The cylinder and the piston are equipped with flat surface and their axes are continuous, if formed of cubical shape.

Description

1 28588281 2858828

L'invention présentée ci-après, est mécanisme de cylindre et piston rotatif pour différents types de moteurs à combustion interne et des pompes rotatives.  The invention presented hereinafter is cylinder mechanism and rotary piston for various types of internal combustion engines and rotary pumps.

On constate une perte de l'énergie (sous forme d'inertie) dans les mécanismes alternatifs ou les mécanismes courants. La raison de cette perte est le mouvement linéaire du piston à l'intérieur du cylindre, dans les deux extrémités de la trajectoire de piston (les points morts ou les points d'arrêts de piston).  There is a loss of energy (in the form of inertia) in the alternative mechanisms or the current mechanisms. The reason for this loss is the linear movement of the piston inside the cylinder, in both ends of the piston path (dead points or piston stops).

La plupart des concepts de moteurs rotatifs présentés à ce jour, ont des problèmes d'étanchéité, d'usures, de combustion incomplète entre autres problèmes empêchant leur évolution. Le mécanisme de cette invention a la particularité de non seulement supprimer les points morts (les points d'arrêts de piston) mais aussi de régler les problèmes de perte d'énergie, d'usure, d'étanchéité et de combustion incomplète.  Most of the concepts of rotary engines presented to date, have problems of sealing, wear, incomplete combustion and other problems preventing their evolution. The mechanism of this invention has the particularity of not only eliminating dead spots (piston stopping points) but also of solving the problems of energy loss, wear, sealing and incomplete combustion.

Le principe de cette invention est basé sur la trajectoire d'une roue crantée (à cran interne) autour d'une roue crantée (à cran simple). Le nombre de crans de la roue crantée interne est 2X celui de la roue simple. Si on considère que la roue simple ne tourne pas (fixe), on constatera que la roue interne, en plus de son mouvement excentrique autour de la roue simple, effectuera aussi un demi tour axial. La manière des rotations de la roue (à cran interne) et sa position par rapport à l'autre roue (simple), simule la position de cylindre et piston ainsi que le type de leur rotation.  The principle of this invention is based on the trajectory of a notched wheel (internal notched) around a notched wheel (single notch). The number of notches of the internal toothed wheel is 2X that of the single wheel. If we consider that the single wheel does not rotate (fixed), we will see that the internal wheel, in addition to its eccentric movement around the single wheel, will also perform an axial half turn. The way the wheel rotates (internal notch) and its position relative to the other wheel (simple), simulates the position of cylinder and piston as well as the type of their rotation.

On peut créer ce mécanisme avec 4 compositions différentes, cylindre et piston sont tous les deux à rotation et révolution. Ces quatre compositions comprennent 2 formes physiques basées chacune sur 2 méthodes de rotation différentes: 1- Cylindre et piston cubique avec la méthode "cylindre excentrique" 2- Cylindre et piston cylindrique avec la méthode "cylindre excentrique" 3- Cylindre et piston cubique avec la méthode "piston excentrique" 4- Cylindre et piston cylindrique avec la méthode "piston excentrique" Dans la méthode cylindre excentrique, le mouvement du piston est autour de son axe central mais le cylindre a les 2 mouvements axial et excentrique. Le rapport de ces mouvements rotatifs et excentriques est de 1 à 2, ce qui veut dire à chaque 2 tours excentriques autour de l'axe central du piston, il y a aussi un tour axial. Le rapport entre le mouvement axial du piston et cylindre est égal.  We can create this mechanism with 4 different compositions, cylinder and piston are both rotating and revolution. These four compositions comprise 2 physical forms each based on 2 different rotation methods: 1- Cylinder and cubic piston with the "eccentric cylinder" method 2- Cylinder and cylindrical piston with the "eccentric cylinder" method 3- Cylinder and cubic piston with the method "eccentric piston" 4- Cylinder and cylindrical piston with the method "eccentric piston" In the eccentric cylinder method, the movement of the piston is around its central axis but the cylinder has both axial and eccentric movements. The ratio of these rotary and eccentric movements is 1 to 2, which means that every 2 eccentric turns around the central axis of the piston, there is also an axial rotation. The ratio between the axial movement of the piston and cylinder is equal.

