Abstract

The invention concerns a novel technique for making piston-powered heat engines. The novel engine comprises several matched pistons (26) secured by piston rods (23) articulated with several cranks (16). Each crank (16) is coupled to an outer pedal disc (18) and an inner pedal disc (17). The pedal disc-crank assemblies (16) directly transform the sinusoidal movements of the piston rods (23) into a rotational movement received by the drive gears (25) and powering movement (24) transmitted to the flywheel. The piston rod (23) provides transmission of forces required for moving the pistons with minimum energy loss. Said inventive novel internal combustion heat engine is perfectly suited to existing fuels and is particularly designed for the automotive industry, the aircraft industry, and the shipbuilding industry.

Ce nouveau type de moteur thermique à pistons multicylindres permet un accroissement de la performance , du rendement et de la longévité du moteur . Elle apporte principalement une innovation à la technique énoncéeThe invention relates to a combustion engine with internal combustion, semi-rotary and double pedal discs.

Une partie de la technique énoncée dans la dite demande a été reprise et réutilisée dans la conception de ce nouveau moteur.5 in the international application number PCT / IB2004 / 000460 filed February 24, 2004 by the same inventor. Part of the technique stated in the said application has been taken up and reused in the design of this new engine.
Les moteurs conventionnels sont généralement constitués de plusieurs pistons (26) accouplés au vilebrequin à l'aide de bielles. Le vilebrequin prolongé par le volantConventional engines generally consist of several pistons (26) coupled to the crankshaft using connecting rods. The crankshaft extended by the steering wheel
10 moteur tourne autour d'un axe fixe sur lequel il prend plusieurs points d'appui constitués par les paliers. Dans ce type de moteurs, l'explosion qui se produit dans un cylindre entraîne la rotation du vilebrequin , et ce dernier déplace à son tour des pistons (26) pour terminer le cycle ( échappement , admission , compression ). Le volant moteur assure la transmission du mouvement de rotation vers la boîte de vitesse.10 motor rotates about a fixed axis on which it takes several points of support constituted by the bearings. In this type of engine, the explosion that occurs in a cylinder causes the crankshaft to rotate, and the crankshaft in turn moves pistons (26) to complete the cycle (exhaust, intake, compression). The flywheel transmits the rotational movement to the gearbox.
15 Dans le fonctionnement de ce type de moteur, la direction de la force délivrée par l'explosion est toujours dans le sens opposé à celle requise par la compression et nécessite une réorientation , constituant une source supplémentaire de frottement. Le mouvement pendulaire oscillatoire des bielles autour des axes à piston entraîne également une perte d'énergie importante en même temps qu'un frottement considérable provoquant une usureIn the operation of this type of engine, the direction of the force delivered by the explosion is always in the opposite direction to that required by the compression and requires reorientation, constituting an additional source of friction. Oscillatory pendulum movement of the connecting rods around the piston pins also results in a significant loss of energy at the same time as considerable friction causing wear.

De plus, l'adoption d'un cylindre à grande section s'impose pour avoir un taux de compression très élevé, à moins d'utiliser un turbocompresseur.Premature piston liners, segments, pistons (26) and bearings. In addition, the adoption of a large section cylinder is required to have a very high compression rate, unless using a turbocharger.
Plusieurs innovations ont été apportées à cette technique de fabrication afin d'optimiser la consommation d'énergie mais des problèmes restent toujours à résoudre .Several innovations have been made to this manufacturing technique to optimize energy consumption, but problems remain to be solved.
