Abstract

A paintball gun includes a frame, an operating assembly at least partially slidably received within the frame and having a locking pin receptacle, and a locking pin within the frame having two positions. In a break down position, the locking pin is received entirely within the frame and the operating assembly can freely slide in or out of the frame. In a firing position, the locking pin extends partially from the frame into the locking pin receptacle within the operating assembly, preventing the operating assembly from coming out of the frame. The paintball gun may include a spring biasing the locking pin in the break down position and a pressurized gas system that transitions the locking pin to the firing position when pressurized gas is introduced.

Abstract

A paintball marker is provided, comprising: a housing; a combustion chamber defined within the housing; a piston movable within the housing; a bolt driven by combustion within the combustion chamber; a fuel system in fluid communication with the combustion chamber; an oxidizing system in fluid communication with the combustion chamber; and an ignition system configured to ignite a mixture of fuel and oxidizing agent in the combustion chamber, wherein combustion of the mixture drives the piston to actuate the bolt.

• F41A 1/04 - Missile propulsion using the combustion of a liquid or gaseous fuel, e.g. hypergolic fuel

Abstract

A fuel powered paint marker having a first stage and a second stage comprising: a housing; a combustion chamber; a piston; a compression chamber; a fuel system; an oxidizing system; an oxidizing agent; a fuel assembly included in the fuel system; a separation assembly included in the fuel system and separating the oxidizing agent from the fuel assembly in the first stage; a bolt drive system; a fuel nozzle included in the fuel system for injecting fuel into the combustion chamber during the second stage; and, an ignition for igniting the fuel and oxidating agent in the combustion chamber driving the piston forward and compressing a gas in the compression chamber thereby ejecting a projectile wherein the fuel and oxidizing agent are separated during the first stage and mixed in the combustion chamber.

Abstract

This system is a pneumatic actuation valve assembly that can include a frame; a timing spool housing; a timing spool carriage; a timing spool; a magnet configured to bias the timing spool in a forward position; a main spool and configured to travel toward a frame forward portion when a fluid is received into a mid-main spool pressure area wherein the main spool actuates a bolt carried by the frame and is configured to receive a projective in an open position and chamber the projective in a closed position; and, a bore defined in the timing spool configured to allow pressure in a rear main spool pressure area to escape through the bore releasing rearward pressure on the timing spool allowing the timing spool to travel from the rearward position to the forward position according to an attraction of the magnet.

Abstract

A gas projectile platform having a trigger that can rotate when pressure is applied to the trigger, a first spool biased against a magnet, a pad assembly that, when actuated, allows pressure to enter an first spool pressure area forward the first spool and configured to release the first spool from the magnet when sufficient pressure is transferred to the first spool pressure area, the first spool configured to transmit pressure to a second spool wherein the second spool is configured to be positioned rearward overcoming a spring force to allow press to release from a bolt pressure area, wherein the bolt pressure area is pressurized when the bolt is in a forward position and configured to transition rearward when the second spool overcomes the spring force and wherein an ejection pressure stored in a bolt pressure area is transmitted to a chamber and ejects a projectile from a barrel.
