Abstract

Heat engine with two rotary pistons and oscillating pistons of the four-stroke type in which the first two strokes, admission and compression, take place in a first chamber, explosion and exhaust in a second, the explosion taking place in a specific chamber common to the first two characterising the engine.

Description

Le moteur présente ici est du type thermique à pistons rotatifs et combustion interne. Il est constitue de deux pistons (13 a) et (13 b), d'un axe de rotation (3) qui est l'arbre moteur. The engine present here is of the rotary piston and internal combustion thermal type. It consists of two pistons (13 a) and (13 b), an axis of rotation (3) which is the drive shaft.

Le moteur est composé sur la figure I par un axe de rotation (3) creux portant deux pistons rotatifs s le piston admission (13 a) et le piston échappement (13 b). Chaque piston tourne dans une chambre : chambre d'admission (5) et chambre d'ahhappement (4) séparées de façon étanche par une paroi de séparation (21). Les deun chambres sont en communication par l'intermédiaire de la chambre d'explosion (23) composée de deux saacr chambres, ne dans la chambre d'explosion (23 a), l'autre dans la cham- bre d'échappement (23 b).Ces deux sous-ehambres sont réunies par un canal (24) oui traverse la paroi de séparation (21) au niveau du carter cylindre où sont creusées les deux sous-chambres. The engine is composed in Figure I by a hollow axis of rotation (3) carrying two rotary pistons s the intake piston (13 a) and the exhaust piston (13 b). Each piston rotates in a chamber: inlet chamber (5) and exhaust chamber (4) separated in a sealed manner by a partition wall (21). The two chambers are in communication via the explosion chamber (23) composed of two saacr chambers, one in the explosion chamber (23 a), the other in the exhaust chamber (23 b). These two sub-chambers are joined by a channel (24) yes crosses the partition wall (21) at the level of the cylinder block where the two sub-chambers are dug.

Sur la iigure n II réprésentant mie coupe transversale de la chambre d'admission (5), le piston d'admission (13 a) est porteur de deux pistons oscillants (10) articulés par un axe (20) à la partie périphérique du piston admission (13 a) et dont l'autre extrémité se déplace de façon oscillante dans nn évidement du piston rotatif (13 a) autour de l'axe (20), l'extrémité oscillante est guidée dans son mouvement par deux tétens coulissant dans deux gorges excentriques (16 a et (16 b) creusées dans la paroi de séparation (21) et dans la face latérale interne (22).  On iigure n II representing a cross section of the intake chamber (5), the intake piston (13 a) carries two oscillating pistons (10) articulated by an axis (20) at the peripheral part of the piston inlet (13 a) and the other end of which moves in an oscillating manner in a recess of the rotary piston (13 a) around the axis (20), the oscillating end is guided in its movement by two lugs sliding in two eccentric grooves (16 a and (16 b) hollowed out in the partition wall (21) and in the internal lateral face (22).

L'admission dn mélange air et combustible se fait par la pipe d'admission (6) creuse dans le carter cylindre (12).The admission of air and fuel mixture is through the hollow intake pipe (6) in the cylinder housing (12).

Sur la figure III représentant une coupe transversale de la chambre d'échappement, c'est l'image de la chambre d'admission après rotation de 180e par rapport à son axe. In Figure III showing a cross section of the exhaust chamber, this is the image of the intake chamber after rotation of 180th relative to its axis.

Le pisten (13) est porteur de segment dtétanchéité (15) frottant sur la paroi interne circulaire du carter cylindre et d'une pièce solidaire du piston (1) sur chacune de ses faces, possédant un évidement (14) pour le passage du téton (8), des orifices de maintien des segments d'étanchéité (19)
Le carter cylindre (12) possède des canaux de circulation d'eau (17) pour le refroidissement de l'ensembleo
La lubrification se fait par l'intermédiaire de l'axe de rotation (3) et par les canaux de lubrification (11) creusés dans le piston.The piston (13) carries a sealing segment (15) rubbing against the circular internal wall of the cylinder block and of a part integral with the piston (1) on each of its faces, having a recess (14) for the passage of the stud. (8), orifices for holding the sealing segments (19)
The cylinder housing (12) has water circulation channels (17) for cooling the assembly.
Lubrication takes place via the axis of rotation (3) and through the lubrication channels (11) hollowed out in the piston.

