Abstract
The present invention relates to a system for constructing rotary compressors and motors, each comprising two rotors with one, two or more plungers for each rotor, in order to create two or more chambers between the plungers. The chamber volume varies depending on the distance between the pistons, which results from the variable and alternatively opposite speeds of two of the rotors. This variation in speed can be obtained by various types of systems characterised in that the length of the radius of transmission or reception of a regular and uniform rotary movement is varied, transforming said movement into an oscillating movement having a variable speed or vice versa. The new system is characterised in that two mechanisms are used together or separately. One of the mechanisms dynamically modifies the distance between the plungers, in that the actuation mechanism or motor is arranged on sliding rails and is moved by means of a shaft, hydraulic piston or gear system, and the other mechanism dynamically modifies the beginning of the intake and compression phases, preventing the stoppage of the plunger in certain segments of the intake-compression chamber, excluding a chamber segment by a similar actuation mechanism, creating a fixed or variable opening that allows the passage of fluids and prevents the displacement thereof. The combined action of these two mechanisms is monitored by a sensor-fed computer system, allowing the parameters of the motor or compressor to be dynamically changed in order to achieve an improved and more efficient energy utilisation.
Description
SYSTEM FOR THE CONSTRUCTION OF ROTARY COMPRESSORS AND ENGINES, WITH VOLUMETRIC DISPLACEMENT AND RATE OF
DYNAMICALLY VARIABLE COMPRESSION
Description of the invention
The present invention relates to a system for the construction of compressors and rotary engines composed of two rotors with one, two or more pistons per rotor, so that two or more chambers can be created between the pistons, depending on the quantities of pistons by rotor. The chambers vary their volume according to the degree of distance between the pistons caused by the varied and alternately opposite speeds between the two rotors.
This variation of speed can be produced by various types of systems that have as characteristic the variation of the length of the radius, in which a regular and uniform rotary movement is transmitted or received, transforming it into an oscillating movement, of varied speed or vice versa.
As an example of this type of mechanism, those compounded by a double crank axle articulated with sliding connecting rods or rotating connecting rods, working in opposite positions articulating with the arms attached to each of the rotors and spaced from the geometrical axis of the rotors, can be enumerated. same.
Ref.:229793 This distancing allows the variation of the length of the radius in which the movement is transmitted, thus transforming a uniform movement of the double crank axle in a varied movement of acceleration and deceleration in the rotors with their pistons or vice versa. As well as systems that use a fixed solar gear around which move planetary gears that support axes spaced from the center of them. These axes are connected to the arms of the rotors through transmission rods of movement. Another mechanism uses elliptical gears connected to the arms of the rotors by means of rotating connecting rods.
The new system is characterized by using two mechanisms jointly or separately. One of them dynamically modifies the distance between the pistons and the other modifies dynamically the beginning of the suction and compression phases. The alteration of the distance of the pistons is achieved through the dynamic modification of the distance between the geometrical axes of the drive mechanism and the motor or compressor, placing at least one of them on sliding rails and moving it by means of a spindle, hydraulic piston or a geared system, will approach or distance the pistons increasing or decreasing the compression rate as proposed by this innovation.
The other mechanism alters the volume displaced in the intake and compression chambers, consequently changing the volumetric relationship with the combustion and extraction chambers. This difference in volumes is achieved by preventing the tightness of the pistons in certain segments of the suction-compression chamber, by means of a distance between them, creating an opening that allows the passage of fluids and prevents the suction and compression of the same for the pistons. In this way it is possible to decrease the volume displaced in a fixed manner, by practicing a definitive depression / cavity in at least one of the walls of the chamber, which extends the entrance of the suction, for example, (Fig. La) or variable to through the displacement of one or several sectors of the chamber that are withdrawn or move away from the action of the pistons by means of any mechanical system, creating an opening between it and the pistons, reducing the sealing areas of the chamber ( fig ib).
This alteration of the displaced volume can be modified, the system being stopped or moving.
