BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to the field of generating energy utilizing water as a force to create energy which is used to facilitate the generation of power.
2. Description of the Prior Art
The present inventor is also the inventor of U.S. Pat. No. 8,974,192 issued on Mar. 10, 2015 for the invention entitled “BIOMORPHIC WAVE ENERGY COLLECTOR”.
SUMMARY OF THE INVENTION
The present invention utilizes the kinetic energy of waves through said invention to capture, push, and pressurize water to shore to convert with water turbines to generate electrical energy.
The present invention relates to generation of energy with a simple pump using the hydrodynamics of wave motion to act on a parallelogram compression mechanism with a flexible bladder between its walls. The force on the mechanism from two directions (towards the shore and away from the shore) impacts force on the mechanism to fill the bladder and compress to push sea water to shore. This process is managed with check valves to direct the pressurized sea water to shore through pipes where a turbine is used for conversion to hydropower.
The present invention is a parallelogram structure which is affixed to a shoaling reef structure and constructed of pipes. These pipes could be constructed of many different types of plastics including polyvinyl chloride, polyethylene, polypropylene, polycarbonate and thermoplastic polymers. The preferred material wold be High Density Polyethylene (HDPE). The multiplicity of pipes can be filled with air for deployment or filled with water and which are submerged in the ocean and affixed to the ocean floor by a multiplicity of anchors. A colony of parallelogram wave energy collectors (WEC) can be secured on the pipe body of the reef while floating in a harbor and then the reef can be towed and eventually anchored to the bottom of the ocean floor just off shore of any beach. The multiplicity of pipes any of which can also be used as pluming pipes.
The reef designed to cause wave shoaling and can be any size to fit a wave climate for any area. The dedicated plumbing pipes can run from any distance and extend all the way up to and underneath the shoreline and into a structure on shore which retains the turbine to convert the head pressure of the sea water to energy. The pipes of the offshore reef will vary according to the local wave climate of any area but will be approximately 300 feet in length. The power converting turbines could be a number of different hydropower turbines such as a Pelton turbine.
The present invention utilizes the concept of a parallelogram device which can be rotated in one direction such as away from the shore and then in an opposite direction toward the shore, to build up water in a diaphragm through one-way water entrance valves which fills the diaphragm with water and which through the lower one-way valves causes the water under pressure to exit a compressed diaphragm and to enter a multiplicity of pipes. The water is forced out through lower one-way check valves which in turn are connected to the plumbing pipes. Flowing water is directed onto the blades of a turbine runner, creating a force on the blades. This converts the force of water from the longitudinal pipes to useable energy.
Prior to hitting the turbine blades, the water's pressure (potential energy) is converted to kinetic energy by a nozzle and focused on the turbine. Water turbines are generally considered clean power producers, as the turbine causes essentially no change to the water. They use a renewable energy source and are designed to operate for decades. They produce significant amounts of the world's electrical supply.
The present invention is a unique source of generating high pressure water from the ocean to drive a water turbine to generate electrical energy.
The present invention utilizes the concept of having a parallelogram structure which houses a compressible diaphragm which has at least one or more one-way intake valves which are inserted into the top of the inflatable diaphragm and at least one or more one-way exit valves inserted into the bottom of the diaphragm, which bottom one-way valves are connected through a fluid connection into one or more of the pipes which transmit the water under pressure to the water turbine.
The present invention is submerged in water and anchored to the center of the reef, which is the highest elevation and away from the sand intrusion issues at the bottom. This also positions the parallelogram structure closer to the surface in order to take advantage of the higher energy in that part of the inshore water column. The parallelogram wave energy collector includes the diaphragm which is sandwiched between a pair of plates which in turn are affixed to hinges of the parallelogram. This enables the walls to compress in one direction and then in an opposite direction by the force of water hitting the plates and causing the plates and diaphragm to compress in a given direction. The force causes the diaphragm to be compressed, generating water under pressure which then fills the pipes. The pipes initially are filled with water and are sealed at their ends which are facing away from the shore and have an open end which extends into the structure where the water turbine is located. All of the one-way check valves are structured to be respectively above or below the location of the plates.
As the parallelogram wave energy collector is caused to move in one direction or another, the plates are rotated to a position where they are almost flat. Compressing the diaphragm generates pressurized water which is then fed into the longitudinal pipes. This pressurized water then passes through these longitudinal pipes to the water turbine to enable the water turbine blades to be rotated to generate electrical energy. The water turbine is one example of a device used to generate power from the force of water.
