ACTIONNEUR MAGNETIQUE A EFFICACITE AMELIOREE

摘要

The invention relates to a magnetic actuator having a closed magnetic circuit comprising a mobile magnetic part (22) and a fixed magnetic part (21) which are magnetically interconnected and which define at least one gap (26). Said magnetic circuit can guide a magnetic flux, thereby enabling the mobile magnetic part (22) to be moved towards the fixed magnetic part (21). The mobile magnetic part (22) is flexible and comprises at least one zone (31) having a variable section that is perpendicular to the magnetic flux.
