The present invention relates to a device for improving energy generators with multiple functions driven by the combined application of heat sources of different temperatures acting on a sealed and motive condensing capacity.

It is intended mainly for the application for domestic and industrial purposes of combined thermal and mechanical energies, generated from motor-compressor devices with integrated thermal cycle contained in a sealed manner

10 in closed and modular enclosures.

Known devices with thermodynamic cycle generate mechanical energy recoverable on a motor axis, but do not exploit the heat contained in the thermal circuit after the expansion of the volatile motor fluid, which must be removed • _j r through suitable condensers for this purpose, not having multi-compressor and mechanical assemblies.

In addition, they mainly consist of a driving fluid loop acting on a motor connected to a condenser by pressure lines and external pipes which develop random physical phenomena linked to their realization, affecting the general efficiency.

The object of the present invention is to at least partially remedy the drawbacks mentioned above and to provide a multifunctional device of modular type which exploits and combines for all purposes the said thermal and mechanical energies generated from a motor group. thermal compressor and its constituent elements integrally contained in a closed enclosure and tightly connected to at least one fluidic multi-stage heat transfer loop forming a heat pump with successive stages partially contained in said closed enclosure forming a sealed capacity assembly and modular condensing motor for all purposes, containing at least one motor-compressor group forming at least: ^*

(A) a compression assembly with at least three offset compressors 35 of which (a) the inlet is connected to at least one multi-stage steam source, one of the elements being at least partially contained in the engine thermal circuit and of which (b ) the exhaust is connected to at least one multi-stage condensation capacity, forming in combination with the evaporation capacity, a heat transfer device with reverse cycle heat pump (B) an engine assembly with at least three engine pistons for driving said compression assembly.

According to other characteristics, the engine assembly and the compression assembly each comprise three cylinders with sliding pistons, the engine pistons mounted in parallel forming a reference plane, being arranged orthogonally to the compression plane actuated by au _. minus a judiciously profiled cam, mounted on an axis forming a crankshaft animated by the engine pistons acting in combination and in conjunction with a flywheel constituting a means of circulation of the working fluid in the sealed enclosure, - of acceleration 1'échappement of this Luide through a conduit provided for this purpose ^• connected to the axis of rotation of said flywheel:

The engine block assembly with at least three cylinders

15 in which the expansion of the working fluid takes place, is tightly connected by inlet and outlet ducts res- to a source of steam forming a pressure boiler and to the duct d. ' acceleration of the exhaust connected to the flywheel and penetrating, at least partially into a

20 reinjection circuit containing the condensed fluid returned to the "said boiler under the action of a three-cylinder assembly and. Animated __>" "- reιnjectιonγpar pistons. At least one eccentric mounted on the axis of said crankshaft

The plane of the said three reinjection cylinders is parallel to the plane of the said three compressor cylinders and orthogonal to the axis of the said crankshaft and to the plane containing the said three engine pistons,

A distribution device with rotary elements is provided and it consists of an intake slide designed to supply 0 successively the three following engine pistons. a very precise chronology, and an exhaust drawer designed to allow the evacuation of the expanded fluid in the said engine cylinders, also following a well specified chronology.

The said drawers are set in motion by the crankshaft; ^ό According to an advantageous embodiment, these drawers are driven by a chain connected to one axis of said crankshaft which acts on one of the drawers, which drives another drawer, such an embodiment allowing access to the "setting" of the distribution. According to an advantageous embodiment, the said intake and exhaust drawers are in intimate contact at the intake and exhaust ports, with capsules of suitable shape, perforated in their center to allow free passage of the working fluid, which exerts on the walls of said opposite capsules the walls into intimate contact with the so-called ^'drawer, a thrust which is added to an elastic means ensuring the permanence of said intimate contacting.

