  • Patent number: 6675791
    Abstract: An improved pressure regulator for pneumatic guns, with an improved and simplified design incorporating a rotating gas fitting with a gas inlet port; modular construction to allow fitting to different pneumatic guns/air sources/configurations; better pressure output stability at pressures lower than 200 psi; and improved ease of maintenance. There is also a sliding, externally actuatable check valve for pneumatically isolating one pneumatic component of the paintball gun from another pneumatic component.

  • Patent number: 6523534
    Abstract: An electric firing controller for a lacquer bullet gun, comprising a power circuit, a lighting circuit indicating power turned on, a closing circuit having a single triggering switch and a capacitor, and an electromagnetic control unit. By operating the single triggering switch, the electromagnetic control unit is connected with the capacitor, discharging the capacitor and causing the electromagnetic control unit to trigger firing of a single lacquer bullet. In an extension of the present invention, automatic firing of lacquer bullets is controlled by repeated charging and discharging of the capacitor, as controlled by a pulse generator and a relay. Thus precise firing of lacquer bullets with little physical effort is controlled in an inexpensive way.

  • Patent number: 6474326
    Abstract: The pneumatically operated projectile launching device is preferably comprised of three principal elements: a body which houses and interconnects all of the pneumatic components and also houses the electrical power source, a grip mounted to the body which includes an electrical switch 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 bores in communication with each other including a bore containing and distributing pressurized gas, a bore containing a compressed gas storage chamber and mechanisms for filling the storage chamber with gas and releasing gas from the storage chamber to fire the projectile, and a bore containing mechanisms for loading and launching the projectile.
