   TECHNICAL FIELD 
   This text refers to the following invention, which is an electric-electronic mechanic mechanism component setup, which allows for the best fluid compressor performance (gas, air, oil, water, or other types of fluids), there are so many advantages compared to the current technology for compressors. 
   The current refrigeration technology applies to diverse processes, such as: compressing and expanding refrigeration gas, nitrogen cylinder, Peltier cells, etc . This invention, which this patent is for, makes it possible to make great progress in the first process (which is, compressing and expanding fluids). 
   BACKGROUND 
   Refrigeration technology through compression and expansion of refrigeration gas and compression of fluid by means of piston movement within the cylinder that uses an electrical motor propulsion force is relatively old-fashioned. Moreover recently, propulsion force without the use of an electric motor; as the motor has been substituted by a solenoid coil that propels the piston forming a fluid compression chamber at “one” of its extremities. 
   DISCLOSURE OF THE INVENTION 
   One of the innovative properties of our new technology is: there has been created not just “one” but “two” compression chambers, this is “one at each piston extremity” (taking advantage of both piston” extremities, see diagram  FIG. 15 ,  FIG. 18 , and  FIG. 19 ). 
   Our great invention that uses “two” symmetric pistons, forming as such, “three compression chambers,” as one of these chambers has “double the volume” of the other two. Being that, the movement of the “two symmetric pistons” and the “harmonics”; in this manner, it is possible to “annul” the unwanted equipment set vibration. 
   The main advantages that this new technology offers are the following: the purpose of this patent request, the distinguishing characteristics are the following: 
   This compressor is much smaller, lighter, more efficient, lower electrical consumption, compresses the fluid more quickly, less vibration and noise, manufactured more quickly and in smaller quantities of raw materials. It runs on a smaller quantity of lubricating oil; therefore, it has a lower environmental impact.

   DETAILED DESCRIPTION OF THE INVENTION 
   On the attached diagrams, which are an integral part of the report, on page 1/9 it shows a perspective view of the product. Then to be more specific, it shows the possibilities of the product; for example, the horizontal cylinder in the upper part, can be multiplied by two, four, etc . perpendicularly). The outer product casing, as it is made up by joining the two symmetric shells, which can be fastened by welding or screws, being that the operating mechanism components are located on this side. These “shells” can be built out of the following raw materials: injected aluminum, reinforced plastic, resinous fiber, cast steel, or steel press-molded, ceramic, etc . 
   Pointing out more details on page 1/9,  FIG. 1  number  40  is a hollow horizontal cylinder,  41  is the cylinder cover (this cover may be screwed down or welded to the cylinder),  42  displays two holes for the fluid to enter and exit, at the other extremity (on the opposite side) there is the identical set of holes. 
   Number  43  points out the fluid inflow and outflow, the same as the opposite holes (hence, these holes are symmetrical “at the center,” which can be substituted by a pair of holes on only one side, similar to the pair of extremity holes). Either format is acceptable. 
   Number  44  displays a coupling (or “neck”), which is: the horizontal cylinder connection (or for the horizontal cylinders) the motor (traction source). Although, the traction source does not need a motor (this is optional), traction can be obtained through solenoids, installed surrounding the horizontal cylinder (according to diagram pages 4/9 and the diagrams in  FIGS. 15 ,  16 ,  17  and  18 ). 
   Continuing on Page  1 / 9 ,  FIG. 1 , Number  45  displays the electric motor (in fact, the motor is within the same casing as the compressor, but the motor housing is the same enclosed compressor casing). 
   Number  46  is the back or the lowest part. The compressor attachment to a machine structure (for instance, a refrigerator, etc . ) can be placed at the lower part of the appliance. Hence, this unveils challenging possibilities for the project designers (to foster their creativity). 
   On the diagram on page 1/9, it displays a rear diagram view of the last diagram. Whereas  FIG. 2  shows a cutaway view of the last diagram, where  50  displays the horizontal cylinder wall,  51  are the horizontal cylinder covers (there are two symmetric covers, referring to Diagram of  FIG. 6  on diagram page 2/9, where “ 6 A” is a front view,  6 C is a top view,  6 B is also a side view, but from the viewpoint of within the cylinder). 
