  • Vehicle suspension damper including floating piston
    Patent number: 11904647
    Abstract: A shock for a vehicle includes a tube elongated along an axis. A piston is disposed in the tube and is moveable relative to the tube along the axis. A rod is connected to the piston. A floating piston is spaced from the piston along the axis and is moveable relative to the tube along the axis. The tube defines a working chamber between the piston and the floating piston. The tube defines a gas chamber. The floating piston separates the gas chamber from the working chamber. The floating piston has a housing slideably engaged with the tube and a membrane fluidly separating the working chamber from the gas chamber. The membrane is flexible relative to the housing.
    Type: Grant

  • Damper with printed circuit board carrier
    Patent number: 10588233
    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.
