Abstract

Elektrischer Ventiltrieb für Verbrennungsmotoren mit einem verschieblich angeordneten Anker, der eine Ankerplatte aufweist, einem ersten Elektromagneten, der auf der einen Seite der Ankerplatte angeordnet ist und einem zweiten Elektromagneten, der auf der anderen Seite der Ankerplatte angeordnet ist. Die Elektromagneten weisen jeweils ein Joch und eine daran angeordnete Spule auf. Durch Bestromen der Spule des einen Elektromagneten ist ein Magnetfeld erzeugbar, das den Anker in Richtung einer ersten Endstellung zieht und durch Bestromen des anderen Elektromagneten ist ein Magnetfeld erzeugbar ist, das den Anker in entgegengesetzte Richtung zu einer zweiten Endstellung zieht. An mindestens einem der Joche ist mindestens ein Permanentmagnet angeordnet, welcher, insbesondere wenn sich die Ankerplatte in einem Nahbereich des zugeordneten Elektromagneten befindet, den Anker anzieht. Der mindestens eine Permanentmagnet ist auf einer der Ankerplatte abgewandten Seite der Spule des zugeordneten Elektromagneten angeordnet.
