    • 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.
    • 根据本发明的反应型涡轮机的结构是,通过具有壳体的入口部分的侧面的旋转轴组件的一部分的直径大于其它部分的直径。 因此,工作流体在与工作流体流动方向相反的方向上对旋转轴施加压力的加压区域增加,从而增加与工作流体流动方向相反的方向的力。 结果,可以减小在工作流体流动方向上施加到旋转轴的轴向力。 因此,本发明的反应式涡轮机的优点是消除了在工作流体流动方向上安装用于支撑轴向力的单独的止推轴承的必要性。
