Patent ID: 7988076

Claim:
A non-clogging non-pressure compensated drip emitter comprising: a hollow cylindrical emitter body having an inner cylindrical surface, an outer cylindrical surface, a first end and a second end; a filter; a pool coupled with the outer cylindrical surface wherein the pool is configured to hold water filtered by the filter when the hollow cylindrical emitter body is enclosed in a pipe; and, a labyrinth that defines a water flow path through said drip emitter wherein said labyrinth is coupled with the outer cylindrical surface of said hollow cylindrical emitter body and wherein the labyrinth comprises only turbulent transfer zones once water enters the labyrinth and wherein the labyrinth allows the water to flow from the filter to the pool and wherein said labyrinth starts at said filter and ends at said pool wherein said labyrinth comprises teeth that each have a furthest projection that projects perpendicularly a first distance approximately halfway across said water flow path from a first sidewall of said labyrinth to an opposing sidewall of said labyrinth and wherein said furthest projection of each tooth of said teeth is located along said water flow path at a second distance to at least one other furthest projection of another tooth and wherein said first distance is approximately equal to said second distance.
