ABSTRACT:
A thermal turbomachine such as an axial flow steam turbine of the center intake opposite flow type includes an intake duct surrounding the rotor and which is delimited by a portion of the internal surface of an inner housing surrounding the rotor and by the juxtaposed surfaces of two rotationally symmetrical shells. In order to permit the shells to expand substantially unhindered in relation to the inner housing as a result of imposed thermal stresses and still provide a gastight seal between an internal surface portion of the inner housing and the peripheral portions of the shells the latter are pressed into a slidable sealing engagement with the former rather than rigidly attached to each other. According to one embodiment, the slidable sealing engagement between the parts is established by means of a groove provided on one part into which the other part is fitted. In another embodiment, the peripheral portions of the shell are pre-stressed so as to press against and slidably engage the internal surface of the inner shell.
