Abstract

Atomizing device for producing a liquid/gas mixture (4) comprises a nozzle body (20) having an at least approximately central pipe (16) for the gaseous medium and a nozzle chamber (18) for the liquid medium which rotationally-symmetrically surrounds the tube. A liquid feed (17) has devices for producing a swirled liquid flow into the nozzle chamber. The liquid leaves the nozzle body through a nozzle opening (19) coaxially surrounding the pipe. An Independent claim is also included for the production of a liquid/gas mixture using an atomizing device. Preferred Features: The liquid feed opens tangentially into the nozzle chamber. The nozzle chamber narrows to an annular nozzle opening.
