6 Remotely reconfigurable high pressure fluid passive control system for controlling bi-directional piston pumps as active sources of high pressure fluid, as inactive rigid structural members or as isolated free motion devices US15804426 2017-11-06 US10030645B2 2018-07-24 Kenneth A.

A bi-directional pump system that can be configured for a plurality of operating modes. The bi-directional pump system includes a plurality of bi-directional pumps each having their own valving system that are connected to a common high pressure manifold, a low pressure manifold and a suction manifold. Via the respective valve systems, each pump can be configured into: (1) a single-acting pumping mode; (2) a double-acting pumping mode; (3) an inactive free motion mode; and (4) an inactive rigid mode. One exemplary application of the bi-directional pump system is on an articulated wave energy conversion system that consists of three floating barges: a front barge, a center barge and a rear barge where the front barge and center barge are hingedly connected as are the center barge and the rear barge. A first set of the bi-directional pumps span the first hinge connection and the second set of bi-directional pumps span the second hinge connection. The bi-directional pump system intakes sea water and, using wave energy, outputs a high pressure flow of sea water for water desalination and/or for driving electrical generators.

10 Dual, coupled check valve for direct drive, reversible power sources for hydraulic systems US10538734 2004-03-18 US20060070377A1 2006-04-06 Harry Last
An invented dual, coupled check valve mechanism is described for a direct drive, reversible hydraulic power source for hydraulic circuits that includes a manifold hydraulically coupled to the respective input/output ports and a reservoir of the hydraulic power source defining a translation passageway having mid-passage drain hydraulically coupled to the reservoir, where each end of the translation passageway has an angled annular valve seat opening to larger diameter plenum containing a check valve ball. A translating rod with a length greater and a circumferential diameter less than that of the translation passageway located in the translation passageway prevents the respective check valve balls from simultaneously seating on the valve seats at the respective ends of the translation passage way.

14 Hydraulic power transmission US535679 1974-12-23 US3956893A 1976-05-18 Clifford E. Putnal
Power is transmitted between reciprocating crank drives by piston, pump and motor assemblies of the single-acting type interconnected in an open fluid circuit. A valve arrangement in the fluid circuit maintains the pump assembly and the pressure conduits interconnecting the assemblies completely filled with fluid during the return strokes of the pump and motor assemblies.
15 Hydraulic stroke increaser US3782123D 1972-01-11 US3782123A 1974-01-01 MUSCHALEK B
A stroke increaser for use in well pumping systems and the like has a fluid motor, with the cylinder of the fluid motor attached to an actuator, such as the bridle of a walking beam assembly, and the piston of the fluid motor connected to a longitudinally extending hollow polish rod. A fluid pump has a cylinder arranged in the pump assembly and has a piston connected to the other end of the hollow polish rod. A transverse bore is arranged in each end portion of the hollow polish rod. A hydraulic fluid is provided in the cylinders in the hollow polish rod. When the actuator begins an upward stroke, both pistons are in the bottom portion of their respective cylinders. The piston of the fluid pump will be forced upwardly with respect to its associated cylinder by the upward movement of the actuator. The hydraulic fluid will be forced from the cylinder of the fluid pump through the hollow polish rod and into a cylinder of the fluid motor. The piston of the fluid motor will thus be forced upwardly relative to the cylinder of the fluid motor and increase the stroke of sucker rods attached to the piston of the fluid pump. The above process is reversed for a downward stroke of the actuator.
