Seal between two elements having separate thermal expansion coefficients

摘要

The invention relates to a seal (10) provided between two elements (4', 6) having separate thermal expansion coefficients, wherein said seal includes: a first and second metal contact portion (16a, 16b) spaced from each other in an axial stacking direction (8) orthogonal to a radial direction (20); sealed-linking means (14) provided between the portions (16a, 16b) and enabling a relative movement between the latter in the radial direction; and a first and second sliding part (24a, 24b) respectively coupled in translation to the portions (16a, 16b) in the radial direction, and stacked in such a way as to slide relative to each other in the radial direction.