   While still looking at diagram page 1/9,  FIG. 2 , number  52  displays the external casing wall,  53  displays the fittings (the “male-female” pins) when the “two shells” are fitted, the whole component unit is centralized, so these pins act as “guides” that lead to the “shell” stability, for welding or screwing purposes. 
   Continuing on page 1/9,  FIG. 2  number  54  displays the pistons, which locate within cylinder  1 , the articulating connecting rods  55  transfers traction to the cylinder  54 . The movement is linear and these connecting rods  55  and  56  are connected to the double crankshaft  60 , axles  59  are the motor axles, that just surround these axles with the rotor (that just surround these rotor axles) (this fitting is under pressure). Inside “shell”  62 , there is the motor stator that just fits perfectly, rubber, polyurethane, plastic, or other materials for the shims. 
   Number  63  displays the opposite articulating rod, the same as  55  and  56  (they are symmetric). 
   Number  64  is a divider that can optionally hold a retainer to protect against oil lubrication infiltration and then to keep the articulating connecting rods immersed in oil. Therefore, it is possible to choose if the oil-lubricant insulation penetrates the inner parts of the motor, so as to lubricate, cool, protect, and to increase its useful life. 
   Number  70  displays one of the compressor chambers, the same as the other extremity. Number  65  displays the other compressor chamber (so it is possible to consider this as a “central double chamber”). 
   Number  66  displays the hole for the lateral fluid inflow and outflow. 
   Number  67  displays one of the two valves that control the fluid inflow and outflow (this valve is made from flat pressed sheet metal (this is shown on page 3/9, see  FIGS. 7 -14 ). 
   Continuing on page 1/9, Number  68  is a “spacer” made of steel, polyurethane, ceramic, or other materials, which is a “cylindrical spacer pad” for the two valves, this spacer has two through holes for fluid flow (each through hole allows for a unidirectional flow). Number  69  is the other valve that serves the same purpose (symmetrical) so this is an identical valve-spacer as in the opposite extremity. 
   On diagram page 2/9,  FIG. 4  displays a “partial cutaway” view, this is pictured on page 1/9,  FIG. 2 , whereas in  FIG. 3 , E and C display the cylinder extremities. 
   Another detail on page 2/9  FIG. 5  displays the valve with a hole and a slit; this last mentioned detail forms a fin (or latch).  FIG. 6  displays three cover views. 
   On pages 2/9,  FIG. 5  displays a front view of the unidirectional valve, whereas  70  is a hole for unrestricted fluid flow and  71  shows a metallic plate (or strip), which curves by means of the fluid pressure. 
   Another detail on page is 3/9,  FIGS. 7-14  this displays another valve model, which can be called “CURVED VALVE,” which is previously curved (or slightly flared), this curve is shown as  FIG. 12 , side view (see  78 - 80 ). This curve on the plate is for reducing the noise that comes from the “intermittent knocking” from the plate onto the base (opening and closing the fluid flow intermittently), this noise is similar to a buzzer. The main principal is similar to any flat plate that may be made of (metal, paper, cardboard, etc . ), that if it is knocked against any surface it makes noise (from knocking on the surface of a table), however if it is curved, then it meets the surface silently (therefore, the “mechanical” noise is eliminated, so you can say that the plate does not go straight down, but instead it “unrolls”). 
     FIG. 10  shows a “ring absorber,” made out of thin sheet that is fit into the spacer (valve base) around hole  84 , to be more exact at hole  85  (see  FIG. 11 , that shows a cutaway view of the “spacer,” which is the base for the valve). So, when the valve goes down, it first touches this ring on part  86 , this absorbs the fall impact, thus reducing the noise. “VIEW  9 ” shows a top view of the ring absorber, whereas  87  is the fluid flow hole. 
   Another detail on diagrams is  3 / 9 ,  FIG. 11 , this shows a cutaway view of the spacer (valve base), whereas  85  displays the hole (to be more exact only a slot) for fitting in the absorber ring (see  FIG. 10 ,  85  is the controlling fluid flow hole,  88  shows another fluid flow hole and this one is for controlling the fluid flow commanded by the other valve (symmetric, the same spacer), and  89  display the optional surface base curve depression. 
