Abstract (en)
One embodiment of the present invention is a system for controlling flow through a rotor (10). The system includes an inlet port (24) in the rotor (10) and an outlet port (26) in the rotor (10). The outlet port (26) is in fluid communication with the inlet port (24). A fixed orifice (40) is disposed in at least one of the inlet or outlet ports (24,26). A variable orifice (28) is disposed in at least one of the inlet (24) or outlet ports (26) in a separate location from the fixed orifice (40).
