ABSTRACT:
A drip irrigation emitter or device comprising a flow restrictor helical thread on the outside of a main body, and a cap member that fits over the thread. Water is supplied to the interior of the main body and must flow through a narrow, annular passageway formed by the cap before the water flows through provided restrictor orifices, so no large particles are carried into the orifices or the helical thread to minimize plugging. The water discharges adjacent to the water tube or hose to minimize root intrusion into the irrigation device, and baffles also are provided to minimize root intrusion. The cap can be loosened or removed to flush the thread if foreign material enters the thread.
