Abstract: The invention refers to a rotary flow machine having a rotor unit, rotating about a rotational axis, around which in at least one partial axial area a stationary inner housing (IH) is provided at a radial distance. The stationary inner housing (IH) can be divided up along the rotational axis in an upper and a lower inner housing half which adjoin each other along a horizontal split plane. The inner housing (IH) is surrounded in at least one axial section by an outer housing (OH) which can be divided up along the rotational axis in one upper and one lower outer housing half. Further a method for disassembling of a rotary flow machine is disclosed. The lower inner housing half provides support means which support the inner lower housing half on the lower outer housing half. The support means are detachably mounted at the lower inner housing half at least at two opposite support positions (P1, P2) relative to the rotational axis along the split plane.

Abstract translation: 本发明涉及一种具有转子单元的旋转流动机械，该转子单元围绕旋转轴线旋转，在至少一个部分轴向区域内以径向距离设置固定内壳体（IH）。 固定的内壳体（IH）可以沿着旋转轴线在沿着水平分割平面彼此相邻的上部和下部内壳体半部中分开。 内壳体（IH）通过外壳体（OH）在至少一个轴向截面中包围，外壳体（OH）可沿一个上外壳体和一个下外壳体半部中的旋转轴线分开。 另外公开了一种旋转流动机的拆卸方法。 下部内壳半部提供支撑装置，该支撑装置支撑下部外部壳体半部的内部下部壳体半部。 支撑装置至少在两个相对的支撑位置（P1，P2）处可拆卸地安装在下部内部壳体半部处，该支撑位置相对于旋转轴线沿分离平面。
