Abstract

The invention relates to a modular rotary heat engine. Without pistons, or connecting rods/crank shaft, or valves, very easy to manufacture, including only ten main pieces other than the conventional external accessories, very small, very lightweight, takes any type of liquid or gaseous fuel, and therefore produces very little pollution. Operation is possible in all positions, modular stacking is possible, in order to obtain a continuous engine stroke, by phase-shifting, and considerably to increase the power. This engine is intended to be substituted for all types of conventional heat engines in all power ranges, its mechanical yield is equal to that of hydraulic and electric motors. Its operating and manufacturing principle calls upon only well-known principles, in agreements with the laws of physics.

Description

MOTEUR THERMIQUE ROTATIF MODULAIRE
DESCRIPTION
Moteur sans bielles manivelles,ni pistons,ni soupapes.MODULAR ROTARY HEAT MOTOR
DESCRIPTION
Engine without cranks, pistons or valves.

L'état de la technique à ce jour, n'offre que la machine thermique classique bien connue, à pistons et bielles manivelles,au rendement déplorable, d'environ 20% malgré toutes les améliorations, que peuvent apporter les nouvelles technologies et, bien que déguisées, sous différents aspects de cames et d'excentriques compliquées, n'en restent pas moins un système bielles- manivelles, semblant incontournable. The state of the art to date, only offers the well-known conventional thermal machine, with pistons and crank rods, with deplorable performance, of around 20% despite all the improvements that new technologies can bring, and, well that disguised, under different aspects of complicated cams and eccentrics, nonetheless remain a rod-crank system, seeming inescapable.

Depuis peu, quelques inventeurs, tentent de remédier à cet épineux problème . La solution que je propose, concerne la conception d'un système mécanique, permettant la construction d'un moteur thermique, purement rotatif,éliminant tous les inconvénients précités, et cumulant les avantages. De par sa conception,sa fabrication très simple, et peu onéreuse,ne met en oeuvre que des procédés bien connus et parfaitement maîtrisés, (il ne comporte que 10 pièces principales hormis les accessoires extérieurs classiques).De dimension très réduites,léger,peu polluant, il accepte tous les types de carburants, liquides ou gazeux,peut fonctionner dans toutes les positions, et peut très rapidement s'imposer, et se substituer, à tous les types de moteurs thermiques classiques, dans toutes les gammes de puissances,son rendement de couple, n'a d'égal que celui des moteurs électriques, et hydrauliques (100 % moins les pertes par frottements ici très réduites, environ "7 fois moins"
La caractéristique "modulaire" de ce moteur, lui permet également, l'accouplement par "empilage", l'empilage déphasé assure à l'évidence à l'ensemble, un couple rotatif entretenu absolument constant, ce qui laisse raisonnablement augurer, des vitesses de rotations, et des puissances considérables.Recently, a few inventors have been trying to remedy this thorny problem. The solution I propose relates to the design of a mechanical system, allowing the construction of a purely rotary thermal engine, eliminating all the aforementioned drawbacks, and combining the advantages. By design, very simple and inexpensive to manufacture, it only uses well-known and perfectly mastered processes (it only has 10 main parts apart from conventional exterior accessories). polluting, it accepts all types of fuels, liquid or gaseous, can operate in all positions, and can very quickly impose itself, and replace, all types of conventional heat engines, in all power ranges, its torque efficiency, only matched by electric and hydraulic motors (100% less friction losses here very reduced, around "7 times less"
The "modular" characteristic of this motor also allows it, the coupling by "stacking", the phase shifted stacking obviously provides the whole, a rotary torque maintained absolutely constant, which lets augur reasonably, speeds of rotations, and considerable powers.

