Abstract

Dispositif de régulation de la pression d'admission d'un moteur à combustion interne suralimenté par les gaz d'échappement pourvu d'un compresseur à gaz d'echappement constitué par un surcompresseur et une turbine à gaz d'échappement et comprenant une soupape de régulation répondant à la pression d'admission du surcompresseur disposée dans la conduite collectrice des gaz d'échappement du moteur, cette soupape commandant une conduite additionnelle du gaz d'échappement par laquelle les gaz d'échappement déchargés à l'avant de la turbine à gaz d'échappement sont ramenés à la partie de la conduite collectrice de gaz d'échappement du moteur située à l'arrière de la turbine à gaz d'échappement. Les gaz d'échappement qui sont déchargés à l'extérieur à l'avant de la turbine à gaz d'échappement 11 sont envoyés dans un éjecteur 18 disposé dans la partie 12 de la conduite collectrice de gaz d'échappement située à l'arrière de la turbine à gaz d'échappement 11.Device for regulating the intake pressure of an internal combustion engine supercharged by the exhaust gases provided with an exhaust gas compressor consisting of a supercharger and an exhaust gas turbine and comprising a relief valve regulation responding to the inlet pressure of the supercharger arranged in the collecting duct of the engine exhaust gases, this valve controlling an additional exhaust gas line through which the exhaust gases discharged at the front of the turbine to exhaust gases are returned to the part of the engine exhaust gas collection line located at the rear of the exhaust gas turbine. The exhaust gases which are discharged to the outside at the front of the exhaust gas turbine 11 are sent to an ejector 18 arranged in the part 12 of the exhaust gas collecting pipe located at the rear of the exhaust gas turbine 11.
