Referring to Figure 1, the floating wave energy converter as seen at 201 is comprised of an enclosure 47 which is designed to s trap the energy of incoming waves. Further embodiments of a Wave Energy Converter being solidly attached to ground or another immovable body are not shown as they do not differ significantly in operation from those pictured in the 2s included figures other than they do not require the use of reaction plates or damper plates and their means of attachment to any fixed body are much varied and of well known technology.

Espalda, músculos, superficial Colección de ilustraciones.. FIG. 1 is a modified perspective view of a floating Wave Energy Converter incorporating a wave termination feature, self-alignment feature and off-set heave reaction plates feature in accordance with a first preferred embodiment of the invention. These unequally spaced reaction plates are solidly attached 2s to the rotatable support means by a connecting component of essentially unchangeable length but with optional lateral flexibility such as, but not limited to, a rod, pole, tube or framework. The force of suction is created as the fluid tries to fall from the lower body portion 22 but cannot because of the now closed one-way check valve 99. The condition of surface adhesion is created as the fluid attempts to break its bond with the roof of the chamber of the lower body portion 22. If the lower body z5 chamber 22 is not entirely filled with fluid because fluid has escaped during the fall of a previous wave (downward stroke with regard to the wave follower) or due to turbulence in the body of fluid, the rise of the next wave 67 causes fluid to attempt to re-enter the chamber 22 through the opening at it’s bottom, thereby 3o causing an increase in pressure of the air contained between the fluid and the roof of the chamber 22. The increase in air pressure causes the one-way valve 99 to open, thus allowing air to be exhausted from the lower chamber 22 and, thereby, allowing fluid to freely once again enter and fill the lower chamber 22 through it’s 3s open bottom.

There is immediately a corresponding drop in fluid pressure applied in the upper cylinder 192. As soon as the pressure sensor 185 in the sensor/solenoid valve 45 (as shown at 203b) determines that this pressure drop exceeds a preset amount it activates the solenoid io valve mechanism 187 by means of a linkage 183. (The solenoid switch in this particular embodiment of the invention is electrical, receiving it’s power via a power cable 181). This in turn opens a gate 193 in valve body 186. The pressurized fluid, until now being applied against the driven load by the piston 27, is now provided 15 with a path of minimal resistance through the opened valve 186, and on down a bypass tube 184. At the same time that the sensor 185 caused the valve gate 193 in the sensor/solenoid valve 45 to open, it simultaneously caused the valve gate 193 in the sensor/solenoid valve 43 to open as well by 2o transmitting a signal to it via a signal cable 176. These simultaneous valve openings allow for clear passage of the fluid in the upper cylinder 192 into the lower cylinder 193. In order to adjust for differences of volumetric pressure between the upper cylinder 192 and the lower cylinder 193 as well as for expansion, 2s contraction and other factors, an accumulator or reservoir 182 is installed into the bypass tube 184 such that the fluid 175 will extend into or exit from the accumulator 182. Thus the fluid to be evacuated from the upper cylinder 192 can enter the lower cylinder 193 freely and quickly.

As the wave follower 20 rises, the piston 27 travels to it’s left (toward it’s nominal top) within the relatively immovable cylinder 28 creating a suction within the cylinder 28 below the to piston 27. This action causes fluid to be pulled into this lower part of the cylinder 28 through the inlet at foot valve 37. As the piston 27 rises, thereby reducing the volumetric capacity in the upper part of the cylinder 28, the fluid contained within the upper part of the cylinder 28 above the piston 27 is pressurized and 15 expelled through the outlet passing through the check valve 38 and through an outlet tube 41. As the wave follower 20 now travels downward, so does the piston 27, thus reversing the action within the cylinder 28. This now creates a suction within the cylinder 28 above the piston 27. This action causes water to be pulled into 2o this upper part of the cylinder 28 through the inlet at foot valve 39. Dolor de espalda y esternon . The fluid contained within the lower part of the cylinder 28 below the piston 27 is pressurized as the piston 27 is forced downward, reducing the volumetric capacity in this lower part of the cylinder 28 and is thus expelled through the outlet passing 2s through check valve 40. The expelled, pressurized fluid from both the upward and downward strokes of the piston may then be gathered at 42 to power internal, external or separate and remote devices, systems or processes.

