Cone or turbulence nozzles are so called because they generate a jet of conical form; they are characterized by the presence of a conveyor (formed from one or more oblique channels which emerge into the turbulence chamber, generating a rotary movement on the liquid before the exit) and a plate with a gauged hole of circular form. There is an empty space between these two elements known as the "turbulence chamber" of cylindrical or conical form.
