Electromagnetic valve actuator in an internal combustion engine

摘要

The valve activator comprises an electromagnet (1) comprising a supply reel (2) and a magnetic armature (15) connected to a valve (17) driving part (16) against the action of a commutation energy storage spring (18,19). A permanent magnet (5) interposed in the electromagnet body has its magnetization combined with the field generated in the body by the supply reel.
