Beschreibung
Zusammenfassung:	A damper is shown for damping the movements of a valve spring in an engine. The valve spring can be housed within the damper or the damper may be located inside of the valve spring. The damper is made from a suitable polymer and has one or more tabs or slots located radially to a central axis and one or more helical springs, rings or bands housed in the slots or between the tabs. The helical springs, rings or bands are located on the outer surface of the damper where the valve spring is housed within the damper. The cross section, number and location of the tabs, slots, helical springs, rings or bands can be adjusted depending on the particular application of the damper and the amount of damping that is desired for the particular application. The damper can also incorporate a hub or stem seal and ports for receiving oil.
