Abstract

The engine combines the effects of a traditional turbo-compressor and a double-action piston on a single axle. The power produced by the double action piston is transmitted through a connecting rod to a toothed crown wheel which transmits its motion to the cylinder compressor and turbine. The engine combines on a single axle the effects of a traditional turbo-compressor (1, 2) and a double-action piston (7), with the cylinder (3) in which the explosions take place connected to the turbo compressor assembly and turning at the same speed as it, with the end of the cylinder fitted with a drive pinion (6). The outside of the cylinder has exhaust gas ports (4) and a turbine (5) for recuperating the exhaust gas energy, while the piston inside the cylinder forms two combustion chambers, fed alternately through inlet ports. The power produced by the piston is transmitted through a connecting rod (9) to a toothed crown wheel which transmits its motion to the cylinder, compressor and turbine.

Description

La présente invention concerne un dispositif de moteur thermique, combinant sur un même axe les effets d'un TÙrt)o-conrrresseur classique avec un piston à double action. The present invention relates to a thermal engine device, combining on the same axis the effects of a conventional TÙrt) o-conrrressor with a double action piston.

Ce dispositifpeut-etre utilisé dans tous les systèmes de propulsion de véhicules (aviation,automobiles,marine,etc.)
Originalité de l'invention:
Le cylindre,solidaire de la turbine et du compresseur,tourne avec ceux-ci,l'entrainement s'effectuant par l'intermediaire d'une couronne,elle même actionnée par les mouvements alternatifs d'un arbre moteur supportant le piston.This device can be used in all vehicle propulsion systems (aviation, automobiles, marine, etc.)
Originality of the invention:
The cylinder, integral with the turbine and the compressor, rotates with these, the drive being effected by means of a crown, itself actuated by the reciprocating movements of a motor shaft supporting the piston.

Le piston est fixé par son axe,sur cet arbre moteur,et se déplace donc en même temps que celui-ci.The piston is fixed by its axis, on this motor shaft, and therefore moves at the same time as the latter.

Ce dispositif d'arbre moteur axial,pemet de placer 1 ou plusieurs pistons en série, avec des chambres d'explosion également en sèrie à l'intérieur d'un cylindre commun
Le piston est à double effet, son déplacement déterminant 2 chambres d'explosion dans le cylindre,et donc 2 explosions par cycle.This axial motor shaft device allows 1 or more pistons to be placed in series, with explosion chambers also in series inside a common cylinder
The piston has a double effect, its displacement determining 2 explosion chambers in the cylinder, and therefore 2 explosions per cycle.

L'admission s'effectue par des lumières percées dans l'arbre moteur creux ,et l'échappement par des lu fières périphériques dans le cylindre.The intake takes place through lights pierced in the hollow motor shaft, and the exhaust through proud peripheral lights in the cylinder.

Les organes de,distribution sont extrèmement simplifiés:
Pas de culbuteurs,pas de soupapes,pas d'arbre à cames.The distribution organs are extremely simplified:
No rocker arms, no valves, no camshaft.

Les schémas en annexe illustrent l'invention:
PL 1/3-Coupes du moteur . PL 2/3-Détail des diffents éléments. PL 3/3 - Variantes
En référence à ces schémas, le dispositif est composé: 1/ D'une partie tournante sur son axe comportant (PL lJ3-Fig 1) -Un corps basse pression (1),2 étages compresseur haute pression (2),Un cylindre (3) solidaire des éléments précédents comportant sur sa périphérie des lumières d'échappement(4),ainsi qu'une turbine à 1 ou plusieurs corps permettant la récupération de l'énergie des gaz d'échappement (5).The attached diagrams illustrate the invention:

With reference to these diagrams, the device is made up of: 1 / A rotating part on its axis comprising (PL lJ3-Fig 1) -A low pressure body (1), 2 high pressure compressor stages (2), A cylinder ( 3) integral with the preceding elements comprising on its periphery exhaust lights (4), as well as a turbine with 1 or more bodies allowing the recovery of the energy of the exhaust gases (5).

La tête de ce cylindre comporte un pignon d'entrainement (6).The head of this cylinder has a drive pinion (6).

