摘要： A two-material atomizing nozzle to produce a solid cone jet with a jet angle larger than 45.degree. comprises a nozzle unit with a first duct coaxial with the nozzle discharge and receiving a gaseous medium (for instance air) and a liquid medium (for instance water), a second duct orthogonal to the first duct and issuing into it serving to supply the liquid medium. To supply the gaseous medium, the nozzle unit comprises a third duct issuing into the first duct at the level of the second duct and being orthogonal or essentially orthogonal to both. A recoil bottom is provided for the premixed two-material mixture in the first duct and comprises communication apertures to an annular duct coaxial with and preceding the nozzle discharge into which it merges. The nozzle discharge also is in the shape of an annular duct, however its external boundary is flaring. Such a two-material atomizing nozzle is characterized by a large jet angle, by uniform liquid distribution, by large flow cross-sections and by wide freedom from clogging.
