Abstract: A sealing ring comprising a sealing sleeve that is made of a polymeric material and is essentially L-shaped. A fastening region extends essentially in a radial direction and a sealing region extends essentially in an axial direction. The sealing region surrounds, in sealing manner, a surface of a machine element to be sealed by exerting radial tension. The sealing region has, on the side facing the surface, at least one back-feeding device for conveying a medium to be sealed in the direction of the space to be sealed off. The back-feeding device has a profile with a volumetric delivery that decreases from the space to be sealed off in the direction of the surroundings.

Abstract: A sealing ring for sealing a shaft relative to an interior space. The sealing ring includes a supporting ring and a sealing disc attached to the supporting ring. The sealing disc includes a projection conically deformed in an axial direction of the shaft and has a first section in contact with the shaft. The first section includes a helical groove configured to allow return of a medium toward the interior space and a web separating adjacent turns of the helical groove. The groove has a trapezoidal cross section and/or a cross section larger than a cross section of the web.
