<p>An air generation unit (10) includes first and second air cycle machines (ACMs) (16, 18), each having first and second turbines (24, 26). A manifold (48) is arranged between the first and second ACMs (16, 18) and is in fluid communication with each of the first and second turbines (24, 26) of the first and second ACMs (16, 18). A condenser (44) is arranged between the ACMs (16, 18) and is in fluid communication with the manifold (48). First and second valves (102, 104) are disposed within the manifold (48) and control flow of air between the turbines (24, 26) and the condenser (44). An actuator assembly (108) is connected to the valves (102, 104) for moving the valves (102, 104) between a plurality of positions. The valves (102, 104) selectively close off or prevent the flow of air from the turbines (24, 26) of one of the ACMs (16, 18) in the event that the ACM (16, 18) is not needed or malfunctions. <IMAGE></p> |
