A means of creating a novel, balanced, plunger valve. It is designed by combining the valve seats with the valve stem by varying the diameter of the valve stem. While the valve is closed it experiences minimal net force, but once opened, the working fluid assists in minimizing the response time of the valve. This creates a very efficient dump valve. The design limits the number of components needed for the valve to be assembled which reduces the cost, simplifies the maintenance, enhances the strength, and creates a more reliable valve. The following includes several methods of accomplishing this.

A compressed air gun trigger structure, the air refill lock cooperates with the trigger assembly to facility full auto and semi auto shooting. That is while the pressure of the eject chamber is lower than the set scale, the air refill lock will lock the piston even though the trigger is triggered by user. So the compressed air gun cannot be fired when the pressure is low. When the eject chamber is fully refilled and the pressure will push the air refill lock to releases the trigger and while user triggered the trigger, the compressed air gun is fired. That is the semi-auto mode. If the user keep holding the trigger, air refill lock will automatically trigger the piston for firing when the eject chamber is fully refilled. That is the full-auto mode.

Apparatus for acquiring data for configuring a pneumatic air gun comprises a data storage device and a controller. The controller is configured to determine a required velocity for a firing and determine a pressure of an air reservoir, or a pressure in an air flow path at a position downstream of the air reservoir of the gun. The controller is configured to determine a value of a valve activating parameter for the firing and determine a measured velocity of a projectile fired from the gun using the determined value of the valve activating parameter. The controller is configured to determine whether a difference between the measured velocity and the required velocity is within a required limit. The controller is configured to store the determined pressure and the determined value of the valve activating parameter in the data storage device as mapping data for configuring a future firing of the gun when the difference between the measured velocity and the required velocity is within the required limit.

A projectile component that can be removably attached to a flying vehicle is disclosed. The projectile component includes a net configured in the projectile component, a receiving cavity configured in the projectile component, and a weight attached to the net via a string. The weight can be configured in the receiving cavity in preparation for firing the net from the projectile component. In order to entangle a target flying vehicle in the net, a cocklebur associated with the weight is included. Upon firing the net from the projectile component, and upon the net engaging with a target device, the cocklebur becomes entangled with the net to secure the target flying vehicle. A drawstring structure associated with the net can also be used to ensure that the net envelops and captures the target flying vehicle.
