This rotor with blades has no component to be driven apart from the various pumps for cooling or lubrication. The application of the invention relates to the automotive and motor cycle industries.

Description

MOTEUR A EXPLOSIONS CIRCULAIRE AVEC CHAMBRES
DE COMBUSTION A VOLUME VARIABLE
La présente invention concerne les moteurs à explosions fonctionnant avec un mélange d'air et d'essence. On connait à l'heure actuelle trois sortes de moteur ; le 4 temps, avec ou sans turbo, le 2 temps et le rotatif.CIRCULAR EXPLOSION ENGINE WITH CHAMBERS
VARIABLE VOLUME COMBUSTION
The present invention relates to explosion engines operating with a mixture of air and gasoline. Three kinds of engine are currently known; 4 stroke, with or without turbo, 2 stroke and rotary.

le 4 temps présente l'inconvénient d'être obligé de faire deux tours de moteur pour obtenir une explosion, avec en plus beaucoup de pièces en mouve- ment, donc une perte d'énergie. Dans le cas d'un quatre temps turbo compresseur, le problèmede la grandeur de la chambre de combustion est complexe. the 4-stroke has the drawback of having to make two revolutions of the engine to obtain an explosion, with in addition many moving parts, and therefore a loss of energy. In the case of a four-stroke turbo compressor, the problem of the size of the combustion chamber is complex.

On la souhaite petite à bas régime et très grande dans les hauts régimes, ceci oblige donc à faire un compromis. Le moteur 2temps est plutôt réservé aux petites cylindrées, car son système d'échappement le rend très gourmand et inadapté au turbo. Le moteur rotatif rencontre des problèmes qui ne sont pas compensés par les avantages.We want it small at low revs and very large at high revs, so this requires a compromise. The 2-stroke engine is rather reserved for small displacement, because its exhaust system makes it very greedy and unsuitable for turbo. The rotary engine has problems that are not outweighed by the benefits.

L'invention concerne un nouveau système pour emprisonner des gaz (air + essence) les comprimer et les faire exploser au moyen d'une étincelle, fournie par un allumage classique. le dispositif se présente sous la forme d'une roue à aubes, pleine sur sa partie centrale et d'une très faible épaisseur par rapport à son diamètre. Les dimensions peuvent etre variablesen fonction de la cylindrée désiré. La largeur et l'écartement des pales est similaire à l'alésage et à la course du moteur classique, quant au nombre de pales on peut dire qu'il correspond au nombre de cylindres.The invention relates to a new system for trapping gases (air + petrol), compressing them and detonating them by means of a spark, supplied by a conventional ignition. the device is in the form of a paddle wheel, solid on its central part and of a very small thickness compared to its diameter. The dimensions can be variable depending on the desired displacement. The width and spacing of the blades is similar to the bore and stroke of the conventional engine, as for the number of blades we can say that it corresponds to the number of cylinders.

Cette roue à aubes (1) tourne à l'intérieur d'un cylindre (7) fermé sur les deux extrémités, fermant ainsi le bloc moteur, et dont le centre serait l'axe de rotation de la roue. Entre chaque pale il y a le même écartement et chacune disposera de segments d'etanchéité qui froteront sur le diamètre intérieur du cylindre et sur les joues intérieures.This paddle wheel (1) rotates inside a cylinder (7) closed on both ends, thus closing the engine block, and whose center would be the axis of rotation of the wheel. Between each blade there is the same spacing and each will have sealing segments which will rub on the internal diameter of the cylinder and on the internal cheeks.

