Abstract
A vehicle damper comprises a damping medium-filled damper body in which an element divides the damper body into two chambers. A microprocessor control unit is coupled to one or more valve and connecting arrangements that comprise at least one valve and a number of flow ducts. Respective valves and flow ducts of the valve and connecting arrangement are coupled both to respective damper chambers and a pressurizing element 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 comprise a continuously electrically controlled main valve, a non-return valve and one or more bleed valves.
