Abstract

Die Erfindung geht aus von einer hydraulischen Steuervorrichtung (60), insbesondere für einen Injektor (16) eines Kraftstoffeinspritzsystems (10) bei Kraftfahrzeugen. Bekannte Steuervorrichtungen weisen einen piezoelektrischen Aktor auf, der ein als A-Ventil ausgebildetes Wegeventil (75) mit einem in einer Ventilbohrung (76) geführten Ventilglied (74) steuert. Erfindungsgemäß wird vorgeschlagen, zwischen den Aktor (52) und das Ventilglied (74) einen die Auslenkbewegung des Aktors (52) umkehrenden Übersetzer (62) zu schalten und das Wegeventil (75) als nach innen öffnendes 3/2-Wegeventil auszuführen. Dessen Ventilglied (74) gibt in Wirkverbindung mit einem Ventilsitz (98) und einer Steuerkante (96) Druckmittelverbindungen zwischen Druckmittelkanälen (86, 88, 92) wechselweise frei oder unterbricht diese.
