<p>The pneumatically operated projectile launching device is preferably comprised of three principal elements: a body (40) which houses and interconnects all of the pneumatic components and also houses the electrical power source (33), a grip mounted to the body which includes an electrical switch (30) that activates a launching sequence, and an electrical control unit housed within both the body and the grip which directs flow between the pneumatic components to load, cock and fire the gun. The body preferably contains a plurality of chambers (1) in communication with each other including a chamber (2) containing and distributing pressurized gas, a chamber (11) containing a compressed gas storage chamber and mechanisms (12, 13) for filling the storage chamber with gas and releasing gas from the storage chamber to fire the projectile, and a chamber (3) containing mechanisms for loading and launching the projectile (41). The electrical control unit preferably includes an electrical power source (33) which activates an electrical timing circuit (34) when the electrical switch (30) is closed, and two electrically operated pneumatic flow distribution devices (35, 36, 37) which are sequentially energized by the electrical timing circuit to enable the loading of a projectile (41) for launching and to release compressed gas from the storage chamber (11) to fire the projectile, respectively.</p> |
