Patent ID: 7516963

Claim:
A sealing arrangement comprising an elastic sealing ring, which is located between a first and a second component surrounding each other wherein a gap is formed between said first and said second component, wherein the sealing ring has a circular cross-section in its disassembled state with a radius and a sealing axis, where the sealing ring is located in a continuous groove, running around the inner or outer circumference of the first component, which displays a first and a second, opposite, groove flank and a groove base, wherein at least one supporting ring is further provided, one sealing surface of the at least one supporting ring lies in sealing fashion against the sealing ring, while an opposite, supporting surface lies against one of the first and the second, opposite, groove flanks on the supporting-ring side, wherein the groove displays an essentially triangular cross-section, with one corner of the cross-section forming the groove base, both groove flanks enclosing an angle of 60°-120° with each other, wherein at least the groove flank on the supporting-ring side is inclined relative to the sealing ring axis, wherein the at least one supporting ring displays an essentially triangular cross-section and, in installed state, a smaller height than the distance of the groove base from the second component, wherein the at least one supporting ring is positioned by the sealing ring, which is compressed in installed state, in its position at the gap to be sealed between the first and second components, wherein the groove base cross-section has a radius that is equal to the radius of the sealing ring when the sealing ring is inserted in the groove, wherein the sealing ring-side sealing surface of the at least one supporting ring is concave having a radius that is equal to the radius of the sealing ring, wherein the sealing surface of the at least one supporting ring and of the groove base transition into each other in such a way that they lie on a common arc of circle being the circumference of the arc of the circle of the sealing ring, wherein a continuous sealing surface is formed extending over the supporting ring-sealing surface and one of the first and the second, opposite groove flanks, wherein, when inserted in the groove, the sealing ring lies at least in sealing fashion against the sealing surface of the at least one supporting ring and the groove base, and wherein, in the installed state, the sealing ring is compressed into the groove, deforming its cross-section so that the sealing ring lies in sealing fashion against the sealing surface of the supporting ring and the groove base and against the groove flank that is arranged opposite the at least one supporting ring, forming a continuous sealing surface extending over the supporting ring-sealing surface, the groove base and the groove flank being opposite to the supporting ring.
