ABSTRACT:
A valve actuator for an internal combustion engine is described having a core having a wound coil located therein, said core further having at least one permanent magnet located at least partially inside or outside said coil and positioned at an angle relative to a direction of movement of an armature. Further, various recesses, indentations, chamfers, bevels, and/or depressions may be included to affect flux leakage, and/or force generation.
