How System Functions
The paintball gun (or paintball marker) fires a 0.68 inch diameter paintball at speeds of around 280 fps using compressed air in a semi-automatic firing style. This means that after cocking the marker once, when you pull the trigger it will fire a paintball and also recock the marker for you. This allows the user to rapidly fire paintballs.
Before you can fire the gun, the bolt must be in the cocked position. This is accomplished by pulling the cocking pin back until you hear a click. This is only done once at the beginning of use. When the bolt is pulled back, the Venturi Bolt slides back in the marker barrel (shown in red) which allows a paintball to fall through the feed neck and into the marker barrel. The cocking pin is also connected to the striker bolt, which slides back in the striker chamber (shown in yellow) engaging the trigger mechanism (the trigger mechanism will be described separately in the next section). When the striker bolt engages the trigger mechanism, it is locked in the back position. This causes the striker spring to apply a force to the back of the striker bolt.
In this cocked position, the air reservoir (shown in blue) is filled with compressed air. This chamber is sealed off from the rest of the gun by the cup seal and valve pin assembly. This assembly is being pressed against the valve body (shown in green) by the valve spring. The valve body has three holes, one into the the air reservoir, another into the striker chamber, and a final leading up into the marker barrel. The valve pin extends through the valve body and into the striker chamber.
When the trigger is pulled, the striker spring pushes the striker bolt forward. The striker bolt strikes the valve pin, which opens the seal the valve pin and cap seal were creating with the valve body. Since the striker bolt and venturi bolt are connected, the venturi bolt also moves forward. Before the venturi bolt reaches the front position, it comes in contact with the paintball and pushes the paintball forward toward the barrel. Since the seal in the air reservior was opened, compressed air flows through the valve body into the striker chamber and the marker barrel. The compressed air that flows into the marker barrel accelerates the paintball out of the barrel, firing the paintball marker. The air entering the striker chamber forces the striker bolt back into the cocked position. At this point the valve spring pushes the cap seal and valve pin back against the valve body, sealing the air resevior again. With everything returned to the cocked position, another paintball falls into the marker barrel and the gun is ready to be fired again. The whole process from trigger pull until the gun cocks itself again occurs in less than a second.
