20140255154 | REACTION-TYPE TURBINE - A reaction-type turbine according to the present invention is configured in that a portion of a rotary shaft module which penetrates through a side with an inlet portion of a housing has a diameter larger than the diameters of other portions. Thus, the pressurized area in which a working fluid applies pressure to a rotary shaft in the direction opposite to the working fluid flow direction increases, thus increasing force in the direction opposite to the working fluid flow direction. As a result, axial direction force applied to the rotary shaft in the working fluid flow direction may be reduced. Therefore, the reaction-type turbine of the present invention has the advantages of eliminating the necessity of installing a separate thrust bearing for supporting axial force in the working fluid flow direction. | 09-11-2014 |

In addition, a cross section of each of the first and second flow paths can be formed into a semicircular shape thus yielding a circular shape for the inner flow path, which is formed by combining the first and second flow paths, thereby effectively enhancing the performance of a turbine by minimizing pressure loss of a working fluid that passes through the inner flow path. | 05-21-2015 |
