Abstract:
The subject of this invention is a hydraulic compressor that uses the clean and renewable energy of any flow of any waterway having a difference in height between the water intake and the water discharge, in order to admit and compress air in the said hydraulic compressor without doing any damage to the environment. It uses water pressure to compress air in a pipe and the compressed air is collected in a pressure tank to be used later to run a power plant such as that described in CA patent no 2328580.

Description:
[0001]     This invention relates to the construction of a hydraulic compressor that uses renewable energy.  
         [0002]     The subject of this invention is a hydraulic-like compressor; that uses the clean and renewable energy of any flow of any waterway having a difference in height between two points along the waterway in order to utilize the potential energy of water to compress air in the said hydraulic compressor. It uses a pipe that replaces the cylinder, and water that replaces the piston of compressors, and it eliminates the use of non-renewable energy while ensuring ease of operation, efficiency and the conservation of energy.  
         [0003]     The embodiment of this invention includes the following:  
         [0004]     1—A water line that brings the water of a stream, a river, a dam, etc. from a high point to the hydraulic compressor, as long as a difference in height exists in the water-way that permits the water to flow by gravity. The water-line has an inlet and an outlet. The inlet is located at an upstream of the water supply, and the outlet is located at a downstream of the water supply.  
         [0005]     2—A main valve connected to outlet of said water-line to control the flow of water supplied by the water-line into and out of water-line called the line-cylinder.  
         [0006]     3—A line-cylinder having an inlet and an outlet connected to the main valve that controls the water admission in order to compress air, and the water discharge that occurs at the end of the exhaust of compressed air to allow atmospheric air to enter the line-cylinder. The exhaust of compressed air and the admission of atmospheric air are done through air inlet and outlet valves that are located at a higher point then that of the water inlet and outlet.  
         [0007]     4—An air pressure regulator that is installed between the outlet air valve and the air tank of the power plant of the Canadian patent no 2328580, at the height where the value of the hydrostatic pressure of the column of water is equal to the pressure needed to open the said pressure regulator, in order to produce the right compressed air needed for the good functioning of the said power plant, while eliminating the dead volume inside the Line-Cylinder, where the air can be compressed and not pushed out of the compressor.  
         [0008]     9—A control circuit to control the operation of the main valve, in order to ensure o good functioning of said hydraulic compressor by allowing atmospheric air to enter the line-cylinder, and compressed air to exit said line-cylinder at the right time.  
         [0009]     The length of the line-cylinder can have variable dimensions requiring always an ascending slope in order to permit a full exhaust of all the compressed air of the same stroke.  
         [0010]     The water-intake line that brings the water to the compressor, and the Line-Cylinder where the air is compressed can be buried in the ground without affecting the functioning of the said hydraulic compressor, while leaving the soil for the agriculture or for other uses.  
         [0011]     The compressed air produced by this type of hydraulic compressors will be used to run power plants of the sort of the Canadian patent no 2328580, with no need to build new dams that flood big areas, however we can still use the dammed water of the existing dams to run the hydraulic compressor of the present invention.  
         [0000]     The Other Aspect of this Invention is:  
         [0012]     The Lines-Cylinders of this hydraulic compressor of the present invention can be replaced by water reservoirs that can contain bigger flow of water in order to compress a bigger volume of air at a higher discharge pressure, because of the big bases and the lower heights of the said reservoirs that give a bigger hydrostatic pressure which is the consequence of the difference in height between the water intake at the highest level of the water-way, and the higher level the water can rich inside the reservoirs.  
         [0013]     Depending on site specifications and the output required, various components, configurations and dimensions for the embodiment may be combined to achieve the desired results. For a better understanding of this invention and to facilitate its examination, it is represented in the following 20 Figures.

