Abstract
An electromagnetic actuator having an annular pole piece and an annular armature with surfaces formed thereon through which a magnetic flux passes. One of the annular pole piece and the annular armature is axially movable relative to the other between a first position, in which the surfaces are spaced axially apart by a minimum distance, and a second position in which the surfaces are spaced axially apart by a maximum distance. The surfaces axially overlap one another but do not touch when the one of the annular pole piece and the annular armature is positioned in the first position and in the second position.
