Abstract
Valve arrangement for a shock absorber is described, comprising a valve housing () having a first () and a second port (), a pilot chamber () being in fluid communication with the first () and/or second port (), wherein a pilot pressure (Pp) is defined by a hydraulic pressure in the pilot chamber (). The arrangement further comprises a main valve member () being axially movably arranged in the valve housing () and being arranged to interact with a main valve seat member () in order to restrict a main fluid flow between the first () and second ports () in response to the pilot pressure (Pp) acting on the main valve member (). Moreover, the main valve seat member () is movable between a first compression stroke position and a second rebound stroke position so that, during the compression stroke, the main fluid flow is restricted at a first restriction (R) and a cooperating serially arranged second restriction (R), and during the rebound stroke, the main fluid flow is restricted at a third restriction (R).