-A l'intérieur de ce cylindre, un piston (7) solidaire d'un arbre moteur axial (8),se déplace alternativement en délimitant 2 chambres d'explosion (A) et (B). Le mouvement alternatif de ce piston et de son arbre, par l'intermédiaire d'une bielle (9),engendrela rotation d'une couronne (10-Fig 2) entrainant le pignon (6) du cylindre et donc tout l'ensemble turbine/compresseur.-Inside this cylinder, a piston (7) secured to an axial motor shaft (8), moves alternately, delimiting 2 explosion chambers (A) and (B). The reciprocating movement of this piston and its shaft, via a connecting rod (9), generates the rotation of a crown (10-Fig 2) driving the pinion (6) of the cylinder and therefore the whole turbine assembly /compressor.

-L'arbre moteur creux (8) sur une partie de sa longueur permet alternativement par les lumières (11) et (12), l'admission du mélange air/carburant (13) dans les chambres A et
B,où des bougies (14) et (15) ou tout autre système assurent l'allumage.-The hollow motor shaft (8) over part of its length allows alternately through the lights (11) and (12), the admission of the air / fuel mixture (13) into the chambers A and
B, where spark plugs (14) and (15) or any other system ensure ignition.

En inversant la positiondu carter de trsnsmission et du cylindre, celui-ci se trouvant en bout d'arbre,ce dernier est creux sur toute sa longueur (PL3/3-Figll). By reversing the position of the transmission housing and the cylinder, the latter being at the end of the shaft, the latter is hollow over its entire length (PL3 / 3-Figll).

La lumière d'échappement(4) est ouverte et simultanément la lumière d'admission(12) fait pénétrer les gaz dans la chambre(B).The exhaust light (4) is open and at the same time the intake light (12) causes the gases to enter the chamber (B).

FONCTIONNEMENT.OPERATION.

L'air frais est comprimé dans la partie basse pression (1) et haute pression(2) où il se mélange au carburant (13)
Ce mélange est propulsé dans l'arbre creux (8) qui supporte le piston(7). The fresh air is compressed in the low pressure (1) and high pressure (2) part where it mixes with the fuel (13)
This mixture is propelled into the hollow shaft (8) which supports the piston (7).

Suivant la position de ce dernier,des lumières d'admission (11) et (12) laissent pénétrer, alternativement le mélange dans les chambres d'explosion A et B.Depending on the position of the latter, intake lights (11) and (12) allow the mixture to enter, alternately into the explosion chambers A and B.

Les lumières d'échappement (4) situées en périphérie du cylindre (3), sont communes aux 2 chambres d'éxplosion. The exhaust lights (4) located on the periphery of the cylinder (3) are common to the 2 explosion chambers.

Ce piston à double effet,présente donc l'originalité de réaliser 2 explosions par cycle.This double-acting piston therefore has the originality of producing 2 explosions per cycle.

En effet, pendant que l'explosion se produit dans la chambre (A),l'échappement et l'admission des gaz,se font dans la chambre (B).In fact, while the explosion occurs in the chamber (A), the exhaust and the admission of gases take place in the chamber (B).

Le retour du piston dans celle-ci déclenche donc le même cycle que précédemment.The return of the piston therein therefore triggers the same cycle as before.

Par l'intermédiaire de l'arbre (8) solidaire du piston (7) la force motrice produite est donc transmise 8 la couronne (10) par la bielle (9),et,par l'eninement du pignon (6), å l'ensemble cylindre,turbine;compresseur. By means of the shaft (8) integral with the piston (7), the driving force produced is therefore transmitted 8 to the crown (10) by the connecting rod (9), and, by the insertion of the pinion (6), å the cylinder, turbine and compressor assembly.

Pour un meilleur équilibrage des forces tnnises par l'arbre sur la couronne,on double celle-ci (10 a).For better balancing of the forces generated by the shaft on the crown, it is doubled (10 a).

La deuxième (10 b),tournant en sens imerse,on a donc une meilleure répartition des forces exercées sur les 2 bielles (9al9b). The second (10b), turning in an imerse direction, there is therefore a better distribution of the forces exerted on the 2 connecting rods (9al9b).

Suivant le rapport d'engrenage choisi,on obtient une vitesse de rotation du pignon(6), x fois plus rapide que celle des couronnes (10a/10b)-Fi & 13.Depending on the gear ratio chosen, a speed of rotation of the pinion (6) is obtained, x times faster than that of the crowns (10a / 10b) -Fi & 13.
