More Information
Summary:An oil wiper ring, comprising a body with a radially external running surface, an inner circumferential surface and an upper and lower face, and which possesses at least two slide ribs, which may be provided with a wear-resistant layer, such ribs becoming conically thinner, in the radial direction of their end faces, and which are opposite a sliding mating surface, such that they proceed from the body, at a specifiable angle, in order to form an angled side face, so that the free end of each slide rib, commencing in the region at the oil chamber side, is shaped to slope towards an area at the combustion chamber side, such that the associated transitional areas, on the one hand, from the region of the circumferential slide rib towards the angled side faces, and on the other hand, from the angled side faces to the piston ring body, are rounded, i.e. have predetermined radii.
