Abstract
An electrically or electromagnetically operated valve has a movable structural group with a magnetic armature, which is movable along an axis between a first and a second position to open or close the valve. The valve has a valve sleeve in which the magnetic armature is movable between the first and the second position, the magnetic armature defining on its axial sides two volumes in the valve sleeve. There is provided a throttling element elastic in the radial direction, which is arranged between the first volume and the second volume such that upon axial movement of the movable structural group it throttles an air stream between the first volume and the second volume in order to decelerate a movement of the movable structural group.
