Abstract
An emitter for receiving water from a trickle irrigation system and emitting the received water at a trickle flow rate to an area to be irrigated. The emitter includes a float controlled water inlet shutoff valve for receiving water from the trickle irrigation system and supplying it to a housing to establish a water supply therein and maintain the water supply at a predetermined substantially constant level above at least one water outlet opening of predetermined size formed in the housing to provide a pressure head which interacts with the size of the water outlet opening to determine the trickle output flow rate of the emitter.
