Abstract

Dans ce moteur, la chemise humide 1 présente des bossages creux formant des conduits de transfert et qui, au montage, passent dans des creux ménagés entre des nervures d'appui qui servent à centrer le bord supérieur de la chemise Les joints sont fermés en haut et en bas par des garnitures 8 et 9. La lumière d'échappement 13 est raccordée au conduit 14 par un manchon à bride 15 appuyé sur la chemise avec interposition d'un joint plat en amiante 17 et sa bride est appuyée sur le bloc-moteur 2 à travers une bague torique 18.
