<p>The actuator (1) has a movable unit movable under the effect of a magnetic field created in a ferromagnetic chassis (2) with respect to which the movable unit is mounted in translation on itself. The chassis has a central core (16) extending transversely from one to the other of two longitudinal walls of the chassis. The movable unit includes a rod slidably mounted around the core and bearing on both sides of two permanent magnets (6, 7). The magnetic magnets are fixed at electromagnet air gaps formed by transverse walls of the chassis on both sides of the central core.</p> |
