摘要： In a method and apparatus for coupling or decoupling two actuating elements of a valve drive of an internal combustion engine for operating a gas exchange valve, comprising a locking element movable between two end positions for coupling the actuating elements, an electromagnet for actuating the movable locking element, a permanent magnet is associated with the armature for holding the armature and the locking element in one end position and means for biasing the armature and the locking element in the opposite end position, the electromagnet is energizable in one sense for moving the armature into one end position in which the armature is retained by the permanent magnet with a force greater than a counteracting force generated by the biasing means, and in the opposite sense so as to generate a force exceeding that of the permanent magnet for moving the armature in the opposite end position, where it is retained by said biasing means.
