Abstract

Die Einspritzvorrichtung zum Einspritzen von unter Hochdruck stehendem Brennstoff in dem Brennraum einer Verbrennungskraftmaschine weist ein Einspritzventil auf, welchem eine diskrete Speicherkammer (68) zugeordnet ist. Zwischen dieser und der Hochdruckzuleitung (44) wirkt ein Rückschlagventil (74), wobei der vorzugsweise als Stabfilter (72') ausgebildete Filter (72) einen Anschlag (106) zur Begrenzung der Öffnungsbewegung des vorzugsweise als Ventilgliedblättchen (100' ) ausgebildeten Ventilglieds (100) bildet.
