Abstract (en)
[origin: WO2015059086A1] The invention relates to an electromagnetic actuator (10), which includes a ferromagnetic housing (12) extending in a longitudinal direction (X) and having a height (H1) in a vertical direction (Z) perpendicular to the longitudinal direction (X), two coils (14, 16) arranged inside the housing and each comprising at least one winding (36, 38) around the longitudinal direction (X), a ferromagnetic member (24) arranged between the coils, and a ferromagnetic plunger (22) subjected to a magnetic field generated by the coils, the plunger being movable in the longitudinal direction and suitable for being immobilized in three different longitudinal positions depending on the field generated by the coils. The ferromagnetic member (24) is rigidly connected to the housing (12) and has, in the vertical direction (Z), a size (H2) that is greater than one sixth of the height (H1) of the housing, the ferromagnetic member (24) being in addition located at a distance that is smaller than one fourth of a gap (E) in the longitudinal direction (X) between the two coils, relative to a median plane (P) that is perpendicular to the longitudinal direction and located at the midpoint between the two coils.
