Editing Smart Parts Ion (section)

== Operating system ==

The Ion uses an open-bolt electropneumatic spool-valve mechanism.

Its firing assembly incorporates a moving bolt, firing chamber and pneumatic control system.

When the marker is ready to fire, pressure controlled by the solenoid holds the bolt in its rearward position.

Pulling the trigger activates the electronic firing system, which changes the pressure acting on the bolt.

The bolt moves forwards, chambering the paintball and opening passages that release compressed air through the barrel.

After firing, the solenoid restores the pneumatic pressure required to return the bolt to its original position.[4]

The marker's standard electronic components include:

* Electronic trigger and control board.
* Purpose-designed solenoid.
* Beam-break Vision anti-chop eye system.
* Programmable firing modes.
* Nine-volt battery.
* Electronic tournament-lock provision.

The original Ion's operating pressure was approximately 140–200 psi, depending on its configuration and adjustment.[3][4]
