Abrégé

Improvements in a more efficient use of air in a projectile launcher is disclosed. The launcher uses a two-stage air gun fire and reset to have a more efficient compressed gas usage because the gas is not wasted by performing simultaneous actions, instead, the motion dedicates a portion of the motion to firing only then transitions a “port” to close and redirect the gasses to “re-cocking” without wasted gasses going out the firing bolt. The air is redirected through a moving port or gate to allow the launcher to continue to perform and “cycle” to the point where there is low pressure in the supply tank. This prevents chopping or shredding of paintballs because the feed port of the projectiles only partially opens. The improvement allows the launcher to reliably feed and fire projectiles down to the point where it is obvious that the tank requires changing.

An externally adjustable pressure regulator includes a body having a shoulder, a longitudinal axis and a high pressure inlet. The body has an opening along a side. A bonnet has a regulated pressure outlet and is engaged with the body. A piston is positioned in part in the body and the bonnet. The piston has a shoulder, a longitudinal bore and a transverse bore at about the end thereof in flow communication with the longitudinal bore. A spring is disposed on the piston. A wedging element is positioned in the opening in the body side and is in contact with the spring. An adjusting ring engages the wedging element to move it into the spring to increase compression of the spring and off of the spring to decrease compression. Increasing compression of the spring increases a spring force of the spring on the piston and decreasing compression of the spring decreases the spring force on the piston.

A fill station permits transferring a gas, such as a compressed gas from a second device to a first device. The fill station includes a body having an inlet, an inlet/outlet port and an outlet. The body has a passage extending between the inlet, the inlet/outlet port and the outlet. The passage includes a central passage portion. The body includes a bore therein in communication with the central passage portion. A valve assembly includes a seal, a seat, a ball and a biasing member mounted in the body at a first side of the central passage in communication with the inlet/outlet port and a seal, a seal support, and an actuator shaft positioned in the body on an opposite side of the central passage portion. Engagement of the actuator shaft with the ball moves the ball off of the seat to open flow communication from the inlet/outlet port to the outlet and disengagement of the actuator shaft from the ball moves the ball onto the seat to close flow communication from the inlet to the outlet. When the ball is on the seat to close flow communication from the inlet/outlet port to the outlet, flow is communicated from the inlet to the inlet/outlet port.

Improvements in an airsoft kit to convert an airsoft gun to fire paintballs is disclosed. The airsoft kit to convert an airsoft gun to fire paintballs to fire paintballs. The firing of paintballs can be with firing individual paintballs, a burst of about three paintballs successive paintballs rapid fire as paintballs are sprayed in a general area of an opponent. The kit converts an airsoft gun to fire paintballs to handle feeding either airsoft projectiles or paintball projectiles depending upon the installed kit. The kit allows for a user to purchase a single reliable gun that can be used for either activity and then install or remove a fit that allows the gun to be used in either of the two activities. The conversion requires little or no tools and can be performed in the field as the user prepares for their next combat.