25 Dans la demande JP 08200498 A du 06 Août 1986 , les frottements sont fortement réduits, mais si les pistons s'immobilisent au milieu de leur course à l'arrêt du moteur , le redémarrage de celui-ci devient impossible . Par contre , les demandes US 5.826.550 du 27 Octobre 1998 , US 5.782.213 du 21 Juillet 1998 , US 2002/0166521 Al du 14 Novembre 2002 proposent des solutions permettant de remédier à cet inconvénient maisIn the application JP 08200498 A of August 06, 1986, the friction is greatly reduced, but if the pistons come to a standstill in the middle of their stroke when the engine is stopped, the restarting of the latter becomes impossible. On the other hand, the applications US 5,826,550 of October 27, 1998, US 5,782,213 of July 21, 1998, US 2002/0166521 A1 of November 14, 2002 propose solutions to remedy this drawback but
30 nécessitent une disposition perpendiculaire des couples de pistons compliquant ainsi leur agencement dans leur compartiment. La présente invention propose une solution technique permettant de résoudre simultanément ces deux inconvénients .30 require a perpendicular arrangement of the pairs of pistons thus complicating their arrangement in their compartment. The present invention proposes a technical solution for simultaneously solving these two disadvantages.
L'astuce consiste à trouver un mécanisme permettant de recueillir les mouvements rectilignes sinusoïdaux des pistons (26) et de les transformer en des mouvements de rotation tout en minimisant les pertes d'énergie et de garantir la réciprocité de la transformation .The trick is to find a mechanism to collect sinusoidal rectilinear motions of the pistons (26) and transform them into rotational movements while minimizing energy losses and ensuring reciprocity of transformation.
Pour comprendre l'objet de l'invention , on va prendre un ensemble de pédales de bicyclette avec son développement et on va le disposer verticalement , c'est à dire une pédale en haut (1) et la pédale opposée (2) en bas. Si on fait tourner cet ensemble autour de son axe habituel et qu'on anime son axe de rotation d'un mouvement circulaire de sens contraire et de même vitesse angulaire, de rayon (5) égal à la longueur d'une pédale et centré sur le point de départ de la pédale inférieure , les deux mouvements étant contenus dans le même plan , on constatera que les deux extrémités des pédales suivront des trajectoires rectilignes, perpendiculaires l'une à l'autre . Les dessins annexés à ce dossier nous permettront de comprendre en détail les principes de fonctionnement de ce nouveau type de moteur. Ces dessins expliquent progressivement le détail de chaque pièce constitutive du moteur pour aboutir à la constitution d'un moteur complet.To understand the object of the invention, we will take a set of bicycle pedals with its development and we will arrange it vertically, ie a pedal at the top (1) and the opposite pedal (2) at the bottom . If this assembly is rotated around its usual axis and its axis of rotation is animated by a circular movement of opposite direction and of the same angular velocity, radius (5) equal to the length of a pedal and centered on the starting point of the lower pedal, the two movements being contained in the same plane, it will be seen that the two ends of the pedals will follow rectilinear trajectories, perpendicular to each other. The drawings attached to this file will allow us to understand in detail the principles of operation of this new type of engine. These drawings progressively explain the detail of each constituent part of the engine to result in the constitution of a complete engine.
La figure 1 illustre une représentation schématique dans un plan, d'un ensemble de pédales et développement de bicyclette tournant autour de son axe de rotation habituel, lequel est animé d'un mouvement circulaire.Figure 1 illustrates a schematic representation in a plane of a set of pedals and bicycle development rotating about its usual axis of rotation, which is animated by a circular motion.

La figure 3 représente une vue semi-éclatée d'un ensemble de manivelles (16) avec un disque à pédale (17) interne et un disque à pédale externe (18). La figure 4 représente une vue en perspective d'un demi-moteur sans les chemises à piston (30) .Figure 3 shows a semi-exploded view of a set of cranks (16) with an internal pedal disc (17) and an external pedal disc (18). Fig. 4 is a perspective view of a half-motor without the piston liners (30).
La figure 5 représente une vue en perspective d'un moteur entier sans les chemises à piston (30) .Figure 5 shows a perspective view of an entire engine without the piston liners (30).