All of the above components are contained in a waterproof card _. forming -motor capacity -.e. -of -condensate in -which circulates the working fluid. - ^• -

The engine pistons on which the pressure of the condensing working fluid is exerted in a so-called sealed condensing capacity produce a constant pressure • opposing the expansion of the working fluid in the driving cylinders. According to other characteristics, the thermal motor-compressor device forming the motor and waterproof condensing capacity described according to the invention, comprises, on request, various partially deformable waterproof capacities for recovering the various vapor leaks and their reinjection on demand. through various sealed conduits, by reinjection pistons positioned in a plane orthogonal to the axis of the crankshaft and driven by a cam integral with said crankshaft axis.

It will be noted that the deformable part of each vapor leakage recovery capacity forms a sealed enclosure and of condensation of these vapor leaks and of balancing of the pressures between the pressure contained in said enclosure which is that of the vapors at least partially. condensed and the pressure of the external medium in intimate contact with said enclosure.

In the same sense, we note:

- that said sealed vapor leakage recovery capacities are preferably carried out to recover the steam leaks at the level of the compressor pistons and the passage through the crankcase of the motor capacity and leaktight condensing by the crankshaft,

_. That they are according to an advantageous embodiment and in leaktight manner integral with the body of the cylinders of said compressive pistons, as well as with said casing and made up of at least two side walls traversed orthogonally according to the application _; either by the axis of a compressor piston or others, or by the crankshaft and as tightly as possible being understood of course as will understand very well the man of the race that, concerning the second application and according to a advantageous embodiment, the side walls of said capacity for recovering steam leaks from inside the motor capacity and leaktight condensation, consist of rotating sealing rings of the type that one usually found commercially mounted without play on said crankshaft and spaced apart by a suitable distance allowing rotation under the best conditions of said crankshaft .. The pressure of the working fluid expanded in the expansion chambers being very slightly higher than the pressure of the condensed fluid, thrust springs or other equivalent elastic devices are generally necessary to ensure evacuation ¬ tion of the working fluid. However, the device according to the present inven¬ tion by the judicious combination of three cylinders and pisotns engines makes it unnecessary to use such devices as it ensures the evacuation of the working fluid by the ef and rotation of the flywheel which is combined with them.

Furthermore, in the known devices, the distribution of the working fluid in said expansion chambers requires compression springs with elements or recall and other elements of ^binding to the mechanical servo piston, which reduces the performance of a not negligible.

_*

The device according to the invention overcomes this drawback thanks to the arrangement and judicious use of the respective position of the engine pistons, cylinders and drawers combined with the advantageous exploitation of the pressure of the condensed fluid contained in waterproof capacity.

It should also be noted that due to the very compression of a gas, the torque of the motors of existing devices is not constant.

Now it turns out that the device according to the present invention also eliminates this drawback thanks to the rational use of a cam acting simultaneously on the three compressing pistons, the profile of this cam being defined and chosen as a function of the fluid to be compressed. , the expansion of the fluid existing in the expansion chambers so that the speed of displacement of said compressor pistons being inversely proportional to the pressure exerted by the compressed fluid on these pistons, allows

10 optimization of start-up and overall performance.

It can then be envisaged that several cams can be associated and arranged in such a way that each can act simultaneously on three pistons in the cases of -operations- _© „of applications justifying several stages of compression. * 5 will be cited, for example, the case of freezing or demineralization of sea water by freezing.

It has already been proposed (in French Patent No. 2,462,584) to also use a cam allowing the displacement of only one compressor piston by displacement of this cam, which is equivalent to saying that at a rate of compression of a given fluid corresponds to only one piston, which excludes good industrial exploitation.

However, the device according to the invention overcomes this drawback by causing one simultaneous drive of three pistons by a

9 ς

"^:> judiciously profiled cam, each piston being in contact with a well-defined portion of the profile of this cam thus constituting a balanced assembly.

It also happens that the motor-compressor described in the French patent mentioned above includes a reinjection pump

30 also actuated by the cam in question, which limits the efficiency, all the more so since this reinjection takes place at the end of the cam's travel, when the compression ratio tends towards its maximum.

However, the device according to the invention also obviates this inconvenience.

