Abstract: A clog resistant in-line irrigation emitter or nozzle assembly having an emitter structure designed to be inserted into an extruded tube as part of a drip irrigation system. The nozzle assemblies take the high pressure and flow inside the tube and produce a desired flowrate (selectable depending on the requirements of the environment). The emitter of the present disclosure has a higher efficiency than traditional pivot or sprinkler systems or known emitter devices. The emitters not only provide the appropriate pressure attenuation; they resist clogging from the grit and debris in available ground water. The clog resistant in-line irrigation emitter gives a greater pressure attenuation for its physical dimensions than comparable devices and provides an optimal design of a pressure compensating device that improves diaphragm performance. The instant disclosure does allow for the pressure compensation device to be used with various embodiments of a pressure reducing components.

Abstract: A clog resistant online vortex emitter assembly and method uses a double-sided circuit and a series of vortex chambers of optimized dimensions to create a pressure drop with large dimensions and good clog resistance. The vortex emitter allows for pressure regulation without moving parts and includes a unitary body having a first surface and a second surface opposite the first surface and a multi-lumen flow channel providing fluid communication between the first surface and the second surface, wherein said unitary body is a double-sided circuit with a plurality of vortex chambers with lumens aligned in series. The vortex chamber includes an inlet region, a power nozzle, an interaction region and a throat, the inlet region is in fluid communication with the interaction region through the power nozzle. The plurality of vortex chambers includes dimensions to create a pressure drop and be attached to an outer surface of an irrigation tube.
