Abstract
1296289 Piston rings RAMSEY CORP 27 Aug 1971 40320/71 Heading F2T In a U-section piston ring 10 split to provide at least one gap 17, 18 and comprising radial walls 11 interconnected by a peripheral wall 12, the peripheral wall terminates short of the gap on both sides thereof and the ring is urged outwardly by spring means extending from the ends of the wall radially inward and then radially outward. On each side of the gap 17 the wall 12 is formed as a hairpin leaf spring 19, 20, the radially outward legs 19c, 20c abutting each other. The ends of the wall 12 on opposite sides of the gap 18 are connected by a single wavy leaf spring 21. Beads 14 project radially outward from the wall 12 which has oil drainage slots 13 therein. In use, Fig. 5, the ring 10 is mounted in a groove 22 in the piston 23 with the springs 19, 20 and 21 projecting freely through oil return slots 27. In a modification, Fig. 7 (not shown), the springs 19, 20 are replaced by a single spring (30) similar to the spring 21. In a further modification, Figs. 8-10 (not shown), the ring (10b) is formed by two semi-circular cast or forged segments (40) connected by separate springs (49, 50, 51) welded or otherwise secured to the ends of the walls (42) of the segments. In a further modification, Fig. 11, spring means 51 is provided at one gap 48 only.
