Abstract Translated from French 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. The addition relates to improvements to the method and device for adjusting the flow of exhaust gases described in the main patent. According to the addition, the outlet of the exhaust manifold is connected to the inlet of a supercharging turbine by means of a volute 51 covering the wheel 52 of the turbine, the gas flow section in this volute gradually decreasing in a substantially linear fashion from one end of the volute to the other. The addition relates in particular to the exhaust manifolds of supercharged internal combustion engines.