35 comes because it allows the reinjection of the condensed fluid during the start of compression phase when the compression rate is minimum and the speed of movement of the piston .coaprESseur is maximum. In addition, the device according to the invention is designed so that the three intended reinjection pistons are entered simultaneously by the action of a judiciously profiled cam mounted on the axis of the crankshaft which was discussed above.

It will also be noted that in known devices the fluid of the engine cycle condenses in the condenser which removes the calories; a reinjection pump then returns it directly to the high-temperature starting boiler where it. rises in temperature for a new cycle.

However, the rise in temperature of the reinjected fluid requires a calorific contribution "Q" supplied by the hot source. The device according to the present invention is designed in such a way that the condensed fluid is sucked in and then discharged by the reinjection pistons to the starting boiler after possibly having ^; beforehand, recovered at least partially, the heat produced at the compressor cylinders by the compression of the heat pump cycle fluid then, necessarily at least partially that evacuated at the exhaust from the chambers of expansion of the engine pistons.

The quantity "Q" is thus significantly reduced, which further improves the overall yield and reduces the cost of the hot source, in particular in the case where it is constituted by solar panels.

It will be noted that in accordance with the known devices forming a heat pump and according to an advantageous embodiment of said sealed multi-stage heat transfer capacity "" which has just been described, the multi-stage compression unit transferred on demand, the heat of the fluid from the interior of the sealed and motive capacitance of condensation towards the external environment or vice versa, by inversion of the thermal cycle ₍ from the external environment towards the interior of said capacity or any other combination of cycles.

In addition, the cam-compressor assembly forming a compression assembly is exchangeable, which makes it possible inter alia to meet all needs, to use any type of product to be compressed, as well as to ensure in combination with a equivalent compression assembly mounted externally on the axis or any other receiver performing multiple and combined functions " It will be recalled that the motor and waterproof condensing capacity contains at least one evaporator forming an element of the multi-stage waterproof thermal transfer capacity associated in leaktight manner at least partially with a compression assembly according to the invention which evacuates at least partially the heat of the expanded working fluid, by successive compression and successive temperature rises through the multi-stage heat transfer capacity designed and profiled on demand and according to needs; other characteristics and advantages of the invention will emerge more clearly from the description which follows with regard to the appended drawings given by way of nonlimiting examples in which the:

- Figure 1: shows a front view in partial section of the entire device forming a closed enclosure and sealed and motive condensing capacity with multistage fluid transfer heat loop, and. a compression assembly mounted by way of nonlimiting example on the rotating force shaft. -

- Figure 3: shows on a different scale a top view in partial section of Figure 2. - Figure 4: shows a partial side section on another scale showing more particularly the compression assembly and the relative position of the pistons compressors and reinjection with respect to the engine pistons.

Referring to these drawings, the device according to the inventio comprises a closed enclosure of modular type 1 forming a sealed and driving capacity with condensing volume 2, connected in leaktight manner by conduits to at least one multi-stage thermal transfer fluid loop - 3 forman _ reversible cycle heat pump with successive ^* stages ~, partially contained by at least one of its constituent elements in at least one of the capacities forming said closed enclosure 1, and forming at least partial separation with the volume of condensation 2, whose thermal effects of the external environment acting on it by means of the volatile working fluid which it contains, a thrust of opposition forming back pressure on the constituent elements of the thermal motor-compressor group contained in a sealed manner in at least one capacity of the enclosure comprising in: combination :

- An assembly forming a cylinder block 4 with at least three engine pistons 4A, 4B, 4C for driving an assembly forming a compression cylinder block 5 with at least three compression pistons 5A, 5B, 5C, the axes of which are judiciously located in a plane orthogonal to that containing the axes of the engine pistons, mounted in parallel and forming a reference plane.

This pipe 8A constitutes a heat recovery device in the sense that it absorbs and optionally stores in the material or fluid 8B the heat evacuated at the cylinder exhaust through 8A and returns it to the condensed working fluid circulating against the current in the conduits 8E which pass through 8B before reinjection into the starting boiler, and after aspira¬ tion by the reinjection pistons 6, which raises the temperature of said condensed fluid with a tendency to reach temperature and. therefore the pressure of the working fluid contained in the starting boiler.

