  • Patent number: 11990275
    Abstract: An electromagnetic actuator includes an armature (18) movable axially relative to a stationary core (14) as a reaction to energizing of a stationary coil (12) in an actuator housing (10). The armature (18) is gripped by an axially extended slide (20) guided in a core passage (50) of the core such that a movement of the armature in the direction of the core entrains the slide. An end section (26) of the slide, axially opposite the armature, cooperates with an adjusting partner, the slide having a long rod section (34) and a disk-type end section (30) with a widened diameter on the rod section, on the end in the direction of the armature (18), the axial extension (W) of the end section determining a minimum distance between the armature and the core in an abutment state of the armature on an end surface and/or front surface of the core, facing the armature.
