Abstract
A valve has a valve member and an actuating member supported on the valve member by a mounting pin for actuating movement, wherein the pin has an axis extending between opposite ends thereof and the actuating member is connected to the pin intermediate its ends. The pin is supported on the valve member by a resilient coupling assembly including a support ring engaging the opposite ends of the pin and floating on a wave spring seated on a second support ring which is screwed to the valve member so that forces applied to the pin perpendicular to its axis will translate the pin against the spring rather than bend the pin. The second support ring is welded to a retaining ring and cooperates therewith to retain the spring and the first support ring in an integral cartridge module which can be mounted as a unit on the valve member.
