Abstract
An adjustable damping valve device includes a coil carrier with a coil which is wound on an inner sleeve and which has two wire ends which protrude over a winding body. A back iron having a passage for a power supply line of the coil is placed on the coil carrier. The wire ends of the coil are co-located adjacent to one another in an outlet area of the coil carrier, and the back iron has a radial slot which extends from the outer edge of the back iron to the passage and has a width which corresponds at least to the width of the outlet area.
