摘要： Disclosed is a steam turbine comprising an exterior housing and an interior housing. The exterior housing and the interior housing are provided with a fresh steam supply duct. A rotor that encompasses several impeller blades and a thrust-compensating piston is rotably mounted within the interior housing. Said interior housing is equipped with several guide blades that are disposed such that a flow duct comprising several blade stages, each of which comprises a series of impeller blades and a series of guide blades, is formed along a specific direction of flow. The interior housing is further equipped with a recirculation duct which is embodied as a pipe that communicates between a space located between the interior housing and the exterior housing and the flow duct downstream of a blade stage. The interior housing is additionally equipped with a supply duct that is configured as a pipe which communicates between the space located between the interior housing and the exterior housing and an antechamber of the thrust-compensating piston located between the thrust-compensating piston of the rotor and of the interior housing.

摘要： A tubular housing for a turbomachine is provided. The tubular housing includes two half-tube shells which, lying against one another in two connecting regions overlap partially in each case in the tangential direction of the tubular housing. In order to specify a particularly reliable and permanent connection of the two half-tube shells which additionally develop a particularly satisfactory sealing action, it is proposed that, in order to interlock the half-tube shells in the tangential direction, in relation to the tube axis of the housing, at least one eccentric pin is provided in one or both connecting regions.
