Abstract: A method of atomization control and related gas atomizing nozzles are described which enable variation of the degree of atomization, the liquid and gas flow rates and the atmospheric spray dilution. Varying the thickness of flowing liquid and adjacent atomizing gas sheets varies spray droplet size and atmospheric spray dilution. Transverse sheet size is varied to change nozzle capacity. Annular and linear sheet forming nozzles are described. Nozzles are also described with flexible divider walls whereby thickness of the flowing sheets may be varied by altering relative flow pressures.

Abstract: A liquid discharge nozzle having no moving parts, includes a hollow body defining a liquid inlet at one end and an outlet opening at the other end. The body has an internal chamber arranged in communication with both the inlet and outlet ends of the body. A plug, having substantial length between opposite end surfaces, is disposed across the chamber inwardly of the bodyoutlet end and grooves in the sidewalls of the plug define constricted liquid-outlet means from the body. An air duct extends through the plug from adjacent the body outlet to the exterior of the body between the plug and inlet end of the body.

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。

Abstract: For an HVLP paint spray gun, an improved suction feed nozzle assembly including a fluid tip and an air cap. The air cap directs an annular flow of atomization air around a fluid discharge orifice formed by a tubular portion on the fluid tip to aspirate fluid from the orifice and to atomize the fluid. The air cap also directs pattern shaping air at the atomized paint. According to one feature of the invention, the spacing of the pattern shaping air orifices from the fluid discharge orifice is made sufficiently great that undue turbulence is not induced in the atomization air in the aspiration zone to maximize the fluid flow rate. According to a second feature of the invention, the fluid orifice in the fluid tip has a straight cylindrical portion and an expanding conical section connecting the cylindrical section to an annular flat front face of the tubular portion of the fluid tip. The flat portion of the front face on the tubular portion is kept to a minimum to increase the particle distribution uniformity of the atomized paint. Preferably, a sharp comer if formed between the flat face and the sides of the cylindrical section to optimize fluid flow at low air pressures.

Abstract: A liquid-atomizing nozzle in which intermixing of air and liquid occurs externally of the nozzle and the primary air utilized for such intermixing is amplified by the entrainment of ambient secondary air. Two versions of the nozzle are disclosed, each having a tubular body with a generally cylindrical section terminating in a conical nose section. Air under pressure is discharged through radial openings in the cylindrical section and is redirected by a collar surrounding the cylindrical section to form a high velocity stream of air about and along the gradually-tapered outer surface of the nose section. Such high velocity primary air, amplified by ambient secondary air, strips liquid from at least one opening in the nose section to produce an externally-developed air-liquid mixture. In one version the liquid discharge opening is at the tip of the conical nose section; in another version a plurality of such openings are formed in the conical surface of that section.
