    摘要: A valve operating system in an internal combustion engine, that can be readily assembled and installed on the engine, including a casing coupled to an upper surface of a cylinder head, an armature, a pair of electromagnets for exerting electromagnetic forces on the armature in directions of opening and closing of an engine valve, and a pair of resilient means for biasing the engine valve in the opening and closing directions, respectively, and for retaining the armature at a predetermined neutral position by cooperation with each other during deenergization of both the electromagnets. The resilient means for closing the engine valve is mounted between a retainer fixed to the valve stem and a fixed position on the cylinder head, and the electromagnets are fixed within the casing which is constructed so that an upper portion of the stem can be inserted into the casing. Accommodated within the casing are the armature separatably coaxially connected at an upper end of the stem, and the resilient means for opening the engine valve and also exhibiting a resilient force for urging the armature against the first electromagnet to support the armature, when the armature is not connected to the stem.
