Abstract

Die Erfindung betrifft ein Einspritzventil, mit einem Servoventil (12) zur Steuerung der Kraftstoffeinspritzung und mit einem Steuerraum (4), der über eine Zulaufdrossel (2) mit einem Kraftstoffzulauf in Verbindung steht und der über eine Ablaufdrossel (11) mit einem drucklosen Kraftstoff-Rücklauf (13) in Verbindung bringbar. Um ein Einspritzventil bereitzustellen, daß eine gleichmäßige Kleinstmengeneinspritzung gewährleistet, wird erfindungsgemäß vorgeschlagen ,daß die Öffnungs- bzw. Schließgeschwindigkeit über das Verhältnis von Zulauf- (16) und Ablaufdurchmesser (17) der Drosseln (2, 11) einstellbar ist.
