Electromechanical valve control actuator for internal combustion engines

A valve actuator for internal combustion engines, comprising:

• at least one electromagnet having a coil and
• a magnetic plate, whose movement controls the displacement of the valve,
• wherein the parameters of the electromagnet and of the plate are such that at least part of the magnetic circuit formed by the electromagnet and the plate is in a state of magnetic saturation when the magnetic plate is in the proximity of the electromagnet, so as to minimize the force of attraction exerted on the plate and therefore its velocity;
• the parameters of the electromagnet and of the plate and the shape of the plate being such that the magnetic circuit is in the state of magnetic nonsaturation when the plate is located at a distance from the electromagnet, so as to maximize the force attraction exerted on the plate and therefore to minimize the switching time, wherein an air gap is provided between the electromagnet and the magnetic plate when the plate is adjacent to the electromagnet.