It is therefore an object of the present invention to create a parallelogram structure which can be rotated in one direction and in an opposite direction by the force of the ocean's water moving toward the shore and then receding from the shore. The force of the ocean's water enables a diaphragm filled with water to be compressed to send compressed fluid into receiving pipes which are filled with water and have the water under pressure strike the blades of a water turbine to create electrical energy.
The present invention envisions having a multiplicity of parallelogram structures at spaced apart locations along the length of the feed pipes so that the feed pipes are continuously filled with water under pressure to generate pressurized water to hit the blades of the water turbine.
The selected number of water feed pipes can vary. There should be at least two such lengthwise water feed pipes and any number beyond that. There is no specific length that is required for the water feed pipes but they must be of sufficient length to extend from the location where the parallelogram water energy collector is anchored to the location of the water turbine or other source of power generation which is impacted by the force of water.
It is an object of the present invention to create a source of pressurized water to push the blades of a turbine. Alternatively, the head pressure can be directed to a hill top reservoir or water tanks and another pipe running from that source to the turbines. The common hydrodynamic conversion is proven common for energy needs in rivers and with dams and it can also be used to convert the kinetic energy of waves to useable electricity in an environmentally friendly manner.
Any ocean area is affected by tides which play a significant role in the present invention. The tides are affected by natural forces occurring from the rotation of the earth, and also the effect of the moon directly responsible for the way tides go in and out in different locations of the earth. Gravity also plays a role in the way the tides are caused to go in and out depending upon where the ocean surfaces are relative to the equator. The height of tides generally can vary from one foot to over 10 feet of difference. The shoaling reef will be fixed on the seafloor as described and as the platform for the wave energy collector (WEC). The parallelogram design includes the top and bottom of the parallelogram structure being parallel to the seafloor and generally the water surface. The bottom of the WEC will be connected to the reef in a structural way. If another intermediate parallelogram is first connected to the reef, the WEC can now be connected to the top plate of that new parallelogram. If two bottom axils of the WEC are extended and bent upward, it will serve to hold two floats, one on each side of the WEC. They would be next to the WEC on each side. The floats would serve to locate the top surface and would automatically locate with any tide, high or low. This base addition would allow the WEC to be exactly located just below the surface. The floats could be a bright color to warn boats of the location(s) of the WEC(s).
The present water parallelogram wave energy collector is also used in conjunction with the present inventor's artificial surfing reef described and claimed in U.S. Pat. No. 5,207,531 issued on May 4, 1993 and improved and upgraded in U.S. Pat. No. 8,517,631 issued on Aug. 27, 2013.
Further novel features and other objects of the present invention will become apparent from the following detailed description and discussion.

DETAILED DESCRIPTION OF EMBODIMENTS OF THE INVENTION
Although specific embodiments of the present invention will now be described with reference to the drawings, it should be understood that such embodiments are by way of example only and merely illustrative of but a small number of the many possible specific embodiments which can represent applications of the principles of the present invention. Various changes and modifications obvious to one skilled in the art to which the present invention pertains are deemed to be within the spirit, scope and contemplation of the present invention.
Referring to FIG. 1, there is illustrated one full embodiment of the present invention parallelogram wave energy collector 10. The components will be described to the extent that they are shown in FIG. 1 and will be described in greater detail where they are better illustrated in subsequent figures. The longitudinal pipes which carry the water from the parallelogram structure to the location of the water turbine or other power generating member are illustrated in FIG. 1, with the longitudinal pipes numbered 21, 23 and 25. Additional views of the water carrying pipes 21, 23 and 25 are illustrated in FIG. 4. The entire parallelogram wave energy collector 10 is oriented so that the pipes are facing toward or away from the shoreline with the respective remote end of the pipes 20F, 22F and 24F facing away from the shoreline. Each of these ends is fully sealed so that water cannot escape through the remote ends 20F, 22F and 24F. On the opposite end which is the near end, the near ends 20, 22 and 24 are open so that water can flow out of the pipes at the locations of the pipes which are adjacent the near ends extending to the shore and usually buried under the sand until the open ends 20N, 22N and 24N reach a housing which contains a water turbine so that water exiting the near ends of the pipe 20N, 22N and 24N is exiting under high pressure as will be described later and the water is directed to hit the blades of the water turbine to cause the blades to rotate and generate electrical energy in accordance with water turbine principles. The water turbine is an example of a device used to generate power from the force of water. A turbine does not generate electrical energy. It converts kinetic energy to electrical energy and the water pressure created in the present invention is used to convert wave energy to water pressure and flow. It is the water pressure and flow that is converted by the water turbine to electrical energy.
