1. Field of Invention
This application relates to a structure which encompasses a free-flow hydro-powered hydraulic ram submerged deep in a moving body of water such as an ocean current, (gulf stream), using natural motive forces of nature to drive the ram. The ram applies its hydraulic force to a resisting work load, such as forcing sea water through a membrane to remove salt. The discharge of water, after the ram power stroke, is returned to current flow by a giant water jet pump utilizing the Venturi Principle. This is comparable to draft tubes or out falls which conventional surface located turbines use to return or discharge their waste water into a tail race.
It is a new Paradigm of hydro-power generation. The potential effect of this enablement is to provide high pressure sea water flows to support reverse osmosis desalinization processes. It could power the equivalents of present day and future systems for removing salt from sea water. This enablement creates an underwater hydro-power capability, without consuming any fossil fuel or other type of non-renewable energy source and without the limitations, construction costs or adverse environmental or economic effects. There is no practical limit on the numbers of this enablement, which can be placed in ocean currents or in rivers around the Earth is unlimited to provide hydro-power for mankind for as long as the World exists.
There is an urgent need to switch from fossil fuels to those energy sources that are sustainable and non-polluting. Ocean currents flow at all depths, with the strongest usually occurring in the upper layer, which is shallow compared to the depth of the oceans. The main cause of surface currents in the open ocean is the warming of the ocean by the Sun, the rotation of the Earth and the action of the wind on the sea surface.
The Gulf Stream starts roughly where the Gulf of Mexico narrows to form a channel between Cuba and the Florida Keys. From there the current flows northeast through the Straits of Florida between the mainland and the Bahamas, flowing at a substantial speed for some 400 miles. It hits peak velocity off Miami, where the Gulf Stream is about 45 miles wide and 1,500 feet deep. There the current has reached a speed of as much as 7.75 mph in its narrow central axis. Although the peak current velocity of the Gulf Stream may at times exceed 7 mph in its narrow axis off of Miami, the most likely velocities for ram system placement is in its central axis and would most probably be between 4.75 and 6 mph.
The Gulf Stream, the Kuroshio and the Antarctic Circumpolar Current are the currents having velocities above 3 knots that flow throughout the year, the strongest currents recorded for the Gulf Stream and the Kuroshio in nautical miles per day. These speeds are equivalent to 156.5 statute miles per day (6.52 mph) for the Gulf Stream, and 133 statute miles per day (6.375 mph) for the Kuroshio. Because these speeds were determined by how far the current carried floating objects in 24 hours, they do not reflect the maximum current speeds at specific times or places. Both the Gulf Stream and the Kuroshio are currents that are driven by the Coriolis force that is produced by the earth's eastward rotation acting upon the ocean currents produced by the trade winds. Because these currents are caused by the earth's trade winds and eastward rotation, they will continue flowing through the Straits of Florida and all others for as long as our planet continues to turn on its axis.
Applicant is aware of the following U.S. patents and patent applications pertaining to water powered devices and the like. None of the citations, however, discloses a power system having the functional features or the capabilities of the present invention.
2. Prior Art
Various methods of generating power from oceans have been proposed or developed. The ones that are in a marine environment are OTEC, ebb & tide systems, wave energy. More specifically related to renewable energy sources & to the ocean environment, the following concepts & methods for generating power from oceans are current state of the art.
There are more than twenty one such patented systems on this general subject area, namely renewable energy generation from ocean waters. None of these have the same technical method as the Free Flow Hydro-Powered Hydraulic Ram.
Ebb & tide systems are also subject to geographic constraints & require investments that are too costly. Neither could wave energy systems prove to be a globally applicable efficient energy generation system, as these mostly depend on wind directions.
OTEC systems have costly requirements; such as warm water flows of 7,450 kg/sec/Mw & overall great amounts of water displacement needs. Prior art systems also require cold water pipes with large diameters (57 feet per Mw) which all add to high costs.
The Free Flow Hydro-Powered Hydraulic Ram is unlike any of these previously patented systems. All other attempts have failed to establish a basic hydraulic circuit in a totally submerged underwater environment. A generalized response can be made which clearly differentiates all of them from this patent application. It is our position that none of these referenced patents contain all of the elements listed below, which this patent clearly does possess:
The standard forms of hydraulic rams are powered by conventional sources such as fossil fuel or electrical powered pumps. The hydraulic fluids travel through the ram as a high pressure force and are part of a hydraulic circuit. This includes a storage tank from which the pump draws the hydraulic fluid to be pressurized and returned back to the reservoir. In the case of this embodiment, the ocean itself is the prime mover and reservoir.
