Abstract:
An electromagnetic valve actuator system for controlling the operation of a valve in an internal combustion engine comprising a valve having a valve stem with a valve head at one end. The valve is reciprocable along the longitudinal central axis of the valve stem to alternatingly move the valve head between a first position and a second position. A first coil is positioned on a first laminated core having a gap and a thickness. A second coil is positioned on a second laminated core having a gap and a thickness. The gaps of the first and second cores are aligned. An armature on the valve stem passes through the gaps of the first and second laminated cores, such that when the armature is centered in either of the gaps at least a portion of the armature extends slightly passed the thickness of the other laminated core.
