Abstract (en)
[origin: WO2007080301A1] The invention relates to an electromagnetic actuator comprising an actuating member associated with an armature (4) and able to move under the action of at least one electromagnet, a coil (3), a core (2) suitable for channelling a flux of the coil, so that said flux closes within the armature, the core comprising a base (10) from which branches extend, including a central branch around which the coil extends, and two permanent magnets (13) which are associated with the core. According to the invention, the two permanent magnets are placed in the central branch of the core in order to form a V, which separates the central branch into two parts, so that any section (S1, S2, S3) of the core (2) or of the armature (4) through which the flux from one or other of the permanent magnets can pass, has an area large enough to prevent saturation by this flux.
