Abstract
Es soll eine Einspritzdüse mit einem Piezo-Aktor geschaffen werden, die bei einfachem Aufbau kurze Schaltzeiten und damit geringe Einspritzmengen ermöglicht. Zu diesem Zweck ist eine Einspritzdüse mit einem Düsenkörper (10) vorgesehen, einer in diesem verschiebbaren Düsennadel (12), einem Steuerraum (18), in den die Düsennadel mit einem Ende hineinragt und der über einen Fluidzulauf (20) mit unter Druck stehendem Fluid versorgt wird, und einem Steuerventil (28, 30, 34), das ein Ventilelement (30) aufweist, das einen Fluidablauf (26) aus dem Steuerraum (18) öffnen und schliessen kann, sowie einen Piezo-Aktor (34), der das Ventilelement (30) betätigen kann.
