Abstract:
A fluid flow emitter to be mounted entirely within a fluid distribution tube comprising:a cylindrical body defining an axially extending inner region aligned with the tube in which the emitter is to be mounted, an outer surface including raised portions defining at least one flow-rate control path, at least some of the raised portions to be positioned against the inner diameter of the tube, with a plurality of holes interconnecting the inner region and the flow-rate control path, wherein the flow-rate control path is disposed between two annular sealing regions that form a fluid-tight seal when the emitter is disposed within an appropriately-sized fluid distribution tube, and wherein the flow-rate control path and the holes combine to cover at least 33 percent of the outer surface of the cylindrical body between the annular sealing regions, the flow-rate control path being hydraulically connected with an orifice in the fluid distribution tube to permit fluid to pass at a controlled rate from the tube, through the holes, along the flow-rate control path and out of the tube.
