ABSTRACT:
A single stage energized fluid-flywheel comprises two concentric housings defining a main circulation chamber and an annular recirculation chamber surrounding the main circulation chamber. An axially extending shaft is rotatably mounted in the outer housing and has a series of blades mounted thereon. Upon rotation of the shaft, fluid is drawn by the blades into the inlet end of the main circulation chamber. The fluid is propelled from one series of blades to the next until it is discharged from the outlet end. The fluid is then redirected around the inner housing and recirculated through the recirculation chamber. The fluid, being constantly recirculated within the device will increase in speed or maintain the existing speed with relatively minimal force being applied to rotate the axially extending shaft. Toroidal shaped flow deflectors at opposing ends of the fluid flywheel facilitate smooth transition of fluid from the main circulation chamber to the recirculation chamber and vice versa.
