    • A spray gun includes a main body and a spray head. The spray head has an air cap, a hollow nozzle member having a nozzle tip for dispensing a liquid to be sprayed. The hollow nozzle member has a radially extending weir which together with a surface of the main body defines an air distribution chamber for receiving and distributing compressed air from a supply inlet. An annular sealing member is sealingly disposed between the radially extending weir and the surface of the main body, dividing the chamber, so that air passing into the chamber through an opening to one side of the annular wall is directed to a central aperture of the air cap and air passing into the chamber through an opening to the other side of the annular wall is directed to lateral apertures of the air cap.
    • 喷枪包括主体和喷头。 喷头具有空气帽,中空喷嘴构件具有用于分配喷射液体的喷嘴尖端。 中空喷嘴构件具有径向延伸的堰,其与主体的表面一起限定了用于从供应入口接收和分配压缩空气的空气分配室。 密封地设置在径向延伸的堰和主体的表面之间的环形密封构件,分隔室,使得通过环形壁的一侧的开口进入室的空气被引导到空气的中心孔 通过通向环形壁的另一侧的开口进入腔室的帽和空气被引导到空气帽的侧向孔。