This invention generally relates to a system of capturing energy as hydro-power from moving bodies of water in the ocean for a ram function. It is understood that energy in its many forms of applications is the basis of civilization as we know it. As such, the demand for energy is insatiable. In the present circumstances, the common source of energy is by fossil-based fuels, which are not environmentally friendly and are finite in quantity. Finding renewable, environmentally friendly sources of energy is a matter of national security.
This invention, a free-flow hydro-powered ram with its integrated water jet pump system, captures and transforms the energy of ocean currents. It uses existing technologies, natural forces of wind and gravity, and the unique molecular properties of water. When these forces and the technologies are properly employed, they enable a pressure differential to be established in an infinite pool of renewable energy. The advantage offered is the system consumes no matter. This system is portable and ready to apply hydro-power to a resisting work load. It could supply the high pressure to force sea water through a reverse osmosis membrane process to remove the salt.
Reverse osmosis is a filtration method that removes salt from seawater by applying pressure to the seawater when it is one side of a semi permeable membrane. In commercial applications, high pressure pumps supply the pressure needed to push seawater through a membrane, even as the membrane rejects the passage of salt through it. This requires a large amount of energy. Typical pressures range from 800 to 1,800 psi for seawater. The largest reverse osmosis plant (Ashkelon) in the world is in Israel. By the end of 2001, about 15,200 desalination plants were in operation or in the planning stages worldwide. Some would use the reverse osmosis process, in any case they all require great amounts of energy to operate and certainly have undesired environmental effects for the planet over time.
Our Earth is a water planet. Within the oceans are moving masses of energy as ocean spanning currents with crushing pressure, due to depth. If mastered, the benefits are incalculable. In the Straits of Florida, the Gulf Stream, a moving body of water within the Atlantic Ocean, reaches depths of 2,000 feet and moves at the rate of about 5 miles per hour.
Hydropower is measured according to the amount of power released, or energy per unit time. Most hydropower comes from a mass, flow rate and/or pressure due to weight (head) effects of elevation changes. This invention, free-flow hydro-powered hydraulic ram, when placed within an ocean current, serves as a leveraging machine to develop hydraulic energy to apply to a resisting work load.
This invention relies on (1) the incompressibility of water and its mechanical properties, and (2) natural motive forces that assure the intake of pressurized water flowing into the shrouded, cone shaped inlets of the penstock leading to the hydraulic ram itself and for the motive force of its Venturi jet pump exhaust system. Gravity and other natural forces of nature assure the intake of water into all input ports as hydrostatic pressure together with a continuous water flow as a motive force for the Venturi Principle exhausting system.
Principles of Physics Utilized in this Embodiment
Molecular energy is a property of water as stated in Pascal's Law. Its molecules are constantly moving. They slip and slide past one another even when they are at rest in their passive form. The movement of molecules in the water is molecular energy. The inexhaustible quantity of molecular energy in a body of water becomes the kinetic force which powers this enablement.
The current enters the shrouded entry ports of the system. The water flow is then increased in velocity, as its flow path (volume) is reduced in diameter.
The hydraulic ram is a lever which applies its force to pistons which in turn applies force as hydraulic power to a resisting work load. Water is in fact a machine. The ram is its fulcrum agent.
The Venturi Principle, in the form of a jet pump, addresses the exhaust function.
Bernoulli's equation states that when water flows as a streamline through a pipe with a smoothly varying constriction, the flow will gain speed while passing through the constricted area (narrow space known as a Venturi tube). This creates a vacuum. A pipe (known as an eductor) leading from the ram's central chamber to the Venturi tube will suck the water out and entrain it with water flowing thru the tube for discharge.
When placed at depth, gravity exerts pressure on every square inch of a solid's surface area of exposure. Therefore, external ambient pressure must be resolved in a submerged environment. The Venturi principle with an eductor function as a jet pump is an integral part of the invention. Its application provides for the exhausting of water back into the ambient environment. Pressures incident to the refilling intake of sea water into the compression chambers, following the power/compression stroke, are adjuncts to this discharge function;
Mechanical energy (compressed sea water is a solid and in essence is a mechanical equivalent of) from the ram's sliding pistons is the link, which applies hydraulic energy to a workload, which is suggested to be the removal of salt from sea water.
