Beschreibung
Zusammenfassung:	A piston valve assembly for a damper comprises a piston having a central hole and a fluid passageway spaced from the hole. A deflection disc having a central aperture is aligned with the hole. The deflection disc is arranged adjacent to the piston and at least partially blocks the fluid passageway for regulating the flow of hydraulic fluid between the fluid chambers when installed in the damper. A hub, common across different dampers, includes a neck that is arranged in the hole and the aperture of the deflection disc. A retainer abuts an unthreaded outer surface of the hub. During assembly, the retainer is received on the cylindrical outer surface in a slip fit relation. The deflection disc and pistons are loaded to a predetermined clamp load. The retainer is secured to the outer surface by a securing material such as a weld bead.
