The present invention relates to a device in a vehicle damper which comprises a damping medium-filled damper body (2), in which an element (5, 5′) forming a seal against the damper body divides the damper body into two chambers (2a, 2b). A microprocessor control unit (SU) is coupled to one or more valve and connecting arrangements (4a, 4b, 4c), comprising at least one valve and a number of flow ducts. Respective valves and flow ducts of the valve and connecting arrangement (4a, 4b, 4c) are coupled both to respective damper chambers (2a, 2b) and a pressurizing element (3) common to both of the chambers, so that even in the chamber in which a low pressure prevails there is a positive pressure acting at all times. The valve and connecting arrangements (4a, 4b) comprise a continuously electrically controlled main valve (CES), a non-return valve (SV) and one or more bleed valves (BV, 10a, 10b), the flow through the bleed valve(s) (BV, 10a, 10b) being adjustable separately from the electrically controlled main valve (CES). In the case of small strokes or slow movements the damping medium flows via the bleed valve (BV, 10a, 10b) through one or more separate leakage flow ducts. By locating the leakage flow duct(s) parallel to the valve and connecting arrangement (4a, 4b, 4c) the low-speed damping can be adjusted separately from the high-speed damping. The electrically adjustable main valve (CES) can therefore be adjusted to the correct damping characteristic whilst the damper is set up for small strokes and slow movements.
