Abstract
Das Einspritzventil weist einen Ventilkörper (l,2,3) auf,
der in seinem Innern eine Ventilnadel (9) und in seiner
Wand einen Brennstoffzufuhrkanal (l4,l6) sowie auf zwei
verschiedenen Höhen Spritzlöcher (7,8) enthält. Die Ventil
nadel (9) weist einen vom Brennzufuhrstoffkanal (l4,l6)
ausgehenden, sich durch die Ventilnadel erstreckenden und
in deren brennraumseitige Stirnfläche zwischen die beiden
Spritzlöcher (7,8) mündenden Kanal (l8,l9,20) auf. Inner
halb der Wand des Ventilkörpers (l,2,3) ist eine mit dem
Brennstoffzufuhrkanal (l4,l6) kommunizierende, zur Ventil
nadel (9) koaxiale Ringnut (l5) vorgesehen, die sich etwa
über die dem Brennraum (6) abgewendete Hälfte der axialen
Länge der Ventilnadel erstreckt. Das im Ventilkörper (l,2,
3) höher gelegene Spritzloch (8) zweigt im zylindrischen
Abschnitt der die Ventilnadel (9) führenden Bohrung (l0)
im Ventilkörper ab. Zwischen dieser Abzweigstelle und dem
mit der Ventilnadel (9) zusammenwirkenden Ventilsitz be
steht ein axialer Abstand (d).
Durch diese Konstruktion wird es möglich, mit nur einer
Ventilnadel den einzuspritzenden Brennstoff entweder nur
den auf einer Höhe befindlichen Spritzlöchern oder den auf
beiden Höhen befindlichen Spritzlöchern zuzuführen.
