A cooling air flow path (182) through an air cycle machine can include an inlet (184), at least one bearing (170) downstream from the inlet (184) and in fluidic connection with the inlet (184), an outlet downstream from the at least one bearing (170) and in fluidic connection with the at least one bearing, and an adjustment device (188) downstream from the at least one bearing (170) and in fluidic connection with the at least one bearing (170) and the outlet (186) with the adjustment device (188) configured to vary a flow of cooling air through the flow path by adjusting the cross-sectional area of the flow path. A corresponding method of cooling at least one bearing in an air cycle machine.
