    • A flow-propelled rotary knife system includes a housing, having an outlet end and walls defining a fluid passage, a rotatable blade holder, disposed at the outlet end and having a central aperture substantially aligned with the fluid passage, and at least one blade, extending diametrically across the central aperture of the blade holder. The blade holder is configured to rotate about a rotational axis passing through the central aperture, and the at least one blade has a twisted shape selected to rotationally propel the blade and the blade holder to rotate about the rotational axis when the blade is contacted by fluid flowing through the fluid passage and the central aperture in a flow direction, whereby objects propelled along the fluid flow path in the flow direction toward the outlet are helically cut by the rotating blade.
    • 流动推进的旋转刀系统包括壳体,其具有限定流体通道的出口端和壁,设置在出口端处并具有基本上与流体通道对准的中心孔的可旋转刀片保持器,以及至少一个叶片, 沿径向延伸穿过刀片保持器的中心孔。 叶片保持器构造成围绕穿过中心孔的旋转轴线旋转,并且当刀片与流体接触时,至少一个刀片具有被选择为旋转地推动刀片和刀片保持器围绕旋转轴线旋转的扭曲形状 在流动方向上流过流体通道和中心孔,由此沿着流动方向沿流体流动方向推进的物体朝向出口被旋转叶片螺旋切割。
