Abstract
A piston ring assembly has a ring-shaped expander spring composed of an annular body defining an axial direction and presenting a circumferential main bending region and a plurality of resilient tongues extending radially outwardly from the main bending region and adjoined, adjacent the main bending region, by generally axially extending parts of the annular body. The assembly further has a lamina lying, at least in part, on the tongues and is radially supported by the axially extending parts. The main bending region is disposed radially inwardly of the lamina.