FIG. 2 is a detailed modified perspective view of the upper portion io of the apparatus shown in Figure 1. wherein a two-way reciprocating pump and an electricity generator are both driven devices and wherein solenoids/release valves/sensors/switches as well as external devices are powered or charged by energy produced by the apparatus itself in accordance with a ffirst preferred embodiment of the invention.

FIG. 5 is a detailed modified perspective view of a device similar to that in Figure 4. excepting that the solenoids/release valves /sensors/switches are powered by an externally charged battery or other external source of power. FIG. 3 is a more detailed modified perspective view of the two-way reciprocating pump as shown in Figure 2 and more specifically of the load release and re-establish means used. FIG. 12 is a modified perspective view of a floating Wave Energy Converter similar to the apparatus shown in Figures 10, but without lever arm linkages and also incorporating on-board reverse osmosis or mechanical pressure filtration capability (which the apparatus on Figure 10 could also be rigged with).

Further, the rear wall may be formed to enclose the wave follower in such a way as to minimize the flow of fluid past the wave follower as it rises and falls with the waves, this in order to maximize the capture and s conversion of said other forces. This design increases the wave follower s capacity to do work by focusing forces other than only floatation and gravity on the wave follower.

In this way the wave follower is suddenly 30 released of it’s load resistance. The enclosure 47 is made up of a top panel 57, a back panel 48 and two side panels 49. Dolor lumbar y sacro . Vertically mounted funnelling panels 50 are fixedly attached to the side panels 49 at an angle such that the waves 67 which enter the apparatus through an open front 53 are amplified in height as the io channel established by the funnelling panels 50 becomes narrower. A load release and re-establish means may be any hydraulic, pneumatic, mechanical, electro-mechanical or other means whose function is to momentarily release the wave follower 20 to from the driven and systemic loads of the apparatus 202 such that the wave follower 20 is allowed to find it’s own level without the influence of these load resistances. 3s follower to track the rising wave,) pops up to float virtually fully on the surface of the fluid because the wave follower has been dynamically balanced by the counterweight as was previously explained.

52 approaches or reaches its lowest point and no more work can be accomplished by the wave follower 20 moving 35 downward, the load release and re-establish means 202c senses either the levelling off of, or the beginning of a change of direction of the wave, or a drop in pressure (now in the lower -. Figure 9. describes an apparatus as seen at 209 and which is 35 very similar to that described in Figure 8 except that the driven assembly as seen at 209a converts two-way reciprocating motion to full, continuous rotary motion in one direction. 3s release valves, pressure sensing switches, height sensing switches, clutches, brakes, solenoids or release pins or cams, and which may or may not be further controlled by a programmable logic controller or similar control device in order to optimize the response of the load release and re-establish means to varying wave heights and patterns.

The pump is pivotally attached at 30 to the relatively immovable enclosure 47 of the apparatus 202 by mounting bracket 29 which allows the pump to rock backward and forward in order to maintain alignment with the piston rod 26. The piston rod 26, being attached s to pivotal joint 25, allows piston rod 26 to stay aligned with the rest of the pump assembly as the lever arm extension 172 rocks back and forth. In trying to deal with this problem, others have relied on the local wind direction to align their devices. Thus the mechanical advantage modifier means allows for earlier unlocking and therefore, travel of the wave follower, rendering it operable in times of smaller io than normal wave heights when other devices designed for normal wave patterns would cease to function due to their inability to unlock at smaller wave heights. Figure 5. describes a wave energy converter 205 similar to that described in Figure 4 except that the sensor/solenoid valves 43 and 45 are electrically powered, receiving their power via cables 69 from a battery 70 which has been charged externally.

In practice, this has proven to be less than ideal as very often, local wind direction differs from the 25 direction of the larger, more energy rich swells which have been generated far off by winds blowing in a direction different than the local winds. Alternately, the threaded shaft 113 of the linear drive ball screw 202b may be fixedly connected to the drive shaft 174 at 119 and at. 3o selectively and progressively flexible such as are the blades of some windmill propellers defined as self-furling. FIG. 4 shows a minor variation of the apparatus shown in Figure 3 wherein a two-way reciprocating pump is a driven device and wherein solenoids/release valves/sensors/switches do not require electric power.

2o below the undulating action of the waves are attached in a plurality of more than two such that the varying distances between the plates will minimize undue vertical movement of the apparatus due to any harmonic movement of the water below normal wave action depth. Improved efficiency s will be achieved by increasing the effective travel of the device’s driving component -hereafter called a wave follower- for any given wave height. This capability will become apparent as.-.
