ABSTRACT:
An emitter device for a drip type irrigation system. The emitter has an elongated body with a tapered portion at its lower end to facilitate easy insertion into the soil. The upper end of the emitter forms a small receiving chamber connectable to an opening. An adjustable valve means is interposed between the chamber and the opening so that the flow of water from a suitable supply source can be regulated. Outlet openings for the emitter are located near or within the tapered portion of the body so that emission is accomplished below ground level.
