摘要： Methods, systems, and techniques for harnessing wind energy use a tethered airfoil and a digital hydraulic pump and motor, which may optionally be a combined pump/motor. During a traction phase, a wind powered airfoil is allowed to extend a tether and a portion of the wind energy harnessed through extension of the tether is stored prior to distributing the wind energy to an electrical service. During a retraction phase, the wind energy that is stored during the traction phase is used to retract the tether. The digital hydraulic pump and motor are mechanically coupled to the tether.

摘要： A turbine, wherein a propeller is mounted to said turbine, rotatable around a propeller axis, wherein a multi piston pump is provided, said multi piston pump being drivable by said propeller for pressurizing a pumping fluid, wherein the multi piston pump comprises a central part and a drive ring extending around the central part, wherein the central part comprises a series of piston-cylinder assemblies which are each compressible and extendible in a respective radial direction with respect to a common central axis, wherein each of the piston-cylinder assemblies is directly or indirectly engageable by the drive ring for radial compression thereof, in particular for pressurizing said pumping fluid, wherein at least one of the piston-cylinder assemblies is provided with a hydraulic and/or pneumatic biasing means for biasing, at least selectively biasing, at least part of that piston-cylinder assembly towards engagement with the drive ring, in particular substantially independent of and/or complementary to a biasing by a pressure of pumping fluid at that piston-cylinder assembly.

摘要： Embodiments of the invention provide a pump assembly for a hydraulic tool. The pump assembly can include a reciprocating element that is configured to move between a retracted position and an extended position, a cam surface in the reciprocating element that can engage cam followers, a rotating element that can receive rotational input, and a base that can at least partially surrounds the rotating element. Movement of the cam followers along the cam surface can move the reciprocating element from the retracted position to the extended position.
