Abstract
An irrigation emitter is provided for delivering irrigation water from a water supply conduit, such as an irrigation supply tube, pipe, or other water supply apparatus, at a low volume or drip-like flow rate. The emitter operates generally through the use of a reduced size orifice and a relatively long tortuous flow channel that cause a pressure reduction between the water supply conduit and an emitter outlet. The emitter includes an inlet for tapping a portion of the water flow from the water supply conduit and, when the water pressure is above a predetermined minimum level, directing the flow to and through the flow channel for subsequent discharge to a desired location. The emitter also may regulate to accommodate for changes in supply pressure. The emitter also may include multiple emitter outlets.