Referring to FIG. 4, the parallelogram wave energy collector 10 is anchored to the floor of the ocean by anchor bars such as 200 and 210. It will be appreciated that the anchor bars are at spaced apart locations along the length of the pipes so that the entire parallelogram wave energy collector 10 is solidly anchored to the sea bed floor. As described, the anchor bars are attached to the pipes 21, 23 and 25, and the pipes are then anchored to the sea floor bottom by at least one anchor bar. The anchor bars are illustrated as 200 and 210 but it will be appreciated that any anchors which serve to anchor the pipes 21, 23 and 25 to the ocean floor are within the spirit and scope of the present invention.
Referring to FIG. 2, the next components of the parallelogram wave energy collector 10 are the structural rotational mechanisms which enable the parallelogram wave energy collector 10 to rotate in directions away from the shore and toward the shore. These consist of two transverse pipes 30 and 32. Transverse pipe 30 has a first end 30A and a second end 30B which are respectively rotatably retained to a first retaining structure 300 and a second retaining structure 310. The second lower transverse pipe 32 has an end 32A and a second end 32B which are also rotatably connected to oppositely disposed lower structural members 300 and 310.
Referring to FIG. 1 and FIG. 2, the upper transverse pipes 34 and 36 respectively have first end 34A and 36A and second end 34B and a second end not shown, which second end is opposite end 36A, which are respectively rotatably connected to a pair of upper structural members 320 and 330 which in turn serve to rotatably retain transverse upper pipes 334 and 336. Further, referring to FIG. 1 and FIG. 2, there are lower transverse pipes 30 and 32 having respective ends and respective second ends 32B and 32D which are rotatably connected to a pair of lower structuring members 300 and 310.
Referring to FIGS. 5 and 7, the transverse structure has a top section 400 which rotatably retains a flotation member 72 having a first end 72A and an opposite second end 72B illustrated in FIG. 1 but shown not illustrated in FIG. 1. The lower base structure 300 has a retaining bolt 302 and the opposite retaining structure has a retaining bolt not shown. The flotation member 72 has a transverse opening 72-O from one end 72A to 72B. The flexible, stretchable parallelogram member illustrated in FIG. 1 and also in FIG. 7 stretches through the transverse opening of the rotation member 72 and then extends around opposite ends of transverse pipes 34A and 36A through sections 66 and 64 and then extend into bolt retaining member 302 and oppositely extend around the opposite ends 34B (second end not shown) of upper transverse pipes 34 and 36 and then are retained by an oppositely disposed retaining member bolt affixed to structure member section 300. The flotation member 72 can also be described as a flotation or ballast element.
As illustrated in FIG. 2, the lower transverse pipe 30 and 32 and upper transverse pipe 34 and 30 contain a pair of retaining sleeves. Two of them 110A and 120A are illustrated in FIG. 2. It will be appreciated that there are comparable such retaining sleeves which are wrapped around transverse pipes 30 and 36. Each retaining sleeve is wrapped around the pipe and respectively has an opening such as 110A and 120A. Affixed to the openings are a first plate 80 which is affixed through threaded screws which extends through openings 110A and 110B and oppositely disposed sleeves 130 and 140 illustrated in FIG. 1 which also have comparable openings to retain transverse plate 80. It will be appreciated that the second transverse plate which is not illustrated is affixed between the retaining members affixed to transverse pipes 36 and 32 so that the pair of plates are oppositely disposed between an opening between the transverse pipes 30 and 32 at the bottom and 34 and 36 at the top.