Le moteur ce compose essentiellement:
a) D'un bloc parallélépipédique (1), constitué d'un corps solide, percé et alésé de deux trous, de manière, à ménager deux cavités cylindriques débouchant ("2"), imbriquées l'une dans l'autre, Sur le même plan de ses plus larges faces, un conduit d'admission(3),est percé d'un côté,entre les deux cylindres,deux autres conduits (4), sont percés à l'opposé, et débouchent chacun dans une cavitée, affecté à l'échappement. Le bloc peut être creux, muni de passages (5), destinés au liquide de refroidissement, ainsi que des différents trous, et filetages utiles à l'assemblage final.The engine essentially consists of:
a) A parallelepipedic block (1), consisting of a solid body, drilled and bored with two holes, so as to provide two cylindrical cavities emerging ("2"), nested one inside the other, On the same plane of its widest faces, an inlet duct (3), is drilled on one side, between the two cylinders, two other ducts (4), are drilled opposite, and each open into a cavity , assigned to the exhaust. The block may be hollow, provided with passages (5), intended for the coolant, as well as various holes, and threads useful for the final assembly.

b) De part et d'autre de ce bloc, deux culasses (6), sans joint, prenant en sandwich le bloc, ferment les deux cylindres ("2"). Chacune des culasses, est aménagée de façon à recevoir deux arbres tournants (7), les traversant totalement, dans l'axe de chacun des deux cylindres. b) On either side of this block, two cylinder heads (6), without seal, sandwiching the block, close the two cylinders ("2"). Each of the cylinder heads is arranged so as to receive two rotating shafts (7), completely passing through them, in the axis of each of the two cylinders.

Chaque culasse est usinée, de manière à permettre le passage, des liquides de refroidissement et de graissage, des rainures de transferts d'air (8), et de recevoir les accessoires tel que: bougie d'allumage (9), et injecteur (10), ainsi que les différents éléments de fixations et d'assemblages. Each cylinder head is machined, so as to allow the passage of coolants and lubricants, air transfer grooves (8), and to receive accessories such as: spark plug (9), and injector ( 10), as well as the various fasteners and assemblies.

c) A l'intérieur de chacun des deux cylindres ainsi clos, est logé un module tournant (11), parfaitement ajusté, fait d'un matériaux résistant adéquat, rendu solidaire des arbres. Les deux modules s'engrènent l'un dans l'autre, à la manière d'un engrenage, des chambres (2), y sont usinées sur le périmètre. c) Inside each of the two cylinders thus closed, is housed a rotating module (11), perfectly adjusted, made of an adequate resistant material, made integral with the trees. The two modules mesh with each other, like a gear, chambers (2) are machined there on the perimeter.

La forme de ses dentures, doit assurer un contact constant, à tout instant, au cours de leurs rotations, à la fois, au contact des cylindres, mais aussi entre les modules engrenés, de manière à permettre la meilleure étanchéité possible, celle-ci pouvant être améliorée grâce à une segmentation
Les deux modules comportent en outre, des pattes de graissage (12), et orifices de circulation d'huile sur leurs deux faces.The shape of its teeth, must ensure constant contact, at all times, during their rotations, both in contact with the cylinders, but also between the meshed modules, so as to allow the best possible seal, this can be improved by segmentation
The two modules also include lubrication lugs (12) and oil circulation orifices on their two faces.

L'agencement particulier du dispositif mécanique, assure le cycle moteur complet, au cours de la rotation des modules (11), ( qui est en sens inverse pour chacun ),en permettant de façon continue, le transit du comburant arrivant par le conduit(3),par l'intermédiaire des chambres (2),et des rainures (8), de la chambre d'admission (13), à la chambre de combustion (14), puis à démasquer après l'expansion, les orifices d'échappement (4), pour l'évacuation des gaz brûlés, tout en assurant, la fermeture étanche, des dites chambres entre elle à chaque cycle. The particular arrangement of the mechanical device ensures the complete engine cycle, during the rotation of the modules (11) (which is in the opposite direction for each), by allowing the transit of the oxidant arriving via the conduit (continuously). 3), via the chambers (2), and the grooves (8), from the intake chamber (13), to the combustion chamber (14), then to unmask after the expansion, the orifices d 'exhaust (4), for the evacuation of the burnt gases, while ensuring, the sealed closure, said chambers therebetween at each cycle.

A ltextérieur,deux pignons (17), solidaires des deux arbres(7), maintiennent les modules en bonne position, l'un par rapport à l'autre,et peuvent aussi servir de pompe à huile. Inside, two pinions (17), integral with the two shafts (7), hold the modules in good position, one with respect to the other, and can also serve as an oil pump.

