Abstract

Es wird ein Elektromagnet zur Betätigung eines Wegeventils (11) vorgeschlagen, bei dem der Steuerschieber (35) von einem Doppelhubmagneten (10) in wenigstens drei Schaltstellungen verstellbar ist. In einer beiden Spulen (26, 27) des Doppelhubmagneten (10) gemeinsam zugeordneten Flußleitscheibe (28) ist außerhalb eines Druckrohrs (13) ein den Magnetfluß beider Kreise messendes Sensorelement (34) angeordnet, um davon abhängig die Erregerströme beider Spulen (26, 27) zu steuern und dadurch Anzugskräfte und Ankerstellungen zu beeinflussen. Ein 3-Stellungs-Wegeventil kommt mit einem einzigen Sensorelement (34) aus, was eine kostengünstige, kompakte und einfache Bauweise ermöglicht.
