Abstract
A sealing device is provided, specifically between engine spaces which fluidically are acted upon by a different pressure, particularly for turbo-engines, such as gas turbo-engines. The sealing device includes at least one brush sealing device non-rotatably anchored at the stator side, the free bristle ends of this brush sealing device being guided in the direction toward an engine rotor. In this case, the brush sealing device is to be constructed as a radial sliding ring sealing device. The free ends of the bristles, while forming a secondary sealing, are guided in a circumferential groove of a sliding ring which is separated at least at one circumferential point, and which, on the side facing away from the bristles, forms a self-centering primary sealing at the engine rotor.
