How a paintball gun works?


Paintball guns are used to simulate battles without injuring people, even though it does sting when they hit you! They are quite fun to use and even have a professional league devoted to it.

A paintball gun works sort of like a real gun, only it uses air pressure to propel the ball. There is a gas tank at the back of the barrel.




 A ball is dropped into the barrel when the bolt moves back. The bolt then sticks to the hammer with a hinge. A spring is compressed in between the two. When the trigger is pulled the hinge releases the hammer and it is propelled by the spring. The hammer hits raised edges on the valve tube and moves it backwards. When the valve tube is moved, holes on its sides are exposed. This allows gas to travel through the valve tube to reach the paintball. The valve tube strikes the cup seal when it moves back and exposes its holes. The cup seal stops the gas from flowing into the valve tube. A spring at the back of the cup seal pushes the cup seal and the valve tube back to their original positions. When the gas is released for that split second it travels through the valve tube towards the paintball and pushes it out of the barrel. It can do this because the pressure of the gas is greater than the air on the other side of the paintball. The valve seal makes sure no gas escapes, and maintains the gas pressure. (Harris)
When projectiles are moving through the air many factors affect how it will fly and how far; such as the initial velocity, or the force applied to the projectile to make it move, gravity, the angle it was directed, air friction, wind, the spin of the projectile, and probably some that I don’t know about.
