US12422055 - Pneumatic actuation valve assembly
The pneumatic actuation valve assembly is designed to control the movement of a main spool that actuates a bolt to chamber and eject projectiles based on fluid pressure changes during an operating cycle. It includes components such as a timing spool, spring, and magnet to facilitate the precise timing and actuation of the firing mechanism.
Claim 1
- A pneumatic actuation valve assembly comprising: a frame having a bore axis; a timing spool received in the frame and adapted to reciprocate along the bore axis; a timing spring carried by the timing spool configured to bias the timing spool in a forward position at a first phase of an operating cycle; a main spool received in the frame and configured to travel along the bore axis toward a frame forward position wherein the main spool actuates a bolt carried by the frame and configured to receive a projectile in an open position and chamber the projectile in a closed position; and, whereas the timing spring is configured to transition rearward upon an application of a pressure at a second phase of the operating cycle thereby ejecting the projectile. a frame having a bore axis; a timing spool received in the frame and adapted to reciprocate along the bore axis; a timing spring carried by the timing spool configured to bias the timing spool in a forward position at a first phase of an operating cycle; a main spool received in the frame and configured to travel along the bore axis toward a frame forward position wherein the main spool actuates a bolt carried by the frame and configured to receive a projectile in an open position and chamber the projectile in a closed position; and, whereas the timing spring is configured to transition rearward upon an application of a pressure at a second phase of the operating cycle thereby ejecting the projectile.
