摘要： The present disclosure relates to a valve arrangement (1) for improved high frequency performance. The valve arrangement (1) comprises: a valve seat member (2) adapted in size and shape to define a valve seat (21) and a flow-through opening (20); a valve member (3) adapted to be displaceable relative the valve seat (21) along a displacement axis (A) during use in response to a damping fluid pressure force overcoming an opening force threshold, wherein said damping fluid pressure force is provided by damping fluid pressure acting on an inlet side of the valve member (3), said opening force threshold being at least partly adjustable by means of a force actuator (9), wherein the valve member (3) and the valve seat member (2) are adapted to provide a chamfer restriction (22, 32) provided with an opening crosssection which decreases from an inner lateral position to an outer lateral position relative the displacement axis (A). A shock absorber (1000A, 1000B) comprising said valve arrangement (1) and a method for adjusting damping fluid flow is disclosed also.
