摘要： An injection moulding system, water jet cutting machine or other industrial system has a synthetically controlled variable displacement fluid working machine. The working machine outputs hydraulic fluid to one or more fluid consumers 111, 112, such as rams or hydraulic motors, through hydraulically stiff fluid retaining volumes and receives hydraulic fluid back from one or more fluid consumers 111, 112 through the same or other said hydraulically stiff fluid retaining volumes. Individual piston cylinder assemblies can be allocated to different outputs. There may be no valve between the machine and the consumers. A working chamber of the machine can be caused to undergo a motoring cycle to enable the machine to output more power than is received from a motor driving the machine. An accumulator can be used to provide a source of hydraulic compliance. The machine can be controlled using pressure control, flow control, feed forward control or variable power/variable power limit control.

摘要： 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.

摘要： 1 Abstract (Figure 3) 3 Fluid-Working Machine Valve Timing 5 A fluid-working machine has a working chamber of cyclically varying volume, high 6 and low pressure manifolds, and high and low pressure valves for regulating the flow 7 of fluid between the working chamber and the high and low pressure manifolds 8 respectively. A controller actively controls at least one said valve to determine the 9 net displacement of working fluid of the working chamber on a cycle by cycle basis. 10 At least one said valve is a variable timing valve and the controller causes the valve I I to open or close at a time determined taking into account one or more properties of 12 the performance of the fluid working machine measured during an earlier cycle of 13 working chamber volume. Properties of the opening or closing of a monitored valve 14 may be taken into account. The variably timed valve may therefore be opened or 15 closed at an optimum time to achieve efficient and reliable operation of the fluid 16 working machine. The magnitude of the opening or closing force applied to a valve 17 member may also be varied.

摘要： A ring cam for a fluid-working machine is formed from a plurality of segments. The segments have piston facing surfaces together defining a working surface of the fluid-working machine. The segments comprise a leading cooperating formation 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 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. The cooperating formations interlock and rollers are thereby handed over smoothly from one segment to the next irrespective of slight variations in alignment due to manufacturing tolerance or wear.
