Abstract
The invention relates to a pressure regulator () in a shock absorber valve. The pressure regulator () comprises an axially movable first valve part () and a first seat (), which are arranged in a valve housing () in such a way that an adjustable flow opening is created between the parts (). The flow opening is arranged to restrict a damping medium flow (q) and its flow opening size (s) is determined by a force balance on the first valve part (). The force balance is principally or partially created by the sum of an actuating force (F) and the force (Fs) from a spring arrangement counter to the action of a counter holding regulator force (R). The spring arrangement comprises a first spring () having a first spring constant (k) and a second spring () having a second spring constant (k). The counter holding regulator force (R) is determined by the spring characters of both the first and the second spring (), in which the first spring () interacts with the actuating force (F) throughout the stroke (S) and the second spring () works in series with the first spring () in an initial stroke (S) close to the seat (), in which the size of the initial stroke is determined by the working range of the second spring ().
