Abstract

Die Erfindung betrifft ein Magnetventil zur Steuerung eines Einspritzventils einer Brennkraftmaschine, welches einen Elektromagneten (29), einen beweglichen Anker mit einer Ankerplatte (28) und einem in einer Öffnung (40) eines ortsfesten Gleitstücks (34) gleitverschiebbar gelagerten Ankerbolzen (27), ein mit dem Anker bewegtes und mit einem Ventilsitz (24) zusammenwirkendes Steuerventilglied (25) zum Öffnen und Schließen eines Kraftstoffdurchgangs (17) und eine an dem von dem Elektromagneten (29) abgewandten Ende des Ankerbolzens (27) ausgebildete Schulter (33) umfaßt, die bei geöffnetem Magnetventil den Öffnungshub des Ankerbolzens (25) durch Anschlag an eine dem Ventilsitz (24) zugewandte Anschlagfläche (37) des Gleitstücks (35) begrenzt. Zur Erleichterung der Montage des Magnetventils wird vorgeschlagen, ein einteiliges oder mehrteiliges Zwischenstück an dem Ankerbolzen anzuordnen, so daß die an dem Ankerbolzen (27) ausgebildete Schulter (33) unter Zwischenlage des Zwischenstücks (50) an der Anschlagfläche (37) des Gleitstücks (35) zur Anlage gelangt.
