Abstract (en)

[origin: EP1450009A2] The actuator has an electromagnet (108 1) and a magnetic plate (114 1) whose movement controls the movement of a valve of an internal combustion engine. The parameters of the magnetic circuit formed by the magnet and the plate enable a part of the circuit to be in a saturation state when the plate is at proximity of the electromagnet. The plate strangulates a conservative magnetic flux generated by the magnet. An independent claim is also included an internal combustion engine having a valve controlled by an actuator.
