Abstract
The problem of flow induced instability in a control valve for a vehicle damper is solved by a generally tubular shaped valve spool having an open, bridged, flow-through end, rather than side flow openings. The flow-through end of the spool has a narrow flat edge oriented perpendicularly to the axis of the spool, with an inside surface of the spool forming a 55 to 90 degree angle with the flat edge, and meeting the flat edge in a sharp corner.
