Abstract: A spray nozzle which is non-plugging and selfcleaning. The nozzle has a central main conduit with an externally mounted water discharge assembly encircling it at its front opened end. A mixture of air and a sealant is forced through the main conduit until it is expelled from the conduit's inwardly tapered front opened discharge end. The water discharge assembly, in the preferred embodiment, has two spaced concentric rings joined together. The rearmost ring serves to mount the assembly to the main conduit and to support a second ring having an internal hollow water conduit section. Near the discharge front end, the front ring is attached to the rear ring by several supporting mounts. The front or outer ring has a plurality of water discharge jets or openings which encircle the front of the main conduit and are fed through their internal hollow section by a water conduit. A tapered surface of the outer ring which faces towards the main conduit cooperates with the gradually tapered outer surface of the main conduit to form an air passage therebetween which encircles the discharge end. As the air-sealant mixture is forced through the main conduit, an air flow is induced in the air passage by the air flow in the main conduit. This induced air flow is between the main conduit and the front ring. This induced air flow serves to remove externally mixed material from the nozzle before the same falls on the water jets.

Abstract translation: 一种不堵塞和自清洁的喷嘴。 喷嘴具有中央主导管，其外部安装的排水组件在其前开口端处环绕。 空气和密封剂的混合物被迫通过主管道，直到其从导管的向内锥形的前开放排放端排出。 在优选实施例中，排水组件具有连接在一起的两个间隔开的同心环。 最后面的环用于将组件安装到主导管并且支撑具有内部中空水导管部分的第二环。 在排出前端附近，前环通过几个支撑座附接到后环。 前环或外环具有多个排水口或开口，其环绕主管道的前部并且通过其导管通过其内部中空部分供给。 外环的面向主管道的锥形表面与主管道的逐渐变细的外表面配合，以形成围绕排出端的空气通道。 当空气密封剂混合物被迫通过主管道时，通过主管道中的气流在空气通道中引起空气流。 这种引起的空气流在主导管和前环之间。 这种诱导的气流用于在喷嘴之前从喷嘴除去外部混合的材料。