La figure 6 représente une vue en perspective d'un moteur complet. En référence à ces dessins, le nouveau moteur comporte plusieurs pistons (26) appariés, plusieurs tiges à piston (23) solidarisant chaque couple de pistons (26), plusieurs disques à pédale et des manivelles (16) articulées avec les tiges à pistons (23) et avec les fausses tiges à piston (27), des engrenages d'entraînement (25) et d'extraction de puissance (24).Figure 6 shows a perspective view of a complete engine. With reference to these drawings, the new engine comprises a plurality of pistons (26) matched, several piston rods (23) solidarisant each pair of pistons (26), several pedal discs and cranks (16) articulated with the piston rods ( 23) and with the false piston rods (27), drive gears (25) and power extraction gears (24).
Dans la présentation illustrée en figure 1 , l'ensemble pédales et développement de bicyclette se trouve dans sa position de départ. L'extrémité de la pédale inférieure (2) se déplacera initialement de la gauche vers la droite tandis que l'extrémité de la pédale supérieure (1) va se déplacer de haut en bas. Il faut noter que ces deux extrémités de pédales resteront sur des trajectoires rectilignes (8) pendant leur mouvement sinusoïdaux. Le sens de déplacement (10) de la pédale inférieure est perpendiculaire au sens de déplacement (9) de la pédale supérieure. Le sens de rotation (6) de l'ensemble pédales et développement de bicyclette est contraire au sens de rotation de l'aiguille d'une montre, tandis que le sens (11) du mouvement circulaire qu'on va imposer à son axe de rotation est identique à celui de l'aiguille d'une montre. L'extrémité de la pédale inférieure (2), au début de son mouvement, se trouve au centre de la trajectoire circulaire (7) de l'ensemble pédales et développement de bicyclette, et le rayon (5) de la dite trajectoire circulaire (7) est égal à la longueur d'une pédale. Cette trajectoire circulaire est également centrée sur le point d'intersection des deux trajectoires rectilignes des extrémités de pédales qui sont perpendiculaires entre elles. Pour conclure cette explication, il faut remarquer que l'extrémité d'une pédale suit une trajectoire rectiligne perpendiculaire à la trajectoire rectiligne de l'extrémité de la pédale opposée même si l'ensemble pédales et développement s'anime d'un mouvement de rotation combiné à un mouvement circulaire. Il ressort de cette étude théorique que la combinaison d'un mouvement de rotation et d'un mouvement circulaire permet, sous certaines conditions, d'obtenir deux mouvements rectilignes sinusoïdaux et réciproquement.In the presentation illustrated in FIG. 1, the pedals and bicycle development assembly is in its starting position. The end of the bottom pedal (2) will initially move from left to right while the end of the upper pedal (1) will move up and down. It should be noted that these two ends of pedals will remain on rectilinear trajectories (8) during their sinusoidal movement. The direction of movement (10) of the lower pedal is perpendicular to the direction of movement (9) of the upper pedal. The direction of rotation (6) of the pedal assembly and bicycle development is contrary to the direction of rotation of the hand of a watch, while the direction (11) of the circular movement that will be imposed on its axis of rotation is identical to that of the hand of a watch. The end of the lower pedal (2), at the beginning of its movement, is in the center of the circular trajectory (7) of the pedals and bicycle development assembly, and the radius (5) of the said circular trajectory ( 7) is equal to the length of a pedal. This circular trajectory is also centered on the point of intersection of the two rectilinear paths of the ends of pedals which are perpendicular to each other. To conclude this explanation, it should be noted that the end of a pedal follows a rectilinear trajectory perpendicular to the rectilinear trajectory of the end of the opposite pedal even if the whole pedals and development comes alive with a rotational movement combined with a circular motion. It emerges from this theoretical study that the combination of a rotational movement and a circular movement allows, under certain conditions, to obtain two rectilinear sinusoidal movements and vice versa.
