Title: Atomizing nozzle
Inventor: IGARU GIRADO
IPC: B05B1/34
Filed: 1979-10-29
Abstract: A spray or atomizing nozzle for any agricultural, industrial or other purpose, comprises a vortex chamber (8), an outward-flaring outlet orifice (12) and a movable spray-control body (14). The spray-control body, in the non-operative state of the nozzle, rests on the flaring rim of the outlet orifice, while in the operative state the spray-control body, being impacted by the liquid issuing from the outlet orifice, is slightly lifted off the flaring rim of the outlet orifice, facilitates deflection of the impacting liquid outwards and produces a droplet spraying effect. Due to the negative-pressure zone created in the vortex chamber, the spray control body is maintained floating in a position of equilibrium at a close distance from the orifice rim, whereby the droplet-size spectrum of the spray is controlled.
