20100199963PAINTBALL GUN - A paintball gun includes an air valve and a body portion, in which the body portion includes a paintball hole, a communicator, a piston, an axle sleeve and a bolt. By the pneumatic control of the air valve, the piston is pushed between the first and second positions, and the movement of the bolt is, therefore, controlled between the third and fourth positions, so as to selectively turn the effusion passage open or closed to control the pneumatic air to flow out of the projection passage and projection hole to project the paintball.08-12-2010
20090145414PNEUMATIC LAUNCHER - A pneumatic launcher includes a number of chambers for holding a compressed gas and a valve for releasing the compressed gas into a firing chamber to fire a projectile. The firing valve may include a number of surfaces on which pressure acts to slide a sliding valve body between an open position and a closed position. The launcher may include a recess for preventing pressure from acting on one of those surfaces when the valve is in the closed position. A part of the sliding valve body may interact with adjacent parts to form a closed region ahead of the sliding valve body, in order to cushion motion of the sliding valve body. The launcher may have a breech and a breech pin shaped to create a desired gas flow within the firing chamber during firing. The breech may include a breech pin seal which seals between two faces oriented transverse to the axis of the launcher. The launcher barrel may have a number of ribs for improved stability and accuracy.06-11-2009
20120145138VARIABLE PNEUMATIC SEAR FOR PAINTBALL GUN - An improved paintball gun uses a low-pressure pneumatic sear to hold the firing valve closed against the high pressure gas occupying the other side of the valve. In this manner, only one operation is required between depressing the trigger and the firing of the paintball gun because a double-acting cylinder is not required as an interface between the trigger depression and actuation of the valve. The paintball gun is also substantially faster than existing electro-pneumatic paintball guns because it uses a blow forward bolt, in which higher-pressure gas is held directly behind the bolt and has only one direction to travel during the firing of the paintball gun.06-14-2012

20110088675BOLT AND VALVE MECHANISM THAT USES LESS GAS - The proposed invention is a new bolt and gas release valve mechanism for a projectile launching device, such as a paintball marker, that uses significantly less gas per shot than prior art devices. The open gas chamber between the projectile, such as a paintball, and the gas release mechanism is eliminated thereby requiring much less gas to be used for each launch of a given projectile. Thus, only the launching gas to propel the projectile is needed and not the additional gas required to fill the chamber in the bolt directly behind the projectile. This enables desirably smaller gas supply tanks to be used during use to launch the same number of projectiles. Also, with the present invention, more projectiles can be launched using the same gas supply tank.04-21-2011

In an exemplary embodiment, a paintball marker generally includes a housing including a wall defining a chamber having an axis and an open end. A valve assembly is within the chamber. The valve assembly may be coaxial with the chamber. The valve assembly may be configured for rotation about the axis of the chamber. The valve assembly may be configured to seal compressed gas while at rest and configured to seal and release compressed gas while in motion. Additionally, or alternatively, the revolving valve assembly may have a start position and a stop position which is located one revolution from initial movement out of the start position.09-13-2012
20090056693PROJECTILE LAUNCHING APPARATUS - Disclosed is a projectile launching apparatus capable of launching a projectile, such as a pellet, a BB, an arrow, a dart and a paintball. The projectile launching apparatus includes a motor driven linear motion converter, a cylinder, a breech assembly and a compression valve arrangement. The linear motion converter converts a rotational movement of a motor into a linear movement of a piston by a gear reduction mechanism. The linear movement of the piston within the cylinder compresses a gas with a high compression exponent. The compressed gas is further released into a barrel of the breech assembly through the compression valve arrangement. The compressed gas expands in the barrel causing a projectile to be launched from the barrel with a force of the compressed gas.03-05-2009
20110265775Toy gun - A valve body is in a cylindrical shape and communicates with the rear-side end of a barrel on the front side. The valve body forms an air chamber therein. A discharge valve is positioned in the valve body. The discharge valve is hit by a bolt from behind and thereby opens or shuts the communication between the barrel and the air chamber. When the bolt makes forward or backward slide movement, the valve body is fit into a first opening at the front part of the bolt. The cylindrical portion or the closed end of the bolt is provided with a second opening through which the air in the bolt flows in or out.11-03-2011
20120090586BOLT AND VALVE MECHANISM THAT USES LESS GAS - The proposed invention is a new bolt and gas release valve mechanism for a projectile launching device, such as a paintball marker, that uses significantly less gas per shot than prior art devices. The open gas chamber between the projectile, such as a paintball, and the gas release mechanism is eliminated thereby requiring much less gas to be used for each launch of a given projectile. Thus, only the launching gas to propel the projectile is needed and not the additional gas required to fill the chamber in the bolt directly behind the projectile. This enables desirably smaller gas supply tanks to be used during use to launch the same number of projectiles. Also, with the present invention, more projectiles can be launched using the same gas supply tank.04-19-2012
20120325192Method and Apparatus for Controlling Paintball Loading Using a Detent - A paintball assembly capable of retaining a paintball in a loading chamber using a paintball catcher is disclosed. The paintball assembly includes a loading chamber, a detent, and a bolt. The loading chamber is coupled to a loading port to receive paintballs. In one embodiment, the detent includes a paintball catcher capable of catching the paintball as it is loaded into the loading chamber. In one example, the paintball catcher is a flexible paintball catcher extending into the loading chamber and is able to catch the paintball and hold it in a predefined position. When a trigger is pulled, the bolt pushes the paintball into a firing chamber while the paintball catcher releases the paintball.12-27-2012
20120138037EZ-LAUNCH TWO LITER POP BOTTLE LAUNCHER - A toy rocket launcher is adapted to pressurize a container, such as a two-liter bottle, and launch the pressurized container upon release of an internal release mechanism, The internal release mechanism locks the bottle rocket in place and releases it with a slight pull on a string. A tire valve may permit a user to pressurize the container with an air pump, such as a bicycle pump or an air compressor. An optional pressure gauge may be provided to monitor pressure in the container.06-07-2012
20100288256COMPRESSED GAS POWERED PROJECTILE GUN - A compressed gas gun fires arrows or other similar projectiles. A compressed gas delivery mechanism within the compressed gas gun ensures that a predetermined amount of compressed gas is used to fire an arrow during a firing operation. Various elements within the compressed gas gun can be selectively tailored to provide greater or lesser amounts of compressed gas during each firing operation.11-18-2010
20100313866Firing Structure of Paintball Marker - A firing structure of a paintball marker includes a marker body and a firing cylinder. The marker body includes a barrel with mutually communicating first and second gas chambers. A stop edge is formed in the barrel at a junction between the first and second gas chambers. An O-ring is embedded in an inner wall of the barrel at a position inside the second gas chamber. The firing cylinder and a rear guide rod are put sequentially into the gas chambers. The firing cylinder has an outer periphery formed with a stop portion in the first gas chamber. The stop portion has a front edge mounted with a buffer washer corresponding in position to the stop edge of the barrel and having a planar surface. Thus, the process yield of the marker body can be increased, and the firing cylinder remains stable in high-speed action regardless of its position.12-16-2010
