Abstract:The development digital hydraulics demands higher performance on high-speed on/off valves. In order to fully exploit the energy saving advantages of digital hydraulics, advanced high-speed valves are expected to possess a fast response and a large nominal flow rate simultaneously. Energy-coupled-actuator (ECA) utilizes the shear working mode of magnetic rheological fluid (MRF) to achieve reciprocating motion of the valve spool through the coupling/decoupling of a pair of disks and a translational piece and its… Show more
