This innovative assembly utilizes a garter spring mounted in a circular groove that is concentric with the valve axis. A rotator plate is positioned on the garter spring, allowing it to turn incrementally through a small arc each time the valve completes its opening and closing cycle. Additionally, concentric coil compression springs are employed to resist the opening movement of the poppet valve. Both springs are supported by a valve retainer that rests on the rotator plate, ensuring that the lower ends of the springs are maintained at the same elevation. The springs are further centralized by integral fingers struck from the retainer ring, which helps to hold one or both springs in a central position.