Retained between the transverse pipes is a flexible diaphragm 90 which can be made of flexible material such as polyurethane. A section of the polyurethane diaphragm is best illustrated in FIG. 8A. The diaphragm 90 contains transverse retaining members 92A, 92B, 92C, and 92D which retains an oppositely disposed pair of mating hook and loop fasteners 94A, 94B, 94C, and 94D. It will be appreciated that comparable retaining members are located on the opposite side of the flexible diaphragm. Retaining members and mating hook and loop fasteners as illustrated in FIGS. 1, 8A, and 8B. It will be appreciated that the opposite section of the flexible diaphragm also contains retaining members and hook and loop members on the upper section and also oppositely disposed at the lower section approximately parallel to hook and loop fastener members 94A, 94B, 94C, and 94D and retaining members 92A, 92B, 92C, and 92D. The mating hook and loop fasteners are respectively wrapped around the vertical poles. Hook and loop fasteners 94A and 94C are wrapped around pole 40 and hook and loop fasteners 94B and 94 D are wrapped around pole 44. The lower hook and loop fasteners on the diaphragm such as fastener members 92A is illustrated in FIG. 1. The diaphragm contains a pair of lower affixed connection members 161 and 162 to which lower one-way exit valves 151 and 152 are respectively threadedly connected which then connect to longitudinal pipes 20, 22, and 24. It is within the scope of the present invention to have a multiple number of valve connections exiting flexible diaphragm 90 to a multiple number of longitudinal pipes.
Referring to FIG. 8B, upper one-way intake valves 121 and 122 are threadedly connected to connection members 131 and 132 which are respectively affixed and fluidly connected to the upper diaphragm threaded connectors 141 and 142 of flexible diaphragm 90. By way of example, the one-way intake valves can be 4′′ in diameter and reduced to a 11⁄2′′ diameter pipe which is threadedly affixed to the respective threaded members of the upper one-way valve receiving members. Similarly, at the lower end of the diaphragm there are one-way check valves extending through the bottom of the diaphragm so that fluid can enter the diaphragm through one-way check valves 121 and 122 and exit the diaphragm through lower check valves 151 and 152 in the diaphragm. The lower check valves extend through the diaphragm and into connecting members which fluidly connect the open ends of the lower one-way check valves into the pipes 20, 22 and 24.
In operation, the parallelogram wave energy collector 10 is affixed to the ocean floor as previously described or alternatively, is affixed to the reef of the invention as described and claimed in U.S. Pat. No. 8,517,631 for “SHORELINE EROSION MITIGATION DEVICE” issued on Aug. 27, 2013. When affixed to the reef, each plumbing pipe can be affixed to the reef when it is on dry land before the reef, plumbing pipes and parallelogram wave energy collector are floated into the water. The anchors which will anchor the reef can be set in advance. The reef is towed to the site where the pipes of the parallelogram wave energy collector will be installed onto the reef and thereafter towed out to the ocean with anchors retaining the reef to the ocean floor. The wave energy collector is affixed to the bottom of the sea bed through the anchors 200 and 210 (see FIG. 4) as previously described and the parallelogram wave energy collector 10 is initially in an erect position as shown in FIG. 1. When an incoming wave hits the parallelogram wave energy collector 10 and especially the rear plate 80, the parallelogram wave energy collector 10 rotates the direction of the shore so that the diaphragm 90 is compressed between the plates 80 and 82. It is important to note that the positioning of the upper one-way check valves 121 and 122 and the lower one-way check valves 151 and 152 are positioned so that the upper check valves are above the two plates and the lower check valves are below the two plates so that they do not become squashed when the diaphragm is compressed. As the diaphragm is compressed into the flat stage as illustrated in FIG. 7, water under pressure is forced into the pipes 20, 22 and 24 and is forced out of the respective openings 20N, 22N and 24N. The pipes are initially filled with water and therefore, the water flowing under pressure from the compressed diaphragm causes the water to exit the pipes with a force to it the rotating wheel of the water turbine. When the incoming waves hit the parallelogram wave energy collector 10, the plates 80 and 82 are caused to rotate in a direction as illustrated in FIG. 6 which is in a direction away from the shore. Again, this rotational energy causes the diaphragm 90 to be compressed and during the entire compression session, the water is fed under pressure from the one lower one-way check valves into the pipes so it continuously forces water under pressure out the openings of the pipes and into the blades of the water turbine. It will be appreciated that the motion from the waves is continuous so that the parallelogram wave energy collector 10 is rotating toward the shore and then back away from the shore, continuously generating water under pressure which enters the pipes which then exits under the pipes to hit the wheel of the water turbine to cause the wheel to continuously rotate and generate electrical energy.
The waves from the ocean to the shore are traveling in a direction of arrow A illustrated in FIGS. 1 and 7 and the waves traveling from the shore into the ocean is illustrated in the direction of arrow B as illustrated in FIGS. 1 and 6.
