Abstract

The innovation relates to an engine with a rotary piston. It is characterised by a case (1) having the shape of two semicircles joined together so that they are slightly separated, and closed by two caps which are traversed at their centre by a shaft (3) on which is fixed a rotary piston (2) equipped with four articulated and guided arms (4.5.6.7.) which create chambers (10.12.13.14.) with the internal casing of the case. The variation in the volume of these chambers brings together the conditions necessary for the operation of a compression-ignition or spark-ignition internal combustion engine.

Description

Depuis plusieurs années, de nombreuses études ont été effectuées sur les moteurs à pistons rotatifs. Seuls quelques moteurs de ce genre ont été commercialisés et à ce jour, ils n'arrivent pas à concurencer les moteurs à pistons alternatifs. For several years, numerous studies have been carried out on rotary piston engines. Only a few such engines have been marketed and to date they cannot compete with reciprocating piston engines.

La présente invention, par sa simplicité, ne devant pas poser de problèmes techniques -insurmontables, devrait permettre la construction d'un moteur à piston rotatif compétitif. The present invention, by its simplicity, should not pose -insurmountable technical problems, should allow the construction of a competitive rotary piston engine.

Le principe de fonctionnement est le suivant:
Un axe traverse en son centre le carter constituant l'enveloppe du moteur, fermé par deux chapeaux. Ce carter a la forme de deux de deux demi-cercles reliés de façon légèrement écartés. Sur cet axe est fixé un piston rotatif muni de quatre bras usinés de telle façon que les sommets de ces bras soient les arcs d'un cercle imaginaire ayant pour centre le milieu de l'axe et que ces arcs, lors de leur rotation, affleurent les parties aplaties du carter. Sur une des faces de chaque bras, un piston oscillant est articulé et, l'autre face est usinée de façon à permettre l'oscillation de la tête de piston. Les chapeaux de carter sont rainurés à une distance constante des parois du carter et, la partie intérieure des têtes de piston est munie d'ergots sur lesquels sont fixées des pièces qui coulisseront dans ces rainures.L'angle extérieur des têtes de piston est donc toujours en contact avec la paroi du carter.The operating principle is as follows:
An axis crosses in its center the casing constituting the envelope of the engine, closed by two caps. This housing has the form of two of two semicircles connected in a slightly spaced manner. On this axis is fixed a rotary piston provided with four arms machined in such a way that the vertices of these arms are the arcs of an imaginary circle having for center the center of the axis and that these arcs, during their rotation, are flush the flattened parts of the housing. On one face of each arm, an oscillating piston is articulated and, the other face is machined so as to allow the oscillation of the piston head. The crankcases are grooved at a constant distance from the walls of the crankcase and, the interior part of the piston heads is provided with lugs on which are fixed parts which will slide in these grooves. The outside angle of the piston heads is therefore always in contact with the housing wall.

La figure 1 représente, en coupe, une vue intérieure du moteur
La figure 2 représente la partie intérieure du chapeau de carter
La fifure 3 représente une vue en perspective d'un piston oscillant.Figure 1 shows, in section, an interior view of the engine
Figure 2 shows the inner part of the crankcase cap
The fifure 3 represents a perspective view of an oscillating piston.

A l'intérieur du carter I, le piston rotatif 2, fixé sur l'axe 3, tourne dans le sens de la flèche F. Lors de cette rotation selon la figure 1, le piston 4, guidé par la rainure 8 des chapeaux et la pièce baladeuse de l'ergot 9, crée une chambre 10 entre les pistons 4 et 7, en aspirant du mélange en Il. En même temps, la chambre 12, créé précédemment entre les pistons 4 et 5, commence à se compresser. La chambre 13 formée par les pistons 5 et 6 est complètement compressée et c'est ltexplosion-détente; la chambre 14 formée par les pistons 6 et 7 commence l'évacuation des gaz brûlés en 15. Inside the housing I, the rotary piston 2, fixed on the axis 3, rotates in the direction of the arrow F. During this rotation according to FIG. 1, the piston 4, guided by the groove 8 of the caps and the wandering part of the lug 9, creates a chamber 10 between the pistons 4 and 7, by sucking mixture in It. At the same time, the chamber 12, previously created between the pistons 4 and 5, begins to compress. The chamber 13 formed by the pistons 5 and 6 is completely compressed and it is explosion-detent; the chamber 14 formed by the pistons 6 and 7 begins the evacuation of the burnt gases at 15.

Les quatre temps du moteur à explosion sont donc simultanés. The four times of the internal combustion engine are therefore simultaneous.

La face du piston exposée à l'explosion sera légèrement creusée en son centre pour recevoir une poussée perpendiculaire à cette face (20). Afin de supprimer les compressions dans les logements des pistons oscillants, les chapeaux seront percés de façon circulaire 15 (fig.2), à la base des logements de ces pistons. Pour assurer l'étanchéité des chambres, les pistons seront munis d'au moins un joint 16 sur les faces latérales, allant de l'axe du piston oscillant, jusqu'à la tête côté intérieur, et d'un joint 17 passant par l'angle extérieur de la tête de piston et rejoignant le joint 16. Les bras du piston rotatif auront également au moins un joint d'étanchéité 18 entre les chapeaux et des garnitures d'épousement 19 entre les têtes de piston. The face of the piston exposed to the explosion will be slightly hollowed out in its center to receive a thrust perpendicular to this face (20). In order to eliminate the compressions in the housings of the oscillating pistons, the caps will be drilled in a circular manner 15 (fig. 2), at the base of the housings of these pistons. To ensure the tightness of the chambers, the pistons will be provided with at least one seal 16 on the lateral faces, going from the axis of the oscillating piston, to the head on the interior side, and with a seal 17 passing through the external angle of the piston head and joining the seal 16. The arms of the rotary piston will also have at least one seal 18 between the caps and marrying fittings 19 between the piston heads.

Selon la description de fonctionnement de ce moteur, on peut, en fonction de l'écartement donné aux deux demi-cercles du carter, faire varier les compressions afin d'obtenir un moteur à explosion ou un moteur fonctionnant comme un moteur diésel.  According to the operating description of this engine, it is possible, depending on the spacing given to the two semicircles of the casing, to vary the compressions in order to obtain an internal combustion engine or an engine operating as a diesel engine.
