Abstract

1340755 Gas turbine plant BROWN BOVERI & CO Ltd 16 Nov 1971 [18 Nov 1970] 53180/71 Heading F1G [Also in Division F2] A sealing ring for use between a cylindrical member and a surrounding tube in a turbomachine comprises segments 19, Fig. 4, having sealing means 28 on the internal surface and means, such as piston - and - cylinder assemblies 23, 24, for exerting a controlled pressure in a radially inward direction to press the ring into sealing engagement with the cylindrical member and in a radially outward direction to disengage the ring. As shown in Fig. 1, the turbomachine which consists of turbine 3, compressors 4, 5 & 6 and a casing 7, is inserted into a tube 1 embedded in concrete and a seal between the casing and tube is provided by several sealing rings 8 comprising the segments 19. The sealing strips 28 may be made of elastomers, plastics, metal or fabrics and clamped to the segments by members 27. Lip seals may be provided between adjacent segments in each ring. Hydraulic lines 31, 32 are provided to actuate the pistons 23.
