摘要： A hydraulic system (1, 50) for a load handling vehicle comprises lifting actuator (2, C1) that operates in a load lifting mode in which a load is induced on the actuator, and a load lowering mode in which the actuator provides hydraulic power PI to the hydraulic system. An auxiliary hydraulic actuator (4, 6, 8, C2) is also provided that has a hydraulic power demand P2. A hydraulic pump (10, 58) directs hydraulic power to the hydraulic lifting actuator and the at least one auxiliary hydraulic actuator. The hydraulic system is configured such that when the hydraulic lifting actuator is in the load lowering mode, it is required to simultaneously actuate the at least one auxiliary hydraulic actuator, and PI is greater than or equal to P2, hydraulic power may be channelled directly to the auxiliary hydraulic actuator from the hydraulic lifting actuator in order that the at least one auxiliary hydraulic actuator is actuated entirely by the hydraulic power from the hydraulic lifting actuator, and without the use of the pump.

摘要： A control valve assembly for a load handling vehicle such as forklift comprises a valve body having a bore and a spool located within the bore that is axially movable along the bore between at least two operating configurations. The valve body includes a service port connected to a hydraulic actuator, a pressure port connected to a pump, and a tank port connected to a hydraulic tank reservoir. The valve is reconfigurable between first and second operating configurations. In the first operating configuration the spool defines a fluid pathway connecting the pump port, the service port and the tank port such that in a first flow direction fluid is able to flow from the pressure port to the service port and the tank port, and in a second flow direction fluid is able to flow from the service port to the pressure port and the tank port. The spool is also controllable in the first operating configuration to variably restrict flow to the tank port. In the second operating configuration the spool defines a fluid pathway connecting the pressure port and the actuator port, and is controllable to variably restrict flow between the pressure port and the actuator port.

摘要： A tube coupling apparatus includes first and second clamping jaws that are mounted on a tool body. The clamping jaws are movable relative to each other between an open configuration in which they are receive a compressible tube connector, and a closed configuration in which they apply a compression force to compress the compressible tube coupling about one or more tube members. An actuator is arranged to move at least one of the clamping jaws to the closed configuration and a controller is operative to control the actuator. A sensor is provided that is arranged to determine a system parameter indicative of the compression force applied to the coupling by the clamping jaws and to progressively increase the compression force of the clamping jaws during a fitting operation. The controller monitors the system parameter data from the sensor and automatically controls the actuator to prevent the compression force exceeding a predetermined threshold based on the sensor data.

摘要： A pressure swing adsorption system is disclosed which includes first and second chambers (110, 112) each containing an adsorption medium. In use,a fluid is directed to flow over the adsorption medium in one of the chambers to adsorb contaminants in the fluid while the adsorption medium in the other of the chambers is regenerated by desorption of adsorbed contaminants. The system includes: a purge conduit which extends between the chambers for delivering fluid from the online chamber to the regenerating chamber, the purge conduit containing a flow restrict or (160) for controlling the volume of fluid which can flow through the purge conduit; a re-pressurisation pathway (167) which extends between the chambers for delivering fluid from the online chamber to the regenerating chamber, bypassing the flow restrict or; a re-pressurisation control valve (168) for controlling the flow of fluid in the re-pressurisation pathway, which comprises a housing (800) having a cavity within it with a port (854a, 856a) for flow of fluid along the pathway and a valve member (864, 869) which can move in the cavity between (i) a closed position in which it engages the port and restricts flow of fluid through the pathway and (ii) an open position in which it is displaced from the port allowing flow of fluid through the pathway, the valve member being biased towards its closed position by the action on the valve member of fluid from the online chamber;and an actuator (864, 868) which can act on the valve member to move it from its closed position.

摘要： There is disclosed an actuator (55) for a separator (5) for separating contaminants from a fluid stream which includes entrained contaminants. The actuator is arranged to move along an actuator axis (56) to adjust an open cross-sectional area of at least one aperture (29) of the separator through which the fluid stream flows, and comprises a flexible diaphragm (31) for occluding the at least one aperture, and a support assembly (33) for the flexible diaphragm. The support assembly is movable along the actuator axis carrying the flexible diaphragm and has a lower support member (58) and an upper support member (60) mounted on the lower support member so that a portion of the flexible diaphragm is located between the upper and lower support members. The lower support member comprises a radially extending support portion (62) and an axially extending support portion (64) coupled to the radially extending support portion. The upper support member comprises a radially extending support portion (66) and a diaphragm anti-inversion feature (68) coupled to the radially extending support portion. The diaphragm anti-inversion feature extends in an axial direction so that it axially overlaps at least part of the axially extending support portion of the lower support member.
