Abstract
A projectile launching system for pneumatically launching projectiles is disclosed. The projectile launching system includes a nozzle that is positioned within an engine body and movable between a rearward, loading position and a forward, firing position. A valve stem contained within the engine body is moveable to selectively control the discharge of pressurized gas to propel the projectile. The movement of the valve stem controls the supply of pressurized air to move the nozzle to the rearward, loading position upon firing of a projectile. A trigger assembly is used to selectively control the venting of pressurized air to atmosphere to control the movement of the valve stem within the projectile launching system.
