pulvérisateur à jet conique

OBS: Jet conique : jet dont la forme générale présente l'aspect d'un cône.

CONT: Cone nozzle. Liquid is forced through a swirl plate, having one or more tangential or helical slots or holes, into a swirl chamber. An air core is formed as the liquid passes with a high rotational velocity from the swirl chamber through a circular orifice. The thin sheet of liquid emerging from the orifice forms a hollow cone as it moves away from the orifice, owing to the tangential and axial components of velocity. A solid cone pattern can be achieved by passing liquid centrally through the nozzle to fill the air core: this gives a narrower angle of spray and larger droplets.
