Abstract
A stator device for a continuous-flow machine with guide vanes circumferentially distributed on a housing. The guide vanes are respectively embodied with a blade leaf and at least one platform. The platforms form a surface of an annular channel through which working fluid flows. A flow area is provided via which, during operation of the stator device, a working fluid flows on a side of the platform that is facing away from the annular channel from a pressure side of the blade leaf to a suction side of the blade leaf at least in certain areas in the radial direction of the stator device. At least one suction appliance is provided which adjoins the flow area and is formed by a recess, and via which working fluid can be conducted out of the flow area during operation of the stator device.