2 2858828 Dans la méthode piston excentrique, le mouvement du cylindre est autour de son axe central mais le piston a les 2 mouvements axial et excentrique. Le rapport de ces mouvements rotatif et excentrique est de 1 à 2, ce qui veut dire que tous les deux tours excentriques autour de l'axe central du piston, se produit aussi un tour axial. Le rapport entre le mouvement axial du cylindre et piston est égal. La combinaison des deux mouvements rotatif et excentrique dans le cylindre et piston produit le mouvement du piston tout au long du cylindre. Cela créera la situation idéale pour les 4 temps: admission, compression, combustion et échappement.  In the eccentric piston method, the movement of the cylinder is around its central axis but the piston has both axial and eccentric movements. The ratio of these rotary and eccentric movements is 1 to 2, which means that every two eccentric turns around the central axis of the piston, also occurs an axial turn. The ratio between the axial movement of the cylinder and piston is equal. The combination of the two rotary and eccentric movements in the cylinder and piston produces the movement of the piston throughout the cylinder. This will create the ideal situation for the 4-stroke: intake, compression, combustion and exhaust.

Les autres éléments de ce mécanisme, tels carburateur, électricité, les entrées et sorties des gaz et les soupapes dans son usage en tant que moteur, seront une combinaison des deux méthodes rotative ou classique. Par exemple l'ensemble des soupapes peuvent s'ouvrir, se fermer et contrôler l'entrée et sortie des gaz, en même temps qu'il tourne avec le cylindre et piston.  The other elements of this mechanism, such as carburetor, electricity, gas inlets and outlets and valves in its use as a motor, will be a combination of both rotary or conventional methods. For example all the valves can open, close and control the entry and exit of gases, while it rotates with the cylinder and piston.

Dans ce mécanisme, en plus de la surface idéale permettant l'insertion de nombreux segments d'étanchéité de cylindre et piston, il n' y a aucune limitation sur la longueur de course du piston à l'intérieur du cylindre. Au de besoin on peut avoir une longueur de course plusieurs fois le diamètre du piston.  In this mechanism, in addition to the ideal surface for the insertion of numerous cylinder and piston seal segments, there is no limitation on the stroke length of the piston within the cylinder. If necessary we can have a stroke length several times the diameter of the piston.

Les figures jointes montrent les détails de cette invention sur le plan physique aussi bien que technique.  The accompanying figures show the details of this invention physically as well as technically.

3 2858828 Fig.9 (Abrégé) Montre les différentes façons de mouvement de cylindre et piston sous forme de cylindre et piston excentrique. Si on suppose que la roue (02) est fixée à sa place et ne tourne pas, en tournant la roue (01) de façon axiale autour de celle-ci, on constatera que du point de vue du mouvement, les rotations de cylindre et piston, chacun dans la méthode excentrique sont respectivement exactement comme les rotation de la roue (01) autour de la roue (02), et puisqu' à chaque tour effectué elle fait aussi un demi tour sur son axe central, le diamètre (07) sera toujours tangent avec le point (05). Par conséquent la ligne (07) sera la longueur de la trajectoire du cylindre du piston.  Fig. 9 (Short) Shows the different ways of cylinder and piston movement in the form of cylinder and eccentric piston. If it is assumed that the wheel (02) is fixed in its place and does not rotate, by turning the wheel (01) axially around it, it will be seen that from the point of view of the movement, the cylinder rotations and piston, each in the eccentric method are respectively exactly like the rotation of the wheel (01) around the wheel (02), and since each turn made it also makes a half turn on its central axis, the diameter (07) will always be tangent with the point (05). Therefore the line (07) will be the length of the trajectory of the piston cylinder.

Les points (05) et (06) sur les cercles centraux (03) et (04) seront les centres axiaux de cylindre et piston (selon les méthodes choisies: piston et cylindre excentrique) et du point de vue du calcul, on peut dire que le rapport entre les deux roues (01) et (02) est de 2 à 1. La longueur de la ligne (07) (entre les points (05) et (06)) est égale à la longueur de course et 4X la longueur d'excentrique de la pièce excentrique (cylindre ou piston).  The points (05) and (06) on the central circles (03) and (04) will be the axial centers of cylinder and piston (according to the chosen methods: piston and eccentric cylinder) and from the point of view of calculation, we can say that the ratio between the two wheels (01) and (02) is 2 to 1. The length of the line (07) (between the points (05) and (06)) is equal to the stroke length and 4X la eccentric length of the eccentric piece (cylinder or piston).

Si on employait le cylindre ou le piston en tant que pièce centrale (05), ils n'auraint qu'un mouvement de rotation axiale, tandis que l'autre pièce (06), en plus de son mouvement de rotation au rapport égal à la pièce centrale, aura aussi un mouvement excentrique au rapport double (200%) de son mouvement axial.  If the cylinder or the piston was used as a central part (05), they only had axial rotational movement, while the other part (06), in addition to its rotational movement at the ratio equal to the central piece, will also have an eccentric movement to double ratio (200%) of its axial movement.