This free-flow hydro-powered hydraulic ram and Venturi jet pump system uses as its motive prime mover, a moving water mass such as an ocean current. Its purpose is to harness the kinetic energy present in moving bodies of fluid to drive the ram. The power (force) output is velocity (feet per second) times mass (weight).
Water with a fulcrum is in fact a Machine. All this system requires is a water flow force from an ocean current with a means of passing it thru the ram, with an apparatus for exhausting it back into the moving ocean current.
The untapped source of water force is ocean currents, such as the Gulf Stream and other ocean currents, due to massive water flows. The movement of water and depth (hydro-static head) present in ocean currents is self evident, as is its powerful force.
The system is housed in a water-tight structure at a depth, within a body of moving water. The system is stabilized by appropriate structural members and oriented in respect to the ocean current flow. It's associated support system is a function of dimensions and pressure/volume capabilities and the performance parameters for any application. The specifications layout must include all components shown in
The computer management control system must include sequencing programs and instrumentation sufficient to operate and maintain the system, with full consideration and inclusion afforded the requirements of specific end item applications. In brief, the system must be able to sense system conditions and sequence pressure flows thru the operating system of valves. For controlling the stroke reversal events, sensors are placed at the terminal points on the ram cylinder walls to signal when the piston is fully extended or retracted, after which a reversal of movement direction begins. This is the heart of a reciprocating engine.
The system, being robust and expandable, can be designed and fielded as standardized system packages, ranging from miniaturized power versions to unique industrial sized versions.
Component Parts
The operating environment is the currents within the ocean, which are spread across the globe, an infinite source of energy.
The hydraulic ram is placed at a depth in a water-tight structure which provides both a surface level operating platform and a working floor for the system itself. (W1) denotes the ocean surface, (D1) is the depth from the surface to the ocean floor and (W3) is the upstream current. It an irresistible force (velocity feet per second X mass or head) ready to enter and power the embodiment as a prime mover and to transform itself as hydro-power. In this form it can power any number of work processes, such as a reverse osmosis process, (R5), to remove salt from water. The current also is the motive force to power the Venturi jet pump/eductor, which returns the ram's spent water back into the currents downstream flow (W9).
Power Functions
The currents of the ocean are an infinite, ready source of kinetic energy that can be caused to flow into and by this embodiment. In doing so, they transform or release energy for beneficial use of productive work processes.
The inlet “A” of the ram is shaped as a cone (P1) which increases the velocity of the flow as it exits the cone and enters the penstock in transit to the ram cylinder chambers. The mass (weight) of the flow is a function of the head pressure (H1) at the point of entry into the ram's chambers. The inlet of “B” functions in the same manner as the motive power of the jet pump.
These properties (velocity change and head pressure) determine the pressure level which powers the pistons of the ram and jet pump.
The ram's piston surface areas further act as force multiplication factors. The ram has two (R$) hydraulic outputs to service an (R5) end user workload. The spent water is discharged into the (J1) Venturi jet pump/eductor for return to the downstream current flow.
The ram's power stroke chamber forces the water in its compression chambers to exit as a high pressure flow for use by any work process which offers its resistance, in the suggested usage it would apply pressure against a membrane in a reverse osmosis process.
The Operational Phases of the Device
FIGS. 3,4 and 5 demonstrate the operational phases of the device. All numeric notations are the same in each of the figures.
With regard to
(H1) is the directional indicator of hydrostatic water pressure head which would overlie the enablement when submerged in a body of water.
(W3) represents the upstream flowing water current which surrounds and powers the enablement, its hydraulic ram component and the venture/eductor assembly.
(P1) represents the shrouded entrance port for the pen stock and the (E2) entry port for the high pressure water flow which is used as the operating power source for the (R1) ram and the (E1) Venturi jet pump. (P1) of the penstock may also be directly attached as an option to (W8) conduit which provides the water for refilling the chambers for reversing of the piston cycle.
(W5) is an in line filter used to screen out impurities and keep out debris from fouling the valves and ports of the hydraulic cylinder.
