The sealing ring has a sealing edge contacting the outer surface of the shaft toform a seal. The sealing edge extends circumferentially around the outer surface of theshaft in a sinusoidal fashion. The sealing ring has first and second surfaces which extendradially outward from the sealing edge and which diverge relative to each other as theyextend radially outward from the sealing edge. The first and second surfaces extendentirely circumferentially around the outer surface of the shaft. The first surface extendsat a constant first angle relative to said sealing edge throughout the entire
circumferential extent of the first surface and the second surface extends at a constantsecond angle relative to the sealing edge throughout the entire circumferential extent ofthe second surface.
