Abstract
An electromagnetic actuator () for an assembly, which has a fluid space configured to be fluidically connected to the actuator when the actuator is installed in the assembly, includes a movable armature in an armature space (). The armature includes a movable armature rod (). The actuator is configured to fill the armature space () with fluid, such as oil, via axial movements of the armature rod that draw fluid from the fluid space into the armature space () through a fluid path when the armature rod is fluidically connected to the fluid space.