(W6) is a master on/off gate valve of the pen stock which denies or permits the pressurized water force access to the central chamber of the hydraulic cylinder. A counter-part is the master gate valve (WS) which has the same function for the (E4) suction tube of the venture exhaust component, which drains waste water from the central chamber. The opening and closing of valves sequences are controlled by (C3) sensors using a software program. (C1) is the computerized master controller for the synchronizing the strokes of the system.
(W7) is the master on/off gate valve for opening and closing the flow of water through the conduits (W8) to resupply entry ports of the ram (R3) compression chambers.
(W9) is the downstream water flow which has passed the enablement by and is moving the water discharged from the jet nozzle exit port (E6) away with it.
(W8) The conduits which feed the flow of pressurized water into the (R3) fixed conduit sliding ram piston chambers. The inflow of water refills the compression chamber and returns the pistons to their starting point in the (R3) compression chambers for the power stroke of the ram to restart.
(C1) is the electronic control process director which opens and closes solenoid controlled valves (W6, W7 and WS) regulating entry/exit ports for the components of the ram and the jet pump exhausting system.
(C2) is the electrical harness for linking piston (C3) positioning sensors to the (C1) process control director for relay/signal to solenoid controlled gate valves to open/close ports whenever the (R2) sliding ram pistons have reached terminal points in the (R1) ram cylinder. The (C1) signal to the respective valve combinations reverses the reciprocating action for the sliding ram pistons. This is analogous to the four cycle engine pattern but it is achieved by the ram & the jet pump by means of electronic timing control sequences.
(C3) The piston position sensors signals when the piston is in proximity to the sensor. The sensor signals the process control to open/close the combination of valves, thus reversing the direction by permitting the water mass (force) to engage different piston surface areas and to be discharged through the Venturi system. Sensors are located on both sides of the (R1) ram cylinder.
(R1) is a hydraulic ram cylinder with entry/exit ports, comprising a central power chamber and two end compression chambers.
(R2) is the sliding ram cylinder pistons which move back and forth within each sectional chamber resulting in increasing and/or decreasing chamber volumes.
(R3) are compression chambers.
(R4) are pressurized hydraulic energy system exit points. The hydraulic ram enablement is a circuit which transforms raw water energy from a flowing motive force into hydro-power, a near perfect from of energy. At exit points, it is available to feed an end item user. At the point of exit, there is a one way check valve which prevents a backflow into the ram's chamber. In this case, it is suggested to be a reverse osmosis system for removing salt from water.
(R5) indicates the power is fed into a desalinization process to remove salt from water by reverse osmosis. Since each input of highly pressurized sea water of the ram's power stroke comes to a stop, and begins to recycle or reset, it becomes necessary to have a second ram unit pick up the load and maintain a continuous pressure flow into the desalinization process. Therefore, there must be a plurality of ram units operating in sequenced unison to maintain a constant pressure force being applied to the osmotic membrane;
(E1) is the Venturi principle back pressure exhaust system for removing water flow from the chambers of the hydraulic ram cylinder.
(E2) is the shrouded entrance port for entry of the water mass into the Venturi back pressure exhaust system.
(E3) is the smooth pipe which is the first section of the Venturi exhaust system.
(E4) is a Vacuum (draft) tube which drains the central chamber into the Venturi back pressure exhaust system.
(WS) is the solenoid switched gate valve which opens/closes to permit water to drain from the central chamber of the hydraulic ram cylinder.
(E5) is the smooth pipe section of the Venturi exhaust system.
(E6) The exits section of the Venturi exhaust system terminating with a jet nozzle (if required) for ejecting the water mass back into the ambient flowing mass environment.
(E7) is the area near the mouth of the jet nozzle experiencing a vortex/turbulence space with a lowered pressure differential. The disturbance in part, is caused by the water mass flowing along the external surface of the jet nozzle, which is a form of resistance impeding its path of flow. This event facilitates the entry of motive and entrained drainage water into the continuous flowing water mass.
The hydrostatic paradox is the power of water to be pressurized;
Let A B C D be a closed vessel, with a small hole O on the top, in which a narrow tube T is screwed, water tight. Let the vessel A B C D be filled with water W. The pressure on the bottom C D will be equal to the weight of a column of water whose base would be equal to the area of the bottom C D, and whose height would be T M; that is, it would be equal to the quantity of water W, which would fill a vessel whose base is C D, having perpendicular sides D E and C F, and whose height is D E;
However shallow the vessel A B C D, and however narrow the tube T O, an indefinitely small quantity of water may be made to produce a pressure on the bottom of the vessel which it contains, equal to the weight of any quantity of water, however great. The pressure depends only on the depth of D C below the level of the water in the tube T O.