Le choix de l'exemple d'un ensemble pédales et développement de bicyclette nous a seulement facilité la compréhension du principe de base de l'invention. Mais pour la production du moteur, l'ensemble pédales et développement sera remplacé par la manivelle (16) et l'utilisation d'un disque à pédale permet d'imposer à la manivelle (16) une trajectoire circulaire. Trois disques à pédales disposés parallèlement seront utilisés pour chaque demi-moteur, entre lesquelles se placeront deux manivelles (16). La manivelle (16) possède une forte ressemblance à une portion de vilebrequin dont elle assure le rôle ( voir figure 2). Elle est munie de deux axes à tige et de deux axes à disques, qui s'intercalent entre eux. L'axe à tige interne (12) s'articule avec une tige à piston (23) tandis que l'axe à tige externe (13) s'articule avec une fausse tige à piston (27). L'axe à disque interne (14) s'articule avec un disque à pédale externe(18) tandis que l'axe à disque externe (15) s'articule avec un disque à pédale interne (17).The choice of the example of a pedal assembly and bicycle development has only facilitated the understanding of the basic principle of the invention. But for the production of the engine, the pedal assembly and development will be replaced by the crank (16) and the use of a pedal disc allows to impose the crank (16) a circular path. Three parallel pedal discs will be used for each half-motor, between which will be placed two cranks (16). The crank (16) has a strong resemblance to a portion of crankshaft which it ensures the role (see Figure 2). It is equipped with two rod shafts and two disk shafts, which are interposed between them. The shaft with internal shaft (12) is articulated with a rod piston (23) while the outer shaft axis (13) is articulated with a false piston rod (27). The internal disk axis (14) articulates with an external pedal disk (18) while the outer disk axis (15) articulates with an internal pedal disk (17).
L'illustration représentée par la figure 3 constitue l'essentiel dans la compréhension du fonctionnement du nouveau moteur. Le sens de rotation de chaque pièce a été rajouté sur la figure. On a volontairement caché un disque à pédale externe (18) et les deux tiges à piston (23) pour le rendre plus lisible. Le sens de rotation (20)des disques à pédale disposés parallèlement est contraire au sens de rotation (19)de ses manivelles .L'axe à tige interne (12) situé en haut entamera une descente dès le début d'une rotation tandis que l'axe à tige interne (12) situé en bas remontera. Les deux axes à tige internes (12)suivront deux trajectoires rectilignes perpendiculaires entre elles. Les trois disques à pédale d'un demi- moteur sont disposés parallèlement et tournent dans le même sens (20) et à la même vitesse angulaire . Les deux manivelles(16) d'un demi-moteur tournent également à la même vitesse angulaire et dans le même sens (19), qui est contraire au sens de rotation (20) des disques à pédale. Le disque à pédale interne d'un demi-moteur se place entre ses deux disques à pédale externes. Le disque à pédale externe (18) est un disque muni d'un engrenage (22) et d'un axe à manivelle (21) au niveau duquel s'articule l'axe à disque interne (14) de la manivelle (16). Le disque à pédale interne (17) est identique au disque à pédale externe (18) sauf qu'il est muni de deux axes à manivelles (21) diamétralement opposés. Chaque disque à pédale est logé dans la cage interne d'un roulement à galets. Les disques à pédale imposent une trajectoire circulaire aux axes à disque des manivelles (16) . Par ailleurs , ils assurent la capture et la transmission de la puissance délivrée par les pistons (26) en phase d'explosion dans le cycle moteur.The illustration shown in Figure 3 is essential in understanding the operation of the new engine. The direction of rotation of each piece has been added to the figure. An external pedal disk (18) and the two piston rods (23) have been deliberately hidden to make it more legible. The direction of rotation (20) of the pedal disks arranged in parallel is opposite to the direction of rotation (19) of its cranks. The internal shaft axis (12) located at the top will start a descent from the beginning of a rotation while the shaft with internal rod (12) located at the bottom will go up. The two internal rod axes (12) will follow two rectilinear paths perpendicular to each other. The three pedal discs of a half motor are arranged in parallel and rotate in the same direction (20) and at the same angular speed. The two cranks (16) of a half-motor also rotate at the same angular speed and in the same direction (19), which is contrary to the direction of rotation (20) of the pedal discs. The internal pedal disk of a half-motor is placed between its two external pedal discs. The outer pedal disc (18) is a disc having a gear (22) and a crank pin (21) at which the internal disc axis (14) of the crank (16) is articulated. . The internal pedal disk (17) is identical to the outer pedal disc (18) except that it is provided with two diametrically opposed crank axes (21). Each pedal disc is housed in the inner race of a roller bearing. The pedal discs impose a circular path to the disc axes of the cranks (16). In addition, they ensure the capture and transmission of the power delivered by the pistons (26) in the explosion phase in the engine cycle.
