Electromechanical valve activator for internal combustion engine, has magnet and coil switching magnetic plate between electromagnet adjoining and distant positions following delay controlled by current variation flowing in coil

摘要

The activator has a polarized electromagnet (700) and a mobile magnetic plate (706) switching between a position adjoining the electromagnet and a position distant from the electromagnet. A magnet and a coil (708) switches the plate between the positions following a delay controlled by a current variation flowing within the coil of the electromagnet and determined based on an operation state of an internal combustion engine. An independent claim is also included for an internal combustion engine.