When an exhausting syringe is inserted into a body of water and it intakes water, one of the chambers volume increases and the opposite chamber volume decreases;
The syringe is cylinder P having a solid piston moving air tight in it. Let C be a tube proceeding from its upper side, furnished with a stopcock C and let B be another tube furnished with stopcock D. Let tube C be inserted into a body of water W under ambient pressure. If the piston then be raised in cylinder, the cock C being open, the water W will under ambient pressure will rise so as to fill the enlarged space provided by raising the piston. When the piston is brought to the top of the cylinder, let cock C be closed and cock D be opened. By lowering the piston the water W will be expelled as the space is decreased.
The double acting ram cylinder, in
The Venturi tube is based on the long known theorem of Bernoulli, in that a liquid flowing from left to right between A and B that the velocity increases and the pressure correspondingly decreases. There is a simple relationship which exists, as volume falls, the velocity increases and that as it moves from B to C the volume increases and the velocity decreases. The velocity at point B can produce a vacuum which is the basis for the eductor suction function of
Pumps employing the jet-pump principle, long known, are as follows, the jet drags the surrounding liquid along with it causing a reduction of pressure beyond ‘the nozzle and in the suction pipe sufficient to raise water from a sump or source. This principle in practical form was reported based on experiments in 1853.
As shown in
In this enablement, the motive force accelerates as kinetic energy velocity and entrains a second water stream sucked as waste water drainage from the chambers of the ram. As the chamber volumes in the ram cylinder decrease, the water being expelled is drained as a secondary water stream into the jet pump. This secondary stream is mixed with the primary (motive) stream and then through E5 and discharged as combined stream outside the system. As shown in
The discharged stream has lost part of its energy due to encountering the secondary stream and continuing as a combined stream. But it must be known that the pressure at the exit point is largely determined by the ratio (volume) of the two streams. Since the primary stream is not constrained in terms of force, being vast, it can have a favorable ratio in respect to the volume of the secondary stream. This ratio advantage, which can be as large as required, is not the ordinary case for fossil-fuel based prime movers which have economy/efficiency constraints;
This invention is in all respects a linear hydraulic motor which can perform all four-cycle engine functions simultaneously. The preferred embodiment, when placed and operated at a depth, within a body of water, is in fact, an infinite molecular power source.
To begin, the hydro-power hydraulic ram (
The water flow passes thru the shrouded input port and flows through the inline replaceable filter and fills the conduit until it applies its restrained, force against the (S1) closed solenoid switched valve which control entry or denial into the ports of the three (3) chambers. One (C1) port opens into the central chamber of the ram cylinder. This is the power stroke chamber.
The ram cylinder contains two pistons within the end chamber of the hydraulic ram cylinder. The pistons act as pressure intensifier, positive displacement forcing pumps. The interior surface areas of the pistons in each chamber determine the flow and gallons per minute of highly pressurized water expelled out of the system for end user applications.
A port, being on end of (R3, fixed conduit, refilling of water from within the motive power source. The force of the water mass then bears on the respective interior piston surfaces and moves the pistons back to its power stroke starting position.
The reciprocating action of the double acting hydraulic ram cylinder is made possible by three chambers, which divides the ram cylinder body. There are two sliding ram pistons which serve as intensified placement water pumps. As the water force enters the central chamber it presses on and moves the two pistons forward and over the (R3), fixed conduits. After the power stroke, the water in the chambers of the ram cylinder are increasing in volume as the other opposing side decreases. The water in the decreasing chamber side, in response drain out to make room for return of the pistons to their power stroke starting position.
This invention uses the Venturi Principle method to drain the chambers of the ram cylinder following the power stroke.
This is how the Eductor pipe drains the decreasing volume chambers after a power stroke. The pipe (E5) beyond the constricted area is normal size, so the flow returns to about it original speed and pressure before exiting the pipe. The embodiment has a continuous stream (A2) of water running through it at all times as a motive power source.
