OPERATIONAL OVERVIEW
Below is a brief overview of what happens when
you fire your Geo3. The location of parts discussed
in the text below can be found on pages 76-77.
Assuming the Geo3 is gassed up and turned on
Figure 6A shows the marker in its idle position.
The firing 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 firing 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 firing 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
(figure
6B)
.
As the bolt passes the front prop shaft o-ring
the firing chamber seal is broken and the air in
the firing chamber vents down the bolt, in turn
propelling a ball
(figure 6C).
As air is vented from the firing chamber the force
pushing the prop shaft back is overcome by the
spring tension in the back cap. The spring pushes
the prop shaft forward. The front 14x2 o-ring on
the prop shaft enters the bolt and seals off the
firing chamber
(figure 6D).
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 firing
chamber is re-filled 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.
