Abstract

Vorgeschlagen wird, bei einem Magnetventil zur Steuerung eines Einspritzventils einer Brennkraftmaschine, umfassend einen Elektromagneten (20), einen beweglichen Anker mit Ankerplatte (28) und Ankerbolzen (27) und eine mit dem Anker bewegtes und mit einem Ventilsitz (24) zusammenwirkendes Steuerventilglied (25) zum Öffnen und Schliessen eies Kraftstoffablaufkanals (17) eines Steuerdruckraums 814) des Einspritzventils (1), welche Ankerplatte (28) unter Einwirkung ihrer trägen Masse in Schliessrichtung des Steuerventilgliedes (25) entgegen der Spannkraft einer auf die Ankerplatte (28) einwirkenden Rückholfeder (35) auf dem Ankerbolzen (27) gleitend verschiebbar gelagert ist und in ihrer Ruhelage von der Rückholfeder (35) gegen ein an dem Ankerbolzen (27) angeordnetes Anschlagteil (26) angedrückt wird, das Anschlagteil (26) so auszugestalten, dass es in einer Ebene senkrecht zur Bewegungsrichtung des Ankerbolzens (27) den Ankerbolzens im Umfang um mehr als 180° umschliesst.
