Abstract

A locking element (22) is retained by an elastic lock (24) in the interior of a valve spring plate (20), and interacts with the plate to limit axial movement of the plate on the valve stem in one direction. An Independent claim is also included for a method in installing the valve spring assembly to a valve stem.
