Abstract

Ein Brennstoffeinspritzventil (1) für Brennstoffeinspritzanlagen von Brennkraftmaschinen umfaßt eine Magnetspule (10), einen durch die Magnetspule (10) in eine Hubrichtung gegen eine Rückstellfeder (23) beaufschlagbaren Anker (20) und eine mit einem Ventilschließkörper (4) in Verbindung stehende Ventilnadel (3), wobei der Anker (20) zwischen einem mit der Ventilnadel (3) verbundenen, die Bewegung des Ankers (20) in der Hubrichtung begrenzenden ersten Flansch (21) und einem mit der Ventilnadel (3) verbundenen, die Bewegung des Ankers (20) entgegen der Hubrichtung begrenzenden zweiten Flansch (34) beweglich ist. Zwischen dem Anker (20) und dem zweiten Flansch (34) ist eine Feder (33) vorgesehen, durch welche der Anker (20) in einem Ruhezustand des Brennstoffeinspritzventils (1) so beaufschlagt ist, daß er von einer Anschlagfläche des zweiten Flansches (34) unter Bildung eines Ankerfreiwegs (38) beabstandet ist. Die Feder (33) befindet sich dabei außerhalb des Ankerfreiwegs (38).
