Abstract

Strahlpistole mit integrierten manuell zu betätigenden Steuerblock, der einerseits die Komponentenzufuhr zu der Strahlpistole regelt, andererseits auf ein Umschaltventil einwirkt, um mittels dieses Umschaltventils entweder in dessen einen Endstellung die Flüssigkeit in eine in die Auslaßdüse für Strahlgut, Gas und Flüssigkeit integrierte Mischkammer gelangen zu lassen, worin deren Zumischung zum Granulat-Gasgemisch und die Aufbereitung als Arbeitsstrahl aus Gas, Flüssigkeit und Granulat in der Weise erfolgt, daß die Zumischung der Flüssigkeit zum Granulat-Gasgemisch tangential zur Strömungsrichtung des Granulat-Gasgemisches erfolgt, sodaß der Arbeitsstrahl beim Austritt aus der Düse sowohl eine axiale Strömungskomponente als auch eine Rotationskomponente um seine Strömungslängsachse hat, oder mittels des Umschaltventiles in dessen anderen Endstellung die Flüssigkeit direkt in eine Flüssigkeitsstrahldüse gelangen zu lassen, mittels der der Flüssigkeitsstrahl ohne Gas- und Granulatkomponente zum Einsatz kommt.
