Claim:
1. A pressure regulator for a shock absorber valve comprising: 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 first valve part and the first seat, and in which the flow opening is arranged to restrict a damping medium flow and the flow opening size of which is determined by a force balance on the first valve part principally or partially created by the sum of an actuating force and the force from a spring arrangement comprising a first spring having a first spring constant and a second spring having a second spring constant acting upon the movable valve part counter to the action of a counterholding pressure regulator force, wherein the counterholding pressure regulator force is determined by spring characteristics of both the first and the second spring, in which the first spring interacts with the actuating force throughout stroke and the second spring has a limited working range defined by possible axial deformability of the second spring such that it only interacts with the actuating force during an initial stroke; wherein the first spring is a shim spring having an inner and an outer spring part which are connected in at least two places to resilient bridges such that the outer and the inner spring part can spring in relation to each other and be displaced relative to each other; wherein the pressure regulator is configured to directly regulate a pressure to determine a damping medium flow.
