ABSTRACT:
A spray gun pressurized air control system includes an air adjusting knob, a trigger, a trigger seat within a housing, and a control ring. The air adjusting knob comprises a knob at one end having indicia marked thereon, and a hollow shank at the other end to receive a spring therein. An inner end of the spring engages with one end of an enlarged portion of a pin. The other end of the enlarged portion engages with the bottom portion of an L-shaped plate extending downward from one end of the trigger. By adjusting the knob to a predetermined position, pressurized air may be released from a valve controlled by the trigger.
