Abstract
In order to largely prevent formation of mist in a nozzle head which is attached to a high-pressure paint spray gun, a small spigot from which the paint issues has a very small thickness of less than 0.5 mm. A circular air jet nozzle which surrounds the spigot and beyond whose outlet area the spigot projects, is provided with a depression which fans out the circular air jet. The circular air jet nozzle is surrounded by a rim of air bores which open to the same annulus as the circular air jet nozzle and which have a smaller total cross-sectional area than the area of the circular air jet nozzle and which produce a rotary air umbrella encircling the circular air jet.
