Background info
What happens when you pull the trigger?
Background Info
-First half or trigger pull is to fire, second is to recock
-The middle tube on the 3-way is the supply line of air that supplies the left and right tubes with air (always open with one tube) which comes from the regulator.
-Air enters the gun at around 1200-1300 psi. It is regulated and brought down to 700-800 psi. The air going to the 3-way is regulated again and brought down to 90 psi.
-The marker shoots like all others by that when the sear is released it hits the valve for a brief moment which releases air and send the ball flying.
How It Works
1st Half of the Trigger Pull
This is how the marker looks when it is ready to fire. Notice how the ram is in the forward position.
2nd Half of the Trigger Pull
When you move the trigger the last half it pulls on the timing rod. The timing rod pulls the 3-way valve back and lets air into the left tube (cuts off the air supply from the right tube). The left tube is connected to the front of the ram. When this happens air can now travel to the front of the ram pushing the piston from the forward position to the back position which send the back block in the back backward (see diagram)
Trigger Returning Forward
Now an opposite reaction happens. As you move the trigger forward it pushes the timing rod. The timing rod pushes the 3-way valve which moves forward closing the left tube and opening (exposing) the right tube. When this happens the air is now moving toward the right which (the tube) is sent to the back of the ram. This air pushes the piston forward, which returns the back block forward also. As the striker moves forward it catches on the sear and is now in the ready position again.
And that's it, easy huh?
