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. The electrical control unit preferably includes an electrical power source which activates an electrical timing circuit when the electrical switch is closed, and two electrically operated pneumatic flow distribution devices which are sequentially energized by the electrical timing circuit to enable the loading of a projectile for launching and to release compressed gas from the storage chamber to fire the projectile, respectively. Before the initiation of a launching sequence the compressed gas storage chamber is filled with compressed gas while the projectile launching mechanism is disabled. Filling of the compressed gas storage chamber is preferably accomplished automatically by actuation of the compressed gas filling mechanism. When the electrical switch is closed to initiate the launching sequence the projectile is first loaded into the launching mechanism by electrical timing circuit actuation of the first electrically operated pneumatic flow distribution device. The projectile is then fired when the electrical timing circuit actuates the second electrically operated pneumatic flow distribution device to release gas from the compressed gas storage chamber into the launching mechanism.
An electronically controlled pneumatic paintball gun, comprising means for monitoring and/or controlling one or more parameters of the gun's operation and alphanumeric display means for displaying data related to said monitoring or control on a display panel integral with the gun.
A paint ball gun is connected through a first gas pressure regulator to a supply of pressurized gas for maintaining a high gas pressure in a first chamber in the gun and a second gas pressure regulator is connected between the first chamber and a second chamber in the gun to maintain a working gas pressure in the second chamber greater than atmospheric pressure but less than the gas pressure in the first chamber. A pneumatic control valve is arranged to receive gas under pressure from the second chamber and direct it selectively to a pneumatic ram mounted for sliding movement in a cylinder in the gun between a retracted position and a forward position in which it opens a valve to admit high pressure gas from the first chamber to the barrel to fire a paint ball. An electrical switch for the control valve is connected to an electronic control circuit which incorporates a micro-switch operated by the trigger of the gun.
An electrically operated paintball gun operable to shoot paintballs including a barrel, a trigger, and a breech connected to a rear end of the barrel, as well as a bolt movable in the breech between a rearward position and a forward shooting position. A spring biases the bolt towards the rearward position. A pneumatic circuit is provided to drive the bolt towards the forward position and includes a control valve in the form of a solenoid valve to receive gas under pressure and direct it into a chamber at the rear of the bolt when the gun is shot. An electronic circuit controls the pneumatic circuit and is operated by an electrical switch operated by the trigger. A gas valve mechanism is opened by engagement by the bolt, when the latter is driven forwardly to the shooting position, to permit the passage of relatively high pressure propellant gas into the barrel to propel a paintball. The spring is preferably mounted in a longitudinal passage in the bolt and is held at its front end by a fixed spring engaging member located in the passage.
The pneumatic launching assembly includes a launching body with a front end and a rear end. A first chamber is positioned in the rear end of the launching body for isolating a gas supply. A bolt is positioned in the front end of the launching body for moving a projectile into a launching position. A second chamber is coaxially forward of the first chamber for isolating the gas supply until the bolt is in a fully forward position. A firing plunger is slidably mounted in the launching body and moveable within the bolt and first chamber for regulating gas flow. In operation, the bolt moves forwardly to position the projectile into a launching position, meanwhile, the firing plunger moves rearwardly to release an gas to propel the projectile. The bolt and firing plunger are coaxially moving in opposite directions to minimize any recoil of the pneumatic launching assembly.
A device for assisting a user in marking an overhead surface to correspond with a mark on a surface below includes a substantially hollow housing having pressurized gas containers received therein. The pressurized gas containers are in communication with a projection barrel extending upwardly from the housing. A lower laser module is positioned on the lower surface of the housing for projecting a laser beam downwardly onto a target mark on an underlying surface. The paint ball projection barrel is coaxial with the lower laser module such that when the laser beam is directed toward the target mark, a paint ball can be projected upwardly to produce an overhead mark that is axially aligned with the target mark.