It will be appreciated that there are a multiplicity of wave energy collectors affixed along the length of the pipes 20, 22 and 24 in spaced apart locations so that one wave energy collector will not hit an adjacent wave energy collector but the rotation is back and forth in a continuous kinetic energy to continuously generate water into the pipes under pressure so that the water will exit the pipes in the opening and hit the rotating wheels of the water turbine to generate electricity.

FIG. 9 is a representation of the parallelogram structure as previously described where there are the four posts which are numbered 440, 442, 444 and 446 and rotate in a parallelogram-type fashion as previously discussed. The posts are initially shown in their erect condition in FIG. 10. The diaphragm is illustrated in FIG. 11 and is numbered 490. The upper one-way check valves numbered 910 and 920 on the upper section of 922 and 930 and 940 on the lower sections of the diaphragm are as previously described. In this case, the mating hook and loop fasteners are instead illustrated as collars 994, 996, 992 and 998 with the upper opening 992A, 998A, 994A and 996A shown in FIG. 12 with the upper check valves 910 and 920 also illustrated. The pie sections shown in FIG. 13 illustrate the portion of the diaphragm covered by the collars. Referring to FIGS. 9 and 12, each collar is respectively over a pipe. Pipe 994A fits over and through pipe 440, pipe 996A fits over and through pipe 444 and pipe 992A fits over and through pipe 442 and pipe 998A fits over and through pipe 996. Therefore, the diaphragm 90 is tightly retained onto the four posts 440, 442, 444 and 446 so that the diaphragm 90 is held in place during the previously discussed compression and expansion cycles to facilitate water entering and exiting the diaphragm during repetitive cycles.
Therefore, the diaphragm is retained by the pipes. The first plate which is 960 and the second plate which is 962 are affixed through the affixation members previously discussed and are illustrated with respect to front plate 996 as 1110, 1120, 1130 and 1140. It will be appreciated that there are comparable affixation members which affix the rear plate to the transverse pipes. The transverse pipes are numbered in FIG. 9 as 934 and 936 for the upper pipes and 930 and 932 for the lower pipes. Therefore, the graphic illustration shows the comparable illustration in the photographs.
FIG. 15 is a top view showing the movement of the plates and diaphragm in one direction and in the opposite direction as the wave hits the parallelogram wave energy collector 10 as previously described. FIG. 15 is also a mechanical and functional concept drawing of the side view of the parallelogram wave energy collector in the compressed state when a wave has pushed it down. This shows that the water always goes into the top valves in the direction of the arrow C shown on the right. The bars depict the compression plate and the box on the left represents the water valve with the water being forced down and out into the plumbing pipes in the direction of the arrow D on the left.
FIG. 16 shows the flotation member 972 and pipe 920 between parallelogram pipe sections 940 and 944, the flotation can be adjustable end important to assist the parallelogram wave energy collector to reload with water to rise upward in the event a reciprocating force is not present. Then with a force from either side it will act to force water into the pipe.
FIG. 17 shows a multiplicity of the wave energy collectors such as 1010, 1020, 1030 affixed in spaced apart aligned locations with the water being forced through pipes such as 920 in a direction toward the shoreline under pressure as described above. An energy collector such as 1020 will connect to a pipe such as 920 with T-shaped pipe fittings such as 1200. It is within the scope and spirit of this invention to have multiple connections from a diaphragm such as 90 to a pipe such as 920.
Therefore, the wave energy gets stronger as it moves to shore as indicated with the arrows on top as it has less water in shallow water and as described an observed in nature. The head pressure pushed out of the diaphragm must be the same or greater than in the plumbing pipes but because the wave energy will get stronger, it will function to continue to maintain a good increasing head pressure as the water moves to shore as indicated with the arrows E and F as shown in FIG. 17 in the pipes. Some resistance of existing water in the pipes will cause the flow of water to lose some head pressure but the head pressure will be regained with the next parallelogram wave energy collector cycle. The head pressure and the wave energy will travel the same way to the shore and should increase until the wave brakes or dissipates. The water pressure will continue from the last parallelogram wave energy collector to the turbines on the shore and lose some energy from the pipe resistance, but this encourages the higher pressure behind it to move through the pipe to the slightly lower pressure and the resultant water pressure is positive and retains sufficient pressure in the pipes to take the water if enough wave energy is present so that the force of the water on the turbine will enable the turbine to generate electrical energy.
