摘要： A wind turbine generator (100), or other energy extraction device, has a hydraulic circuit comprising a hydraulic pump (129) driven by a rotating shaft (125) and a hydraulic motor (131) driving an electricity generator (157), or other load. A high pressure manifold (133) extending between the pump and motor is in communication with an accumulator (145, 147, 149). A controller receives a control signal and regulates the displacement of working fluid by the hydraulic pump and the hydraulic motor relative to each other. Thus, power input through the rotating shaft and output to the load can be decoupled for at least a period of time and the energy output of energy extraction device can be varied, for example to smooth the total power output to an electricity grid (101), without compromising power input. A group of energy extraction devices can be controlled in concert to maximise power input while providing smooth power output. Individual electricity generators in different energy extraction devices can be switched on and off in concert to provide smooth power output while benefiting from the reduced energy losses that can be obtained by switching off electricity generators where possible.

摘要： A fluid working machine has at least one working chamber of cyclically varying volume and low and high pressure valves to regulate the flow of working fluid into and out of the working chamber, from low and high pressure manifolds. The low and high pressure valves are actuated by electronically controlled valve actuation means which, when actuated, applies forces to the low and high pressure valve members to open and/or close the respective valves. The low and high pressure valve members are independently moveable and, although the low pressure valve member typically begins to move quickly in response to a shared valve control signal, the high pressure valve member typically moves only after a change in the pressure within the working chamber. The electronically controlled valve actuation means may be a shared electronically controlled valve actuator, such as a solenoid within a magnetic circuit which directs magnetic flux through both low pressure and high pressure valve armatures which are connected to the respective valve members.

摘要： A hydraulic pump comprises (1) an outward ring (24), including demountable blocks (30) comprising piston cylinders (32), and an inward ring (21), comprising a ring cam (23), coupled through a drive shaft (8) to the blades of a turbine (4). To enable maintenance, the outward ring is decoupled from a torque limiting device (16, 17) and rotated relative to the inward ring. Demountable blocks are then removed from the outward ring using a crane (61) including a line (62) extending from above the centre of mass of the demountable block and including a resilient portion (66) so that although the crane supplies the majority of the force required to remove the demountable block, an operator provides some force, enabling the process to be controlled. The method is suitable for maintaining large hydraulic pumps in wind turbine nacelles (2).

摘要： A large hydraulic radial piston pump (1) suitable to be driven by the turbine (4)of a wind turbine generator has a circular cover (40) formed from at least three cover segments (42). Underneath the cover segments a seal (46) in the form of a vulcanised rubber band extends around the entire periphery of the pump. Thus, the cover can be readily removed within the difficult to access location of a wind turbine nacelle, but a reliable seal can still be formed. An air pocket (60) outside the seal, or within the seal, facilitates pulsatile flow into the cylinders of the pump during operation.

摘要： An annular valve (1) has an annular valve member (4) and inner and outer annular valve seats (12, 14). Inner and outer sealing ridges (8, 10) are formed either on the annular valve member or on the valve seats. The inner sealing ridges are more resistant to plastic deformation than the outer sealing ridges. They may be thicker, or made from a harder material. Thus, the annular valve better resists damage arising from greater plastic deformation of the inner sealing ridge than the outer sealing ridge due to greater forces (Fi, Fo) acting on the inner sealing ridge than the outer sealing ridge in use.

摘要： Disclosed is a cylinder assembly (1) for a fluid-working machine, the assembly comprising a body (2) having a first end (3) and a second end (4) and comprising a cylinder (5), a poppet valve seat (9) and a face-sealing annular valve seat 7). The cylinder is open to the first end and configured to receive a reciprocating piston (210) and the poppet and annular valve seats extend around an axis through the cylinder. An annular valve including the annular valve seat and an annular valve member extends around the cylinder. Thus, the cylinder assembly is compact. Advantageously, the body is a continuous unitary structure which comprises all of the parts of the body which must be made of, or coated with, a hardened material. Thus the body is stronger and may be constructed with less material than has previously been possible. Additionally, the arrangement of the cylinder body facilitates manufacture, assembly and maintenance of a cylinder assembly and its insertion into the body of a fluid working machine. Further structural features of the cylinder assembly and a fluid working machine comprising one or more cylinder assemblies, are disclosed, which reduce the forces received by the cylinder body (and associated apparatus) in use, enabling the construction of smaller and lighter apparatus.
