  • Patent number: 7762764
    Abstract: A turbomachine, especially a steam turbine (10), has an inner casing (15a) and an outer casing (17a), which concentrically encompass a rotor which is rotatable around a machine axis, wherein the outer casing (17a) encloses the inner casing (15a) with a radial space (d), and at least the inner casing (15a) is divided in a parting plane (22) into two casing halves (15a) which can be releasably interconnected by flanges (18) which are attached to the casing halves (15a), and wherein the casing halves (15a) of the inner casing (15a) have a thickening (20) in the region between the flanges (18). A change of the interspace between the casings is largely avoided by the outer casing (17a), in the region of the thickening (20) of the inner casing (15a), being adapted to the thickening (20) so that the radial space (d) between inner casing (15a) and outer casing (17a) outside the flanges (18, 19) is largely constant over the casing circumference.