-A rotational drive device 9 of a shaft 11, possibly with an additional device 6 for reinjecting steam leaks with pistons 6D, 6E, 6F.

- 8U at least one device forming recovery of said leaks by balancing pressures 15 - 16 - 17 - 18 - 19. A device for setting in motion, conduits, 7A, 8, constitutes of a part chain 9A connected from one to a roller 9B for regulating the speed of rotation of said conduits, secured to the shaft 11, on the other hand to at least one of said conduits, which drives the other by the kinematics This shaft 11 actuated by the engine pistons comprises:

on the one hand, on the one hand, a cam 12 profiled as a function of the desired compression ratios and acting simultaneously on the three piston-compressors each located at a precise phase of compression, therefore at a determined position in their cylinder d on the other hand, an eccentric 12A, acting simultaneously on the leakage reinjection pistons, each being positioned precisely with respect to the engine pistons and the compression pistons, and according to the type of leak to be reinjected

- On the other hand, on the one hand an eccentric 12B acting simultaneously on the three pistons for re-injecting the condensed motor fluid, each being positioned precisely with respect to the engine pistons and the compression pistons, and in its cylinder in such a way and according to an advantageous embodiment, that the reinjection of said condensed working fluid into the starting boiler is carried out by successive phases, on the other hand, a flywheel with fins 1, intended mainly for the transfer of gas from the sample to the capacity of. condensation, through conduit 8A, 8D

The axes of displacement of the reinjection pistons and of the compression pistons being in parallel planes are arranged with a judicious offset .uns with respect to each other so that for each cycle, the reinjection takes place in the phases of least compression work and maximum displacement speed of the pistons. If the type of compression to be achieved, for example high compression rates, is provided at least one cam per compression assembly.

On request, at least one end 11A of the shaft vilebre¬ quin 11, passes in leaktight manner at least one wall 1A of the closed enclosure 1. To achieve this objective, and according to a preferred embodiment, the shaft 11 comprises at least two sealing rings of the rotating type 15, 16, forming watertight side walls with a capacity for recovering leaks 17, they are mounted without play on the shaft 11 and in the wall 1A - or any other positive device tightly connected to said wall 1A - allowing the free rotation of said shaft 11.

Said rings 15, 16, are positioned in planes orthogonal to the axis of the shaft 11, and separated by a suitable distance, in order to receive leaktight the leaks in question.

The capacity 17 is connected by at least one sealed conduit 18, to a capacity 19 deformable by pressure balancing. The fluid leaks having passed through the ring 15 forming an oaroi. sealing condense and are reinjected on demand by the piston 6D (for example) through the conduits 29 and 30 in the engine thermal cir¬ cuit. The deformable capacity .19 located exté¬ laughing at the closed enclosure 1,2 forming a device for balancing the pressures with the external environment preventing any further leakage of fluid through the sealing ring 16 forming a tight side wall.

It will be noted that, depending on the applications and the degree of sealing sought, several rings forming successive sealing walls will be mounted in combination forming successive leakage recovery capacities 17, 17A, 17B ,,. (Not shown on the drawings), each of them then being and according to an advantageous embodiment connected in an etan¬ way to a deformable capacity for balancing pressures 19, 19A, 19B ..., by sealed conduits 18, 18A, 18B. .., each contained in a surrounding medium exerting on each of them its own opposition pressure.

According to an advantageous embodiment, the thermal transfer fluid loops contain a volatile refrigerant fluid in circulation under the action of the compression pistons 5A, 5B, 5C, each being at a precise compression phase don¬ born by the profile of the cam 12, forming a multi-stage heat transfer heat pump between the evaporator 20 and the condenser contained in the thermal evacuation stage 3C, successively through the fluid loops C1 _. C2, C3, each of the pistons 5A, 5B, 5C providing work equivalent to the lowest possible compression ratio in order to optimize the coefficient of performance, respectively connected to the corresponding fluidic loops, preferably made up of at least minus an evaporator, a condenser, a holder (possibly a oil separator) and sealed conduits for connecting these constituent elements to each other partially contained in the capacities

