    • A rotary atomizer spray coating device (202), in certain embodiments, has a bell cup (206) with a generally parabolic flow surface (210). This generally parabolic flow surface (210) provides additional surface area for dehydration of coating fluids, thereby improving color matching as compared to traditional bell cups, for example, by affording capability for higher wet solids content. In addition, the coating fluid accelerates along the generally parabolic flow surface, resulting in the fluid leaving the bell cup at a greater velocity than in traditional bell cups. Furthermore, a splash plate (212) disposed adjacent the bell cup, in certain embodiments, is designed such that fluid accelerates through an annular area between the splash plate and the generally parabolic flow surface. This acceleration may substantially reduce or eliminate low-pressure cavities in which fluid and/or particulate matter may be trapped, resulting in an even application of coating fluid and more effective cleaning of the bell cup as compared with traditional bell cups.
    • 在某些实施例中,旋转雾化器喷涂装置(202)具有具有大致抛物面流动表面(210)的钟形杯(206)。 这种通常为抛物面的流动表面(210)为涂层流体的脱水提供了额外的表面积,从而与传统的钟罩相比提高了颜色匹配,例如通过提供更高的湿固体含量的能力。 此外,涂层流体沿着大致抛物线的流动表面加速,导致流体以比传统钟形杯更大的速度离开钟形杯。 此外,在某些实施例中,设置在钟罩附近的飞溅板(212)被设计成使得流体通过防溅板和大致抛物面流动表面之间的环形区域加速。 这种加速可以显着地减少或消除其中流体和/或颗粒物质可能被捕获的低压空腔,导致与传统的钟形杯相比,涂层流体的均匀施加和钟罩的更有效的清洁。
