<p>The invention refers to a hydrodynamic transducer which includes a toroid enclosure (35) which holds the pumping rotor (31) integrated within a driving shaft (37), a turbine rotor (32, 32', 32'') linked to the driven shaft (36), an assembly of control guiding shoulder blades (33) which are regarding to the flow direction of the operating media distributed between the turbine rotor (32, 32', 32'') and the pumping rotor (31) as well as a set of fixed guiding shoulder blades (34) which are considering the medium flow direction distributed between the pumping rotor (31) and the turbine rotor (32, 32', 32''). Regarding this the pumping rotor (31) and the turbine rotor (32, 32', 32'') are designed so that the inlet diameter (D321) of the turbine rotor (32, 32', 32'') is smaller from the outlet diameter (d312) of the pumping rotor (31) and that the pumping rotor (32, 32', 32'') is adapted for pumping the operating media in the direction radially towards the rotation axis (38). Such a hydrodynamic torque transducer enables the reaching of the maximum efficiency in the range of the revolutions ratio which is smaller or equal to nT/nP being smaller or equal to 4, while nP represents the rotating speed of the pumping rotor (31) on the driving shaft (37) and nT the rotating speed of the turbine rotor (32, 32', 32'') on the driven shaft (36). The operation area at a high efficiency rate is actually far wider compared to the one on currently known devices, while apart from than the torque dynamics on the turbine side is more favourable.</p> |
