www.duesen-schlick.deSchlick mix nozzlesInjectors• Two media (e.g. two liquids or liquid and gas/steam) aremixed together in injector nozzles in that one mediumacts as the drive medium and the second medium (as inthe venturi principle) is drawn into the mix chamber.• Both media leave the injector as a mixture.Pressure-mix nozzles• Pressure-mix nozzles are available as internal and externalmix nozzles.Principle of internal mix• In internal mix nozzles, both media are mixed in achamber. The mix leaves the orifice as a hollow cone.Principle of Model 770 internal mixMedium IMedium IIMedium l entersthe swirl chamberand decays intodropletsMix of medium land medium ll inthe swirl chamberDischarge ofmedium l andmedium ll dropletsfrom the orificePrinciple of external mix• In external mix nozzles, the two media first meet at theorifice discharge. Mixing takes place when the two hollowcones spray into each other.Principle of Model 772 external mixMedium IMedium IIMix of medium land medium llafter dischargefrom the orifice2
