Abstract
A shroud assembly is pneumatically operated to adjust the clearance between the shroud segments and the tips of the rotor blades of an associated rotor. The assembly comprises a casing to which is secured a wall member which defines a chamber whose pressure may be varied by a valve. The wall member carries shroud segments some of which define the static wall with which the rotor blades co-operate. In order to allow proper movement of the shroud segments the support means which carry the segments from the wall are arranged to be small in axial extent compared with that of the wall.
