摘要：
An electromagnetic actuator, particularly for operating a cylinder valve of an internal-combustion engine, includes an electromagnet for generating an attracting electromagnetic force; an armature movable into contact with and away from the electromagnet; a spring arrangement connected to the armature and opposing the electromagnetic force; and a sound muffling device attached to the electromagnet for reducing sound transmission by body vibration from the electromagnet.
