摘要： An adaptive hydraulic pressure generator is provided for systems in which the mechanical force producing energy varies significantly, especially for wave energy systems. The pressure generator includes at least two fluid chambers with a piston surface/displacement surface arranged to reciprocate with the fluid chamber, whereby the piston surface/displacement surface acts on the fluid in the chamber by means of the said mutual reciprocating movement. The pressure generator is equipped with a control system which is arranged to connect the chambers to each other and/or to different pressure ducts in such a way that the effective area of the piston/displacement surfaces changes in accordance with the changes in the driving force exerted on the piston/displacement surfaces and/or the body forming the fluid chamber in such a way that the pressure produced by the pressure generator in the fluid supplied to the application exceeds the threshold pressure.

摘要： A wave power capture system includes a double acting piston arrangement in which reciprocation of the piston arrangement as a result of wave action to causes hydraulic fluid to be pumped into a hydraulic supply to a hydraulic motor and the flow and differential pressure of the double acting piston may be different to the flow and differential pressure provided to the hydraulic supply and that such difference is variable. Various ways in which this is achieved are described including: a duct access to which is controlled by a valve connected between the outputs of the reciprocation double acting piston arrangement; a double headed piston in a cylinder with one end of the cylinder hydraulically connected to one output of the reciprocating double acting piston arrangement and the other end the cylinder to the other output of the double acting piston arrangement: one or more pairs of piston operated pressure intensifiers, the low pressure side of one of each of the pairs of pressure intensifiers being connected hydraulically to one output the double acting piston arrangement and the low pressure side of the other of each of said pairs connected hydraulically to the other output of the double acting piston arrangement, and the high pressure side of each pair of pressure intensifiers being connected through one way check valves to the hydraulic supply of said hydraulic motor and wherein the rods of the pairs of intensifiers are connected together to that they drive one another and wherein one charges from its low pressure input and supplies a higher pressure output, while the other returns an uncharged position; or a combination of the above. Alternatively a variable hydraulic intensifier may be employed.

摘要： Anlage zur Nutzung der Meereswellen vorzugsweise zur Erzeugung von elektrischer Energie und zur Dämpfung der Wellenergie im Bereich der Küstenzonen mittels eines Schwimmkörpers mit entsprechender Formgebung, der in einem bis zu 90% getauchten Zustand in der Welle schwimmt und von den Wassermassen der Welle sowohl in vertikaler als auch horizontaler Ebene hin und her bewegt wird. Diese Hin- und Her-Bewegungen über Gestänge, die über Gelenke mit dem Schwimmkörper und einem auf dem Meeresboden verankertem Gestell mit einer Pendelvorrichtung verbunden sind, werden als lineare Bewegungen zur Erzeugung von elektrischer Energie oder hydraulischer Energie über entsprechende Vorrichtungen in der Pendelvorrichtung genutzt.
Die elektrische Energiegewinnung erfolgt durch den in der Pendelvorrichtung eingebauten elektrischen Lineargenerator, der die Hin- und Her-Bewegungen des Gestänges direkt nutzt, oder durch einen in der Pendelvorrichtung eingebauten rotierenden elektrischen Generator, wobei die Hin- und Her-Bewegungen des Gestänges über eine Zahnstange und die damit verzahnten Ritzeln, welche gegenläufige Freiläufe besitzen, in eine in die gleiche Richtung wirkende Drehbewegung umgeformt und zum Antrieb des elektrischen Generators genutzt werden.
Neben der Gewinnung von elektrischer Energie ist die Gewinnung von hydraulischer Energie vorgesehen, dazu werden über die Hin- und Her-Bewegungen des Gestänges die Kolben der im Pendelgehäuse gegenläufigen ventilgesteuerten hydraulischen Pumpen angetrieben.
