Abstract

Um die Stabilität eines Magnetkerns (29) eines Elektromagneten für ein Magnetventil (30) zur Steuerung eines Einspritzventils (1) für Brennkraftmaschinen, umfassend einen Magnetkern (29) aus einem Kunststoff-Metallpulvergemisch mit einer axialen Durchgangsöffnung (54) und einer in einer Ausnehmung (74) des Magnetkerns angeordneten Spule (53), bei thermischen und mechanischen Belastungen in axialer Richtung zu erhöhen und eine Aufweitung des Spalts zwischen Anker und Magnetkern im Magnetventil zu vermeiden, wird vorgeschlagen, den Elektromagneten mit einem metallischen Stützgerüst (60,61) zu versehen, das mit dem Kunststoff-Metallpulvergemisch des Magnetkerns (29) ein integriertes Verbundteil bildet und sich durchgehend in axialer Richtung von einer ersten Seite (68) des Magnetkerns (29) bis zu einer von der ersten Seite abgewandten zweiten Seite (69) des Magnetkerns erstreckt.

To ensure the stability of a magnetic core (29) of an electromagnet for a magnetic valve (30) for controlling an injection valve (1) for internal combustion engines, comprising a magnetic core (29) made of a plastic-metal powder mixture with an axial through opening (54) and one in a recess ( 74) of the magnetic core arranged coil (53) to increase thermal and mechanical loads in the axial direction and to avoid widening of the gap between armature and magnetic core in the solenoid valve, it is proposed to provide the electromagnet with a metal support structure (60, 61) which forms an integrated composite part with the plastic-metal powder mixture of the magnetic core (29) and extends continuously in the axial direction from a first side (68) of the magnetic core (29) to a second side (69) of the magnetic core facing away from the first side ,
