Abstract

Ein Zweistoff-Injektor, insbesondere für Brennkraftmaschinen, weist einen Düsenkörper (2), der einen Düsenaustritt (3) aufweist, eine Ventilnadel (4) zum Öffnen und Schließen des Düsenaustritts (3), einen ersten Zufuhrkanal (7) zur Zufuhr einer ersten Flüssigkeit zu dem Düsenaustritt (3), einen zweiten Zufuhrkanal (10) zur Zufuhr einer zweiten Flüssigkeit zu dem Düsenaustritt (3) und gegebenenfalls einen in dem Düsenkörper (2) sich befindlichen Flüssigkeitsraum (6) auf, der sich an den Düsenaustritt (3) anschließt. Der zweite Zufuhrkanal (7) ist über wenigstens zwei Bohrungen (11) mit dem Flüssigkeitsraum (6) oder dem ersten Zufuhrkanal (7) verbunden. Die wenigstens zwei Bohrungen (11) münden derart in den Flüssigkeitsraum (6) oder den ersten Zufuhrkanal (7), daß die zweite Flüssigkeit in dem Flüssigkeitsraum (6) oder dem ersten Zufuhrkanal (7) eine Drallströmung erzeugt.

Figure 00000001
A two-substance injector, in particular for internal combustion engines, has a nozzle body (2) which has a nozzle outlet (3), a valve needle (4) for opening and closing the nozzle outlet (3), a first feed channel (7) for feeding a first liquid to the nozzle outlet (3), a second feed channel (10) for feeding a second liquid to the nozzle outlet (3) and optionally a liquid space (6) located in the nozzle body (2), which connects to the nozzle outlet (3) , The second feed channel (7) is connected to the liquid space (6) or the first feed channel (7) via at least two bores (11). The at least two bores (11) open into the liquid space (6) or the first feed channel (7) in such a way that the second liquid generates a swirl flow in the liquid space (6) or the first feed channel (7).
