Pneumatic launching assembly

A method of operating a pneumatic projectile launcher to launch a projectile, wherein the pneumatic projectile launcher comprises a barrel having a bore therein;

• a trigger mechanism;
• a projectile feed port;
• a breech for positioning the projectile that communicates with the projectile feed port and the barrel;
• a pneumatic valve assembly comprising a pneumatic control valve, a pneumatic gas pressure regulator, a pneumatic gas supply chamber, wherein the pneumatic gas supply chamber receives gas at a fixed pressure from the regulator, a bolt coaxial to the bore of the barrel wherein the bolt slidably communicates with the bore in a forward and rearward positions, the bolt comprising a first forward end and a second rearward end and an internal channel, wherein the bolt is initially secured within the pneumatic control valve assembly in a rearward position by gas from the pneumatic gas supply chamber and wherein the pneumatic gas supply chamber comprises gas, wherein said gas generates a rearward gas force pressure on the bolt to enable the breech to receive the projectile, wherein the bolt includes a bolt sail to generate rearward force from the rearward gas force pressure;
• a valve member in communication with the bolt, wherein the valve member comprises a compliant stop for engaging at least a forward surface of at least one internal ridge in the internal channel of the bolt to create a seal, wherein a forward force acting on the bolt exceeds a maximum holding force of the compliant stop, wherein the trigger mechanism is in communication with the bolt and the valve member and wherein the trigger mechanism communicates with the second rearward end of the bolt through an electronic control board;
• an infeed tube for feeding projectiles into the breech;
• and a device causing a rearward bias of the valve member within the bore, the method comprising:
• a. activating the triggering mechanism to generate a pneumatic bias to the bolt and the valve member, thereby causing the valve member and the bolt to move toward the breech, wherein the bolt and valve member are sealed together by means of their coaxial arrangement, and wherein movement of the valve member enables a flow a gas to communicate with the second rearward end of the bolt, thereby increasing the velocity of bolt actuation;
• and
• b. sealing the projectile infeed tube by movement of the bolt and valve member, wherein the second rearward end of the bolt is dislodged from the valve member by forcing the at least one internal ridge over and beyond the compliant stop, placing the second rearward end of the bolt in pneumatic communication with the pneumatic gas supply chamber to enable the gas to flow in a direct path from the pneumatic supply chamber to the projectile in the barrel thereby projecting the projectile through the bore of the barrel.
