Abstract
A seal apparatus for a casing of a turbomachine. The seal apparatus may include an annular body having first and second annular body portions and an appendage. The second annular body portion may extend axially from the first annular body portion and may have an outer annular surface radially offset from an outer annular surface of the first annular body portion. The appendage may extend axially from the first annular body portion and may have an outer annular surface and an inner annular surface. The inner annular surface of the appendage and the outer annular surface of the second annular body portion may define an annular cavity therebetween, and at least a portion of the appendage may be configured to be displaced radially outward in order to maintain contact with first and second inner cylindrical surfaces of the casing during radial expansion of the casing.
