<p>An emitter valve (76) having a diaphragm chamber (80) for an irrigation system comprising an irrigating fluid inlet (77) for establishing fluid communication with said diaphragm chamber (80), a diaphragm (87) mounted for translation between first and second positions in a gap within said diaphragm chamber (80) of about 0.16" reduced by the thickness of said diaphragm chamber to a net gap of about 0.125" within the diaphragm chamber to control fluid flow therethrough, said diaphragm being flexible under the pressures of the irrigating fluid but maintaining diaphragm dimension when subjected to the irrigating fluid pressures, a cone (81) spaced from said inlet and separated from said inlet by said diaphragm, an emitter nozzle (88) formed on said cone (81), said emitter nozzle (88) being coterminous with the emitter valve body, and a discharge nozzle (85) in fluid communication with said diaphragm chamber, said discharge nozzle (85) being parallel with said fluid inlet (77). <IMAGE></p> |