   Another drawing on page 3/9 is  FIG. 13 , this shows another silent valve model, where the plate is “flat” (or “straight”), but the base is curved (or convex, or it could even be the opposite of a “depression,” which is “concave,” according to the designer&#39;s choice).  96  displays the “spacer” (or the valve body base) and  91  and  92  are the fluid flow holes.  93  displays the “flat plate” (called the “valve fin”),  94  is the fin base,  95  is its body, or attachment extension.  96  display the convex base, hole  91  also including convex brackets for fitting the plate, as the fluid pressure will bend the plate, therefore radius  93  must fit the bent curvature, this curvature depends on the plate thickness, the kind of material, its resistance, hardness, etc . 
   Another detail on diagram page 3/9 if  FIG. 14  that shows the piston extremity, there is a depression (or cavity) in the same shape as the valve, this is for reducing the “accumulated fluid” leakage (this is: The small amount of fluid that remains in the compression chamber, and this could not be expelled, just the amount is reduced).  98  shows the cavity that has already been mentioned,  99  is the piston body,  100  and  101  is its extremity.  102  shows the part of the cavity that cannot be displayed on this diagram, as this diagram is drawn in a perspective manner. 
   On diagram page 4/9,  FIG. 15  displays the compressor set without any motor. This project mode is based on the motor-less traction as the traction in this case comes from the solenoid coils. Shown as numbers  105  and  106  are solenoid coils, which means that the ferromagnetic core  107 , spacer  108  is moved by a magnetic force generated from the solenoid coils. Therefore the two coils (which are placed at opposite ends at a total of four solenoid coils, see  FIG. 18  and  FIG. 19  on this page 4/9) advance and retract the piston intermittently (or three coils options). Although, optionally, there may be only one coil, then the piston will retract moved by the spring movement,  109  is a spring that pulls the pistons back to their normal position. Numbers  115  and  116  display the spring stay. Number  57  is a double crankshaft. This diagram shows the string attached to the left rod (number  110 ), but it may be attached to the articulating connecting rod number  111  (this is what keeps the pistons usually retracted).  FIG. 16  displays a front view of the motor-less compressor (the same as the above mentioned, at  FIG. 15 ). See  FIG. 19 , whereas number  139  is an electrical connector so that it may house the electronic circuit (for controlling the solenoids). In  FIG. 15 , numbers  112  and  113  are the outflow and inflow fluid holes. Around axle  117 , you can install an optional “Inertial disk” (whose angular momentum can be calculated by multiplying mass x velocity, this supplies rotational motion to axle  57 ). Further on this page is  FIG. 17 , which displays a piston model (preferentially made of Teflon or nylon). These two part numbers  118  and  119  fit symmetrically, being that number  120  is the ferromagnetic core that fits inside these parts, numbers  121  and  122 , are fitted (male and female) to facilitate machining. Numbers  123  and  124  are the holes to fit the articulating connected rods. The left piston would be the same diagram; only it would be smaller (as there is no ferromagnetic core, or optionally as it could have one to make it more reinforced and stable under high pressures). 
   On diagram page 4/9,  FIGS. 18 and 19 , there are displayed a more detailed derivative technology model, where just the double crankshaft and the connecting rods (articulating) are done away with and therefore a safety ring is added (this is a soft material such as rubber, nylon, ambatex, or any other similar material), shown as number  127  ( FIG. 19 ), the purpose is to reduce any collision impact between the two pistons. Two equal polarity magnetic extremities may be placed at both ends (repellant, known as “permanent magnet” or “electro magnets”) on the piston tips (this is also for reducing the impact). Or there may be a spring placed between the two pistons (for avoiding collision impact and favor harmonic oscillatory movement). Numbers  128  and  129  display electromagnetic coils (there may also be only one coil, for each piston, the designer may choose this option using the above-mentioned spring between the two pistons), which are activated from the magnetic core  130 , piston  131 , moving linearly (back and forth). Numbers  132  and  133  display the fluid compressor chambers. Numbers  134  and  135  are non-magnetic rings (and preferably, they are electrical non-conductors), for spacing between the coils. 
   Another detail on diagram page 4/9,  FIG. 19 , number  136  displays a ring fitting for attaching coils  128  and  129 . Number  137  displays a protuberance on the cylinder wall. The main purposes are: mechanical support for the coils; and reinforcing the cylinder wall against internal mechanical pressure produced by the pressurized fluid. 
