  • Patent number: 6971231
    Abstract: A piston assembly for a magneto-rheological fluid damper is provided that exhibits good sealing properties at elevated temperatures. The piston assembly comprises a piston rod having an axial bore therethrough, a piston core coupled to a distal end of the piston rod for movement thererwith, an electrical terminal located on the piston core, a conductor, a sealing member and a support member. The conductor is coupled to the terminal to form an electrical connection and passes through the bore in the piston rod. The sealing member is adjacent to the distal end of the piston rod for preventing the penetration of fluid into the bore. The support member is located and sized to block an opening into the bore to prevent the sealing member from being forced through the opening when the piston assembly is subjected to pressure.

  • Patent number: 6840358
    Abstract: A motor vehicle strut and a rod guide assembly for the same. The strut includes a body, a rod slidable within the body, and a guide assembly. The guide assembly includes a housing assembly with a compliant member positioned adjacent a sleeve. An aperture is formed within the housing assembly. A bearing receives the rod, is positioned substantially within the aperture, and engages the sleeve. At least one seal is positioned substantially within the aperture. A seal cover and a retainer are operably attached to the housing assembly. Lateral movement of the rod causes deformation of the compliant member.
