    摘要： An evaporative barrel cooler for a firearm includes a firearm adapter having a mist nozzle, and a high pressure coolant reservoir attached to the firearm adapter with a flexible hose. The firearm adapter orients the nozzle inside a firearm chamber and aligned with the bore of a firearm barrel. The firearm adapter conforms to the interior of a firearm action and replaces a firearm bolt. The firearm adapter accesses the chamber through an open action port or through the bolt's raceway. The high pressure coolant reservoir may further include a hand pump attached to the reservoir for pressurizing the coolant. A coolant valve may be incorporated into the flexible hose to control the flow of coolant, whether it is water, alcohol, gunpowder or bullet metal solvent, or a nonflammable and nonreactive material.

    摘要： A light armor piercing weapon, which is hand carried by a single man, is provided for firing or launching armor piercing rocket propelled projectiles. A propellent pack is worn or carried by the soldier along with a launching rifle. Unsymmetrical dimethylhydrazine is provided as a propellent and inhibited red fuming nitric acid, Type IIIa, is provided as an oxidant in a combustion chamber in the rifle. The explosive combination of the propellent and oxidant propels the projectile out of a smooth bore barrel and simultaneously ignites the solid propellent in the projectile. The projectile is provided with a disposable sabot which seals the projectile within the smooth bore. The projectile is provided from a spiral drum magazine which is gear driven by a mechanical coupling with a reciprocating breech block within the rifle. The reciprocating breech block in turn is gear driven by a gas driven piston communicated with the barrel. A ramming rod is also gas driven from the barrel to dispose the projectile into the breech block synchronously with reciprocation of the block. Coolant in a closed loop cooling system is pumped through the rifle by the reciprocating action of the breech block, which has pumping chambers which are effective upon reciprocation of the block. The coolant is used to cool the breech block and the combustion chamber within the rifle. Excess heat from the coolant is transferred to the ambient environment by an air-to-coolant heat exchanger carried in the propellent pack. The rifle butt is provided with a hydraulic recoil shock absorber. The barrel is provided with a muzzle brake and flash hider. The initial round is mechanically cocked and a manual unloading mechanism is provided to eject an unlaunched projectile.

    摘要： In order to cool the barrel inner wall of a weapon barrel of a firing weapon at a predetermined location, typically at the rear end region of the weapon barrel, one or more cooling fluid channels are arranged at the barrel wall of the weapon barrel. The cooling fluid channels open at the barrel inner wall. By means of an apparatus which can be actuated by the gas pressure of the propellant gases, there is injected into the interior of the weapon barrel a dosed quantity of cooling fluid after the firing of each cartridge or ammunition round. This apparatus preferably comprises a piston arrangement having a first piston of larger diameter and which is subjected to the gas pressure of the propellant gases and a second piston of smaller diameter at which impinges the cooling fluid.