   Number  138  shows the hole for the fluid entrance and exit. 
   Number  139  shows a compartment for housing an electronic component set for controlling the coils, as well as, controlling the position sensors (that show the position of each piston), while the equipment is operating (going back and forth) these may be an inductive sensor, capacitive sensor, or others, etc. 
   This model runs the same as those that are based on the double crankshaft and connecting rods. Although, there is a need for a dependable electronic controller (this needs to be well-adjusted), and that slides almost frictionless, keeping the oscillating movement, perfectly symmetric, and unsynchronized (out of phase) to eliminate all vibration. 
   On diagram page 5/9, it displays the air compressor system, where  FIG. 20 , number  140  is a tank. 
   This is a patent request and it is also for showing the possible applications for this new technology according to the original request. The last diagrams displayed are for refrigeration or other usages), and, besides compressing fluids for refrigeration as it is lighter, smaller quantities of raw materials, takes less space, increased stability and much smaller consumed energy costs, lower manufacturing cost, greater profitability, etc.) and a combustion motor (similar to those used in automobiles and trucks). This also makes it possible to produce a new type of AIR COMPRESSOR. This product is displayed on diagram page 5/9. 
   The air compressor based on this new technology is the object of this patent request, presents many advantages regarding the present compressor technology. The compressors used nowadays are: 
   a) It uses flexible diaphragm, connected to a rotational axle by means of a simple crankshaft. 
   b) It also employs a compression piston (the same as an internal combustion engine made up of a piston, around that there are metallic piston rings for sealing and lubrication), that dislocate within a cylinder compression chamber at either end of its extremities, the same as internal combustion engines (or combustion chamber as in automobiles and trucks). 
   Among the main advantages for the new air compressor are:
         Decreased energy consumption (half or even more economical).   Faster air compression is performed (or compressed air), about two times greater than the speed from the old system (this means that the present-day compressor technology does not take advantage of doubling the consumed power, which now; by using our technology, it is possible to double the speed in producing the compressed air).       

   —It fills the tank, or compressed air storage much faster.
         Decreased vibration and noise (since the vibration is eliminated; or in other words it is compensated by being unsynchronized—out of phase).   Smaller size and uses less raw material to manufacture the product.   Lightweight.   —The equipment does not overheat as much.   —Uses less lubricating oil.   —There is no external motor, pulleys and drive belts, or pulley belt covers, etc .   —More user-friendly to the environment, etc .   —It makes it possible, optionally, to do away with the “lubrication sealing rings” (this depends on your project, or the needed pressure), as these may cause serious friction (generating: over-heating, energy loss, and performance, that in due process causes breakage, destruction, etc . ). Doing away with the “rings” is possible due to our piston design, cylinder shaped held at the extremities; however, the work is performed linearly but without undergoing any torsion.       

   Take a look at the attached diagrams to see further details of our project. 
   On page 5/9  FIG. 20  it shows a perspective view of our final product, in which number  140  is the reserve tank made of steel or another material, number  141  is the base that attaches to the rubber bases and the compressor (the main objective in our patent request) which is number  142 . Likewise there are numbers  144 ,  145  and  147  showing the piping, terminals and pipe connections for the inflow or outflow of the pressurized fluid. Number  148  displays the lateral inlet/outlet for the fluid (the same as number  144 ), however number  148  does not show any connected piping, just for better visibility (to not overload the diagram). 
   Naturally, there may be some changes in the diagram, or mere technical improvements. Number  149  shows the bases (one pair), or the support bases, for complete machinery stability. It is also possible to build a self-contained unit, which is portable and may be used for non-professional applications (such as for hobbies and do-it-yourself jobs). 
   The diagram shown on page 5/9, displays the dimensions (scale), the tank (compressed air storage tank) from  FIG. 20 , these are the dimensions: Diameter=30 cm., length=54 cm, the length of the horizontal cylinder (tube) for the compressor (attached to the left extremity of the tank)=17 cm., the compressor motor diameter is=11 cm. However there can be other sizes you may wish to design and build. 
