Abstract (en)
[origin: EP0863296A2] The guide blade has a cavity (18) under low pressure, e.g. connected directly to the condenser, inside it, and has an aperture (3) for fluid suction in the region of its rear edge. This aperture has a porous cover (7) with capillaries which are filled with the fluid being sucked during operation. The porous cover is anchored in the blade by a mechanical fixing element (20) in the form of a spring-loaded quick lock. It consists of a bush (21) which locates the cover in the blade aperture. The cylindrical part (24) projects into the blade cavity. A movable mandrel (25) in the bush is loaded by a spring (26) and has a cap (28) on the inner wall of the blade.
