Miroslav SEDLACEK Stanislav HOSTIN: Rolling Fluid Machine

1.  The Invention



Rolling Fluid Machine
The problem the inventor(s) wanted to solve

We searched for possibilities how to effectively use very small water sources that are still not used for energetic use in the nature 


It is turbine where rotor has the shape similar to half sphere. If water (or other fluid) starts to flow through the turbine, rotor will generate in mouth nozzle and shaft start to move, too.

See the enclosed “Basic turbine scheme”
Fields of application

Turbine is usable mostly for producing energy from very small water sources


Main advantage is simplicity and efficiency of this engine using side-values. For instance: flow volume (Q) = 3-15 liters of water per second, head (H) = 3 -15 meters. It can also work at extremely low heads, about 1 m (H = 0,5 – 1,5 m) at flow volume decades or hundreds liters (Q = 40 – 400 l/sec).
