Abstract
A rotator assembly for a poppet valve employed in an internal combustion engine employs a garter spring mounted in a circular groove concentric with the valve axis. A rotator plate rests on the garter spring so that the plate turns incrementally through a small arc each time the valve completes its opening and closing cycle. Concentric coil compression springs resist opening movement of the poppet valve and both of these springs are supported by a valve retainer which rests on the rotator plate. The lower ends of both springs are supported at the same elevation and the springs are centralized by means of integral fingers struck from the retainer ring to hold one or both springs in central position.
