ABSTRACT:
An axially and radially clamping spreader ring for an oil scraper piston ring, comprises a profiled metal band which has been made resilient in the circumferential direction by corrugations and/or cuts. The two ends of the metal band abut against one another and the metal band is provided in the area of one side with axial and radial supporting faces to accommodate at least one band-shaped scraper ring. A plurality of radially outwardly extending protrusions are distributed over the circumference of the band in the vicinity of the side of the spreader ring which is axially opposite the side which accommodates the scraper ring. The protrusions are separated from one another by wide lubricating channels and, when installed, contact the cylinder wall.