   Another detail on diagram  5 / 9 , is  FIG. 21 , that shows the drawing partially cutaway at one of its ends that is similar to the opposite side of the hollow cylinder). Number  152  displays the wall (to see the outside on  FIG. 20 , number  150 ). Continuing on page 5/9,  FIG. 21 , numbers  154 ,  155 , and  156  are the fluid inflow and outflow (regarding compressed air),  157  is the external cover wall (this is what covers the extremities, according to what was shown on the last page, there are two extremities, however there can be four, or more, depending on the number of “cylinders  150  (see FIG.  20 )” (that may be named as “pipes  1 ,” or the “sleeve  1 ”) that if necessary is placed perpendicularly). Number  158 , displays the piston that moves inside “cylinder  1 .” Number  159  displays a hole in valve “a” (this is shown as  161 ) for fluid flow, then number  166  shows a “fin” (made out of a round slit, on the same page where the valve is) the purpose of this is to control the fluid flow (blocking it in one direction and freeing it in the other). 
   Number  160  displays a “separator spacer pad” that holds the two valves (Valves and, or “a” and “b”), this spacer can be made of steel, ambatex, Nylon, polyurethane, ceramic, or other materials, however the more porous or soft the material is the lower the noise level will be). 
   Number  163  displays a “slit” or fitting on the inside of cylinder  152 , for fitting in “valve  161 ”+“spacer”+valve  162 ,” so in this way, there are two “slits  163 ,” one on each extremity of cylinder  152 . 
   Number  164  shows one of the holes on cover  157 , for fluid flow. Number  165  displays a salience on the cover to block one of the fluid outlets. In this way, the fluid is sucked in by piston  158 , it enters through hole number  156 , it goes through the inside of the salience number  155  (that is a half-moon shape and it is an extension of cover number  157 ), thereafter it goes through the inside of “spacer” number  160 , then on to fin number  166  that opens up (valve number  161 ), this fills the inside of the cylinder to form the compression chamber. After the fluid has been pressurized, it goes out through hole number  159 , then it goes through the inside of “spacer number  160 ,” then through hole number  164 , going out through outlet  155 , and into its appropriate piping connection. Notice that valve number  162  using the fin for the fluid outflow (the same as valve number  161 ). Side outlet (symmetric, described above, see page 1/9,  FIG. 1 , and number  43 , and  FIG. 2 , and number  66 ), there is also a set of valves the same as numbers  161  and  162  (if you wish to have only one lateral valve, non-symmetrical, for inflow and outflow of fluid then there are numbers  160 ,  161 ,  162 , and  165 ). 
   It is extremely important to notice that this is a completely new technological component setup, the purpose of this invention patent, especially the double crankshaft, which brings out many new possibilities to improve air compressors that applies “contraction and expansion on a flexible diaphragm” (this is generally made of rubber, or a similar material). This type of air compressor is known as a DIAPHRAGM COMPRESSOR. 
   On diagram page 5/9,  FIG. 22  displays a front view ( 1 A) and a side view ( 1 B) of a diaphragm compressor for the present technology, where number  170  shows the cylinder where the diaphragm is located,  171  and the diaphragm,  172  this is on the inside of the diaphragm (that is the air compression chamber),  174  is the channel where the shaft, or the rod that is connected to axle  175 , the motor,  176  and a base (or footing). 
   In  FIG. 23  shows “our new diaphragm compressor” that uses the double crankshaft (one of the main innovations and our patent claim) in this present patent). It can be built using two diaphragms (inverted, this is, while one is sucking in the fluid, simultaneously, the opposite side is compressing, which is one of the targets of this present patent). This way the vibration will just be reduced (increasing the frequency and decreasing the amplitude and the wave length), however, by using four diaphragms, the unwanted vibration from running this component set is then annulled (this is out of phase or in other words unsynchronized). 
     FIG. 23  (page 5/9), this diagram shows our new four-diaphragm compressor (shows  2 .A is a front view, and  2 .B is a side view), where number  184  and  185 ,  186  and  187  are diaphragm pairs (a total of four units), interconnected by means of four connected rods  180  (symmetric to the double-crankshafts displayed by  181 ). Note that at this point the diaphragms are smaller (¼ of the size, or a fourth of the diaphragm drainage size in the present day technology, in this case the motor will be smaller, half the size). The base (the footing) is displayed as  183  (in this case the fluid entrance does not take place from the bottom, but it is sealed against sucking the floor dust). However, in this model the connecting rods can be done away with (but if necessary the designer can apply this as a construction option). 
