Abstract

Es wird ein Druckventil (1) vorgeschlagen, das in die Förderleitung (4), die von einer Kraftstoffeinspritzpumpe zu einem Kraftstoffeinspritzventil (3) führt, eingebaut wird und ein Ventilschließglied (20) aufweist, das unter Einwirkung des Förderdruckes im wesentlichen die zur Einspritzung kommende Kraftstoffeinspritzmenge verdrängt. Zusätzlich kann durch im Bypass zum Ventilschließglied (20) vorgese­ hene Drosselquerschnitte Kraftstoff zur Sicherstellung eines Standdruckes in der Kraftstofförderleitung am Ventilschließ­ glied vorbeiströmen. Zum Abbau von Druckwellen im För­ derleitungsteil zwischen Druckventil und Einspritzventil nach Beendigung der Kraftstofförderung wird das Ventilschließ­ glied unter Verdrängung von Kraftstoff durch die Drossel­ querschnitte (20) verzögert in seine Schließstellung zurück­ geführt, wobei zusätzlich der Standdruck durch eine Drossel­ bohrung (28), die von einem Rückschlagventil (30) kontrol­ liert wird, auf einen gewünschten Wert eingestellt werden kann.
