    • A variable displacement fluid working machine for use in applications where a large fluid working machine is required at an inaccessible location, for example, in the nacelle of a wind turbine tower. The machine includes an inward ring and an outward ring, one of the inward ring and the outward ring comprising a rotatable ring cam coupled to a drive shaft, the other comprising a plurality of radially extending piston cylinders circumferentially spaced around the respective ring. The outward ring comprising first and second axially spaced structural members and a plurality of demountable blocks demountably retainable therebetween, the demountable blocks comprising either piston cylinders or ring cam segments. The demountable blocks are removable radially to facilitate maintenance and repair and to facilitate radial access to the inward ring. Components of the inward ring may also be removed radially through the resulting gap. The demountable blocks also have a structural function, enabling the mass of the machine to be less than would otherwise be required.
    • 一种用于在不可接近的位置(例如在风力涡轮机塔架的机舱中)需要大型流体工作机的应用中的可变排量流体工作机。 机器包括向内的环和向外的环,其中一个向内环和向外的环包括联接到驱动轴的可旋转环形凸轮,另一个包括围绕相应环周向间隔开的多个径向延伸的活塞气缸。 所述向外环包括第一和第二轴向间隔开的结构构件和可拆卸地保持在其间的多个可拆卸块,所述可拆卸块包括活塞缸或环形凸轮段。 可拆卸块可径向移动,以便于维护和修理,并有助于径向进入内圈。 向内环的组件也可以通过所得到的间隙径向移除。 可拆卸块还具有结构功能,使得机器的质量能够小于否则需要。
