Below is a brief overview of what happens during the Ego LV1
firing cycle. The location of parts discussed in the text below can
be found on pages 70-71.
Assuming the Ego LV1 is gassed up and turned on, FIGURE 29A
shows the marker in its idle position. The rammer is held in its
rear position with pressurised gas from the LPR directed through
the solenoid to the front of the rammer. The valve chamber is
full of pressurised gas from the inline regulator.
Providing a ball is in the breech, when the trigger is pulled, a
signal is sent to the solenoid which redirects the supply of gas
from the front of the rammer to the rear, which pushes the
rammer and bolt forward toward the valve lever (FIGURE 29B) .
As this happens the gas in front of the rammer is vented out
through an exhaust port in the solenoid valve.
The rammer makes contact with the valve lever and continues to
be pushed forward, now pushing the exhaust valve forward with
it. This opens the exhaust valve allowing pressurised gas to flow
up through the valve guide and into the bolt and vent down the
barrel, propelling the ball (SEE FIGURE 29C) .
The time that the rammer is held in this forward position is
dependant on the dwell p arameter. The longer this dwell time
the longer the Ego LV1 vents gas down the barrel. When this
dwell time has elapsed, the solenoid redirects the supply of gas
from the back of the rammer to the front, pushing the rammer
and bolt back to the rear position. This loss of forward force
allows the exhaust valve to re-seal and the valve chamber is
re-pressurised. The valve lever is pushed back into position by
the exhaust valve closing. As the rammer moves back, the gas
behind it is vented through an exhaust port in the solenoid valve
(SEE FIGURE 29D) .
The Ego LV1 has now completed a full cycle.
