Description

The invention relates to an air pressure speed regulation and shooting cooling device for an automatic weapon gun operation, in particular to an air pressure speed regulation and shooting using an air chamber of a piston to provide an automatic weapon gun for slowing down the operating speed and impact force of the gun and cooling the gun. Cooling device.

In general, the operation principle of individual weapons and automatic weapons can be distinguished between "gas transmission type" and "rear seat type" according to their energy sources. The gas transmission system uses the bullet to launch the moment, and the partial high pressure gas in the barrel is transmitted back to the surface of the piston to act as a kinetic energy for the gun to retreat and complete the automatic cycle, such as the national T91 rifle and the Russian AK-47. Rifles and so on. The rear seat force system uses the bullet to launch the moment, and the reaction force of the bullet acts directly or indirectly on the gun machine, so that the gun machine can complete the automatic cycle, such as the German MP5 submachine gun and the Israeli Uzi submachine gun. In addition, if the recoil force type is matched with the movable barrel design, the recoil energy can simultaneously drive the barrel to collide with the gun to complete the automatic cycle, which is called the "barrel retreat" principle, such as the US M2 heavy machine gun. And M1911 pistols and so on. In the above various ways, the purpose is to exit the empty shell to realize the automatic firing function of the firearm.

At present, the principle of gas transmission is known, which is to control the amount of gas acting on the piston through a gas regulating device, thereby changing the retracting speed of the gun and adjusting the Revolutionary Percent (RPM).

When the user pulls the automatic weapon 2 to move backwards, the extension unit 15 and the piston 14 are synchronously displaced. At this time, the first air chamber 11 and the second unit are slow because the pulling speed is slow. The gas pressure in the gas chamber 12 is less than the elastic force of the compression spring 1422, and a proper gap is maintained between the first assembly 141 and the second assembly 142, and the gas can flow out from the appropriate gap and the air hole 1412.
