摘要： An electromagnetic actuator for the actuation of the intake or exhaust valves of an internal combustion engine in which an oscillating arm has a first end hinged on a support frame secured to the engine head and a second end in abutment on the upper end of the stem of the intake or exhaust valve; two electromagnets being provided in order to move, on command, the oscillating arm in order axially to displace the valve between a closed position and a position of maximum opening, the oscillating arm comprising a central plate positioned in the space between the polar heads of the two electromagnets, a cylindrical tubular member rigid with a lateral edge of the central plate and a projection extending in a projecting manner from the central plate on the side opposite the cylindrical tubular member, the central plate being formed by a pack of sheets of ferromagnetic material stacked on one another and seam welded on the outer lateral surface of the cylindrical tubular member and by a stiffening rib welded to the pack of sheets on the side opposite the cylindrical tubular member.