The joint work of these two mechanisms allows that the decrease or increase of the volume displaced in the suction phase does not undesirably alter the compression rate of the motor or compressor. For this it is necessary to reduce or increase the compression rate, adapting it to the new admitted volume. Suppose we want to work with a compression ratio of 1 to 9, and practice a cavity in one of the walls of the chamber so that it only extracts and compresses 50% of the total volume, under these conditions the compression rate will decrease to half (1 to 4.5). It will be necessary to decrease the distance between the pistons to reach again a compression ratio of 1-9. We will thus have a decrease in the extracted volume,
but we will maintain the desired compression rate, while at the same time we will have twice the volume in the combustion and discharge chambers. Under these conditions, if one or several segments responsible for the reduction of the suction-compression chamber were repositioned allowing greater angles of action of the pistons, the compression rate should be altered again, which will increase proportionally to the increase in volume of fluids displaced.
The movement of these segments of the chamber can be manual, mechanical, or hydraulic through a suitable electric motor, which obeys a computerized program with preestablished responses, fed by readings of temperature sensors, speed, torque, quality of combustion , etc. and other information offered. Thus, the volume displaced in the suction and in the compression can be modified, together with the compression rate of an engine, or of a compressor, for example, during its operation, optimizing its performance.
It will thus be possible, at high speeds, to increase the volumetric efficiency of the system, adapting it to the different speeds.
By reducing the extracted and compressed volume, in the case of a combustion engine, the size ratio is automatically modified with the combustion and extraction chambers, thus allowing the increase of time and volume to carry out the same, guaranteeing a greater use of the expanded gases and a better combustion of the mixtures. This difference, which will result in an increase in yield and decrease through efficient combustion of toxic waste (C02, Hydrocarbons) common to poor combustion.
The energy and environmental crisis caused by low energy efficiency polluting technologies, requires new equipment at the compressor and motor level that reduces the environmental impact, minimizing harmful emissions and maximizing the energy consumed. The use of new renewable fuels such as: biodiesel, alcohol, hydrogen or other less polluting fuels such as natural gas, require combustion engines that can operate efficiently with all of them, that is, with the ideal compression rates for each one. .
On the other hand, current internal combustion engines (alternative and rotary) do not work with the ideal compression rate for each speed-torque situation, on the contrary, they are adjusted in such a way that pre-knocking can be avoided. Turbines have been adapted to provide air at a higher pressure than the atmospheric one and in this way get a good breathing of the engines, increasing the volumetric capacity of the same.
But these turbine engines have limits to increase their volumetric capacity, marked by the increase in the compression rate that can be achieved without damaging the engine itself. Modifying the variable displacement in reciprocating motors in a variable way is a difficult task to be carried out, since the four phases: suction / compression / combustion / extraction, take place in the same cylinder, both in the cycle
Otto, as in the two-stroke or when the four phases are performed in the same cylinder. On the other hand, the reciprocating engines lose around 20% of the combustion gas pressure, since they have to open the discharge valves in advance, generally 60 degrees before the final route, in order to facilitate the extraction of the gases and allow the suction cycle to not be obstructed by them. The combustion of the mixture is also affected by the geometry of the reciprocating engines, which can not dispose of larger combustion cylinders, able to take advantage of the expansion of the combustion and efficiently complete it, so as not to produce high Polluting waste indexes. To mitigate the effects of poor fuel combustion and eliminate part of the hydrocarbons, C02, etc. catalytic filters have been developed, which, in addition to the high cost and short life, do not effectively resolve the emission of polluting gases.
On the other hand, "flexible" motors have been developed that, through electronic advance programming, modify the power and ignition parameters, according to the reading of sensors, adapting them to the different types of fuels. The electronic mechanisms make the combustion engines flexible, but they do not manage to cover very different compression fuels (diesel and gasoline, for example) and do not achieve optimal performance for any of them, since the compression rate remains fixed, preferably suitable for fuel that requires less compression.
