Abstract
A drip irrigation emitter includes a disc shaped body having a pressure reducing labyrinth between a water inlet area and an outlet hole, and a pressure regulating diaphragm changing flow through the outlet hole in response to water pressure fluctuations in the water conduit where the emitter is mounted. The water filtering inlet of the emitter is located entirely at the sides of the disc shaped body.
