As described in detail above, water (shown in light blue) is sucked in through inlet E into the area of the turbine-inlet designated TE. This water then flows both upwards and outwards, flowing inside saw-tooth-like turbine-grooves positioned close to the conical wall of the outer housing KW. Approaching the exit point, the water is deflected into a groove which runs all around the turbine cone, so that at outlet A, in Figure 07.05.13 a steady, flat jet of water is ejected outwards. This water flies into the air-filled area shown shaded light yellow, and falls under gravity as indicated by the blue points. The level of the water in that backflow area R, is only a few centimetres below the level of outlet A, so water is lifted against gravity through only a small height.
The water flow exiting the turbine does so at a relatively steep angle, and that flow moves relatively slowly relative to the already spinning turbine cone. When flowing downwards, the water should generate some faster rotational movement, guided by correctly curved fins, marked here as 'backflow-stator' RS (shown in dark blue). The conical wall is attached to the housing by these cross-beams.
In the lower diagram, at the backflow-area, an 'inlet-stator' ES (shown shaded in dark blue) is marked and through these fins water is directed again into the turbine intake area. As explained earlier, suction, generated by centrifugal forces, pulls the water upwards. That water does not flow straight upwards but rotates as it moves upwards and so rotational acceleration forces are generated.
The inlet area is divided by six appropriately curved fins, as indicated in the plan-view schematic diagram at the bottom of the Figure. These conduit sections could have vertical dividers if so desired. The shape (or any equivalent design of conduit) produces the necessary rotation and angle of water flow needed at the turbine inlet.