FONCTIONNEMENT
Au départ,un démarreur électrique classique, fait tourner les arbres de sortie (7), ( par l'intermédiaire de la couronne dentée sur le volant(19), sur lesquels sont accouplés, tous les accessoires, tels que: pompe d'injection,de refroidissement,de graissage, alternateur, allumeur, compresseur volumique, (réglé à environ 10/1). Le compresseur volumique (18) ainsi sollicité, va produire de l'air comprimé, au taux de compression ordinaire d'un moteur classique, avec possibilité d'augmentation, si on le désire, cet air passant par le conduit (3), va alors attendre dans la chambre d'admission (13), que les deux modules (11), entraînés eux même, présentent la partie de leurs profils, (chambre (2) qui peut autoriser son passage, dans la chambre de combustion (14), et la remplir, durant tout le temps prés déterminé.OPERATION
At the start, a conventional electric starter, turns the output shafts (7), (via the ring gear on the flywheel (19), on which are coupled, all the accessories, such as: injection pump , cooling, lubrication, alternator, igniter, volume compressor (set to about 10/1). The volume compressor (18) thus requested, will produce compressed air at the ordinary compression ratio of a conventional engine. , with the possibility of increasing, if desired, this air passing through the conduit (3), will then wait in the intake chamber (13), that the two modules (11), driven themselves, have the part of their profiles, (chamber (2) which can authorize its passage into the combustion chamber (14), and fill it, during all the time pres determined.

Des rainures (8) dans les plants de culasse, assurent la continuité de l'admission, jusqu'au moment de la fermeture, à cet instant, la pompe à injection sollicitée, propulse, via l'injecteur(10), une dose de carburant dans la chambre de combustion (14). Presque simultanément la bougie d'allumage (9), (dans le cas de carburant explosif), produit son étincelle,ctest l'expansion.La pression ainsi obtenue, va s'exercer sur les dentures des modules (11), en les repoussant à ltopposé,la rotation s'effectue alors, jusqu'au moment où, ces même dentures,vont démasquer les orifices d'échappement (4), et recommencer une nouvelle admission d'air comprimé, qui, jusque à la fermeture de l'échappement, ira envahir la chambre (14), et parfaire l'échappement grâce à la rainure(8).  Grooves (8) in the breech plants, ensure the continuity of the admission, until the moment of closing, at this instant, the requested injection pump, propels, via the injector (10), a dose of fuel in the combustion chamber (14). Almost simultaneously the spark plug (9), (in the case of explosive fuel), produces its spark, this is the expansion. The pressure thus obtained, will be exerted on the teeth of the modules (11), pushing them back at the opposite end, the rotation then takes place, until the same teeth, unmask the exhaust orifices (4), and start a new admission of compressed air, which, until the closure of the exhaust, will invade the chamber (14), and perfect the exhaust thanks to the groove (8).

Le modèle ici présenté à titre d'exemple, offre 4 cavités utiles,soit 4 temps "moteur" pour un tour, chacune de ces chambres (13) (14) (15) (16) mobiles, représente un volume d'environ 25 cm3 à la pression atmosphérique; avec un rapport volumétrique de 10/1 nous obtenons: 250cm3 x 4 chambres = 1000 cm3,et cela à l'échelle du plan ci-joint. On peut ainsi comparer avec un moteur classique de 4 cylindres 1000cl3. Afin d'augmenter les performances, on peut empiler d'autres blocs(l) entre eux,et en déphasant les modules(11), de manière à produire une explosion à l'un, pendant que l'autre est en admission,ainsi il n'y a aucun temps mort, on obtient une rotation entretenue constante avec augmentation considérable de la puissance.  The model presented here as an example, offers 4 useful cavities, ie 4 "engine" times for one revolution, each of these mobile chambers (13) (14) (15) (16), represents a volume of approximately 25 cm3 at atmospheric pressure; with a volumetric ratio of 10/1 we obtain: 250cm3 x 4 chambers = 1000 cm3, and this on the scale of the attached plan. We can thus compare with a conventional 4-cylinder 1000cl3 engine. In order to increase performance, other blocks (l) can be stacked together, and by phase shifting the modules (11), so as to produce an explosion for one, while the other is in admission, as well there is no dead time, a constant sustained rotation is obtained with a considerable increase in power.
