Abstract

L'invention concerne un système et un procédé pour la régulation du débit d'air dans un turbocompresseur. Le système peut comporter un dispositif de commande destiné à délivrer un fluide comprimé à un moteur (12, 112). Le dispositif peut comporter un logement (33), un compresseur (28, 170) en communication fluidique avec une source de fluide et le moteur (12, 112), le compresseur (28, 170) comportant une entrée (58) et une sortie et le compresseur (28, 170) étant positionné dans le logement (33). Le dispositif peut également comporter un régulateur de débit (52) en communication fluidique avec l'entrée (58) et la sortie du compresseur (28, 170), le régulateur de débit (52) délivrant sélectivement le fluide comprimé de la sortie du compresseur (28, 170) à l'entrée (58) du compresseur (28, 170) et délivrant le fluide au moteur (12, 112) en contournant le compresseur (28, 170).
