b) Gun or Nozzle. The gun or nozzle is a relatively
complex device (Figure 11). It consists basically of 10 parts:
(1) Air nozzle or cap that directs the compressed
air into the stream of paint to atomize it and carry it to the
surface.
(2) Fluid nozzle that regulates the amount of
paint released and directs it into the stream of compressed air.
(3) Fluid needle that controls the flow of fluid
through the nozzle.
(4)
Trigger that operates the air valve and fluid
needle.
(5) Fluid adjustment screw that controls the fluid
needle and adjusts the volume of paint that reaches the fluid
tip.
(6)
Air valve that controls the rate of airflow
through the gun.
(7) Side port control that regulates the supply of
air to the air nozzle and determines the size and shape of the
spray pattern.
