Damper to control fluid flow and associated methods

A damper for controlling fluid flow includes a main body, a stator and a rotor. The stator may be carried by the main body and include at least one blade having a predetermined shape. The rotor may be moveably connected to the stator and carried by the main body. The rotor may include at least one b...

Beschreibung
Zusammenfassung:	A damper for controlling fluid flow includes a main body, a stator and a rotor. The stator may be carried by the main body and include at least one blade having a predetermined shape. The rotor may be moveably connected to the stator and carried by the main body. The rotor may include at least one blade having a predetermined shape and may be moveable between an opened position and a closed position. The predetermined shape of the at least one stator blade and the at least one rotor blade may form a converging-diverging nozzle, and the stator and the rotor may be carried by the main body so that fluid flows through the main body substantially perpendicular thereto. The opened position may be defined as the at least one stator blade being aligned with the at least one rotor blade, and the closed position may be defined as the at least one stator blade being offset from the at least one rotor blade.
