20110209783VALVE ASSEMBLIES - An electronically actuatable valve assembly having a primary face seating valve, including a primary valve member, and a secondary valve, including a secondary valve member. The secondary valve opens before the primary valve to equilibrate pressure across the primary valve member and thereby facilitate opening of the primary valve member. The secondary valve is coupled to an armature which moves from a first position to a second position, in use, attracted by an electromagnet. The coupling between the armature and the secondary valve is configured to enable the armature to begin to move from the first position without movement of the secondary valve. The armature has therefore moved from the first position, closer to the electromagnet, when the secondary valve is opened by way of the forces exerted through the coupling between the armature and the secondary valve member, and so a greater force can be exerted to open the secondary valve than would be the case if the secondary valve member was fixedly coupled to the armature.09-01-2011
20110209784VALVE ASSEMBLIES - An electronically actuatable valve assembly including a valve member comprising a ferromagnetic member, and a magnetic circuit adapted to direct magnetic flux through the ferromagnetic member when the valve member is spaced apart from its valve seat, to hold the primary valve open.09-01-2011

20110315003VALVE ASSEMBLY - A valve assembly for regulating the flow of fluid between a working chamber of a fluid-working machine and a fluid manifold. The valve assembly comprising a valve body comprising a valve seat, a fluid passage extending through the valve body, and a travelling member comprising a valve member and operable between an open position in which the valve member is spaced apart from the valve seat and fluid can flow through the fluid passage and a closed position in which the valve member is in sealing contact with the valve seat preventing fluid from flowing through the fluid passage. The valve assembly further defines a fluid flow path passing in a first fluid flow mode, between the valve member and the valve seat, and into the fluid passage. The valve assembly is characterised by a barrier upstream of the valve member, to the barrier reduces one or more forces which would otherwise act on the valve member as a result of the flow of fluid to urge the valve member towards the valve seat. Thus, one or more forces which would otherwise act on the valve member to urge the valve member to the closed position due to the flow of fluid past the valve member in the first fluid flow mode are reduced or removed. There is also disclosed a valve assembly in which fluid flowing along the said fluid flow path is incident on the downstream surface of the valve member at an angle of at least 80° to the direction in which the valve member is operable to travel between the open position and the closed position.12-29-2011
20110315004VALVE ASSEMBLY - A valve assembly suitable for regulating the flow of fluid between a working chamber of a fluid-working machine and a fluid manifold. The valve assembly comprises a valve body comprising a valve seat, a fluid passage extending through the valve body, and a travelling member comprising a valve member, which valve member is operable between an open position in which the valve member is spaced apart from the valve seat and fluid can flow through the fluid passage and a closed position in which the valve member is in sealing contact with the valve seat preventing fluid from flowing through the fluid passage. The valve assembly defining a fluid flow path passing, in a first fluid flow mode, between the valve member and the valve seat, and into the fluid passage. The valve assembly is characterised by defining a fluid flow path including a constricted flow region and further comprising a reduced pressure chamber in communication with both a first surface of the travelling member and the constricted flow region, arranged to exert a force on the travelling member by way of a pressure reduction in the reduced pressure chamber when fluid is flowing along the fluid flow path, through the constricted flow region, which force acts to resist closure of the valve. Thus, a force is generated which opposes forces acting on the valve member due to the flow of fluid past the valve member.12-29-2011
20110315251ELECTRONICALLY CONTROLLED VALVES - An electronically controlled valve includes a travelling member with a sealing member and operable between a closed position in which the sealing member forms a seal with a valve seat, and an open position. The valve further has a decelerating mechanism operable to slow the movement of the armature during closure of the valve. The sealing member and armature are decoupled and thereby moveable relative to each other such that the armature can continue to move and decelerate due to the action of the damping mechanism after the sealing member has impacted the valve seat. 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.12-29-2011
20120000554ELECTRONICALLY CONTROLLED VALVES - An electronically controlled valve for regulating the supply of fluid between a working chamber of a fluid working machine and a manifold, which valve includes a pilot valve and a pilot valve elastic member charged in use by the movement of the armature towards the electromagnet during closure of the valve to provide a return force urging the pilot valve sealing member away from the pilot valve seat. The valve is especially useful as the low pressure valve of a fluid working motor.01-05-2012
20120042771ELECTRONICALLY CONTROLLED VALVE - An electronically controlled valve includes a valve member moveable between a first position and a second position. 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.02-23-2012

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.03-08-2012
