of the main components
(for illustrati on only)
When the valve is not acti vated, the
needle closes the nozzle seat, pushed
by a spring, and stops the fl uid under
pressure to fl ow out from the nozzle
hole.
When the external solenoid valve
that allow the drive air to fl ow inside
the piston chamber is acti vated, this
acti on acti vated the valve. Then the
piston moves back together with
the needle, allowing the fl uid fl ow
to come out from the nozzle. At the
same ti me, the acti vati on of the
second external solenoid valve allows
the nebulizati on air to fl ow inside the
air cap where it mixes with the fl uid
and comes out from the air cap in
spray form.