The water flow passes thru the Venturi pipe exhausting system with a partial vacuum present in the educator pipe (E4) as it passes the Venturi constriction and out thru the jet nozzle (E6). At the same time a flow (W3) is also moving along the outer (external) surfaces of the total system. The ambient area in the vicinity of the Venturi jet nozzle exit point is in a vortex state with a lower pressure differential in the immediate front (E7) of the jet nozzle. The stream of water from the exhausting system exits and blends with the ambient flowing water stream pump chambers.
Downstream as the pipe regains its normal size, the pressure drops to a lower pressure level then when it first entered the pipe at (E2), entry port. The pipe when fitted with a tapered nozzle (E6) produces a jet stream with downstream cavitations with effects immediately in front of the jet discharge point. This facilitates the reentry of the drainage water into the ambient water mass flowing by the discharge vicinity.
The Venturi/Eductor assembly, as the ram's integral exhausting system, is equivalent to the suction side of the typical fossil fuel powered prime mover found in millions of ordinary hydraulic circuits, which are typical linear motors. Drainage water is discharged thru a jet nozzle in the exit portion of the Venturi exhaust pipe into the outside body of water flowing past outside the discharge point. The jet stream produces a turbulence area, or vortex area of cavitations.
The electronic process control director is connected above the water surface to an external power supply and is energized. The solenoid switching valves are either in a closed or opened position for all entry/exit ports. There are six (6) valves, one (1) which move the pistons from right to left as a stroke, by changing the direction of the water flow. This movement pattern is the heart of a reciprocating engine. This water powered engine does all four acts (functions) of a fossil-based four cycle engine: intake, compress, power and exhaust. Only it does so at great volume without consuming any matter in a total friendly way to the planet.
This invention is practical and operates in an environmentally friendly way of delivering hydraulic energy. In the preferred embodiment it can provide a hydraulic force at any desired intensity level and volume. The intensity level and volume of output is determined by the diameter of the ram cylinder body and ratio of the pistons cross sectional areas differences. Also the total flow rate of the output is simply a matter of attaching additional positive displacement pumps, as integral parts of a total system.
The system uses a Venturi/Eductor exhausting system. The process is managed by electronic sensors and solenoid switched valves to open/close the entry/exit ports. The pistons move back and forth in their chambers with the sensors signaling the cadence.
This invention is practical and operates in an environmentally friendly way of delivering hydraulic energy. In the preferred embodiment it can provide a hydraulic force at any desired intensity level and volume. The intensity level and volume of output is determined by the ratio of the pistons cross sectional areas differences. The system is portable and can be greatly expanded for increased volumes and pressure levels. The system can perform the work output of conventional fossil fuel powered prime movers. The difference is its prime mover is natural forces and its operation is completely environmental friendly.

This Invention is the equivalent of a four cycle engine powered by the natural forces (W2 & W3) of the earth, an infinite source of renewable energy. It does not consume matter. It transforms energy states.
In the preferred embodiment, the hydraulic ram is immersed in an overlying body of water. The (W2) hydrostatic head is further increased as a force by the velocity of the upstream (W3) flowing current entering the shrouded entry port (W4). The pistons within the two end chambers react to this force as a functioning unit i.e. thereby transforming energy to a workload external to the ram itself. The force entering the shrouded port (W4), since liquids are not kinetic as is a gas, proceeds via the ram as a leveraging fulcrum, then onward externally by a fixed conduit to encounter or impress its force against an opposing resistance. It could be an energy cell (accumulator) or a hydraulic cylinder (rotary motor) which in turn drives an electrical generator or other machine.
The water force enters the system at a single (W4) shrouded port oriented to receive the pressurized head of water (W2) with the downstream velocity of the (W3) water force flow. A conduit routes the water force to three (3) entry ports opening into the three chambered sections of the ram cylinder body. The conduit has a (W5) filter and a (W5) master solenoid controlled valve which regulates further entry farther into the system. It functions as start/stop (opened or closed) control. It remains open at all times during the system's operating mode.
The three (3) ports for entry by (W4) water force are opened/closed by (S1), a solenoid switched valve. This valve can only be in an opened or closed state. The position of the valve determines the direction to be taken by the sliding ram pistons. By switching pairs of entry ports the pistons reciprocate back and forth, either resulting in a power output or one filling with water for a repeated stroke.
This enablement as a system is a double acting hydraulic ram. The ram cylinder (R1) has two interior walls, which separate three separate chambers. This cylinder applies a (W2 & W3) water force to the two (R2) sliding pistons, in effect being positive displacement pumps on the end of the ram cylinder body.
