The invention relates to a sealing arrangement with an elastic sealing ring, which is located in sealing fashion between a first and a second component in a continuous groove ( 3 ) running around the first component, and is compressed in the groove in installed state, deforming its cross-section. At least one supporting ring ( 21, 22 ) is provided, one sealing surface ( 10 ) of which lies in sealing fashion against the sealing ring, while an opposite, supporting surface ( 9 ) lies against a groove flank ( 6 ) on the supporting-ring side. According to the invention, the groove and the supporting ring each have an essentially triangular cross-section, where the supporting ring ( 21, 22 ) is positioned by the compressed sealing ring ( 2 ) in its position at the gap ( 13 ) to be sealed between the first and second components. As a result, extrusion of the sealing ring through the gap provided between the two components to be sealed is prevented, the service life is increased, and sealing rings that are less complex to manufacture can be used. The groove base ( 8 ) can be of arc-shaped design, with a radius that is roughly equal to, or greater than, the radius of curvature of the sealing ring. The supporting ring can display a concave area. A defined gap ( 27 ) can be left between supporting ring and sealing ring. (<FIGREF IDREF="DRAWINGS">FIG. 4</FIGREF>)
