ABSTRACT:
An irrigation emitter including a housing forming a chamber having diverging inlet and outlet walls, the diverging walls forming an apex which receives an end of an emitter plate therebetween; the emitter plate, when subject to pressure at the inlet wall below a predetermined low pressure occupying a position closing the inlet; the emitter plate, when subject to greater low pressure, forming momentarily with the outlet wall a flush flow outlet passage; the confronting surfaces of the outlet wall and emitter plate defining therebetween a drip flow passage. The emitter plate may be circular or rectangular and the portion of the chamber between the emitter plate and outlet wall may be enlarged to effect pressure reducing turbulent flow prior to discharge.
