An oil scraper ring spring for an oil scraper ring comprising the oil scraper ring spring, an upper metal ring and a lower metal ring and provided for being mounted in an oil ring groove of a piston, comprising: a plurality of upper regions and a plurality of lower regions arranged in alternating manner in a circumferential direction so as to be spaced in an axial direction; connecting regions, each connecting adjacent upper and lower regions (5, 7) to each other; wherein each of the upper and lower regions (5, 7) includes: a nose section disposed at an inner circumferential end and adapted to push the respectively abutting upper or lower metal ring (21, 22) radially out - wardly and having a through-opening; an abutment section extending between the nose section and the outer circumferential end and configured to have either the respective upper metal ring abutting thereon or the respective lower metal ring abut - ting thereon; wherein the abutment section has a recess formed therein, characterized in that the abutment section extends radially between the nose section and the outer circumferential end; the depth of the recess relative to the abutment area of the abutment section increases in a radial direction towards the through-opening; the width of the recess in the abutment section increases in the ra - dial direction towards the through-opening; the recess in the abutment section has a shape substantially of a half-funnel; the half-funnel has an opening angle in a range of 30° to 150°, in particular of 30° to 60°, or wherein upper side edges of the recess span an angu - lar segment in a range of 5-50°, in particular of 5-15°; and the increase in depth and width of the recess radially inwardly together with the through-opening serves to increase and accelerate the oil flow to the piston centre. a plurality of upper regions and a plurality of lower regions arranged in alternating manner in a circumferential direction so as to be spaced in an axial direction; connecting regions, each connecting adjacent upper and lower regions (5, 7) to each other; wherein each of the upper and lower regions (5, 7) includes: a nose section disposed at an inner circumferential end and adapted to push the respectively abutting upper or lower metal ring (21, 22) radially out - wardly and having a through-opening; an abutment section extending between the nose section and the outer circumferential end and configured to have either the respective upper metal ring abutting thereon or the respective lower metal ring abut - ting thereon; wherein the abutment section has a recess formed therein, characterized in that the abutment section extends radially between the nose section and the outer circumferential end; the depth of the recess relative to the abutment area of the abutment section increases in a radial direction towards the through-opening; the width of the recess in the abutment section increases in the ra - dial direction towards the through-opening; the recess in the abutment section has a shape substantially of a half-funnel; the half-funnel has an opening angle in a range of 30° to 150°, in particular of 30° to 60°, or wherein upper side edges of the recess span an angu - lar segment in a range of 5-50°, in particular of 5-15°; and the increase in depth and width of the recess radially inwardly together with the through-opening serves to increase and accelerate the oil flow to the piston centre. a nose section disposed at an inner circumferential end and adapted to push the respectively abutting upper or lower metal ring (21, 22) radially out - wardly and having a through-opening; an abutment section extending between the nose section and the outer circumferential end and configured to have either the respective upper metal ring abutting thereon or the respective lower metal ring abut - ting thereon; wherein the abutment section has a recess formed therein, characterized in that the abutment section extends radially between the nose section and the outer circumferential end; the depth of the recess relative to the abutment area of the abutment section increases in a radial direction towards the through-opening; the width of the recess in the abutment section increases in the ra - dial direction towards the through-opening; the recess in the abutment section has a shape substantially of a half-funnel; the half-funnel has an opening angle in a range of 30° to 150°, in particular of 30° to 60°, or wherein upper side edges of the recess span an angu - lar segment in a range of 5-50°, in particular of 5-15°; and the increase in depth and width of the recess radially inwardly together with the through-opening serves to increase and accelerate the oil flow to the piston centre.
