摘要： A tip guard is provided to protect a user of an air-assisted airless paint spray gun from injury. The shape of the tip guard is designed such that use of the tip guard is not detrimental to the fluid spray pattern emitted from the tip of the air-assisted airless paint spray gun. Use of the tip guard does not affect the size or shape of the fluid spray pattern, nor cause accumulation of paint upon the tip guard. The tip guard has a base having a shoulder and an aperture adapted for engagement to the air cap and tip of an air-assisted airless paint spray gun. The base further has a pair of transition portions extending axially forward from said aperture, where notches formed in the transition portions are adapted to engage the forwardly-extending horns of the air cap of an air-assisted airless paint spray gun. Each transition portion further has a pair of vanes extending forwardly and radially outwardly from the transition portion, where each of said pair of vanes is then joined by a crossbar.
摘要翻译： 提供防护罩以保护空气辅助空气喷涂枪的使用者免受伤害。 前端保护罩的形状被设计成使得尖端护罩的使用对于从空气辅助无空气涂料喷枪的尖端发射的流体喷射图案是不利的。 尖端防护罩的使用不会影响流体喷雾图案的尺寸或形状，也不会导致涂料在喷嘴防护罩上的积聚。 前端防护罩具有一个具有一个肩部和一个适于与空气帽和空气辅助空气喷涂喷枪的尖端相接合的孔的底座。 底座还具有从所述孔轴向向前延伸的一对过渡部分，其中形成在过渡部分中的凹口适于与空气辅助无空气涂料喷枪的空气帽的向前延伸的角接合。 每个过渡部分还具有从过渡部分向前和径向向外延伸的一对叶片，其中所述一对叶片中的每一个然后通过横杆连接。

摘要： A nozzle for use in a foam gun is designed so that the ports for the two materials both enter the flow passage in the same plane. This serves to eliminate lead/lag flow conditions which result in portions of the material being off-ratio. Counterbored or milled slots encircle the angled sealing surface with the slots machined in from alternating edges of the surface communicating with the respective flow passages for the two (or more) materials.

摘要： A needle assembly for an airless spray gun is provided with a needle which is centerless ground and electropolished to greatly increase life. Further life enhancements are gained by use of a plastic needle bushing in the needle clamp and provision of a specific length to diameter geometry for the needle yields enhanced life as well.

摘要： A liquid-atomizing spray gun having an improved nozzle construction for spraying liquids under predetermined hydraulic pressures, and with the assistance of carbon dioxide gases, wherein the nozzle includes a forwardly-projecting shield having ports directed toward the atomized spray pattern emanating from a spray tip. The nozzle also includes ports for ejecting CO.sub.2 gas for assisting in the atomization process, the overall design providing CO.sub.2 -assisted hydraulic spraying and preventing air entrainment into the atomized particles in the region proximate the spray nozzle.