les schémas ci-joints montrent dans la vue suivant H Figure 1, le coté ou sont placés les échappements et les six bougies. Sur le coté F, sont placés les caissons d'admission (3) et les pistons de compression (4). Une grande encoche esL prévue sur le bloc (7) pour leur permettre de coulisser. Ils sont placés l'un contre l'autre. Sur la figure 7, on peu voir qu'ils ont une face (on l'appelera face J) qui doit venir (lorsque les deux pièces sont en position arrière) s'aligner avec le carter et permettre à la pale (2) de continuer à coulisser sans aucun acrochage. Pour mieux comprendre, on dira que dans la Figure 4, la pièce 3 est en position avant et la pièce 4 en position arrière. Dans la figure 5, les deux pièces (3 et 4) sont en position avant.the attached diagrams show in the view following H Figure 1, the side where the exhausts and the six spark plugs are placed. On side F, are placed the intake boxes (3) and the compression pistons (4). A large notch esL provided on the block (7) to allow them to slide. They are placed against each other. In figure 7, we can see that they have a face (we will call it face J) which must come (when the two parts are in the rear position) to align with the casing and allow the blade (2) to continue to slide without any hooking. To better understand, we will say that in Figure 4, part 3 is in the front position and part 4 in the rear position. In figure 5, the two parts (3 and 4) are in the front position.

Dans la Figure 6, la pièce 4 est en position avant et la pièce 3 en position arrière. Chacune de ces deux pièces, doit avoir un éléctro-aimant à double sens (avant + arrière). Pour le piston de compression (4) on peu aussi faire un montage avec un petit villebrequin, qui le ferait bouger mécaniquement.In Figure 6, part 4 is in the front position and part 3 in the rear position. Each of these two parts must have a two-way electromagnet (front + rear). For the compression piston (4) we can also make an assembly with a small crankshaft, which would make it move mechanically.

Mais je pense que le système éléctro-aimant est de nos jours bien maitrisé pour obtenir ce que l'on souhaite. Les ressorts de rappel (15) ne servent que dans le cas d'une panne, afin que les pièces 3 ou 4 restent en position arrière et ne se trouvent pas en contact avec les pales.But I think that the electromagnet system is nowadays well mastered to get what we want. The return springs (15) are only used in the event of a breakdown, so that parts 3 or 4 remain in the rear position and are not in contact with the blades.

Sur la Figure 2, on voit les boitiers d'éléctro-aimants (17) et les capteurs dont voici le tableau de déclanchement
Capteur 8 ramène le caisson (3) par l'éléctro-aimant (5) en arrière.In Figure 2, we see the electromagnet boxes (17) and the sensors of which here is the trigger table
Sensor 8 brings the box (3) back by the electromagnet (5).

Capteur 9 ramène le piston (4) par l'éléctro-aimant (6) en arrière.Sensor 9 brings the piston (4) back via the electromagnet (6).

Capteur 10 pousse le caisson (3) par ltéléctro-aimant (5) en avant.Sensor 10 pushes the box (3) forward by the electromagnet (5).

Capteur 11 pousse le piston (4) parl'éléctro-aimant (6) en avant.Sensor 11 pushes the piston (4) by the electromagnet (6) forward.

Capteur 12 étincelle bougie.Spark plug sensor 12.

La pièce (18) étant la couronne pour déclencher l'excitation des capteurs.The part (18) being the crown to trigger the excitation of the sensors.

Les figures 4, 5, 6, et 7 montrentles différents cycles du fonctionnement
FIG.4 admission par le caisson (3) échappement en même temps.Figures 4, 5, 6, and 7 show the different operating cycles
FIG. 4 admission through the exhaust box (3) at the same time.

FIG.5 le piston (4) vient de comprimer, l'explosion s'est produite, échap
pement toujours en cours.FIG. 5 the piston (4) has just compressed, the explosion has occurred, escape
still in progress.

FIG.6 Le caisson (3) vient de se retirer pour permettre à la pale (2) de
passer, un nouveau cycle d'échappement commence.FIG. 6 The box (3) has just been withdrawn to allow the blade (2) to
pass, a new exhaust cycle begins.

FIG.7 le piston de compression (4) s'est mis lui aussi en position arrière,
les gaz d'échappement restant sont évacués sous pression par la pale (2).FIG. 7 the compression piston (4) has also moved to the rear position,
the remaining exhaust gases are evacuated under pressure by the blade (2).

