摘要： Disclosed is a method of detecting a fault in a fluid-working machine comprising a plurality of working chambers of cyclically varying volume, each said working chamber operable to displace a volume of working fluid which is selectable for each cycle of working chamber volume to carry out a working function responsive to a received demand signal. An output parameter of the fluid working machine, which is responsive to the displacement of working fluid by one or more of the working chambers to carry out the working function, is measured. It is determined whether the measured output parameter fulfils at least one acceptable function criterion, taking into account the previously selected net displacement of working fluid by a working chamber during a cycle of working chamber volume to carry out the working function. By taking into account the previously selected net displacement of working fluid by a working chamber during a cycle of working chamber volume to carry out the working function, an unacceptable fault in a fluid-working machine may be detected if it causes one or more measured output parameter to respond in a way which would not be expected if the fluid working machine was functioning acceptably.

(5, 7) The segments have piston facing surfaces (15, 16)together defining a working surface of the fluid-working machine. The segments comprise a leading cooperating formation (46) which has a piston facing surface which forms part of the working surface, at a trailing end, and which is recessed from the working surface at a leading end, and a trailing cooperating formation (40) which has a piston facing surface which forms part of the working surface at a leading end, and which is recessed from the working surface at a trailing end.

摘要： A fluid working machine, operable to carry out a motoring cycle under at least some circumstances, comprises a controller (12) and a working chamber (2) of cyclically varying volume. The working chamber has a high pressure valve (18) associated therewith to control the connection of the working chamber to a high pressure manifold (20), and an electronically controllable primary low pressure valve (14) to control the connection of the working chamber to a low pressure manifold. The controller is operable to actively control at least the primary low pressure valve, in phased relationship to cycles of working chamber volume, to determine the net displacement of fluid by the working chamber on a cycle by cycle basis. The fluid working machine is adapted to release pressurised fluid from the working chamber prior to the opening of the primary low-pressure valve, during a motoring cycle. This facilitates the opening of the primary low pressure valve.

摘要： An electronically controlled valve includes a travelling member comprising a sealing member (12) and operable between a closed position in which the sealing member (12) forms a seal with a valve seat (4), and an open position. The valve further comprises a decelerating mechanism, such as a damping mechanism, operable to slow the movement of the armature (18) during closure of the valve. The sealing member (12) and armature (18) are decoupled and thereby moveable relative to each other such that the armature (18) can continue to move and decelerate due to the action of the damping mechanism after the sealing member (12) has impacted the valve seat (4). The peak deceleration force on the armature is thereby reduced, increasing the lifetime of the valve or the maximum rate at which it can be closed without damage.
摘要翻译：一种电子控制阀包括一个包括一个密封件（12）的行进件，并且在密封件（12）与阀座（4）形成密封件的关闭位置和打开位置之间可操作。阀还包括减速机构，例如阻尼机构，其可操作以在闭合阀门期间减慢电枢（18）的运动。密封构件（12）和电枢（18）被去耦合并且因此能够相对于彼此移动，使得电枢（18）可以在密封构件（12）被撞击之后由于阻尼机构的作用而继续移动和减速阀座（4）。因此，电枢上的峰值减速力减小，增加了阀门的寿命或者可以关闭阀门的最大速度，而不会受到损坏。

摘要： A fluid working machine comprises a controller (12) and a working chamber (2) of cyclically varying volume. The working, chamber has both an electronically controllable primary low pressure valve (14) and a secondary low pressure port (22) associated therewith, each of which is openable and closable in phased relation to cycles of working chamber volume to bring the working chamber into fluid communication with a low pressure manifold (16, 26). At least the primary low pressure valve is under the active control of the controller to enable the controller to determine the net displacement of fluid by the working chamber on a cycle by cycle basis. The primary low pressure valve and the secondary low pressure port are openable concurrently during a portion of at least some cycles of working chamber volume to enable fluid to flow into or out of the working chamber concurrently through both the primary low pressure valve and the secondary low pressure port. The primary low pressure valve may be closed under the active control of the controller a period of time after the secondary low pressure port closes.

摘要： An electronically controlled valve is suitable for regulating the flow of fluid between a fluid manifold and a working chamber of cyclically varying volume in a fluid-working machine having a rotating shaft. The valve includes a valve member moveable between a first position and a second position, wherein one of the first position and the second position is a position in which the valve is open and the other is a position in which the valve is closed. A valve member moving mechanism is operable to receive energy from a fluid-working machine crankshaft, or other rotating shaft, and to provide a valve member moving force to urge the valve member from the first position to the second position using the received energy. Thus, the energy used for movement of the valve against a pressure gradient is derived from the crankshaft. Energy received from the crankshaft can be stored and used subsequently to urge the valve member from the first position, allowing the valve to function despite timing differences between the availability of energy from the crankshaft and the requirement for energy to move the valve member.

摘要： A method of operating a hydraulic apparatus comprising a hydraulic circuit region and hydraulic machine which is controlled to displace pulses of fluid of known volume into or out of the hydraulic circuit region, generating pulses of pressure in the hydraulic circuit region and torque in the hydraulic machine shaft. The response of parts of the hydraulic apparatus to these pulses is measured and used to determine properties of the hydraulic apparatus. The response of the pressure in the hydraulic circuit region to pulses at different pressures can be used to measure the hydraulic stiffness of parts of the hydraulic circuit region. It is possible to detect faults and to make measurements useful in subsequent operation of the hydraulic apparatus.
