Abstract

Dans le dispositif 1 selon l'invention, il est prévu qu'une première couche de support 3 soit reliée de manière fixe à une pièce 2 à isoler, notamment un élément de moteur à combustion interne, véhiculant de l'huile, et qu'une couche d'isolation 4, présente un grand nombre d'éléments d'isolation individuels, notamment des éléments de fibres 5 ou de nids d'abeille, qui sont reliés et/ou articulés individuellement à la couche de support 3, un matelas d'air 6 étant formé entre les éléments d'isolation individuels, à l'intérieur de la couche d'isolation et/ou entre la couche de support et la couche d'isolation, et ce matelas d'air pouvant être modifié par le déplacement de réglage de plusieurs éléments d'isolation 5, de l'ensemble de la couche d'isolation 4 et/ou de la couche de support 3.
