Transcript of Paintball Pneumatic System

Component Identification
The reservoir of a paintball gun is its gas tank. It holds all of the excess gas and uses it when needed. This is usually on the bottom of the gun and the usual CO2 gas tanks are at 800 psi. Some more advanced ones are at 1100 psi.
The compressor is the part of the gun that lets out the air/gas when it is needed. It lets out a constant 800 psi until the air tank is empty and then the system can’t be used until the tank is refilled. the compressor is activated when the trigger is pulled on the gun. Also keeps the gas with in the tank compressed and good to use until it is all gone.
The valve is in the barrel and resets a paintball when one is shot. In most guns they reload themselves pretty fast almost as soon as you pull the trigger and the valve controls when and how fast the paintball goes into the chamber.
The cylinder doubles as the reservoir since it holds the air and the reservoir holds the excess of the air. The cylinder holds the air that is ready to be pushed out to shoot the paintball.
System Operation
Paintball guns quickly thrust and propel paintballs out of the gun via a burst of compressed air. A long valve is in the center. The valve tube runs the length of the barrel down into the chamber which is located at the rear end of the gun. This is also where the gas cartridge is attached. The valve tube passes through the bolt, the hammer and a spring along this path. It also passes along the valve seat which is located at the gas-intake end position of the gun. The valve tube is at all times open at the barrel end of the gun. However, the other openings that are at the sides of the tube are obstructed by the bordering valve seat. The tube is kept in place by a device referred to as a cup seal. When the gun is not cocked, the bolt expands and blocks the paint balls from entering through the barrel. To shooter must cock the gun to release and shoot the paint balls. This is done by pulling the bolt backward on the gun and pressing the spring to get the bolt to hit against the hammer. As the bolt slides backward, the ammunition intake opens allowing a paintball to enter the barrel of the gun. A device referred to as the sear is located at the bottom of the hammer. The sear spins on a small pin and latches onto the bolt once the bolt is pressed against the hammer. The sear also causes the hammer and the bolt to connect resulting in their working together as one component. Once the shooter pulls back the bolt, the hammer is also pressed forward. The trigger is pulled to fire the gun causing the trigger to press against the rear portion of the sear. This motion causes the front end to move down freeing the hammer from the bolt causing the hammer to spring and propel swiftly backward. When the hammer springs backward, it presses against a raised device surrounding the tube. The valve tube is propelled backward with great force and is pressed back momentarily. The spring pushes the valve tube back into position causing the sides of the tube to be exposed. The pressurized gas is able to stream through the barrel at this time resulting in a paintball being propelled forward out of the paintball gun at a high velocity of speed.
Reflection
This device is a good recreational use of the pneumatic system. It uses the trigger to release air into the chamber to shoot the paintball down the barrel. That is pretty simple use of the system but a good use of it and pretty lightweight. This device is fun to use and pretty easy to assemble and even upgrade if wanted to. Also it has 2 versions -mechanical and electropnuematic- which make it either more efficient with the air or simpler to upgrade
Device Description
A paintball gun (formerly known as paintball marker). Paintball guns use expanding gas, such as compressed air or carbon dioxide, to shoot paintballs from the barrel of the gun. There are two types of paintball guns - mechanical and electropnuematic. A mechanical paintball gun is one that shoots less accurately and shoots a lot slower than an electropnuematic one. The electropnuematic one uses less compressed gas and shoots faster due to less pressure needed for the trigger to be pulled. Also the electropnuematic uses a micro switch when pressed to activate a circuit board to tell the gas to release in turn shooting the paintball.
