OPERATIONAL OVERVIEW
Below is a brief overview of what happens
when you re your Geo2. The location of parts
discussed in the text below can be found on page
72-73.
Assuming the Geo2 is gassed up and turned on
FIGURE 1.1 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 Can. Both the Firing Chamber and the
Can are supplied with air via the Solenoid Valve.
Providing a ball is in the breach and the Trigger is
pulled, a signal is sent to the Solenoid which stops
the supply of air to the Firing Chamber and allows
the air in the Can to be exhausted. This removes
the force holding the Bolt in its rear position and
the Bolt is propelled forwards FIGURE 1.2.
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 1.3.
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 o the
Firing Chamber FIGURE 1.4.
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 Can and pushes the Bolt
back towards its rear position. Simultaneously the
Firing 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. FIGURE 1.5.
