ABSTRACT:
An irrigation emitter including a fixed longitudinally extending passage wall element having a longitudinally extending restricted flow groove therein, and a flexible longitudinally extending passage wall element overlying the fixed wall element and contacting the fixed wall element along its side margins to define therewith a flush passage and adapted to collapse against the fixed wall element to confine flow to the restricted flow groove. One embodiment of the irrigation emitter having a single fixed wall element and flexible wall element forming a single flush passage and restricted flow groove. Another embodiment includes a ring of fixed wall elements and flexible wall elements forming a ring of flush passages and restricted flow grooves which may be modified for axial discharge or deflected discharge, and the grooves arranged for drip flow, or spray flow; and when arranged for spray flow, may be deflected to produce a segmental spray of selected circumferential extent.
