ABSTRACT:
An electromechanical valve actuator for internal combustion engines, equipped with a polarized electromagnet and with a magnetic plate switches between a first position close to the electromagnet and a second position remote from the electromagnet, the switching times between these positions being determined depending on the operating state of the engine. The actuator supplies the electromagnet with a variable attracting current in the course of the approach of the plate to the electromagnet.
