GEO3.5 MANUAL 67

Below is a brief overview of what happens when you re your GEO3.5. The

location of parts discussed in the text below can be found on pages 68-69.

Assuming the GEO3.5 is gassed up and turned on gure 27A shows the marker

in its idle position. The ring chamber is full of compressed air, the prop shaft is

pushed back into the back cap by this compressed air. The bolt is held back by

the air in the bolt can. Both the ring chamber and the bolt can are supplied with

air via the solenoid valve.

Providing a ball is in the breach when the trigger is pulled, a signal is sent to the

solenoid valve which shuts off the supply of air to the ring chamber and allows

the air in the bolt can to be exhausted. This removes the force holding the bolt in

its rear position and the bolt is propelled forwards (gure 27B).

As the bolt passes the front prop shaft o-ring the ring chamber seal is broken

and the air in the ring chamber vents down the bolt, in turn propelling a ball

(gure 27C).

As air is vented from the ring chamber the force pushing the prop shaft back is

overcome by the spring tension in the back cap. The spring, along with a small

volume of air used to propel the paintball ported to the rear of the propshaft,

pushes the prop shaft forward. The front 14x2 o-ring on the prop shaft seals off

the ring chamber against the inside of the bolt (gure 27D).

The length of time the bolt remains in this forward position is dependant on dwell.

When the solenoid has completed its dwell time, air is routed back into the bolt

can and pushes the bolt back towards its rear position. Simultaneously the ring

chamber is re-lled through the solenoid valve to the operating pressure set by

the user via the inline regulator, and the prop shaft is pushed into its rear position

by the air pressure inside the valve chamber (gure 27E).
