A vehicle suspension damper comprising: a damping chamber containing a damping fluid, and a piston and a piston rod moveable in a damping cylinder; a valve for controlling movement of said damping fluid in compression and/or rebound of said vehicle suspension damper, the valve having: a primary valve member for resisting damping fluid flow along a first fluid flow path from a first side of the valve to a second side of the valve; a first pressure reducing means and a second pressure reducing means in a second fluid flow path between said first and second sides of the valve; wherein a surface of the primary valve member is exposed to damping fluid in said second fluid flow path between said first and second pressure reducing means; the arrangement being such that, in use, during compression and/or rebound of said vehicle suspension damper damping fluid is urged to flow through said first fluid flow path at a first fluid pressure resisted by said primary valve member, and at the same time pressure of damping fluid in the second fluid flow path is reduced by the first and second pressure reducing means to a second fluid pressure lower than said first fluid pressure; and the second fluid pressure acts on said exposed surface of said primary valve member so that the primary valve member increases its resistance to damping fluid flow along said first fluid flow path; wherein said second pressure reducing means is adjustable whereby, in use, adjustment of said second pressure reducing means effects a corresponding adjustment of said second fluid pressure, and thereby a corresponding change in the resistance by said primary valve member to damping fluid flow along said first fluid flow path; characterized in that said second pressure reducing means comprises a spool valve controlled by a magnetic latching solenoid. a damping chamber containing a damping fluid, and a piston and a piston rod moveable in a damping cylinder; a valve for controlling movement of said damping fluid in compression and/or rebound of said vehicle suspension damper, the valve having: a primary valve member for resisting damping fluid flow along a first fluid flow path from a first side of the valve to a second side of the valve; a first pressure reducing means and a second pressure reducing means in a second fluid flow path between said first and second sides of the valve; a primary valve member for resisting damping fluid flow along a first fluid flow path from a first side of the valve to a second side of the valve; a first pressure reducing means and a second pressure reducing means in a second fluid flow path between said first and second sides of the valve; wherein a surface of the primary valve member is exposed to damping fluid in said second fluid flow path between said first and second pressure reducing means; the arrangement being such that, in use, during compression and/or rebound of said vehicle suspension damper damping fluid is urged to flow through said first fluid flow path at a first fluid pressure resisted by said primary valve member, and at the same time pressure of damping fluid in the second fluid flow path is reduced by the first and second pressure reducing means to a second fluid pressure lower than said first fluid pressure; and the second fluid pressure acts on said exposed surface of said primary valve member so that the primary valve member increases its resistance to damping fluid flow along said first fluid flow path; wherein said second pressure reducing means is adjustable whereby, in use, adjustment of said second pressure reducing means effects a corresponding adjustment of said second fluid pressure, and thereby a corresponding change in the resistance by said primary valve member to damping fluid flow along said first fluid flow path; characterized in that said second pressure reducing means comprises a spool valve controlled by a magnetic latching solenoid.