The dynamic variation of the volume displaced in the phases of suction and compression, together with the dynamic variation of the compression rate, the use of combustion chambers and extraction of greater volumetric capacity than those of suction-compression, offers an interesting solution. In the case of internal combustion engines, it will allow a greater energy use and a sensible reduction of toxic residues of combustion as well as the use of different fuels in an optimized way, using the specific compression rate for each of them. The variation of the compression rate during the operation of the engine in different rotations per minute, taking into account the information issued by different sensors (operating temperatures, torque, fuel type, richness of the mixture, efficiency of combustion, etc.) It will allow you to make the most of the most different fuels without running the risk of early detonations. The present invention also allows the modification of the position of the intake and discharge windows and spark plug, in relation to the position of the pistons. This is possible when a planetary system is used through the modification of the angular position of the solar gear in relation to the satellites. This new system also allows the incorporation of a much more efficient mode of a turbine in the feed, now not limited its performance by increasing the compression rate that is dynamically variable. Finally, by reducing the suction-compression chamber, we create a space inside it where the air-fuel mixture is preheated and homogenized before being compressed. This guarantees better conditions for a complete and faster combustion, which will result in a greater and cleaner energy efficiency. In the case that this system is used for compressors, it will allow the compression with different rates and volumes of the fluids with which it works. In the case of refrigeration compressors, for example, now controlled by thermostats or by expensive systems of variation of speed, will allow an efficient control of the required temperature, modifying the rate and / or the volume displaced, thus reducing the energy consumption and increasing the useful life of electric motors that are not required, as in the use of thermostats, to continuous stops and starts, which increase energy consumption and reduce the useful life of the equipment.
Several types of compressors and rotary motors have been invented, based on the movement of two rotors with at least one piston each, which travel at varied and alternately opposite speeds. This movement of variation of speed is done through different mechanisms, among which we can basically list:
1) Planetary gear systems;
2) Systems with elliptical gears;
3) Systems with sliding rods;
4) Systems with rotating connecting rods.
All of them presuppose fixed relations of eccentricity, and in the case of using planetary mechanisms, fixed relations concentric to the geometrical axes of the motors. Several rotary motors with the mechanism of variation of the relative speeds between the two rotors based on the use of planetary gears were idealized. They all work with a fixed solar gear around which rotate at least two satellite gears in opposite positions. The gears support axes spaced from their centers, which are articulated to the arms of the rotors through rotary transmission rods of movement. The ratio of reduction between the solar gear and the satellite gear is determined by the number of pistons that each rotor supports, being 1 to 1 when it supports a piston each, 2 to 1 with two pistons per rotor and so on. The distance and the relative position of the center of the satellite gears of the axes, joined to them, the length of the arms of the rotors and of the transmitting rods of movement, determines the variation of the relative speeds between the rotors and their respective pistons .
The united shafts, spaced apart from the center of the satellite gears, rotate around the solar gear, alternately moving away from each other and moving closer together, changing the length of the radius in which the movement is transmitted, causing a change of speeds and even in certain relations and positions, even cause the arrest of one of the rotors.
The planetary systems were always projected to work in a concentric way to the axes of the engine, attending to a concept of simplicity, robustness and minor final size of the artifact. In this way, the solar gear was firmly attached to the motor armature and concentric to its axis. The present innovation proposes to dynamically distance the planetary mechanism of the motor or compressor, in order to change the compression rate.
In order to be able to separate the geometrical axes using more than one piston per rotor, the present invention proposes to use a geared reduction between the arms and the rotors, proportional to the number of pistons per rotor. This type of reduction must also be applied in cases where double crank shafts are used, articulated with the arms of the rotors by means of sliding elements that move from the crank shaft or by double crank shafts articulated with the arms of the crank. the rotors by means of rotary transmission rods of movement. Both mechanisms require a geared reduction when they work with more than one piston per rotor since they produce a speed oscillation at every 360 degrees which makes them incompatible to operate in cases in which 180 degree cycles are necessary as in the case of rotors that support two pistons each.
Along with the more traditional advantages that rotary engines offer in relation to the alternatives, namely: smaller size, fewer moving parts, less vibration, less weight, lower production cost, the new engine aims at greater energy use and a significant decrease in the quality and quantity of toxic waste derived from combustion.
This is possible for several reasons:
(1) By this innovative system, it is allowed to have a combustion chamber with greater volumetric capacity in relation to the suction-compression and thus be able to take advantage of better combustion the pressure of the fluids in the expansion or combustion phase.
(2) Due to this innovative system, it is possible to vary its displacement, significantly reducing fuel consumption and consequently the pollution emitted, adapting the volume displaced in a programmed manner to the needs of the vehicle, in the case of the engine or the equipment, in the case of a compressor, to work in the best regimes, guaranteeing a better energy efficiency for each speed-torque situation.
