An electromagnetic actuator, particularly for use with valves in the automotive field, such as, for example, exhaust-gas recirculation valves, secondary-air valves, etc., having a housing with an electrical connector plug, a magnetic yoke, a coil unit, a guide element, a magnetic core and an armature that cooperates with a valve adjusting member. The armature is formed by first and second armature elements, the second armature element being in the form of a disk mounted so that it is spaced from the first armature element by an air gap when current is not supplied to the actuator whereby high, abrupt force is developed on the first armature element to open the valve when current is supplied.
An electromagnetic actuator, for a valve in the automotive field comprising a housing having an electrical connector plug, a magnetic yoke, a coil unit, a guide element, a magnetic core and an armature which operates a valve adjusting member, said armature including first and second armature elements, said second armature element being configured as a disk and being mounted in spaced relation from the first armature element when current is not supplied to the coil unit wherein the first armature element moves toward and contacts the second armature element and both armatures act together as a single armature as current is supplied.
