Claim Text:
1. A device for bleeding compressor air from a compressor of an engine, comprising: at least one actuator, at least one closing element linked to the at least one actuator for closing or partially closing a bleed duct via which compressor air is bled off, wherein the at least one closing element is progressively movable into the bleed duct, using the at least one actuator such that a flow of bled compressor air passing through the bleed duct is settable by a position of the at least one closing element in the bleed duct, and an air guiding device linked to the at least one closing element, the air guiding device positioned along a length of the bleed duct and including air guiding surfaces which adjoin a downstream end of the at least one closing element, with an orientation of the air guiding device with respect to the at least one closing element being dependent on the position of the at least one closing element in the bleed duct; the air guiding device being connected at a first connection to the at least one closing element to be movable into the bleed duct with the at least one closing element, and, downstream of the first connection, the air guiding device being connected at a second connection with a casing of the engine; wherein the air guiding device includes a plurality of flaps, and the first connection includes each of the plurality of flaps being connected to the at least one closing element by a respective pivot joint to be movable relative to the at least one closing element, the plurality of flaps forming at least a portion of the air guiding surfaces; wherein an inclination angle of each flap is dependent on the position of the at least one closing element; wherein the second connection includes each of the plurality of flaps being connected to the casing by a respective further pivot joint; wherein each respective pivot joint is positioned on a side of the at least one closing element facing away from the bleed duct and each respective further pivot joint is positioned on a side of the plurality of flaps facing away from the bleed duct.
