Abstract

1,222,609. Piston rings; shaft seals. ATLAS COPCO A.B. 31 Oct., 1968 [7 Nov., 1967], No. 51686/68. Headings F2B and F2T. Sealing means between two relatively movable members, e.g. a cylinder 1 and piston 3, comprises a first split ring 4 of L-section and a second split ring 5 of rectangular section which fits in the recess of the L-section ring to form a ring device of rectangular cross-section, the rings being arranged to break joint and prevented from relative rotation and being of elastic self-lubricating composition, e.g. PTFE, polyamide or polyacetal. In the embodiment shown the rings are locked peripherally by a pin 8. In another embodiment, Fig. 2 (not shown), an axial projection (12) on the ring (4) fits the gap (7) in the ring (5).