(3) By this innovative system, it is allowed to jointly vary the distance between the geometrical axis of the motor and the geometrical axis of the drive mechanism, during the operation it becomes possible to change the compression rate, attending to the needs of torque and speed and, increase or decrease in the volume displaced (displacement) and the type of fuel used: We will have a compression rate closer to the ideal for combustion, attending to each situation and consequently we will obtain a better combustion with less toxic waste, in short, a better use energetic than current engines.
(4) By this innovative system, to be able to vary the angular relationship between the solar gear and those of the satellites, it will be possible a more effective control of the position of the pistons, in relation to the camera and of the suction and extraction windows and spark plug, in relation to the pistons, changing the geometry in different moments of the operation, thus allowing the best performances in relation to the speeds, displaced volume, torque required to the engine, fuel type, etc.
In one of its preferential modalities, the present innovation proposes besides the possibility of using other mechanisms of variation of speed two substantial modifications that create a new mechanism of more versatile drive, allowing altogether or separately, to establish different relations of movement varied among the rotors with their pistons, as well as, control the distance between the pistons.
The first consists of separating the planetary gear system from the engine so that, moving some of them, it is possible to move the distance between the geometrical axes of both and thus control the distance between the pistons attached to the rotors.
By doing this, we created a new mechanism governed by two systems of varied motion. One created by the planetary mechanism and another by the distancing of the geometrical axes of the motor or compressor and of the mechanism of movement united by connecting rods.
The type of combination of these two mechanisms of variation of speed, will make it possible to modify the parameters of movement of the rotors and their respective pistons, according to requirements of the best operation of the engine in different regimes of torque and speed, in the use of different fuels such as gasoline, alcohol, or gas, which has different combustion times, the relative position between the pistons, the time in which we will maintain the same compression rate, the speed of the suction, compression, combustion and extraction phases.
This will make it possible to perfect the mechanism of movement varied in the different phases for a greater energy use and a reduction of the polluting residues of the combustion.
But it will be impossible to join these two mechanisms when we work with two or more pistons per rotor, without modifying the traditional planetary system that needs to use satellite gears of proportional diameter to the solar according to the number of pistons that the rotors support. In the case of two pistons per rotor, the planetary systems were designed to work with satellite gears with half the diameter of the solar. Thus, it produces two different cycles of speed variation for each given round around the fixed solar gear. Yes, we move the geometric axis of this assembly, linked by transmitting rods of movement to the arms of the rotors of the geometric axis of the engine, we would produce another cycle of variation of speed that operates every 360 degrees. Both working together necessarily generate different and inharmonic movements between the rotors. That is why this innovative mechanism, in one of its preferential modalities, proposes a unique planetary gear system, with equal diameter between the planetary gears and the solar gear in order to produce a single 360 degree cycle compatible with that caused by the crank system. When using two pistons per rotor, the new system proposes to intermediate the movement of both, by means of a reduction geared from two to one, placing a gear of half number of teeth on the arm axis of each rotor and a double gear. of teeth in each rotor, which transforms a cycle of 360 degrees of variation into two cycles of 180 degrees.
In the case of using more pistons per rotor, that reduction will be proportional to the number of pistons used, from 3 to 1 for three pistons, from 4 to 1 for four pistons per rotor, and so on.
In one of its preferential modalities the new system places the double crank axle that supports the satellite gears and the shaft of the fixed solar gear on a mancal capable of being moved on rails or a sliding axle by means of a spindle, a hydraulic system, pneumatic or geared, commanded by a computer duly powered by sensor data. And so by changing the distance between the geometrical axis of the motor and the axis of the double crank axis that revolves around the solar gear, it is possible to change the distance between the pistons and thereby change the compression rate.
In one of its preferred modalities, this innovative system for the construction of rotary compressors and motors, offers the possibility of moving the displaced volume, distancing the pistons of certain segments of the chamber in a fixed or variable way in order to prevent in those areas the fluid suction and compression. At least one segment of the chamber, at the beginning of the suction-compression, is moved in a sliding manner by means of a spindle, a hydraulic, pneumatic or geared system, so that this displacement creates or closes an opening between the pistons and the camera, allowing the passage of fluids.
