| 摘要 |
The invention relates to a sealing ring for sealing two components moving relative to each other, particularly as a rotary shaft seal or piston ring, with a radially internal or external sealing surface ( 2 ) that can be brought into contact with one of the components to form a seal against a fluid medium, where, to the side of the sealing surface ( 2 ), the sealing ring displays a pressurizing surface ( 8 ) to be pressurized by the fluid medium and, on the opposite side, a supporting surface ( 7 ) to the side of the sealing surface ( 2 ) for positioning against a groove flank of a component accommodating the sealing ring. The pressurizing surface ( 8 ) and/or the supporting surface ( 7 ) are inclined relative to the sealing surface ( 2 ) and enclose an angle of less than 90° towards it, where the ring is capable of radial compression towards a radially internal sealing surface ( 2 ), or of expansion towards a radially external sealing surface ( 2 ).
