Abstract

In an axial flow turbine having a casing disposed about a rotor, a liner also disposed about the rotor and in a radially spaced relationship with the casing, such that the spaced relationship defines an annular opening, and an annular row of stationary blades positioned within the annular opening, apparatus for maintaining the efficiency of said turbine is shown to include a sealing mechanism, connected to the stationary blades, for preventing motive fluid applied to the annular opening from circumventing the stationary blades so that the efficiency of the turbine is maintained. The sealing mechanism includes a pair of sealing bars disposed between the stationary blades, the casing and the liner.
