  • Publication number: 20090064981
    Abstract: A paintball marker has an inline cylinder that includes a gas governor that reduces gas flow from a compressed gas source to a valve area when the bolt is in a firing position; this increases efficiency in the marker because only the required air is used to fire the paintball. This bolt operates independent of the valve pin, which increases cycle speed and enables the governor to open and close at an optimum time in the firing cycle. Further, when the bolt/piston is recocking, the gap between the valve pin and governor valve pin enables low pressure gas driving the piston to start pressurizing the cylinder and driving the piston rearwards without resistance from the high pressure gas. The marker also allows a user to remove the inline cylinder without tools, and provides a convenient carrying handle for holding the paintball marker, which is commonly called a “snatch grip.

  • Patent number: 7451680
    Abstract: A steam generator missile ejection system has a vessel that contains water that becomes the pressurized steam source for missile ejection. A heating system within the vessel heats the water to steam and to the desired launch pressure. The heater is controlled to sequence operation and heat generation with a command from a controller shortly before initiation of a firing valve. A valve controls piping from the vessel to direct steam to a piping header and onto the ejection chamber of a launch tube. This event provides the launch pulse required to eject the payload from the missile tube. The launch energy requirements can be modulated by varying the pre-launch temperature of the water in the pressure vessel and can be controlled by an opening rate and length of open duration of the valve.

  • Patent number: 7313881
    Abstract: A pneumatic launcher has a plenum chamber section, an intermediate chamber section and a launch tube section connected together in a generally linear arrangement. The plenum chamber section defines a plenum chamber that has a closed end and an open end. The intermediate chamber section has aft and forward rupture disks consecutively arranged to define an intermediate chamber. The plenum chamber is pressurized with a pressurized gas to a design plenum pressure and the intermediate chamber is pressurized with a pressurized gas to pressure that is about one-half the design plenum pressure. The intermediate chamber is then depressurizing to produce a pressure imbalance between the plenum and intermediate chambers that causes said aft and forward rupture disks to rupture. As a result, pressure equilibrium occurs between the plenum chamber and launch tube thereby discharging the fluid and projectile from the interior of the launch tube.

The bolt comprises an axial channel admitting compressed gas through a radial intake port in the proximal section of the bolt and leading the gas through a elbow-zone and an axial portion to a discharge port at the leading edge of the bolt. A sleeve slidingly engaged over the bolt as a radial aperture which is maintained in line with the intake port by a compressible coil spring, and has a leading portion extending ahead of the bolt. When the firing mechanism translates the bolt and sleeve to place the intake port and aperture in line with a gas-supplying outlet, any obstruction in the gun barrel upon being contacted by the leading edge of the sleeve, causes the sleeve to resiliently slide backward. The misalignment of the aperture and intake port prevents gas from expanding through the bolt channel and into the gun barrel.

  • Publication number: 20030221684
    Abstract: A paintball gun trigger system includes a trigger, an emitter arranged to emit light and collector arranged to receive an amount of the light that varies with the position of the trigger and produce a signal that varies with the position of the trigger. A controller is arranged to determine from the signal when the trigger has been pulled and released. In one embodiment, the light beam from the emitter is pulsed on and off and the signal from the collector is sampled at regular intervals. Variations in the pulsed collector signal are used to detect when the trigger has moved to a pulled position and a released position, and when the collector is swamped with light from another source.
