ABSTRACT:
In a spray gun for fluids, such as paint, pressurized air is brought from a hollow handle to a hollow barrel containing an air transition nozzle while the fluid is brought radially into a fluid nozzle in the barrel. The fluid is expelled through a port in the center of the fluid nozzle at the end of the barrel and the pressurized air is expelled out the end of the barrel through openings in an air cap to shape the fluid spray. A cylindrical cartridge, which includes the fluid nozzle and a restricter plug, is movable along the inside of the barrel to change the size and/or shape of the spray and at the same time, control the amount of air to the air cap and the amount of expelled fluid to keep the air-to-fluid ratio substantially unchanged and the air transition nozzle produces a well-defined spray pattern with uniform droplets.
