    • 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.
    • 产生用于表面涂层的风扇喷嘴,特别是用于高压喷涂,其内部圆顶不是旋转对称的。 圆顶内部在喷嘴槽延伸的一个平面中是半圆形的,但是在与其垂直的平面中垂直于与风扇喷嘴狭槽的纵向平面垂直的平面。 半圆形和ogive的两个部分围绕喷嘴的中心轴稳定地彼此相邻。 圆顶结构导致较少的喷涂流体穿过喷嘴槽的磨损,特别是在圆顶和喷嘴槽之间的壁边缘上的磨损。
