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： The invention to a valve unit (1) for a synthetically commutated fluid working machine (51), comprising a valve body (19,57), a movably arranged valve unit (3) and a separate fluid flow influencing unit (13, 25, 31, 35, 46, 56). The fluid flow influencing unit (13, 25, 31, 35, 46, 56) comprises a fluid flow influencing means part (18) and an attachment means part (28, 34, 38) for mechanical connection with the valve body (19). The attachment means part (28, 34, 38) and the fluid flow influencing unit (18) are connected to each other by a connection means part (27, 30, 33, 40, 47). The circumferential extent of the attachment means part (28, 34, 38) is larger as compared to the circumferential extent of the connection means part (27, 30, 33, 40, 47).

摘要： A fluid working machine of the type comprising working chambers 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, in which the valves are electronically controlled on each cycle of working chamber volume, by way of valve actuation signals, to determine the net displacement of working chambers. Additional valve actuator signals are generated in response to determination that a valve or working chamber has been inactive to adapt the valve to operate more reliably when subsequently actuated, but without significantly altering the net displacement of working chambers.

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.
