Abstract: A valve unit for regulating the flow of working fluid between a working chamber of a fluid working machine and both a first working fluid line and second working fluid line, the valve unit comprising: a first valve comprising a first valve member and one or more cooperating first valve seats, a second valve comprising a second valve member and one or more cooperating second valve seats, an actuator coupled to both the first and second valve members through which a force may be applied to urge the first valve member open or closed and to urge the second valve member open or closed, a coupling between the actuator and the first valve member, wherein the coupling between the actuator and the first valve member comprises a connector which extends at least partially through the second valve member.

Abstract: 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.