Referring to FIGS. 18A, 18B, and 19, it is within the spirit and scope of this invention to have alternative embodiments for the parallelogram structure. FIGS. 18A and 18B show representations of an alternative embodiment of the parallelogram structure with a pivot location just below the vertical midpoint of the structure. FIG. 18A illustrates this embodiment to have a top section that begins to flare at the vertical midpoint and widens to the top to allow three one-way check valves to receive water into the diaphragm. Referring to FIG. 19, an alternative embodiment as represented in FIG. 18B is shown in a rotated condition after being impacted by a wave. Referring to FIGS. 20 and 21, FIG. 20 is a representation of the range of motion of the parallelogram structure at high tide and FIG. 21 is a representation of the range of motion of the parallelogram structure at low tide. These representations show the movement of the parallelogram structure during different tides. The alternative embodiments listed in FIGS. 18A and 18B will have a one diaphragm that, similar to the preferred embodiment, will have one-way check valves at the top and one-way check valves at the bottom.
The present invention is a structural device or parallelogram wave energy collector which converts wave forces from the ocean to the shoreline and the force of the receding wave away from the shoreline. This device is built around a parallelogram frame which interacts directly with the described wave energy to push it or rotate it in the direction of the force, towards or away form the shoreline and floats upward with no force. Inside the structural form are contained two spaced apart compression walls with a diaphragm contained between the two spaced apart compression walls of the parallelogram. The elastomeric diaphragm must have the proper degree of elasticity in its design and typical to be made of polyurethane. Check valves on the top of the diaphragm serve to funnel water into the diaphragm. Check valves on the bottom of the diaphragm enable the water in a compressed diaphragm to exit the diaphragm and into the pipes with head pressure resulting from the diaphragm being compressed. The parallelogram wave energy collector is attached to plumbing and a foundation strongly anchored to the sea floor. It is within the spirit and scope of this invention for a colony of several of these parallelogram wave energy collectors to be affixed to plumbing pipes at spaced apart locations along the pipes. It is also within the spirit and scope of this invention to have an alternate embodiment of parallelogram wave energy collectors that can be positioned vertically on top of each other or stacked on top of each other as shown in FIGS. 18A and 18B. The colony of the parallelogram wave energy collectors is located at various distances from the shoreline, at locations where the wave energy almost breaks and each successive parallelogram wave energy collector adds to the head pressure on the pipes until water exits the pipes and terminates to create a water force on a water turbine on shore. Alternatively to a reservoir or elevated tank as a battery to use the head pressure coming back to a turbine and with the water now going back to the ocean or to be used for some other purpose. Because inshore wave energy is in shallow water, many smaller parallelogram wave energy collector act together to best harvest the energy just off the shore.
It is also within the spirit and scope of this invention to have a secondary parallelogram frame that would attach to the structural reef hardware with a top plate that would be attached to the bottom plate of the parallelogram. Riddled poles can be connected to the side of the top plate of this intermediary parallelogram with floats on the top of these poles. This would allow the parallelogram to function efficiently with the tide. When the tide is lower the floats would lower the parallelogram and when the tide is higher it will move the device higher. This will consistently position the parallelogram into the perfect energy harvesting area. It is known that the highest energy is located just under the surface of the water and this simple idea will utilize this principle.
It is also within the spirit and scope of this invention to include a variation of the diaphragm. If the diaphragm is re-configured in a simple way to keep one side fixed to the one wall and now the other side attached to a structural panel. If this panel is hinged on the bottom in a way that allows the diaphragm to pass though the bottom of it in a way that would still allow water to pass through the bottom of this bladder. With this variation, the force on the structural panel is the same which results in a similar compression of the diaphragm.
This design will eliminate some capacity but the action is more like a classic bellow. The main advantage is the elastomeric bladder will not have to stretch as much as in the preferred embodiment. The bladder takes some of the genetic energy away from the function and so this design allows more energy to compress the diaphragm. The simple one hinge design on the diaphragm allows a more efficient compression and this variation will create more head pressure.
Of course the present invention is not intended to be restricted to any particular form or arrangement, or any specific embodiment, or any specific use, disclosed herein, since the same may be modified in various particulars or relations without departing from the spirit or scope of the claimed invention herein above shown and described of which the apparatus or method shown is intended only for illustration and disclosure of an operative embodiment and not to show all of the various forms or modifications in which this invention might be embodied or operated.
