Abstract
A frequency dependent piston assembly (1) for a shock absorber comprising:a piston (10) slidably disposed within a portion of cylinder (20), dividing volume defined within said portion of cylinder (20) into a first chamber (21) and a second chamber (22), said piston (10) comprising a flow channel (11) connecting said first chamber (21) and said second chamber (22); characterized in that said piston assembly (1) further comprises:a valve assembly (100) controlling fluid flow (150) between said first chamber (21) and said second chamber (22), configured for its preload to be changed by movement of said piston (10);a pressure chamber (300) comprising a chamber wall (301), configured to be moved by said piston (10) to change volume of said pressure chamber (300).
