Arrangement having a seal, seal, and turbocompressor

An arrangement, comprising:

• an annular seal which extends about a machine axis;
• a vessel for sealing an L-shaped gap which extends along a circumferential direction between a vessel main body and a cover, a radial section of the gap extending in the radial direction and circumferential direction and an axial section extending in the axial direction and circumferential direction;
• and
• a seal chamber provided in the region where the radial section and the axial section meet, wherein the seal chamber is widened radially and axially with respect to the adjacent gap sections,
• wherein the seal is arranged in the seal chamber, a higher pressure prevailing in the radial section than in the axial section, which pressure difference is sealed by means of the seal,
• wherein the seal includes a supporting ring which is arranged radially on the inside and is made from a first material,
• wherein a jacket element which is made from a second material which is more readily deformable than the first material adjoins the supporting ring radially on the outside,
• wherein the jacket element includes a circumferential recess radially on the outside, in such a way that two axial bounding walls of the recess of the jacket element are deformed under pressure loading from the direction of the radial section in such a way that the jacket element is widened axially, and
• wherein the seal is mirror-symmetrical with regard to a radial plane.
