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 (k1) and a second spring having a second spring constant (k2).

Abstract: A damping force variable valve assembly includes a spool (144) which is moved by a magnetic force, a spool guide (145) which surrounds the spool (144), valve bodies (151, 152), a main valve (150), a back pressure chamber (160) which is formed at the back of the main valve (150), and an elastic opening/closing portion which is installed in the valve body to open and close a pressure adjustment passage (180) communicating the inside of the back pressure chamber (160) with the outside of the back pressure chamber (160). Due to the interaction between the spool (144) and the spool guide (145), the damping force of the shock absorber is variable between a hard mode in which the back pressure of the back pressure chamber (160) is increased and a soft mode in which the back pressure of the back pressure chamber (160) is decreased.
