The article offers information on the energy efficiency of variable-displacement pumps to match hydraulic power transmission to a changing load with the use of alternating-current (ac) hydraulics. Topics mentioned include the three architectures for developing positive-displacement pumps such as bent axis, swash-plate axial piston, and vane, the new ac hydraulics approach for power transmission, and the benefits provided by using the radial piston architecture for the ac pump.
