Abstract

Die Erfindung betrifft einen Injektor, insbesondere zur Kraftstoffeinspritzung, mit einem Magnetventil (1) zur Steuerung eines Einspritzventils (2), wobei das Magnetventil (1) einen bewegbaren Anker (3) aufweist, der auf einen Ventilsitz (4) im unteren Ankerraum (5) aufbringbar ist. Der untere Ankerraum (5) steht über Bohrungen (6, 7) mit dem Steuerdruckraum (8) des Einspritzventils (2) in Fluidverbindung. Über eine Rücklaufbohrung (9) können auftretende Leckmengen über den unteren Ankerraum (5) in einen Tank zurückgeführt werden. Um beim Schließen des Ventilsitzes (4) durch den Anker (3) ein Ankerprellen zu verhindern, wird vorgeschlagen, in dem Injektor Mittel zur Reduzierung von im unteren Ankerraum (5) auftretenden Druckschwankungen vorzusehen. Die Beseitigung von Druckschwankungen im unteren Ankerraum (5) führt weitestgehend zu einer Beseitigung des Ankerprellens.