La forme apparente de cylindre et piston, n'a aucune limitation particulière, cependant, techniquement pour des questions de production et de rentabilité, deux formes générales "Cubique" et "Cylindrique" sont proposées.  The apparent shape of cylinder and piston, has no particular limitation, however, technically for issues of production and profitability, two general forms "Cubic" and "Cylindrical" are proposed.

Dans la forme cubique, le cylindre (16) et le piston (13), sont dotés de plusieurs surfaces plates qui faciliteront la création des rainures (14) permettant l'insertion des segments d'étanchéités et l'huilage (11)-(12). Ces segments (en carbone, céramique ou alliages en acier) assurent non seulement l'étanchéité et l'huilage, mais aussi séparent les deux chambres de combustion (21)-(22) dans les deux extrémités de piston.  In the cubic form, the cylinder (16) and the piston (13) are provided with a plurality of flat surfaces which will facilitate the creation of the grooves (14) for the insertion of the seal segments and the oiling (11) - ( 12). These segments (carbon, ceramic or alloy steel) not only seal and oil, but also separate the two combustion chambers (21) - (22) in both piston ends.

Sur l'axe central (20), en plus du piston (13), il y a aussi deux plaques (18), qui fermeront les deux côtés du cylindre. Ces deux plaques (18), qui tourne avec le cylindre et piston, 4 2858828 limiteront les côtés du cylindre. Sur les surfaces internes de ces plaques (18), il y aura des rainures (19) qui assureront des mouvements tiroir accompagnant les rotations de cylindre et piston. L'ensemble entrée-sortie des gaz (25)(26) et les soupapes (29)-(30) sera placé sur une de ces deux plaques.  On the central axis (20), in addition to the piston (13), there are also two plates (18), which will close both sides of the cylinder. These two plates (18), which rotates with the cylinder and piston, 4 2858828 will limit the sides of the cylinder. On the inner surfaces of these plates (18), there will be grooves (19) which will provide drawer movements accompanying the cylinder and piston rotations. The gas inlet-outlet assembly (25) (26) and the valves (29) - (30) will be placed on one of these two plates.

Dans la forme cylindrique, le cylindre (36) a la forme d'un cylindre creux et le piston (33) la forme d'un cylindre plein. Sur la surface de piston (33), il y a des rainures (34) qui permettent l'insertion des segments d'étanchéités et l'huilage (35).  In the cylindrical form, the cylinder (36) is in the form of a hollow cylinder and the piston (33) is in the form of a solid cylinder. On the piston surface (33) there are grooves (34) which allow the insertion of the sealing rings and the oiling (35).

Il est tout à fait possible d'avoir deux ou plusieurs cylindres et pistons fonctionnant ensemble et la plaque (37) conçue à cet effet portera l'ensemble des cylindres en un seul bloc. Cette plaque est placée sur l'axe central (20) et tourne avec cet ensemble.  It is quite possible to have two or more cylinders and pistons operating together and the plate (37) designed for this purpose will carry all the cylinders in one block. This plate is placed on the central axis (20) and rotates with this set.

Grâce à la forme apparente et l'absence de mouvement non linéaire de la bielle (38), on peut utiliser l'espace qui se trouve des deux côtés du piston et par conséquent au besoin, comme c'est le cas du cylindre et piston cubique, on peut profiter des 2 chambres à combustion (21)-(22) se trouvant des deux extrémités de piston. Une autre particularité de ce type de bielle (38) est qu'on peut employer une bielle et un cylindre plus longs et y apporter des mouvements de courses plus longues.  Due to the apparent shape and absence of non-linear movement of the connecting rod (38), it is possible to use the space on both sides of the piston and consequently, as is the case with the cylinder and piston cubic, we can take advantage of the 2 combustion chambers (21) - (22) located at both ends of the piston. Another peculiarity of this type of rod (38) is that a longer rod and a longer cylinder can be used and make longer strokes.

Afin de maîtriser un contrôle précis concernant les rapports de rotation axial et excentrique, un mécanisme (40)-(28) a été prévu. Ce mécanisme s'installe sur l'ensemble et se joint au cylindre ou piston à rotation excentrique, à l'aide des pièces (27) et (39).  In order to control precise control of axial and eccentric rotation ratios, a mechanism (40) - (28) has been provided. This mechanism is installed on the assembly and joins the cylinder or piston eccentric rotation, using parts (27) and (39).
