Abstract

L'addition concerne des perfectionnements au procédé et dispositif d'aménagement de l'écoulement des gaz d'échappement décrits au brevet principaL Selon l'addition, la sortie du collecteur d'échappement est reliée à l'entrée d'une turbine de suralimentation au moyen d'une volute 51 coiffant la roue 52 de la turbine, la section d'écoulement des gaz dans cette volute diminuant progressivement de façon sensiblement linéaire d'une extrémité à l'autre de la volute. L'addition concerne notamment les collecteurs d'échappement des moteurs à combustion interné suralimentés.
