    • An impeller for a turbine includes an impeller body formed by alternately stacking and fixing two or more types of disk blades, a base plate, and a rotating shaft. A plurality of pressed vane sections projecting from one surface are formed on the base plate of each disk blade, and recessed spaces are formed in the pressed vane sections, respectively. The projecting rear sections of the pressed vane sections are affixed to the other surface of the base plate of the adjacent disk blade, and disposed in the recessed spaces of the pressed vane sections of the adjacent disk blade in the mutually crossing direction. A part of a working gas is moved in the recessed spaces, and moved forward in the rotating direction over the projecting rear sections.
    • 涡轮叶轮包括通过交替地堆叠和固定两种或更多种类型的盘片,基板和旋转轴而形成的叶轮体。 在每个盘片的基板上形成有从一个表面突出的多个按压叶片部分,并且在按压的叶片部分中分别形成有凹进的空间。 压缩叶片部分的突出的后部固定到相邻盘片的基板的另一个表面,并且在相互交叉的方向上设置在相邻盘片的压缩叶片部分的凹陷空间中。 工作气体的一部分在凹陷空间中移动,并且在旋转方向上在突出的后部上移动。
