Abstract

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 slots located radially to a central axis and one or more rings or bands. The slots can be parallel to the central axis or cut at an angle or curve in the wall of the damper. The rings or bands are located on the outer surface of the damper where the valve spring is located within the damper. The purpose of the slots cut into the polymer damper is to enable the polymer to deflect and conform to the shape of the spring under a radial force provided by a separate circular spring element such as a band, ring, garter spring and others. The rings or bands are located on the inner surface of the damper where the valve spring surrounds the damper. The cross section, number and location of the slots, 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.
