Abstract
An actuator for an assembly in a motor vehicle may have a moving armature in an armature chamber, where the actuator has a fluid path that is configured for fluid transfer between the armature chamber and a fluid reservoir in the assembly when the actuator is installed in an assembly, where the actuator is configured to fill the armature chamber with fluid, in particular oil, when the armature moves axially, thereby drawing fluid into the armature chamber when the actuator is operated in a fluid chamber, in particular an oil chamber.
