ABSTRACT:
A piston ring formed of an annular, cross-sectionally bent metal strip has a series of circumferentially distributed slots extending in a generally axial orientation from edges of the strip. The slots are in an overlapping relationship when viewed circumferentially for defining a series of circumferential, resilient webs. The webs have web portions that are readily deformable to bending forces.
