Abstract

Es wird eine Kraftstoffeinspritzvorrichtung für Brennkraftmaschinen vorgeschlagen mit einem Magnetventil (24), das eine Dämpfungskammer (40) und einen Entlastungsraum (41) aufweist, die durch eine sowohl laminar als auch turbulent dämpfende Dämpfungsdrossel (39, 51) hydraulisch in Verbindung stehen. Dadurch wird die Welligkeit der Kennlinien des Kraftstoffeinspritzsystems verringert und dessen Funktion verbessert.