   For our diaphragm-compressor, the main advantages as when compared to the present technology, are very similar to the advantages described in the beginning of this report shown on  FIG. 23 , that displays a model with four diaphragms. However there may be two, four, eight or more. 
   In  FIG. 23 , shows “our new diaphragm compressor” that uses the double crankshaft (one of the main innovations in this present patent). Where numbers  184  and  185  are a pair of diaphragms, interconnected by means of the straight connecting rods  180  (symmetrical), number  181  shows the double crankshaft. The base (the footing) is number  183 . 
   The advantages are: Better performance (double), greater speed (double), lower vibration noise (as the two diaphragms are the noise is reduced while in the four diaphragm model the noise is completely eliminated and it is out of phase and unsynchronized). However, in this model, the articulating connecting rods can be done away with (but they can be used according to the need, for the designer this is just one more built-in feature). 
   The present standard diaphragm compressor (the present technology), exerts energy in the half—circle motor rotation for compressing the air, then in the next half-circle the motor rotation compresses the air; so then there is air suction to fill the chamber, therefore the energy consumption is much less (however, in the present-day technology, the same motor run this, the same power and the same consumption) for both half-circles, which is an efficiency loss (an analogy would be, for example: Using a “truck” to perform half the work, the same truck is used for the other half of the job that a simple motorcycle could do). Therefore in our technology, the object of our present patent, two or four diaphragms can be used, without increasing the energy consumption (better yet: just increasing the consumption a bit), even more with less total vibration for the component unit, greater performance, and a lot of other advantages gained. 
   Therefore, by using our technology, the object of this patent, two diaphragms can be utilized, without increasing the energy consumption this is the same as above. Therefore, applying our technology, the object of our present patent, it is possible to use two diaphragms, without increasing the energy consumption (in other words without increasing in any meaningful way), including less vibration in the whole component unit, greater performance, among many other advantages to be gained. 
   On diagram sheet 4/9,  FIG. 19 , there is displayed a more detailed derivative technology model, where just the double crankshaft and the connecting rods (articulating) are done away with and therefore a safety ring is added (this is a soft material such as rubber, nylon, ambatex, or any other similar material), shown as number  127 , the purpose is to reduce any collision impact between the two pistons. Two equal polarity magnetic extremities may be placed at both ends (repellant, known as “permanent magnet” or “electro magnets”) on the piston tips (this is also for reducing the impact). Or there may be a spring placed between the two pistons (for avoiding collision impact and favor harmonic oscillatory movement. Numbers  128  and  129  display electromagnetic coils (there may also be only one coil, for each piston, the designer may choose this option), which are activated from the magnetic core  130 , piston  131 , moving linearly (back and forth). Numbers  132  and  133  display the fluid compressor chambers. Numbers  134  and  135  are non-magnetic rings (and preferably, they are electrical non-conductors), for spacing between the coils. 
   Another detail on diagram sheet 4/9,  FIG. 19 , number  136  displays a ring fitting for attaching coils  128  and  129 . Number  137  displays a protuberance on the cylinder wall. The main purposes are: mechanical support for the coils; and reinforcing the cylinder wall against internal mechanical pressure produced by the pressurized fluid. 
   Number  138  shows the hole for the fluid entrance and exit. 
   Number  139  shows a compartment for housing an electronic component set for controlling the coils, as well as, controlling the position sensors (that show the position of each piston), while the equipment is operating (going back and forth) these may be an inductive sensor, capacitive sensor, or others, etc. 
   This model runs the same as those that are based on the double crankshaft and connecting rods. 
   Although, there is a need for a dependable electronic controller (this needs to be well-adjusted), and that slides almost frictionless, keeping the oscillating movement, perfectly symmetric, and unsynchronized (out of phase) to eliminate all vibration. 
   On page 6/9,  FIG. 24 , an optional construction design is displayed, without any “articulating connection rod.” However, there are two “different diameters of pistons.” Number  190  displays the external cylinder (which is also the external housing). Number  191  displays the two-halves of the values fitting (as if there were “two shells” that close uniformly). Look at the left piston: number  192  displays the larger diameter and number  193  the smaller piston. Number  194  displays the central compressor chamber. 