By increasing the extracted volume, for example, if we do not modify the degree of detachment of the pistons, we would automatically increase the compression rate, which would lead to the certain risk of early detonations in certain regimes. That is why of the two mechanisms, the one that allows the moving of the geometry of the chamber to vary the volume displaced, and the one that makes possible the change of the compression rate, are technically impossible to be conceived separately.
By modifying the distance between the geometrical axes, we will modify the compression rate to maintain, for example, the same compression rate of the motor, which can be done while the motor is stopped or in motion.
In one of its preferential modalities these operations can be controlled by a computerized system, which operates together with the variation of the displaced volume, taking into account speed-torque-fuel used, temperature, fuel type, will command the necessary changes for the best and more efficient and clean energy use, as has never been achieved with current engine technology 1
combustion.
The present innovation also proposes in one of its preferential modalities a new mechanism capable of varying the relative position of the pistons in relation to the chamber and its intake and extraction windows and spark plugs. It consists of placing the sun gear on an axis that can be moved and fixed in different positions, so as to change the relative position of the satellite gears and their respective axes attached to the transmission rods. By modifying the position of the sun gear shaft, the relative position of the pistons in relation to the fixed chamber on its suction and extraction windows and the spark plug are also modified.
By joining this axis to any mechanical system, capable of moving the solar gear by means of a suitable motor or by varying the relative position of the camera, it will be possible to make these adjustments during the running of the motor. These adjustments can undoubtedly be commanded by a programmed electronic unit, in order to, in relation to the data sent by the sensors, properly position the solar gear with the intention of perfecting its operation.
The present invention provides one of its preferred embodiments, a system for the construction of compressors and rotary engines with different volumetric displacement between the suction and compression chambers, and the combustion and extraction chambers. The ratio of the volumetric capacities of the suction and compression chambers and the compression and extraction chambers can be fixed or variable.
In another of its preferential modalities, the variation of speed can be produced by various types of mechanisms that have as characteristic the variation of the length of the radius in which a regular and uniform rotational movement is transmitted or received, transforming it into an oscillating movement or vice versa. As an example of this type of system, we can list those composed of a double crank axle with sliding rods or rotating connecting rods working in opposite positions, articulating with the arms attached to each of the rotors and spaced from the geometrical axis thereof. This distancing allows the variation of the length of the radius in which the movement is transmitted, thus transforming a continuous movement of the double crank axle, in a varied movement of acceleration and deceleration, and stops in the rotors with their pistons or vice versa, using any of these mechanisms, characterized in that the compression rate can be altered dynamically, by modifying the distance between the geometrical axes by means of a sliding mechanism, moved by a spindle, a hydraulic, pneumatic piston or a geared system. The movement transmitting rods are articulated directly when the rotors support only one piston each (Fig. 3) and or they will be intermediated by an engaged reduction when working with two or more pistons per rotor (fig.la-2).
In another preferred embodiment, the movement mechanism works with a double crank shaft, which supports two gears with the same number of teeth joined by a chain. axes spaced from the center of the satellite gears are articulated with the arms of the rotors by means of rotary transmission rods. Gear reductions proportional to the number of pistons are used when the rotors support more than one piston each.
In another preferred embodiment of the system of the present invention, it is used for the construction of pumps and compressors of the most different types of fluids, internal combustion engines, thermal, hydraulic or pneumatic.
Figures la - Ib refer to views, of a frontal cut of an engine (left side) and its movement mechanism (right side), drawn separately to facilitate its understanding. The engine has two rotors with a pair of pistons each (2) and (5), which move inside the chamber (1), two windows: a suction (26) and another extraction (25), a cavity in the principle of suction (23), limits the action of the pistons. On its side, a segment of the chamber (24) articulated with the outer ring (1) placed on the fixed outer wall of the chamber operated by a hydraulic piston (22) is closed in the figure and open in figure Ib . The hydraulic device (22) opens a segment of the chamber, creating a cavity preventing the action of the pistons (2-5) reducing by 50% the volume to be displaced and compressed in the suction and compression chamber (34), time, which increases to twice the relative volume of the combustion chamber extraction (35). The combustion chamber where the spark plug (32) is located works with a compression ratio (27) of nine to one in figure la and changes by half bringing the pistons in figure Ib in order to compensate for the decrease in the displaced volume maintaining the same compression rate. This move is operated by dynamically modifying the distance between the geometrical axes (33), between the motor (left side figure) and the movement mechanism (figure right side).
