Abstract
The invention relates to a sealing ring for sealing two components moving relative to each other, particularly a rotary shaft seal or piston ring, with a radially internal or external sealing surface that can be brought into contact with one of the components to form a seal against a fluid medium. On one side of the sealing surface the sealing ring displays a pressurizing surface to be pressurized by the fluid medium and, on the opposite side, a supporting surface to the side of the sealing surface for positioning against a groove flank of a component accommodating the sealing ring. The pressurizing surface and/or the supporting surface are inclined relative to the sealing surface and enclose an angle of less than 90° towards it, where the ring is capable of radial compression towards a radially internal sealing surface, or of expansion towards a radially external sealing surface.
