20090145414 | PNEUMATIC 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 |
20100199963 | PAINTBALL 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 |
20120145138 | VARIABLE 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 |
20140026878 | PNEUMATICALLY TIMED CONTROL UNIT FOR A GAS OPERATED PROJECTILE LAUNCHING DEVICE - A pneumatically timed control unit controls a gas operated projectile launching device. At rest, the control unit feeds pneumatic gas from a compressed gas supply to the launching device's loading, launching components and/or mechanisms, and/or gas storage chamber(s). Once the valve is partially activated, the control unit uses pneumatic pressure from the gas storage device to urge the valve to a fully activated position to start the launching and/or loading sequences of the launching device and to pneumatically hold the valve(s) within the control unit in the activated position. The control unit waits for pneumatic feedback and/or absence of feedback/exhausting pneumatic pressure from either the launching device's loading and/or launching components and/or mechanism, or from a gas storage chamber and/or a venting relief-type valve to release the pneumatic hold on the valve. This allows the valve to be shifted to the “at rest” position, ready for the next activation sequence. | 01-30-2014 |
20150300770 | Air canister for airsoft gun - A canister of propellant releasably mounted in a stock of an airsoft gun includes a head threadedly secured to a first end of a case and including an intermediate annular groove; a plug threadedly fastened in the head and including first, second, and third O-rings; a plunger disposed through the plug into the head and including a first receptacle, a lateral first opening through the first receptacle, a second receptacle, a lateral second opening through the second receptacle, and an annular flange; a cap threadedly secured to plug and including a bottom opening communicating with the case, and a biasing member biased between a bottom and the flange; a passage member threadedly secured to the case; and a check valve threadedly fastened in the passage member. | 10-22-2015 |
20160123696 | AIR-CHANNEL STRUCTURE OF PAINTBALL GUN - The present disclosure illustrates an air-channel structure of a paintball gun. The paintball gun has a gun handle and a front handle at a bottom portion of a gun body, a front section and a back section of a pipe are disposed inside the front handle and the gun handle respectively, and a center section of the pipe is extended between the front handle and the gun handle. The high pressure gas of the gas tank can be flowed into an air channel inside the gun body via the pipe. The center section of the pipe and the front handle are located at a front side and bottom side of the trigger for use as a trigger guard. | 05-05-2016 |
