Abstract
A fan jet nozzle for surface coating, particularly for high-pressure spraying, is created whose inside dome is not fashioned rotationally-symmetrical. The dome interior is semicircular in the one plane of section in which the nozzle slot extends, but is ogive in the plane perpendicular thereto, the plane which is perpendicular to the lengthwise plane of the fan jet nozzle slot. The two sections, semicircular and ogive, steadily verge into one another around the center axis of the nozzle. The dome configuration results in less wear from abrasion of spraying fluid through the nozzle slot, in particular, onto the wall edge between the dome and the nozzle slot.
