A centrifugal machine having a variable diffuser that includes a radially disposed fixed wall and an opposed movable wall defining the diffuser passage. Guideways are formed in the movable wall in which a series of diffuser vanes are slidably mounted. A spring biased retainer loosely holds each of the vanes in an associated guideway and urges the vanes into seating contact with the fixed wall so that each vane can adjust its position in assembly to accommodate for changes in diffuser alignment due to thermal growth or the like. |