2i 3A, 3B, 3C.with material, or thermal accumulation fluid. It will be noted that the closed enclosure 1. contains the evaporator 20, a constituent element of the multi-stage heat transfer capacity 3 _> which can function as a condenser by reversal of the thermal cycle using a four-way valve (not shown in the drawings), as in the case of known heat pump devices, it being specified that this evaporator

20 is placed in a sealed envelope 21, comprising a material or other product 22, intended to absorb the calories of the fluid which passes through it through conduits 21A, and possibly another means of communication Eό, forming inertia and storage capacity, as well as a heat removal regulator linked to the temperature of evaporation of the fluid circulating in said evaporator 20, or of liquefaction in the. condenser 20A con¬ held in the capacity 3A with identical material or fluid 22A. The capacities 3A, 3B, 3C with material 22A, integrating on demand and depending on the applications, the physical phenomena linked to said er.oaporation or condensation temperatures of liquefaction of the fluids circulating in the respective fluid loops. Without departing from the scope of the invention, it will also be noted that, as shown in FIG. 2 and according to another advantageous industrial embodiment, the sealed enclosure 1.2 is made up of various capacities forming sealed volumes, GHJ'K, containing ^' au at least partially an element constituting the thermal oto-compressor group, said volumes being separated on demand by the watertight partitions El, E3, each comprising at least one device for recovering and reinjecting leaks E2, E4 of the type described above ( 15,16,17, 18, 19) crossed on demand by one of said constituent elements such as the mote axis H •

Said capacities of type E2, E4 being positioned on demand anywhere in the device according to the invention in order to isolate as required, in particular lubrication, any functional element or constitutive assembly forming the motor-compress group The combination of these various constituent assemblies judiciously contained in the said sealed volumes juxtaposed with each other in an adapted manner, being a characteristic of one modular aspect of said closed enclosure 1.

5 Thus, under the effect of the flywheel with fins 14, the volatile fluid passes through (arrows Fl) in forced circulation, the evaporator 20 referred to above, contained in the caisso 21 containing the material where storage fluid 22 to which it releases its calories and returns to the flywheel (arrows F.2) by the

10 pipes 23 provided for this purpose. -forming turbulence.

It will also be noted that the evacuation of gas from the engine cylinders at a pressure very close to that of the condensing capacity 2 virtually eliminates the need for gas expansion in said condensing capacity 2 forming _j volume J, which promotes good performance and this thanks to the action of said flywheel 14 with fins which directly discharges the engine exhaust fluid in said sealed volume oto-compressor J, without this fluid being channeled by a duct outside the closed enclosure 1.2. - This version of the heat transfer capacity 3 given by way of nonlimiting example can however be adapted for other specific applications, which may justify the use of several different heat transfer fluids, for example a refrigerant loop operating in heat evacuator

2c fique the other two operating in cold production.

For this purpose, sealing must also be ensured between the various fluidic loops and the engine thermal circuit. According to a preferred embodiment, each compressor piston will include a leakage recovery device directly _Q inspired by the leakage recovery device 15 ₅ 16, 17, 18,

19 described above, possibly with a capacity containing a lubricating oil which will be recovered by an oil separator and reinjected by a reinjection piston 6.

It will be noted that, just as for the reinjection pistons, the 5 compressor pistons are provided with various elastic means per¬ putting permanent contact with the different cams, judiciously combined with the functional exploitation of the pressures of the fluids contained in the thermal circuits. and fluid loops and acting on said compressor pistons in order to; . , - provide in combination with the profiled cams an operation of the constant torque device.

