  • Patent number: 9168808
    Abstract: The present invention is related to a damper device (1). More in particular, the present invention is related to a damper device for which the damping force can be varied using a magnetically actuated closing member (33) with which a bypass channel (15) can be closed or opened. According to the present invention, the magnetic reluctance of the magnetic loop for guiding the magnetic field (8) is configured such that a too strong of an upward bending of the magnetic force versus closing member displacement curve is prevented. This prevents the system from obtaining multiple settling points for the closing member for a given current value. Consequently, the damper device is more stable and the damping force offered by it can be controlled more accurately.