The (R1) ram cylinder acts as a fulcrum with (W4) water pressure acing force on a long lever pushing two pistons, displacing a pressurized hydraulic energy stream into a fixed conduits associated with a resisting force, thus driving/activating a work output. The (H4) cylinder rod applies mechanical force to all (H3) pistons.
The hydraulic (H1) cylinder converts water pressure into mechanical energy by driving two (R2) pistons in a displacing action within chambers at the end of the ram. The expelled hydraulic force leaves both ends of the ram via two (2) exit ports (R4). Solenoid switched valve (S2) open and closes the ports as necessary for the proper operation.
The water in a pump chamber, when urged forward by a sliding piston (R2), applies hydraulic energy, (pounds per square inch), to any resisting object it encounters upon exiting the pump body at an exit port (R4). This hydropower could be used to direct drive a hydraulic pump, a rotary motor, or stored in an energy cell or an accumulator. A rotary motor, with an energy cell could act as an intermediary power source if needed and could drive an electrical generator. These items are not shown because they are clearly understood and self evident to individuals skilled in the art of hydraulics.
The sliding cylinder pistons (R2) can multiply the hydraulic pressure (pounds per square inch) transferred by the power stroke. In this case, as the pressure is increased, the volume of water expelled is decreased. The ratio of the smaller interior piston areas to the larger exterior piston area is the force multiplier.
The critical spent water exhaust function is achieved by a drainage system using the Venturi Principle (E2,3,1,4 & 5) with the motive power force supplied by the flowing (A2) water mass, together with an Eductor assembly (E1) with control valve (S3) The suction system being switched on and off by master control valve (WS).
Since water, being incompressible, occupies much of a cylinder's three (3) chambers following a power stroke, it must be removed partially, before another power stroke can begin in the opposite direction. A Venturi Principle pipe (E1) and eductor pipes (E4) are used to suction the water from the chambers and to discharge it outside the system where it merges with the passing water flow (W3, E7 & W7). Removal ahead of the reversing stroke prevents back pressure resistance within the chambers as they are decreased in volume.
The Venturi assembly (E1) is a tube or pipe, with its entrainment chamber, permits the (A2) water mass to flow thru it continuously as a motive power source. The motive power flow (A2) enters a shrouded entry port (E2). This creates suction in (E4) eductor conduits which are connected to the cylinder and the tube (E1) where the drainage from the cylinder chamber is mixed into the (A2) motive power stream of flowing water.
The area (E7) in front of the mouth of the jet nozzle experiences a vortex/turbulence space with a lowered pressure differential. The turbulence is caused by efflux from the jet nozzle (E6) and the water current (W3 & W7) flowing across the external surface of the Venturi pipe (E3 & E4) which is a form of resistance impeding its path of flow. This event, arising in the external flowing energy systems water mass facilitates the reentry of water exiting the exhaust system of this embodiment. This completes a hydraulic circuit, although unconventional in method by this enablement. The usual circuit has a holding tank from which its prime mover suctions the fluid for circuit recycling.
This enablement, comprising two (2) reciprocating pistons is managed by an electronic controller director (C1) with its interrelated wiring network (C2) which handles signals from piston positioning sensors (C3) at stroke terminal points to activate two (2) solenoid controlled valves (WS and W6). These valves regulate the reciprocating functions of the total system.
A signal that a piston is at a terminal stroke point in will energize the valve to move to on/off positions, thus reversing the flow into or out of parts. The open or closed state for each valve depends on which direction, right or left, the power or refilling/drainage stroke is to move.
Software programs and hardware, as in components (C1, C2 & C3) are readily available prior art from commercial suppliers to the hydraulic actuator trade who design and produce for specific applications.
The system has three master control valves responding to an electronic command to open or close. They deny or permit the water to enter or exit the system. The purpose is to control the operating mode of this enablement by automation.
In summary this enablement has as its prime mover, an infinite renewable energy source, the currents of the ocean. It consumes no matter as it transforms hydro-kinetic energy into usable hydro-power. It is readily replicated; there are endless locations for its placement across the globe. These are advantages over all fossil-based systems in present use. This invention as a source of available unlimited hydro-power, as such it offers the World a better method of removing salt from water. Potable water, a basic need for human life, can be produced without further harming man's environment on this planet.
