Abstract:
A compression piston ring  2  having a running-surface region  4,  an upper flank  6,  a lower flank  8  and also an inner circumferential surface  10,  wherein the running-surface region  4  is provided with a profiled section, which, as viewed over the axial height of the running-surface region  4,  comprises mutually spaced, convexly spherically constructed sections  12, 14  having an upper and lower apex So; Su, wherein a groove  16  with a depth Tn is arranged between the apexes So, Su, wherein both apexes So; Su are arranged, below a centre M of the piston ring  2  in the axial direction.

Claim (Index 1):
A compression piston ring having a running-surface region, an upper flank, a lower flank and also an inner circumferential surface, wherein the running-surface region is provided with a profiled section, which, as viewed over the axial height of the running-surface region, comprises mutually spaced, convexly spherically constructed sections having an upper and lower apex, wherein a groove with a depth is arranged between the apexes, wherein both apexes are arranged below a centre of the piston ring in the axial direction, wherein the spherical sections are arranged asymmetrically with respect to one another, with respect to the axial height of the running-surface region.
