambers and attaches to a firing piston and a ballast piston located inside the firing chamber and ballast chamber, respectively. The rod is connected to an adjustable velocity valve which controls the amount of longitudinal movement of the rod. When the trigger is activated, a portion of the pressurized air from the ballast chamber is delivered to the firing chamber. Because the surface area of the firing piston is greater than the ballast piston's surface area, the force exerted on the firing piston is sufficient to shift or displace the ballast piston and allow pressurize air to be released into the upper chamber containing the projectile.

A projectile accelerating control system that includes a projectile accelerator and/or associated projectile equipment configured to provisionally lower the velocity and/or energy level, where said provisionally lower level is below the set upper velocity and/or energy limit. One aspect or feature of said accelerating system includes a means that indicates the amount of reduction from the upper velocity and/or energy limit. The accelerating control system includes adjustment mechanisms and/or methods that allow the impact energy of a projectile to be reduced from the upper impact limit associated with the upper velocity and/or energy limit. The accelerating control system includes adjustment mechanisms and/or methods that include a controller configured to allow the selective selection of a velocity and/or energy levels that fall below a upper velocity setting and/or energy level. Where the said upper velocity setting and/or energy level is a setting or level that falls below the maximum velocity and/or the maximum energy level of the projectile accelerator.

A gas-powered gun for discharge of projectiles, comprising a pressure chamber for holding compressed gas, a valve arranged to release compressed gas from the pressure chamber to thereby discharge a projectile provided in a barrel, and a plenum chamber in fluid connection with the pressure chamber. The plenum chamber is formed coaxially around a rear portion of the barrel.

A valve system utilizes a main valve body with a restricted diameter conduit communicating between a propulsion chamber and rear cavity and a smaller venting valve mechanically actuated to open the rear cavity to atmosphere, thereby causing the main valve body to open to pass pressurized air in the propulsion chamber to an orifice to power a projectile. The orifice has a diameter at least as large as the dimeter of the projectile.

A pneumatic regulator assembly for a paintball marker includes a first body portion with a connector at one end for attachment to a paintball marker, a second body portion with a connector at one end for attachment to a compressed air canister, and a collar coupled between the two body portions at ends opposite the connectors for each. The collar allows the second body to rotate relative to the first body portion.

An in-stock compressed gas delivery assembly to deliver gas to an airsoft gun, including a cartridge receiving portion to receive at least a portion of a compressed fluid cartridge, a locking cap to secure the compressed fluid cartridge in the gas delivery assembly, a puncture pin assembly to puncture a nozzle of the compressed fluid cartridge when the locking cap is closed over the cartridge, a regulator to regulate a volume of gas passing from the gas delivery assembly, and a plurality of expansion chambers configured to form a tortuous path, between the cartridge and the regulator, to expand liquid from the compressed fluid cartridge to gas, and a buffer tube having a first end configured to be coupled to the airsoft gun; and a second end configured to receive the gas delivery assembly such that the buffer tube houses at least a portion of the gas delivery assembly.

A pneumatic air gun including a gun support, a barrel disposed on the gun support, a valve body, a pressure gauge, an air compression assembly, an energy storage assembly, and a triggering assembly. The air compression assembly is connected to the energy storage assembly, and the energy storage assembly is connected to the valve body. The triggering assembly includes a trigger support fixed to the gun support and a pull-bolt assembly, a trigger, a trigger button, and a hammer disposed on the trigger support. A spring is attached to the hammer. The trigger is connected to the trigger button. A loading thimble in the pull-bolt assembly slides on the gun support. The loading thimble is movably connected to the hammer and is adapted to control the hammer to reset and to be clamped on the trigger button.
