Abstract
A spray nozzle for pop-up underground sprinkler comprises a main fixed body and a revolving ring nut that is associated with the aforesaid main body in order to allow the adjustment of the spray angle. The main body and the ring nut as a whole create an area for the containment of water that communicates with the outside through an adjustable scroll-shaped radial passage. The ring nut in addition forms in communication with the aforementioned area an accumulation chamber in which the water flow is subject to compression for the formation of a uniform output spray.
