摘要： A method of forming an atomizing spray nozzle includes the steps of etching a swirl chamber and a spray orifice in a thin sheet of material. The swirl chamber is etched in a first side of the disk and the spray orifice is etched through a second side to the center of the swirl chamber. Feed slots are etched in the first side of the disk extending non-radially to the swirl chamber such that liquid can be conveyed to the swirl chamber so as to create and sustain the swirling motion. A inlet piece with inlet passage therein is connected with first side of the disk so as to convey liquid to the feed slots of the disk and to enclose the feed slots and swirl chamber. In addition to the method described an atomizing spray nozzle having the configuration described is much improved in its spray characteristics. The present invention also provides a method of forming a number of spray nozzles simultaneously in a single manufacturing process.

摘要翻译： 形成雾化喷嘴的方法包括以薄片材料蚀刻涡流室和喷射孔的步骤。 旋转室在盘的第一侧被蚀刻，并且喷孔通过第二侧蚀刻到涡流室的中心。 进料槽在盘的第一侧被蚀刻，其非径向延伸到涡流室，使得液体可被输送到涡流室，从而产生和维持旋转运动。 其中具有入口通道的入口件与盘的第一侧连接，以将液体输送到盘的进料槽并且包围进料槽和涡流室。 除了所述方法之外，具有所述结构的雾化喷嘴在其喷雾特性方面得到了很大改进。 本发明还提供了在单个制造过程中同时形成多个喷嘴的方法。
