摘要： Apparatus and methods for metering fluid to a fluid actuator. An example apparatus may include a hydraulic actuator and a fluid chamber. The fluid chamber may include a piston slidably movable between first and second ends of the fluid chamber and dividing the chamber into first and second chamber portions, a first port extending into the first chamber portion, and a second port extending into the second chamber portion. The apparatus may further include a hydraulic directional control valve operable to direct a fluid from a fluid source into one of the first and second ports to cause a volume of fluid to be discharged out of the other of the first and second ports into the hydraulic actuator to actuate the hydraulic actuator by a distance corresponding to the volume of fluid received by the hydraulic actuator.

摘要： An intelligent knuckle boom control system is disclosed where hoist and stick cylinders raise and lower main and stick booms, respectively, a base end control valve controls flow to the hoist and stick cylinder base ends, a hoist rod control valve controls flow to the hoist cylinder rod end, and a stick rod control valve controls flow to the stick cylinder rod end. A microprocessor computes control signals to direct flow through the control valves based on operator commands and boom position readings. The system can include an energy storage system for storing excess energy and releasing the stored energy, where the microprocessor directs storage of excess energy and release of stored energy. The energy storage system can include a hydraulic accumulator, an accumulator control valve and hydraulic pressure sensors; where the microprocessor receives pressure sensor readings and computes accumulator control valve control signals.
