ABSTRACT:
A ring assembly includes two side-by-side flat ring members of uniform rectangular cross-section each being split, with the confronting split ends having radially overlapping fingers to define a circumferentially sealing joint. The ring members are dimensioned to be received in a common piston groove with the ring members being non-rotatably coupled so that the joint of one member will always be rotationally spaced from the joint of the other to define an axial seal for the ring assembly. A non-rotational coupling is provided by an integral tab formed in one member and projecting transversely therefrom and received in a mating transverse recess in the other member, with the recess having a larger dimension than the tab to permit sliding movement of the ring members relative to each other within the groove. Two forms of tabs include a partially sheared and bent tab and a partially displaced shear plug.