La figure 4 est une continuation de la figure 3 sur laquelle on a fait apparaître les deux tiges à piston (23) et le second disque à pédale externe (18) . Les sens de déplacement (29) des tiges à pistons ont été rajoutés sur la figure pour faciliter la compréhension . La tige à piston (23) est une tige rectangulaire munie d'un axe à manivelle en son point médiane , au niveau duquel s'articule l'axe à tige interne (12) d'une manivelle (16). Sur ses deux extrémités se trouvent deux pistons (26) qui lui sont solidaires. La tige à piston (23) assurent la capture et la transmission de l'énergie libérée par les pistons (26) en phase d'explosion vers les disques à pédales via la manivelle (16) et vers les pistons (26) en phase de compression ou en phase d'échappement dans le cycle moteur. Elle remplace la bielle dans le moteur conventionnel.FIG. 4 is a continuation of FIG. 3 on which the two piston rods (23) and the second external pedal disk (18) have been shown. The directions of movement (29) of the piston rods have been added to the figure to facilitate understanding. The piston rod (23) is a rectangular rod provided with a crank pin at its midpoint, at which the internal shaft axis (12) of a crank (16) is articulated. On both ends are two pistons (26) which are integral. The piston rod (23) ensures the capture and transmission of the energy released by the pistons (26) in the explosion phase to the pedal discs via the crank (16) and to the pistons (26) in the compression phase or in the exhaust phase in the engine cycle. It replaces the connecting rod in the conventional engine.
La figure 5 nous montre un moteur entier sans les chemises à pistons (30) . Sur cette figure apparaissent la fausse tige à piston (27) et les deux engrenages d'entraînement (25) et de puissance (24). Le sens de déplacement (28) de la fausse tige à piston y a été rajouté. La fausse tige à piston (27) est une tige rigide rectangulaire munie de deux axes à manivelle à ses deux extrémités, au niveau desquelles s'articulent deux axes à tige externe (13) de deux manivelles (16). Elle assurent la transmission d'une partie de l'énergie captée par une manivelle (16) vers l'autre manivelle (16) qui lui est articulée. L'engrenage de puissance (24) et l'engrenage d'entraînement (25) assurent la synchronisation de la rotation des disques à manivelle et permettent également l'extraction de la puissance délivrée par le moteur. Il faut noter que le sens de rotation des disques à pédale d'un demi-moteur est contraire au sens de rotation des disques à pédale de l'autre demi-moteur qui lui est associé. Selon la mode de réalisation illustrée en figure 6 , qui constitue la mode de réalisation préférentielle, le nouveau moteur comporte huit pistons (26) accouplés deux par deux et reliés par quatre tiges à pistons (23) , lesquelles s'articulent avec quatre manivelles (16) au niveau des axes à tige internes (12) de quatre manivelles (16). Une fausse tige (27) à piston s'articule avec les deux axes à tiges externe (13) de deux manivelles (16) , tandis qu'une autre fausse tige à piston (27) s'articule avec les deux axes à tiges externes (13) restant. Les deux axes à disque externes (15) des deux manivelles (16) d'un demi-moteur s'articulent avec le même disque à pédale interne (17) , tandis que les deux axes à disque externe (15) de l'autre demi-moteur s'articule avec un autre disque à pédale interne (17) . Chaque axe à disque interne (14) d'une manivelle (16) est articulée avec l'axe à manivelle (21) d'un disque à pédale externe (18) . Chaque disque à pédale s'articule avec un engrenage de puissance (24) ou avec un engrenage d'entraînement (25) pour assurer la synchronisation de sa rotation avec les autres disques à manivelles . Les disques à pédale d'un demi-moteur tournent dans le même sens, qui est contraire au sens de rotation des disques à pédale du demi-moteur qui lui est associé. Par ailleurs , le sens de rotation des manivelles (16) d'une demi-moteur est contraire au sens