Abstract

A drip irrigation emitter comprising: a housing (5) including an inlet (63) connectible to a source (2) of pressurized water, an outlet (54) for discharging the water from the housing, and a flow-reducer passageway (52) between said inlet and outlet for reducing the flow of water discharged through the outlet; said flow-reducer passageway including a labyrinth flow path (74) communicating with said inlet, and an outlet control chamber (76) between said labyrinth flow path and said outlet; and an elastomeric member (7) fixed within the housing and defining, with an internal surface thereof, a deformable wall (72) of at least said outlet control chamber, which outlet control chamber is automatically enlarged or restricted by deformation of the elastomeric member in response to flow through said outlet control chamber; said elastomeric member being embossed with an integrally formed relief formation (6) on the surface thereof facing said internal surface of the housing to space same from said internal surface and to permit the enlargement or reduction of said outlet control chamber upon the deformation of the elastomeric member in response to said flow; said relief formation integrally formed in said embossed elastomeric member including a plurality of ribs (73) engageable with said internal surface of the housing and defining therewith said labyrinth flow path; said elastomeric member being formed with said plurality of ribs at one portion (71) thereof defining said labyrinth flow path with the internal surface of the housing, with said deformable wall at the opposite portion thereof, and with a juncture (75) of reduced thickness between said one and opposite portions thereof to increase the deformability of said deformable wall.
