This patent describes a rotary machine of the type having an axially extending annular flow path for working medium gases, an axially extending flow path for cooling air and an array of circumferentially adjacent wall segments bounding the working medium flow path which includes a pair of circumferentially adjacent wall segments having facing sides which are free to move axially, radially and circumferentially with respect to each other and which are spaced circumferentially one from the other leaving a gap G therebetween which varies under operative conditions of the engine. An improved stator assembly is described wherein the improvement comprises: a coolable stator assembly having a pair of seal members which are radially spaced one from the other and which extend axially and circumferentially between the sides of the pair of wall segments and across the gap G, each seal member projecting circumferentially beyond and being free to move circumferentially with respect to one of the wall segments of the pair of adjacent wall segments. The seal members and the facing sides of the wall segments form a duct for the cooling air flow path, the duct being bounded by the seal members in the radially outward direction and the radially inward direction and bounded by the sides of the wall segments in either circumferential direction.
