Abstract

An electrically adjustable hydraulic shock absorber includes a piston positioned within a tube that divides a fluid chamber into a first working chamber and a second working chamber. A piston rod is attached to the piston and projects. An electronically-controlled valve is positioned within a rod guide. A circuit board is in communication with the electronically-controlled valve. A carrier includes an inner wall and an outer wall interconnected by a bottom wall thereby defining a pocket. A circuit board is positioned within the pocket.
