Ok well this started for a design for a semi auto pneumatic cannon ("spudgun") but this will be alot easier to machine as a smaller scale.
1. Filling
The air from the compressor (70-80 psi) goes thru the small virticle pipe and pushes down on the piston and going thru the other virticle pipe to fill the chamber area around the bolt(red)
2. Exhausting
The 2 Blueish rectangles with RED dots are small solenoid valves that are put on ONE switch to trigger them both at the same time. When the Solenoid(right,red) is triggered air rushes behind the piston, and acompanies the spring(bottom,purple) and forces the piston to seal against the verticle seat sealing off input air from the chamber. The other solenoid(left) exhausts air in front of the disc/plate and the air behind it forces the bolt forward letting the air rush thru the center hole (Bright purple lines thru the bolt) and out to the projectile.
3. Refilling
The last solenoid (yellow dot) is opened after all the air in the chamber area has been exhausted and the spring(not drawn see below) has assisted the bolt to return to the sealed position. When the Solenoid (yellow dot) is opened the air behind the piston is exhausted letting it move back and letting input air to move around the bolt and into the chamber area around the bolt.
The spring would be put infront of the disc with the oring on it towards the front, it would push against the front part of the gun.
The black things are orings, the horizontal real small lines are bleed holes.
AIM ohspyro89 for any questions and suggestions.
Im really looking for some easier answers for the front filling/exhausting assembly. The one i have drawn now would take up space and would cost alot of money for the solenoids. Plus the assembly would be bulky and add un needed weight. I was looking at 3-way solenoids but never got a full understanding on thier workings.