   It is possible for computer cooling use, such as “REFRIGERATED MICRO-PROCESSOR” (especially in the model presented on Page  4 / 9 ). It is not necessary to “refrigerate,” but just “does not let it overheat” beyond a certain limit, this if for “doing away with condensed water,” keeping it dry and safe. In the same way, using our technology there are many novel uses, or improvements can be performed on various technological fields; including lightweight, low volume, low energy consumption, also it does not harm the environment and includes a low cost, etc . 
   Applying our invention (double piston, double crankshaft, articulating connecting rods, etc . ) and it is operates on a solenoid coil, therefore eliminating any unwanted vibration (or it can unnoticed, this is; for example shown on diagram  4 / 9 ,  FIG. 15  and  FIG. 18 . However, an electric motor may be used, with “little vibration,” reduced but still there is unwanted vibration, on account of the intermittent motor torque. Still, “the old-fashioned vibration” caused by the intermittent vibration of the piston (present in the present-day technology) is done away with (out of phase). 
   On page 6/9, an optional construction design is displayed, without any “articulating connection rod.” 
   However, there are two “different diameters of pistons.” Number  190  displays the external piston (which is also the external housing). Number  191  displays the two-halves fitting (as if there were “two shells” that close uniformly). Look at the left piston:  192  displays the larger diameter and  193  the smaller. Numbers  194  and  195  (being that  195  is symmetric to the compression chamber from the opposite side) display compression chambers (or combustion if applied in this specific unit, the object for our present patent, for combustion engines). Number  196  displays the “single connecting rod” (that is “non-articulating,” which is also symmetric),  197  displays the cavity for housing the “single connecting rod” and  198  displays a pin (axle, ball bearing, or screw) that attaches the connecting rod in its proper placement. 
   View  25  displays an external view from the outside of the closed unit (after assembling). 
   Still referring to page 6/9,  FIG. 26 , displays a cutaway view of cylinder  190  (see  FIG. 24 ), whereas  199  and  200  display the larger and smaller diameters, respectively. Number  201  displays the outer walls (similar to two shells that close together forming a “sealed covering,” or housing). 
     FIG. 27  displays the construction method for the unidirectional valves. 
     FIG. 28  displays a lateral view for the two-diameter piston, separated (this separation of the unit is for improved visualization).  FIG. 29  shows the same piston, now from the front view. Whereas  199  is the larger diameter and  193  is the smaller diameter.  197  is the connecting rod fitting. 
   On page 7/9, another optional construction method is shown whereas there is just one external cylinder (see  210 ,  FIG. 30 ) and only one internal piston (see  20  on the same  FIG. 30 ) thereby profiting from some of our technology properties; the object of our present patent, that relates to: the fluid compression at both extremities of the piston. 
   Even yet on sheet 7/9,  FIG. 30 , there is a perspective view of the unit, the motor has been removed from the drawing for improved visibility of the unit (since the motor is not the main aspect of our present patent), although, the motor axle is fitted in at hole  212  on the drawing. 
   The axle rotation  212 , consequentially transmits rotational movement to rod; this rod is fitted by the pin or rotational axle  214 , to the other rod shown by  215 , like this, this rod  215  functions as a connecting rod, whereas it is held in place by the pin or rotational axle  216 , to the piston  211 , making this last movement in a back and forth direction inside the cylinder  210 . Numbers  217  and  220 , displayed in the symmetric slot on the piston, leaving a physical space for fitting in the mechanisms (this is: rod, connecting rod, pins, etc . ). Number  221  shows the symmetric slot on the opposite side, in this manner  222  shows an empty space (that can optionally hold lubrication oil), similar to the space shown by  223 . Number  224  displays a flange (or a hole in the housing), for fitting in the motor. Numbers  225  and  226  display the compression chambers. 
   Another detail on sheet 7/9,  FIG. 31 , displays “TOP VIEW” for the unit. 
   Cutaway  32  displays a cutaway view of the unit (see cutaway line displayed on the diagram  FIG. 31 . Number  50  is a flange for fitting in the motor. Number  227  displays the space (intersection) between the external cylinder  228  and the piston. This piston can be built from various materials such as: Teflon, nylon, aluminum, steel, etc . 
