Abstract
A dual-material atomizing nozzle comprises a housing (10) with a gas intake (13), a liquid intake (14) and with a mixing chamber (11) for the gaseous and liquid components; a rod-like insert (16) flaring into a saucer-shape opposite the nozzle exit extends through the mixing chamber (11) along its longitudinal axis (15); the end of the housing (10) which is at the nozzle exit side is thus covered while forming an approximately radial, annular-gap shaped nozzle exit slot (23). At least one convergent/divergent tube-path (28, 29; 25, 24) based on the Laval principle is provided within the mixing chamber (11) no farther than the nozzle exit (12). Thereby, and especially when a second convergent/divergent tube path (25, 24) is present behind the liquid intake (14), first the gas and also the mixture of gas and liquid will be accelerated within the nozzle housing (10) to supersonic speed. In this manner a dual-material atomizing nozzle is created with an adequately large angle of jet and providing fine droplets, being insensitive to soiling and requiring only a slight ratio of gas to liquid, being resistant to wear and clogging.