It will also be noted that, with the aim of minimizing leakage and friction between the pistons and their cylinder, respectively, said pistons comprise, according to an advantageous embodiment, a sealed and deformable capsule 24 under the effect of a volatile fluid contained in tightly in said capsule 24, the pressure of which varies as a function of the thermal environment surrounding said piston so that it exerts a thrust on the walls of said capsule acting by deformation on the segments 25 as¬ ensuring self-regulation friction and wear compensation, the conduits 7A and 8 being provided with 25 A capsules whose contact surface is adapted to avoid excessive friction and mounted in the upper parts of the engine cylinders as shown in the figures 1-2- 3-4 _;

It will be concluded in synthesis from the description which has just been made of the invention that all the physical and thermal phenomena linked to the behavior of the working fluid in circulation in the thermal circuit in its phase of condensation then of re-injection as well as the various paths traveled take place inside a closed modular enclosure 1,2 forming a capacity integrating all the various constituent elements com¬ taking at least one motor-compressor group with at least three engine cylinders 4A, 4B, 4C with distribution device 7A and exhaust 8 for forced circulation of the working fluid by flywheel 14, and heat absorption duct SA tcav a material or other suitable product, 8S., for the purpose of resti¬ tution of heat absorbed, to the condensed working fluid returned to the boiler 27, a compression assembly with at least three pistons 5A, 5B, 5C positioned in a plane orthogonal to that of the engine pistons s, and other leakage recovery devices 15, 16, 17, 18, 19, it being specified that the compression pistons are tightly connected to the elements of a multi-stage thermal transfer fluid loop 3 forming a pump heat at least partially contained by an element 20 forming an evaporator in the closed enclosure 1,2, the reinjection pistons 6A, 6B, 6C, being connected on demand and sealingly by conduit 28 to the boiler 27 of the working fluid, connected by sealed conduit 2δA-to the distributor device 7A, while the ,, requests the various thermal circuits sucking in sealed conduits 29, possibly 30,31, then compressing through the sealed conduits 32,33,34 the various leaks of fluid and r others.

The combination of several devices according to one invention providing an on-demand all the _ζ optimal exploitation of thermal energy by cascading effect, each device operated by operating at least partially heat the fluid contained in the device who is before.

Other details on the different characteristics of the

20 device according to the invention which has just been described will appear in the description given below of some examples chosen from the multiple applications of the device among which there will be mentioned in particular: a) the achievement of a sealed and driving capacity

25 densatioπ forming a multi-functional digester with integrated thermody¬ namic cycle, generator simultaneously a) of thermal energy distributed through the multi-stage capacity 3, the judicious distribution of the constituent elements of which will allow optimal use of the different fermentation phases and

30 digestion of waste of all types -i ^' omasse, household waste,) livestock waste, green plant material etc), optimizing the production of bio-gas by a permanent calorific intake at the desired temperature being specified that the biomass and other waste is contained in a digestion tank and at least partially

It will be noted that this type of digester with thermodynamic cycle integrates. with multiple functions can equip a vehicle and function by exploiting the heat of the vehicle engine which, by its usual cooling circuit, will thermally supply the 2όAj accumulation material. In the vehicle stop position, a battery of absorbers of the solar energy, fused and structured in harmony with the said vehicle, will combine the recovered solar heat with that contained in the storage capacity 26. Given the calorific power available to the vehicle engine, several devices according to the in¬ vention can be combined for multiple purposes; grain escapes in fitted silots, in combination with the digester, ^ and other biomass applications, production of hydrocarbons by the combination of a high calorific intake (250 ° c) and a high compression of the so-called biomass (200 kg / cm2) and others. b) The realization of a multipurpose cold room mainly by the at least partial recovery of the motive heat circulating in the sealed and motive condensing capacity 1 and through the multi-stage capacity 3, and so elevation to a usable temperature for domestic purposes (heating the water of a cumulus, for example to 100 ° C.) under the action of the compression assembly stage 5, contained in said capacity 1, combined with the production of cold by a compression assembly 35 mounted on the axis 11A and connected to various refrigerating loops, it being specified that the sealed condensing capacity 2 will be at least partially profiled so as to integrate at least partially to said cold chamber in the double wall of which a fluid possibly circulates and that the thermal accumulator 26 will be supplied in combination with other heat sources, by an electric heating resistor 39 making it possible to use at best off-peak times in the urban power grid.