de rotation de ses disques à pédale. Une autre mode de réalisation non illustrée contient un moteur sans l'engrenage d'entraînement pour alléger le moteur, et où les disques à pédale de chaque demi-moteur entrent en contact direct avec les disques à pédale de l'autre demi-moteur.Figure 5 shows an entire engine without the piston liners (30). In this figure appear the false piston rod (27) and the two drive gears (25) and power (24). The direction of movement (28) of the false piston rod has been added. The false piston rod (27) is a rectangular rigid rod provided with two crank axes at both ends, at which two axes with external rod (13) of two cranks (16) are articulated. They ensure the transmission of a portion of the energy captured by a crank (16) to the other crank (16) articulated thereto. The power gear (24) and the drive gear (25) synchronize the rotation of the crank discs and also allow the extraction of power delivered by the motor. It should be noted that the direction of rotation of the pedal discs of a half-motor is contrary to the direction of rotation of the pedal discs of the other half-motor associated therewith. According to the embodiment illustrated in FIG. 6, which constitutes the preferred embodiment, the new motor comprises eight pistons (26) coupled in pairs and connected by four piston rods (23), which articulate with four cranks ( 16) at the inner shaft pins (12) of four cranks (16). A piston rod (27) is articulated with the two outer shaft pins (13) of two cranks (16), while another piston rod (27) is articulated with the two outer shaft pins. (13) remaining. The two outer disk shafts (15) of the two cranks (16) of a half-motor articulate with the same internal pedal disk (17), while the two outer-disk shafts (15) of the other half motor is articulated with another internal pedal disc (17). Each internal disk axle (14) of a crank (16) is articulated with the crank pin (21) of an outer pedal disc (18). Each pedal disc articulates with a power gear (24) or a drive gear (25) to synchronize its rotation with other crank discs. The pedal discs of a half-motor rotate in the same direction, which is contrary to the direction of rotation of the pedal discs of the half-motor associated therewith. Furthermore, the direction of rotation of the cranks (16) of a half-motor is contrary to the direction of rotation of its pedal discs. Another non-illustrated embodiment contains a motor without the drive gear for lightening the engine, and wherein the pedal discs of each half-motor come into direct contact with the pedal discs of the other half-motor.
Ce nouveau moteur peut contenir également un nombre de piston supérieur à huit. Par ailleurs , une autre forme de réalisation consiste à mettre tous les pistons sur un même plan. L'épaisseur du moteur se réduit fortement dans ce cas .This new engine may also contain a piston number greater than eight. Furthermore, another embodiment consists in putting all the pistons on the same plane. The thickness of the engine is greatly reduced in this case.
A titre d'exemple non limitatif, un moteur de ce type et à huit cylindres, avec un alésage de 70mm et un taux de compression de dix, aura une dimension de l'ordre de 58 cm pour la longueur , de 45 cm pour la largeur , et de 45 cm pour la hauteur . Le nouveau moteur, selon l'invention, est destiné à tout type de moteur thermique à combustion interne fonctionnant aux combustibles existants et utilisé dans l'industrie automobile, dans l'industrie aéronautique et dans l'industrie maritime. By way of non-limiting example, a motor of this type and eight cylinders, with a bore of 70mm and a compression ratio of ten, will have a dimension of about 58 cm for the length, 45 cm for the width, and 45 cm for the height. The novel engine, according to the invention, is intended for any type of internal combustion engine operating on existing fuels and used in the automotive industry, in the aviation industry and in the maritime industry.
