Pneumatically operated projectile launching device
View Patent ↗A pneumatically operated projectile launching device preferably comprises an electro-pneumatic flow distribution mechanism that receives and directs compressed gas to a pneumatic mechanism to open a bolt.
1. A pneumatically operated projectile launching device, comprising:
a compressed gas source;
a bolt physically communicating with a pneumatic mechanism;
an electro-pneumatic flow distribution device having an input connected to the compressed gas source to receive compressed gas into the electro-pneumatic flow distribution device, and an output connected to a first area communicating with a forward end of the pneumatic mechanism such that compressed gas supplied to the first area through the electro-pneumatic flow distribution device drives the bolt to a rearward position.
2. A launching device according to claim 1 , wherein the pneumatic mechanism is coupled to the bolt through a mechanical linkage.
3. A launching device according to claim 2 , wherein compressed gas supplied to a rearward end of the pneumatic mechanism drives the bolt to a closed position to prevent loading of projectiles into the launching device.
4. A launching device according to claim 1 , wherein the electro-pneumatic flow distribution mechanism comprises a solenoid valve.
5. A launching device according to claim 4 , wherein the launching device is a paintball gun.
6. A launching device according to claim 5 , wherein the pneumatic mechanism comprises a pneumatic piston and cylinder assembly, and wherein the bolt is connected to the pneumatic piston.
7. A launching device according to claim 6 , wherein the bolt is connected to the pneumatic piston through a mechanical linkage.
8. A launching device according to claim 6 , wherein the electro-pneumatic flow distribution device comprises a solenoid valve, and wherein the solenoid valve comprises a solenoid valve port connected in fluid communication with a forward end of the pneumatic piston to open the bolt.
9. A launching device according to claim 8 , wherein the solenoid valve port receives compressed gas from the forward end of the pneumatic piston and vents the compressed gas through the solenoid valve to permit the bolt to close.
