Abstract

L’invention se rapporte à un système de propulsion (1, 100) d’un véhicule comprenant une ligne d’admission d’air (2, 102) et un moteur thermique (3, 3), ladite ligne (2, 102) comprenant un compresseur basse pression (6, 106), un compresseur haute pression (8, 108) et une valve compresseur (11, 111). Selon l’invention, le système de propulsion comprend un premier canal (130) reliant le compresseur basse pression (106) à la valve (111), et un deuxième canal (109) reliant ledit premier canal (130) au compresseur haute pression (108), le premier canal (130) et le deuxième canal (109) formant un coude, de sorte que l’air passant dans le deuxième canal (109) pour alimenter le compresseur haute pression (108) se retrouve à contre flux de l’air passant par le premier canal (130) lorsque la valve (111) est dans la position de fermeture. Figure à publier : Figure 2The invention relates to a propulsion system (1, 100) of a vehicle comprising an air intake line (2, 102) and a heat engine (3, 3), said line (2, 102) comprising a low pressure compressor (6, 106), a high pressure compressor (8, 108) and a compressor valve (11, 111). According to the invention, the propulsion system comprises a first channel (130) connecting the low pressure compressor (106) to the valve (111), and a second channel (109) connecting said first channel (130) to the high pressure compressor ( 108), the first channel (130) and the second channel (109) forming an elbow, so that the air passing through the second channel (109) to supply the high pressure compressor (108) is found against the flow of the air passing through the first channel (130) when the valve (111) is in the closed position. Figure to be published: Figure 2