Le calage des pistons rotatifs (13) est détermine de sorte que le piston oscillant (10) du piston échappement (13 b) se trouve en face de la sous-chambre d'explosion de la chambre d'échappement (4) au moment où a lieu l'explosion, tandis que le piston oscillant (10) du piston admission (13 a) vient fermer la sous-chambre explosion (23 a) de la chambre d'admission. (5)
Au cours d'un cycle oomplet, le piston oscillant (10) du piston admission (5) passe devant la pipe d'admission (6) et se décolle de la périphérie vers le centre sous l'effet de la gorge excentrée (16).The setting of the rotary pistons (13) is determined so that the oscillating piston (10) of the exhaust piston (13 b) is opposite the explosion sub-chamber of the exhaust chamber (4) at the moment when the explosion takes place, while the oscillating piston (10) of the intake piston (13 a) closes the explosion sub-chamber (23 a) of the intake chamber. (5)
During a complete cycle, the oscillating piston (10) of the intake piston (5) passes in front of the intake pipe (6) and comes off from the periphery towards the center under the effect of the eccentric groove (16) .

 ce moment, se crée un espaoe vide qui attire par dépression le comburant. At this moment, an empty space is created which attracts the oxidizer by depression.

La rotation du piston admission (5) se poursuit et le piston oscil- lant (10) se retrouve devant la sous-chambre d'admission (23 a) de la chambre d'explosione Celui-ci recolle à la périphérie par l'effet de la gorge et force ainsi le comburant à passer dans cette sous-chambre (23 a) et traverse le canal (24) de communioation,
Au même instant, le piston oscillant (10) du piston échappement (4) arrive par rotation, en face de la sous-chambre d'échappement (23 b) de la chambre d'explosion (23j.The rotation of the intake piston (5) continues and the oscillating piston (10) is found in front of the intake sub-chamber (23 a) of the explosion chamber. This sticks to the periphery by the effect. throat and thus forces the oxidant to pass into this sub-chamber (23 a) and crosses the communication channel (24),
At the same instant, the oscillating piston (10) of the exhaust piston (4) arrives by rotation, opposite the exhaust sub-chamber (23 b) of the explosion chamber (23j.

L'allumage se produit et l'explosion entratne alors la répulsion de ce piston oscillant (10) le décollant de la périphérie vers le centre, ce qui induit un mouvement rotatoire qui est le mouvement moteur
La rotation entratne 1' éloignement du piston oscillant (10). Ignition occurs and the explosion then causes the repulsion of this oscillating piston (10) taking off from the periphery towards the center, which induces a rotary movement which is the motor movement.
The rotation drives away the oscillating piston (10).

Son mouvement guidé par la gorge (16) permet de recevoir les gaz brtlés après l'explosion.Its movement guided by the groove (16) allows to receive the burnt gases after the explosion.

Puis le piston oscillant (10) passe devant la pipe d'échappement et se rapproche de la périphérie sous l'effet de la gorge. Then the oscillating piston (10) passes in front of the exhaust pipe and approaches the periphery under the effect of the groove.

Les gaz brayés sont rejetés à l'extérieur de la chambre d'échappement
Au même moment, se produit un nouveau cycle admission explosion puis échappement. Le mouvement s'entretient par l'intermédiaire de l'allumage. Brayed gases are discharged outside the exhaust chamber
At the same time, a new explosion intake and exhaust intake cycle takes place. The movement is maintained by means of the ignition.
