ABSTRACT:
A three-piece oil control ring including top and bottom rail rings and a circumferential spacer-expander is disclosed. The spacer-expander includes a plurality of spring elements interconnected by integral webs. Each of the spring elements is generally U-shaped in axial section and includes a top leg, a bottom leg and a base interconnecting the legs. The top leg defines a radial slot extending from the inner radial edge thereof along the entire radial length of the top leg. The bottom leg is slotless and the centroid of each spring element is located axially above the circumferential center line of the spacer-expander. A greater tension is exerted by the spring elements on the top rail ring than on the bottom rail ring.
