Class Information
Number: 239/461
Name: Fluid sprinkling, spraying, and diffusing > Flow deflecting or rotation controlling means
Description: Apparatus comprising means for (1) imparting a swirling or spinning (rotary or spiraling) motion to a flowing fluid in a fluid conductor prior to egress thereof, (2) smoothing out or quieting a turbulent or rotating flowing stream in a fluid conductor, or (3) redirecting and dispersing a flowing stream by some surface means positioned beyond the egress port or last point of fluid confinement and in a direct line therewith to accomplish an abrupt change in the direction of flow of the fluid.