The movement mechanism is a double crank shaft (15) that carries two satellite gears (12-13) that move on a fixed solar gear (14).
Rotating cranks (8-9) transmit the movement of the arms of the internal and external rotors (6-7). These arms are connected to the rotors by means of gears (30-31) with half of the teeth that are installed in the rotors, (28-29) in order to transform a cycle of varied speed of 360 degrees into two cycles of 180 degrees each. In this way, at every 180 degrees of displacement of the double crank axle, the four phases of the cycle are produced
The intake-compression are always operated in the sector (34) of the engine and the combustion-discharge in the sector (35) of the engine. It is noted that in fig. Ib, the chamber (35) has double the volume in relation to the compression intake chamber (34) allowing a greater use of the combustion gases.
Figure Ib shows the enlargement of a sector of the chamber (23) where the air / fuel mixture is heated homogenized before being compressed.
Figures 2a-2b refer to a perspective view of that same engine, shown in the previous figure.
Figure 3 refers to a cut with a top view of a compressor with two rotors: one internal (3) and one external (4) with a piston each (5 and 2) working inside a fixed outer ring (1 ) that slidably supports a sector of the chamber (24) driven by a hydraulic mechanism (22) in order to create a spacing (23) that prevents or not the action of the pistons (2-5) and thus dynamically modifies when the displaced volume is necessary. The rotors (3-4) are joined to arms (6-7) that are articulated by means of rotating connecting rods (8-9) with the satellite gears (12-13) by means of shafts attached to them (10-11) spaced from the centers of the satellite gears that rotate around a fixed solar gear (14).
The satellite gears (12 and 13) are supported by a double crank shaft (15) that rotates about the axis of the sun gear (18) that supports a gear (19) that can be moved by an electric motor (21) with the object of modifying, when necessary, the relative position of the pistons (5-2) in relation to the chamber (1).
The speed variation mechanism assembly is firmly attached to a sliding handle (20) that can be moved on rails (16) by a hydraulic mechanism (17) to modify the distance between the compressor's geometry axes and the axle. double crank with its planetary system and in this way to move the pistons (2 and 5) away or closer by changing the compression rate.
Figures 4a-4c refer to frontal cuts of a compressor with two rotors supporting a piston each (2-5) that move counterclockwise inside a chamber (1) divided into two chambers, one of suction and another Of compression.
Two mechanisms that move by means of hydraulic pistons (22) segments of the chamber (24) that are, one open (23) and another closed. In Figure 4a the suction in the chamber is initiated through the window (26) while the compression in the other chamber begins. In figure 2b an intermediate state is observed and in figure 4 -4c the maximum compression of the chamber between the two pistons meets the extraction window (25) while the piston (5) has not yet started the suction-compression operation .

SUMMARY OF THE INVENTION The present invention relates to a system for the construction of compressors and rotary engines composed of two rotors with one, two or more pistons per rotor, so as to create two or more chambers between the pistons. The chambers vary their volume according to the degree of distance between the pistons caused by the varied and alternately opposite speeds between the two rotors. This variation of speed can be produced by various types of systems that have as characteristic the variation of the length of the radius in which a regular and uniform rotary movement is transmitted or received, transforming it into an oscillating movement of varying speed or vice versa. The new system is characterized by using two mechanisms jointly or separately. One of them dynamically modifies the distance between the pistons by placing the drive mechanism or the motor on sliding rails and moving it by means of a spindle, hydraulic piston or a geared system, and the other modifies dynamically the start of the suction and compression phases preventing the tightness of the pistons in certain segments of the suction-compression chamber, moving a segment of the chamber away by means of an actuator similar to the previous one, creating a fixed or variable opening that allows the passage of fluids and prevents their displacement. The joint work of these two mechanisms, monitored by a computerized system powered by sensors, allows the motor or compressor to dynamically change its parameters for a better and more efficient use of energy.
