Abstract
A valve spring top collar is formed by a unitary body having a circular top face and a bottom surface, with a first circular shoulder extending downwardly from the bottom surface of the body and a second inwardly spaced circular shoulder. The shoulders are inserted into the valve springs so that the springs cannot slip off the collar in a radial direction. A central aperture extends through the central core of the body, through which a valve stem is inserted. A plurality of peripheral apertures extend through the body about the central aperture, thereby decreasing the total weight of the collar and allowing flow of lubricant to the springs.
