Abstract
An electromagnetic valve actuator for a cylinder valve, including a pair of electromagnets including magnetic cores and coils serially connected and wound around the magnetic cores in the same direction. An armature is moveable against biasing forces of springs in one direction to open the cylinder valve and in the opposite direction to close the cylinder valve. A permanent magnet is prevented from being undesirably influenced by an opposing magnetic field relative to the permanent magnet.
