ABSTRACT:
A dual planar compression ring arrangement where first and second compression rings for fitting into a single groove of a piston coaxial with and abutting one another. The first ring has a flat surface provided with an axial projection for fitting into the gap of the second ring to prevent rotation of the ring gaps towards one another. The gap in the second ring is contoured to permit full closure of the second ring upon itself around the projection.