   On diagram sheet 8/9  FIGS. 33 and 34  is displayed a derivative model of this invention, the object of this present patent, this particular use is for the automotive field (air-conditioning), to be more specific: Applied to the external axle, for example the combustion engine, etc . utilizing a drive belt, gears, gear housing, etc . 
   Another detail on page 8/9,  FIG. 33 , this displays the compressor equipment set (the same as the above mentioned),  230  is the double crankshaft axle, which now, in this specific model, goes through the gear housing (it is possible to use, the oil retaining seal, or rubber gasket) and through the conical gear transmission (see  231  and  232 ), rotational movement is dislocated to axle  233 , that by the oil retaining gaskets  234 , going through housing  236  dislocating rotation to the pulley, in this case the movement is the direction of the transmission rotation, this goes the opposite direction of pulley  237  to axle  230 , so that the rotational transmission propels compressor equipment set  238 . 
   The housing (gear housing)  239  is optionally bathed in lubricating oil, then there may be a gasket on the roller bearings where the axles come out  230  and  233 . 
   Numbers  240  and  241  display the support base, or the attachments for the automobile, truck, or any other vehicle or stationary motor housing. 
   Another detail on sheet 8/9, is  FIG. 34  that shows a more appropriate model for automobiles, where the compressor equipment set has two orthogonal compressor cylinders (which is an external housing casing, a cross shape, or in other words: perpendicular to each other), forming as such a double fluid compressor chamber, making it possible for faster drainage, increasing the refrigeration capacity. Number  242  shows the “orthogonal equipment set,”  243  shows one of the compressor chambers,  244  is the piston (there is a total of four pistons, but it is possible to build up to eight or more pistons. Like this, doubling the compression chambers). Numbers  245 ,  246 ,  247 , and  248  are the piston ends at a 45 degree angle, forming in such a way a “five compression chamber” every time the four pistons meet at this position, the quadruple chamber is shown as  249 . Number  250  displays a hole (or canal) for the fluid inflow and outflow, naturally going through the unidirectional valves (that has already been explained in this report). 
   In automotive vehicles (air-conditioning), our technology can be applied extremely well, including many innovative applications. For example, there is less energy consumption; it cools much faster; and etc . ). This is the object of our present patent, without a propelled axle, then it is propelled by electricity, straight from the solenoid coils, promoting as such, intermittent advance and retraction of the pistons. 
   On diagram page 9/9, there is displayed a cutaway view of the compressor (according to the previous reference (see report, sheet 1/10, line x). There are great features included in this simplified model that are: 
   a) There is no motor for traction (but just a solenoid coil); and 
   b) There are “dual” (tandem) compressor chambers, one on each extremity of the piston. 
   Page  9 / 9  on  FIG. 35 , #  251  displays a hollow cylinder that houses piston #  252 , #  259  displays a ferromagnetic core, the coils  253  and  254 , driven in an intermittent manner driving the piston (back and forth). 
   The piston is in the retracted position (according to the diagram shown  FIG. 35  sheet 9/9), the compression chamber “A” is full of fluid, causing the coils to move compressing the fluid and expelling it through hole #  255 . Now that the piston has been driven forward in which case compression chamber “B”, is driven again by the coils driving the piston that compresses the fluid and expels it through hole  256 . Number  262  displays the piston surface lining that does not suffer any wear (for example: Teflon, or any similar). No.  257  is an optional spring (for piston retraction, in case one wishes to only use “one” solenoid coil (for forward movement). Numbers  253 ,  254  and  258  are the fluid inlets, numbers  263 ,  264 ,  265  and  266  are unidirectional valves, number  268  is a pressurized fluid “deposit” (to improve continued drainage). 
   Numbers  269 ,  270  and  271  symbolically display a closed circuit (similar to that which takes place in a refrigerator, with a vaporizer, condenser, etc . ). 
   Other details on sheet 9/9 are  FIG. 36  and  FIG. 37  that display a simplified design of the electrical signal that drives the pumps (to cause intermittent driving of the solenoid coils, thereafter causing the back and forth piston movement). 
     FIG. 23  displays a simplified explanation on how the two compression chambers are formed while only using a “single” external cylinder and just one piston.
