Abstract: A firing device of a side-handle baton includes first and second shaft portions, a magazine portion, a trigger housing, a gas chamber portion, and a nozzle portion. Pressure from a CO2 cartridge in the second shaft portion enters and accumulates in the gas chamber portion to push a nozzle. Once a pushbutton of the magazine portion is pressed, ball-shaped bullets in the magazine portion fall into a bore of the first shaft portion, and the magazine portion pushes a trigger in the trigger housing, thus driving a sear to release the nozzle. When a piston rod in the nozzle is freed, the pressure in the gas chamber portion is discharged to fire the bullets. A recoil spring then pushes the nozzle portion back to re-seal the gas chamber portion, allowing pressure to accumulate again in the gas chamber portion, and the sear to retain the nozzle until the next shot.

Abstract: The present invention relates to a gun for using compressed gas to propel an arrow. The gun comprises a hollow barrel adapted to accommodate the arrow. The barrel has an open rear end and an open front end. The gun also includes a cylindrical chamber having a front end through which the barrel extends, a closed rear end, and a gas inlet for connecting the cylindrical chamber to a source of compressed gas. The cylindrical chamber is adapted to hermetically enclose the open rear end of the barrel and is axially movable between a non-firing position where the closed rear end of the cylindrical chamber sealingly engages the open rear end of the barrel, and a firing position where the closed rear end of the cylindrical chamber is displaced from the open rear end of the barrel to allow compressed gas to pass into the barrel via the open rear end of the barrel so as to propel the arrow out the open front end of the barrel. The gun has a simple and robust construction, and has a well-balanced behavior during use.

Abstract: A pneumatic paintball marker has, for example, a sleeve that controls the passage of air through the longitudinal barrel or opening within the marker. By sequentially filling separate chambers defined within the opening and the sleeve, the sleeve is able to translate axially through the opening in a sequential manner.

Abstract: The pneumatically powered projectile launching device has a bolt located within a body. A front gas chamber in the body has an opening through which the bolt extends into the chamber. The bolt can move forward and backward thereby changing the volume of the front chamber. The bolt has a backward facing working surface. A gas valve in the body selectively releases compressed gas into the chamber. The released gas applies pressure on the backward facing working surface of the bolt to move the bolt forward, and then passes through a passage in the bolt to pneumatically force the projectile to leave the device. Other embodiments are also described and claimed.

Abstract: This specification discloses a structure of the paintball gun. It comprises a body, a pressuring set, and a triggering set. The body has an axial passage whose front end forms a paintball outlet. The triggering set and the pressuring set are disposed in sequence inside the passage. The triggering set has a bushing, a guide pillar, and a bolt. The bushing is fixed inside the passage. The bolt is mounted on the guide pillar and disposed together inside the bushing. Air after being pressurized by the pressing set enters the triggering set. A control valve controls the flow path of the air in the triggering set in order to push the guide pillar backward. The air thus pushes the bolt toward the paintball outlet of the passage for triggering.

Abstract: A gatling gun style projectile launcher comprising an assembly of rotating, pressurized-air driven guns. A loader assembly mounted on the gun assembly rotates synchronously through mating of drive gears with the assembly of guns. The loader applies centrifugal force to the paintballs within, urging them into loader tubes positioned in the wall of the loader. Synchronous timing gears align the rotating loader tubes with cognate breech openings in the guns, thereby transferring paintballs into the firing positions from which the paintballs are launched.

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 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 the use of tools, and gives the user a convenient carrying handle for holding the paintball marker, which is commonly called a “snatch grip.

Abstract: A volume restrictor can be provided for a pneumatic paintball gun to reduce the volume of compressed gas available within a compressed gas storage area for a firing operation of the paintball gun. In one embodiment, the volume restrictor includes a body having a forward end and a rearward end. A forward sealing member can be arranged on the forward end to seal around a bolt of the paintball gun.

The increased chamber pressure can result in a shorter recharge time and less velocity drop off in successive shots.
