  • Patent number: 9506424
    Abstract: A device and a method for bleeding compressor air in an engine includes at least one actuator and at least one closing element linked to the actuator for closing or partially closing a bypass duct via which compressor air can be bled off. It is provided here that the closing element is designed to be successively moved into the bypass duct, with the airflow passing through the bypass duct being settable by the position of the closing element. Furthermore, an air guiding device linked to the closing element is provided and has air guiding surfaces which adjoin the closing element downstream, the spatial alignment of the air guiding surfaces being dependent on the position of the closing element.
