Abstract: An improved reversible airless spray tip inhibits dripping, spitting, and undesirable paint accumulation on the spray guard, while improving safety. A positioning detent on the spray tip carrier handle snaps positively into place when a nozzle carrier is rotated into spray position, indicating that the tip is properly positioned for spraying. A spray guard with airfoil-like cross-members protects the user from injury while they inhibit turbulence and prevent paint accumulation. An improved piston seal has a slot-like fluid passage, which is preferably substantially rectangular in cross section. A rearward end of the piston seal is sealed by a resilient ring compressed directly against the face of an attached spray gun. An improved tip retainer is expanded by swaging after insertion, which forces a lip into a mating slot. The tip retainer also has an expanded chamber which diffuses reverse fluid flow for safety.

Abstract translation: 改进的可逆无气喷雾头防止喷雾器上的滴水，吐痰和不期望的油漆积聚，同时提高安全性。 当喷嘴托架旋转到喷射位置时，喷嘴托架手柄上的定位棘爪可以正确地卡入到位，指示尖端正确定位以进行喷涂。 具有翼型横档的防喷器保护使用者免受伤害，同时抑制湍流并防止油漆积聚。 改进的活塞密封件具有槽状流体通道，其优选地基本上是矩形的横截面。 活塞密封件的后端由直接压靠附接的喷枪的表面的弹性环密封。 改进的尖端保持器在插入后通过模锻而膨胀，这迫使唇缘进入配合槽。 尖端保持器还具有扩大的腔室，以便安全地扩散反向流体流动。
