Apparatus and method for extracting wave energy

Apparatus and method for extracting the tremendous energy from a wave pattern as for example on the surface of a body of water which comprises a plurality of movable members so shaped that the surface of the member which engages the incoming wave causes the member to rotate about a substantially horizontal axis and remove energy from the wave and wherein the rear portion of the movable member is constructed so as to move with minimum energy transfer between the movable member and the fluid. The energy extracted by the movable member is converted into a hydraulic, electrical, mechanical, or chemical energy so as to allow the wave energy to be directly converted into useable form.

The present invention relates to a shaft device of a rocking piston pump, and more specifically, a pumping fluid and an eccentric shaft drive leaking toward the eccentric shaft by installing a flexible cylindrical cover around the eccentric shaft instead of a mechanical seal, which is a conventional shaft device. This invention relates to a shaft device of a rocking piston type pump which prevents mixing of lubricating oils and prevents pumping fluids from flowing out of the pump. The axial shaft is blocked by a separate cover cylinder around the eccentric shaft. By preventing the mixing of the lubricating oil and the pumping fluid required to prevent damage of the various parts such as bearings and packing also has the effect of maximizing the life of the pump.

Swing vane-type pump actuator which prevents fretting corrosion

A test for operation over an extended period was performed on a high-power swing pump in which an independent seal device was employed, and a swing vane pump of a high-efficiency, pendulum-type wave power generating system was applied to use a swing vane-type pump actuator at a high pressure of 25MPa, as opposed to conventional, commercially available actuators. Test results showed that abrasive wear occurs by fretting corrosion at high-strength joint surfaces of hydraulic components in which a high-strength direction and a low-strength direction oppose each other. A need exists to quickly overcome abnormal wear and put a high efficiency wave power generating system into practical use. When a cylinder, the strength of which is low in the radiation direction with respect to a center shaft, and a side cover, the strength of which is high in the radiation direction, are coupled together to form joint surfaces therebetween, a cylindrical portion, which protrudes toward the cylinder, is arranged at the cylinder cover, such that the same distortion occurs to the side cover as that of the cross-section of the cylinder, which is distorted to a nearly elliptical shape by high-pressure working fluids. In addition, a pipeline, with which a low-pressure side working chamber is always in communication, is installed on the surface of a static vane fixed at the cylinder, wherein said surface of the static vane contacts the side cover.

The invention concerns a swash pump designed for the trans-fer of sensitive, time-critical fluids in the food-technology or bio-technology field. All the spaces (11, 15, 16) with which the fluid be-ing pumped comes in contact are included in the pumping path. Since fluid is flowing continuously through the spaces (11, 15, 16) which come in contact with the fluid, the fluid cannot settle in any one place. This makes it possible to clean the pump by simply flushing out the pump with the pump still fitted in place,

Wave energy extraction

1482085 Extracting energy from waves UNIVERSITY OF EDINBURGH (COURT) 15 Nov 1974 [15 Nov 1973 6 May 1974] 53119/73 and 19763/74 Heading F1S Apparatus for extracting energy from waves comprises a member 2 mounted for oscillation about an axis O, the leeward side of the member 2, left hand side as seen in the drawing, having a semi-circular profile centred on axis O so that the water on this side is not disturbed as waves coming from the right cause the member 2 to oscillate about its axis. This design and the leeward side, coupled with the fact that the leading edge of member 2 is designed to permit the water at varying depths to follow its natural wave movement, ensures that practically all of the wave energy is extracted for conversion into electricity. For the latter purpose, permanent magnets mounted on an inner surface of member 2 may induce currents in coils mounted on a stationary support 1. Alternatively, as shown, the member 2 and support 1 may be shaped to form a spline pump which may be coupled to a turbine generator. A plurality of members 2 may be mounted on a common linear or arcuate support 1. Alternatively, the one long support may be replaced by a plurality of sections joined together by hinges 13, Fig. 5 (not shown).
