AIR INTAKE DEVICE WITH A VARIABLE-LENGTH INTAKE DUCT AND A SEPARATE CENTERING DEVICE

The invention relate to an air intake device with a variable-length intake duct, comprising: a base duct component with a base duct, configured for the passage of intake air through the base duct component; a supplementation duct component with a supplementation duct, configured for the passage of intake air through the supplementation duct component; a guidance device which guides the supplementation duct component and the base duct component to relatively move between a first operating position and a second operating position, wherein in the first operating position the base duct and the supplementation duct mutually leans against each other to form a continuous duct section, and in the second operating position, the supplementation duct is arranged at a distance from the base duct; and a first centering arrangement which, when the duct component is close to the first operating position, is configured to reduce the radial distance between the end section of the base duct facing the supplementation duct comp
