Beschreibung
Zusammenfassung:	According to the present invention there is provided a hydraulic damper assembly including a housing that extends about and along an axis and defines an interior wall and a chamber for holding a fluid. A piston assembly is disposed in the chamber and axially moveable therein. The piston assembly includes a core. A wear band is disposed about the core and has an inside surface and an outside surface. The inside surface of the wear band defines at least one groove in fluid communication with the chamber for allowing the fluid to bias the wear band toward the interior wall of the housing during the passage of the fluid though the at least one groove during movement of the piston assembly.
