Abstract
An electromagnetic actuator having an annular pole piece and an annular armature with surfaces formed thereon through which a magnetic flux passes. The armature is axially movable relative to the pole piece between a first position and a second position. Magnetic flux is efficiently transmitted between the pole piece and the armature and the pole piece can be employed to guide the armature for movement thereon.
