Abstract
A fluid-flow control device particularly useful as a drip-irrigation emitter, includes a housing having first and second housing sections attachable to each other to define an internal chamber. The first housing section includes an inlet opening at one side of the chamber, and the second housing section includes a hollow stem projecting into the chamber from the opposite side of the chamber and defining an outlet opening from the chamber. A control ring is located within the chamber around the hollow stem and is freely movable, as guided by the hollow stem, towards and away from the inlet opening to control the flow therethrough into the chamber, and thereby the flow through the outlet opening from the chamber.
