We are going to start a series of articles on the types of airguns, their calibers and the ammunition used by these weapons, today we are going to start with spring airguns.
Spring-actuated airguns are also known as spring pistols or guns, or Springer. These types of weapons work with a spring that is contained within a compression chamber that is separated from the barrel of the weapon. Historically, the spring used for this type of weapon is a helical or helical spring, made of steel and lubricated with grease, forming the main driving part of the motor silver of the airgun.
Form of Use.
In order to fire this type of compressed air weapon, the user must do it manually each time he wants to use it, cocking the weapon with the lever that is incorporated into the pump, then the piston is pulled in the appropriate direction and the spring is compressed until make sure the rear of the piston is felt to engage properly in order to fire.
The action of Shooting.
When the user squeezes the trigger the pawl disengages and allows the spring to release and decompress rapidly, releasing the accumulated energy and pushing the piston forward, in such a way that the air is compressed in the cylinder, then the outlet of the The pump behind the pellet receives high pressure compressed air that propels it at high speed through the gun barrel.
All this operation is executed in fractions of a second, in this process the air is heated to hundreds of degrees and then cools as it expands. This can also cause a phenomenon known as “dieseling”, where flammable substances in the compression chamber can be ignited by the heat of compression as in a diesel engine, and produce an afterburner effect with additional thrust.
This often results in combustion smoke coming out of the muzzle and potential pressure damaging the rubber O-ring seals within the gun. Diesel can be made to occur intentionally to increase horsepower by coating the pellet with lubricant or petroleum jelly, although this is normally not recommended as it can result in more severe damage to the rubber seals.
