| 摘要 |
The invention proposes a sealing device intended to be compressed between the joint planes (14, 16) of two components (10, 12) to be fixed to each other in leaktight fashion, of the type including a sealing gasket including an active sealing part made of a material with a low elastic modulus in compression intended to provide sealing between the two components when its thickness (E) in a compressed position lies between a maximum tightening thickness (Emax) and a minimum tightening thickness (Emin), characterised in that it includes at least a second active part (202) of the same design adjacent to the first active sealing part (201), and in that the maximum (Emax, Emax2) and minimum (Emin, Emin2) tightening thicknesses of the two active parts (201, 202) are such that: Emin2<Emin1</=Emax2<Emax1. Application particularly to sealing between a motor vehicle inlet manifold and cylinder head. <IMAGE>