Ensuite le cycle se renouvelle comme sur la figure 4.Then the cycle is renewed as in figure 4.

Le bloc moteur devra comporter tout autour du piston (4) et du caisson (3) des segments d'etanchéité qui n'ont pas été dessinés, ainsi que le circuit de graissage , afin que les dessins soient plus compréhensifs.The engine block must include all around the piston (4) and the casing (3) sealing rings that have not been drawn, as well as the lubrication circuit, so that the drawings are more comprehensive.

Toutes les figures ci-jointes, ne sont que des schémas. Les figures i et 2 sont réduites de moitié par rapport aux autres. All figures attached are only diagrams. Figures i and 2 are halved compared to the others.

Les gaz d'échappement sont évacués sous pression et peuvent entraîner un turbo-compresseur pour comprimer l'air ou les gaz d'admission.The exhaust gases are vented under pressure and can drive a turbo-compressor to compress the air or intake gases.

Un boîtier électronique reçoit les données des capteurs (ou cellules) et déclenche le mouvement des électro-aimants, ce boîtier est capable d'analyser la vitesse de rotation de la roue, la pression ou la dépression à l'admission. Avec ces données, il peut retarder plus ou moins le moment de déclenchement des électro-aimants et de l'étincelle des bougies.An electronic box receives the data from the sensors (or cells) and triggers the movement of the electromagnets, this box is able to analyze the speed of rotation of the wheel, the pressure or the vacuum at the inlet. With this data, it can delay more or less the timing of the triggering of the electromagnets and the spark of the spark plugs.

Plus le retard est grand et plus la chambre de combustion est grande.The greater the delay, the larger the combustion chamber.

REVENDICATIONS 1. Moteur à explosions caractérisé par le fait, qu'il sagit d'un rotor à pales (1) tournant dans un cylindre (7) de grand diamètre et de faible épaisseur. 1. Explosion engine characterized in that it is a bladed rotor (1) rotating in a cylinder (7) of large diameter and thin. 2. revendication 1. Grace à des caissons d'admission (3) et à des pistons de compression (4), actionnés par des éléctro-aimants (5 et 6) on peu obtenir autant d'explosions simultanées que le rotor contient de pales, répétés autant de fois que le rotor contient de pales pour chaque tour. 2. Claim 1. Thanks to the intake chambers (3) and to the compression pistons (4), actuated by electromagnets (5 and 6), we can obtain as many simultaneous explosions as the rotor contains blades. , repeated as many times as the rotor contains blades for each revolution. Exemple : si on prend un rotor à six pales (2) comme celui du dessin cijoint, on aura six fois six explosions. Soit au total trente six explosions au tour. Si il avait douze pales, on aurait cent quarante quatre explosions pour un tour de moteur.Example: if we take a rotor with six blades (2) like the one in the accompanying drawing, we will have six times six explosions. That is a total of thirty six explosions per turn. If he had twelve blades, we would have one hundred and forty-four explosions for one revolution of the engine. 3. revendication 2. Le système d'échappement de ce moteur étant sous pression, il est donc possible d'entrainer un turbo compresseur.le particularité est, que l'on peu choisir le volume de la chambre de combustion (20). 3. Claim 2. The exhaust system of this engine being under pressure, it is therefore possible to drive a turbo compressor. The particularity is that we can choose the volume of the combustion chamber (20). Eh faisant un boitier éléctronique avec une courbe de retard, sur les capteurs qui commandent le piston de compression et l'étincelle de la bougie, on obtient une chambre qui peut grossir à volonté en fonction du régime moteur de la dépression d'admission ou de la pression de l'admission. By making an electronic box with a delay curve, on the sensors which control the compression piston and the spark of the spark plug, we obtain a chamber which can grow at will depending on the engine speed of the intake depression or intake pressure.
