ABSTRACT:
A housing assembly for a turbine engine has a housing which is adapted to cooperate with an adjacent valve ring assembly. The housing has a plurality of passages for working medium gases which extend radially through the housing and are circumferentially spaced in the housing. The valve ring modulates the flow through the passages. A plurality of flanges extend axially and circumferentially from the housing. Each flange has a track opening which receives a liner and a roller assembly having a bearing surface. The roller assembly in combination with the liner guides the valve ring assembly. The liner and the housing have different physical characteristics, such as a different rate of thermal expansion and different spring rate characteristics which accommodate differences in thermal growth between the liner and the housing.
