Abstract
The disclosure relates to a seal inserted between two elements having different coefficients of thermal expansion, the seal includes a first and a second metallic contact portion spaced along an axial stacking direction orthogonal with respect to a radial direction. Tight connection means between the first and second contact portions allow a relative movement between the first and second contact portions along the radial direction. A first and a second sliding part are respectively coupled in translation along the radial direction with the first and second contact portions and are stacked so as to be able to slide in relation to each other along the radial direction.