         [0044]     It should be understood, of course, that this compressor can be built from various materials and in different dimensions according to the quantity of compressed air required. The drawings do not show every step in the construction of the present invention, but they set out the overall result clearly.  
         [0045]     According to the example of the present invention, the hydraulic compressor has two Lines-Cylinders, and before starting it, all of its components must be in place in order to produce compressed air.  
         [0046]     1—First the location of the hydraulic compressor is chosen in order to determine the distance between the highest level for the water intake of the said compressor and the lowest level for the water discharge, that helps to locate the pressure regulator and to determine the discharge compressed air pressure, in order to build the appropriate power plant of the Canadian patent no 2328580 that can function with the actual compressed air of the said hydraulic compressor.  
         [0047]     2—The water line  1  will be in place in order to transit the water from the water intake at level  29 , to level  28  where the main valves are installed.  
         [0048]     3—The main valve  2  will be in place to connect from one side the water line  1 , and from the other side the Line-Cylinder  6 . In addition the water line  18  will be in place to transit the discharged water after every compression stroke through the main valve  2  to the water-way  7 . Equally the main valve  2 -A will be in place to connect from one side the water line  1 , and from the other side the Line-Cylinder  6 -A. In addition the water line  18 -A will be in place to transit the discharged water after every compression stroke through the main valve  2 -A to the water-Way  7 .  
         [0049]     4—The Lines-Cylinders  6  and  6 -A will be in place in an ascending position that permits to the water to compress and discharge toward the air tank  25 -A all of the admitted air inside the compressor.  
         [0050]     5—the air tank  25 -A will be in place to receive the compressed air from the hydraulic compressor the subject of the present invention through the air outlet valve  23 , the pressure regulator  24 -A, the check valve  24  and the air line  25 .  
         [0051]     6—the power plant of the Canadian patent 2328580 will be in place to receive the compressed air through the air line  21 .  
         [0000]     Operation of the Invention.  
         [0052]     The said hydraulic compressor can have any number of line-cylinders that work according to the same method. The following is the functioning of line-cylinder  6  as an example:  
         [0053]     1—Once all the components are in place, the hydraulic compressor is ready to run.  
         [0054]     2—A first role of the radial boring  17  of the mobile part  14  of the main valve  2  is fulfilled when the said radial boring  17  gets in line with the two borings  15  of the stationary part  13  of the main valve  2 , to let water coming from the source by line  1  to enter the line-cylinder  6  of the compressor, in order to compress the imprisoned air, while the communication between the Line-Cylinder  6  at its lower level and the waterway  7  through the two borings  16 , is blocked by the same mobile part  14  of the main valve  2 .  
         [0055]     3—Considering that the boring  17  of the mobile part  14  is communicating between the borings  15  of the stationary part  13  of the main valve  2 , we open the gate that lets the water in the first water line  1  and then to the Line-Cylinder  6  through the main valve  2  to compress the existing air.  
         [0056]     4—The water starts rising in the Line-Cylinder  6  while compressing the imprisoned air and forcing it to go to the air tank  25 -A through the outlet valve  23 , the pressure regulator  24 -A, the check valve  24  and the air line  25  that connects the compressor to the air tank  25 -A.  
         [0057]     5—When the water arrives at the highest permitted level  26  inside the Line-Cylinder  6  where the pressure regulator  24 -A is placed, it sets on the electrical contactor  10  that connects the electrical power to a first circuit breaker in order to start the motor  3  that starts turning the mobile part  14  of the above-mentioned main valve  2  in one direction.  
         [0058]     6—When the motor  3  starts turning the mobile part  14  of the main valve  2  in one direction, in order to close the water inlet passage between the borings  15  that stops by this move the air compression, and opens partially little time later the water outlet passage, between the borings  16  that exits the water from the line-cylinder  6  toward the waterway  7 . When the motor  3  of the main valve  2  arrives at the end of its run in the actual direction, and after the water discharge passage is completely open, the contactor  11  will be set off in order to cut the electrical power from a circuit breaker that stops the motor in order to give time to complete the water discharge toward the waterway  7 .  
         [0059]     7—A second role of the radial boring  17  of the mobile part  14  was fulfilled when this radial boring  17  got in line with the borings  16  of the same stationary part  13  that has the first boring communicating with the Line-Cylinder  6  at its lower level, and the second boring communicating with the waterway  7 , in order to facilitate the water discharge after the exhaust of the compressed air of every cycle.  
         [0060]     8—The depression created during the water discharge inside the Line-Cylinder  6 , closes the compressed air outlet valve  23 , and opens the air inlet valve  22  in order to replace the water by atmospheric air.  
         [0061]     9—When the water stops flowing out of the compressor to the waterway  7 , the contactor  20  connects the electrical power to a second circuit breaker that connects the electrical current to the motor  3  of the main valve  2  that gives the following results: 
        A—In the beginning of the same run that was travelled in the other direction, the blockage of the outlet passage of the water is ensured when the boring  17  of the mobile part  14  of the main valve  2  cuts off the communication between the lower level of the Line-Cylinder  6  and the exterior of the compressor. While continuing to turn the mobile part  14 , the boring  17  realises the communication between the source of the water and the inside of the compressor namely the interior of the Line-cylinder  6  through line  1 , that starts a new compression stroke.     B—At the end of the run of the said mobile part  14  of the main valve  2  in the actual direction, the contactor  12  is set off in order to stop the motor of the main valve. By now the compressor is ready for the next cycle.     C—As the contactor  10  is off, the water keeps flowing and rising in the compressor while compressing and pushing out of the said compressor the imprisoned air, until it reaches again the highest permitted level  26  inside the Line-Cylinder  6 , where it sets on the contactor  10  in order to turn on the motor of the main valve  2 , that starts another working cycle for the hydraulic compressor, and so on.        
 
         [0065]     According to the example of the present invention, the compressor has two Lines-Cylinders  6  and  6 -A. Hence the second main valve  2 -A of the second Line-Cylinder  6 -A will be activated by a second electrical motor  3 -A that is supplied in a parallel way with the first motor  3  of the first Line-Cylinder  6 , by the same electrical circuit, but the cycles will be inversed, that means:  
         [0066]     When there is water admission in the first Line-Cylinder  6 , it will be water discharge from the second Line-Cylinder  6 -A to the water-way, that means air compression in the Line-Cylinder  6  and air inlet in the Line-Cylinder  6 -, and vice versa. Only one electrical circuit is needed to operate the electrical motors of the compressor&#39;s main valves of the same compressor, but the contactors and the circuit breakers of only one Line-Cylinder are used in order to facilitate the operation of the said hydraulic compressor the subject of the present invention.  
         [0067]     In summary, the main advantage of this invention is to produce compressed air in an effective way through the use of the renewable energy of any waterway, in order to supply especially any location in remote areas where the power is in need. At a condition to have water flowing with a difference in heights between the water intake and the water discharge of the said hydraulic compressor the subject of the present invention. We knew that in raining time many places have flowing waterways! 
         [0068]     It should be understood, of course, that the foregoing disclosure relates to only a preferred embodiment of the invention, and that it is intended to cover all changes, and modifications of the example of the invention herein chosen, for the purposes of the disclosure, which do not constitute departures from the spirit and scope of the invention.
