Abstract:
A pneumatic linear actuator with a manually adjustable stop mechanism integrated into the device such that the actuator mechanism and the stop mechanism are co-linear. The stop mechanism limits the travel of the actuator by turning a handwheel. The mechanisms are completely sealed and/or enclosed and a gear-reduction position indicator is included. Forward and reverse acting variations are presented.

Abstract:
A magnetic braking system for inhibiting excessive motion between a float (5) and a column (3) intended to be placed in a body of water; with the float (5) and column (3) moving relative to each other as a function of the waves present in the body of water. The braking system includes a permanent magnet assembly (PMA) mounted on, and attached to, one of the float (5) and column (3) and a coil assembly (or conductive plate) mounted on, and attached to, the other one of the float (5) and column (3). The braking system is mounted such that motion between the float (5) and column (3) is inhibited when the displacement of the float (5) relative to the column (3) exceeds a predetermined operating range.
Abstract:
A WEC system embodying the invention includes a column and shell, arranged to move relative to each other, and a lever-like apparatus having an input end and an output end and an intermediate point, between the two ends, the intermediate point being rotatably connected to the column. The input end is connected to the shell and moves at the same velocity and in the same direction as the shell. The output end moves in the opposite direction and at a rate which is a multiple of the shell velocity. The multiple being a function of the ratio of the length of the intermediate point to the output and input ends. In systems embodying the invention, one of two components (a PMA or an ICA) of a linear electric generator may be attached to the shell and the other of the two components may be attached to the output end of the lever-like apparatus to produce high relative velocity between the two components resulting in higher amplitude and higher frequency output voltages.

Methods, apparatus systems which utilize gas-lift pumping in producing mechanical and/or electric power. A system and method for generating energy from electrolysis performed at a substantial depth inc includes generating gas by an electrolysis process at a substantial depth from a surface of a body of liquid. The system also includes capturing the generated gas in a containment chamber and generating mechanical energy as a function of a rising of the containment chamber with the captured gas. In another embodiment, the system and method include generating gas by an electrolysis process at a substantial depth from a surface and providing a working liquid from the surface to the electrolysis process at the substantial depth. The system and method further include capturing the generated gas in a containment tube and generating mechanical energy as a function of the captured gas.
Abstract:
The object of the invention is to provide a reliable and inexpensive combination of a chamber and a piston to be used in any device where such a combination is needed so that it complies with specific demands towards the operation force for e.g. pumps, specifically manually operated pumps. By a device comprising a chamber and a piston positioned inside the chamber said chamber and said piston relatively movable to each other in a predetermined direction of movement between a first position and a second position of which the cross-section of the chamber in a plane perpendicular to the direction of movement is larger at the first position than at the second position, the change in the cross section of the chamber is essentially continuous between the first position and the second position and the cross-section of the piston in a plane perpendicular to the direction of movement is arranged to adapt itself to the cross-section of the chamber. It is further possible that the piston has a fixed geometrical shape, that the wall of the chamber has different sizes of cross-sections in the direction of the movement and is arranged to adapt itself to the piston. Moreover, both the piston and the wall of the chamber can adapt itself to each other.
Abstract:
Offenbart ist ein Gehäuse für einen hydraulischen Radialkolbenmotor mit einem ersten Gehäuseteil und mit einem zweiten Gehäuseteil, zwischen denen ein Hubring angeordnet ist, der somit ein mittleres Gehäuseteil bildet. Über Nocken des Hubrings wird im Betrieb des Radialkolbenmotors in umlaufenden Zylinder-Kolben-Einheiten eine Hubbewegung erzeugt. Insbesondere handelt es sich dabei um eine Hubbewegung der Kolben, die sich über eine jeweilige Rolle am Hubring abstützen. Am Hubring ist zumindest eine erste Dichtung angelegt, die in einem montierten Zustand des Gehäuses auch am ersten Gehäuseteil anliegt. Wenn bei der Montage des Gehäuses das erste Gehäuseteil auf den Hubring abgesenkt wird, ist ein Verschieben und ein Abfallen der ersten Dichtung ausgeschlossen. Offenbart ist weiterhin ein Verfahren zur Montage eines Gehäuses für Radialkolbenmotoren, bei dem zunächst die erste Dichtung am Hubring angebracht oder auf diesen aufgelegt wird, und danach das erste Gehäuseteil auf den Hubring und damit auf die erste Dichtung abgesenkt wird.
Abstract:
A compressed-air energy storage system according to embodiments of the present invention comprises a reversible mechanism to compress and expand air, one or more compressed air storage tanks, a control system, one or more heat exchangers, and, in certain embodiments of the invention, a motor-generator. The reversible air compressor-expander uses mechanical power to compress air (when acting as a compressor) and converts the energy stored in compressed air to mechanical power (when acting as an expander). In certain embodiments, the compressor-expander comprises one or more stages, each stage consisting of pressure vessel (the pressure cell) partially filled with water or other liquid. In some embodiments, the pressure vessel communicates with one or more cylinder devices to exchange air and liquid with the cylinder chamber(s) thereof. Suitable valving allows air to enter and leave the pressure cell and cylinder device, if present, under electronic control.

Изобретение относится к области энергетики. Двигатель гидравлический радиальный содержит герметичный полый корпус 1, в котором сделана эллиптическая цилиндрическая поверхность 3, образующая участки скатов 4, на которых силы давления поршней совершают работу перемещения поршней, и подъемов 5, вал и расположенные на нем роторы 6. По центру вала сделан общий канал 15, сообщающийся с радиальными каналами 14, входящими в цилиндры 7, которые сделаны в теле роторов. В цилиндрах сделаны отверстия сливов 8. В общем канале установлена распределительная труба 16, имеющая по два окна 19 для каждого ротора. С обеих сторон к торцам роторов прижаты шайбы 27, имеющие по две сливных прорези 30, расположенные на диаметре отверстий сливов. В цилиндрах установлены поршни 9, оснащенные катками 12, движущимися по цилиндрической поверхности, отчего в радиальных каналах возникают центробежные силы инерции жидкости, вызывающие повышение давления. При работе двигатель постоянно находится в состоянии неустойчивого механического равновесия.
