ABSTRACT:
A spray system is disclosed which includes a spray gun for the hand-operated spraying of fluid material with pressurized air. A spray gun body includes a barrel chamber having an air tube which directs air outwardly through a discharge port with entrained material in a spray. A bistable control valve operates responsive to movement of a trigger for controlling the flow of both air pressure and material into the barrel chamber. The control valve is bistable in its operation to either close the air flow off when the trigger is in its off position or to open the air flow when the trigger is in any of its operating positions. Air tube adjustment means is provided for manually controlling the spray pattern during operation. An electrical control circuit is provided to control a material flow pump responsive to movement of the trigger.
