2.  Needle
3.  Piston
4.  Spring
5.  Solenoid valve

When the valve is not activated, the
needle closes the nozzle seat, pushed
by a spring, and stops the fluid under
pressure to flow out from the nozzle
hole.

When  the  solenoid  valve  that  allow
the drive air to flow inside the piston
chamber  is  activated,  this  action
activated  the  valve.  Then  the  piston
moves back together with the needle,
allowing  the  fluid  flow  to  come  out
from the nozzle.
