Abstract
An electromagnetic actuator operating a cylinder valve of an internal-combustion engine includes first and second spaced electromagnets having pole faces oriented toward one another; an armature arranged for reciprocating motion between the pole faces; and a connecting rod having a first rod part being in an abutting contact with a first side of the armature and being a component separate therefrom. The abutting contact is such as to prevent a torque transmission between the first rod part and the armature. The connecting rod has a second rod part which is rigidly affixed to a second side of the armature and extending towards the cylinder valve. There are further provided a first spring situated adjacent the first electromagnet externally thereof and arranged for urging the first rod part into the abutting contact with the armature for urging the armature away from the first pole face towards the second pole face; and a second spring situated adjacent the second electromagnet externally thereof and arranged for urging the armature away from the second pole face towards the first pole face. The first and second springs act oppositely such that in a de-energized state of the first an…
