Abstract
Description
La présente invention concerne un moteur thermique (à explosion ou diesel) à culasses et pistons mobiles dont le mouvement est circu- laire et à sens unique autour d'ion seul axe : oelui de l'arbre moteur0
Les moteurs thermiques actuels fonctionnent, pour la plupart, par transformation du mouvement rectiligne en mouvement circulaire s quel- ques uns sont dita rotatifs mais font appel, soit à des mouvements dé saxes, soit à des cames, soit à des pistons annexes à mouvement recti- ligne, aucun n'est exclusivement à mouvement circulaire à sens unique autour d'un seul axe.The present invention relates to a heat engine (internal combustion or diesel) with movable cylinder heads and pistons, the movement of which is circular and one-way around a single axis ion: that of the engine shaft
Most of the current heat engines operate by transforming the rectilinear movement into a circular movement, some of which are said to be rotary, but use either axis movements, cams or annexed pistons with recti movement. - line, none is exclusively circular movement in one direction around a single axis.
Les organes moteurs selon l'invention sont disposés en couronne autour d'un meme axe : celui de l'arbre moteur Ils sont animés due mouvement circulaire à sens unique autour de eet axe
Les éléments mobiles (culasses et pistons) se meuvent dans un es pace en forme de couronne creuse où les quatre temps (admission, com- pression, détente, échappement) ont lieux
Une culasse est toujours lie å un piston formant ainsi un en semble culasse-piston, la culasse orientée dans le sens de rotation du moteur et le piston orienté en sens inverse de rotation du moteur; ainsi la culasse d'un ensemble oulassewpiston agit sur le piston deun autre ensemble culasse-piston0
Nous appelons culasse et piston solidaires de l'arbre moteur "ou r lasse solidaire" et "piston solidaire", et culasse et piston tournant librement autour de l'arbre moteur "culasse libre" et "piston libre".The drive members according to the invention are arranged in a crown around the same axis: that of the drive shaft. They are driven by circular movement in one direction around this axis.
The mobile elements (cylinder heads and pistons) move in a space in the form of a hollow crown where the four stages (intake, compression, expansion, exhaust) take place
A cylinder head is always connected to a piston thus forming a similar cylinder head-piston, the cylinder head oriented in the direction of rotation of the engine and the piston oriented in the opposite direction of rotation of the engine; thus the cylinder head of one piston cylinder assembly acts on the piston of another cylinder piston assembly
We call cylinder head and piston integral with the engine shaft "or r lasse integral" and "piston integral", and cylinder head and piston rotating freely around the engine shaft "free cylinder head" and "free piston".
Ce nouveau type de moteur doit comporter un (ou plusieurs) ensemble culasse-piston solidaire de l'arbre moteur (ensemble solidaire) correspondant à un (ou plusieurs) ensemble -culasse-piston tournant librement autour de l'arbre moteur (ensemble libre). This new type of engine must include one (or more) cylinder head-piston assembly integral with the engine shaft (integral assembly) corresponding to one (or more) cylinder head-piston assembly freely rotating around the engine shaft (free assembly) .
La jonction avec les pièces en mouvement des différents conduits permettant l'admission et l'échappement a son étanchéité assurée psr les procédés existants. The junction with the moving parts of the various conduits allowing the admission and the exhaust has its tightness ensured by existing processes.
L'étanchéité des ensembles en mouvement est assurée par des segments. Sealing of moving assemblies is ensured by segments.
La lubrification et le refroidissement sont traditionnels. Lubrication and cooling are traditional.
Pour décrire le fonctionnement, prenons pour exemple un moteur à explosion comportant 1
- deux ensembles culasse-piston (S1 et S2) solidaires de l'arbre moteur et disposés symétriquement par rapport à son axe 9
- deux ensembles culasse-piston (L1 et L2) libres et disposés symétriquement par rapport à l'axe du moteur
Les figures 1 et 2 illustrent par schémas les différentes phases de fonctionnement, (rotation en sens inverse des aiguilles d'une montre) î
- figure 1, simultanément s
explosion entre culasse G de 31 et piston P de Ll,
détente entre culasse C de L1 et piston P de S2,
admission entre culasse o de 32 et piston P de L22
admission entre culasse C de L2 et piston P de S19
- figure 2, simultanément s
explosion entre culasse C de L2 et piston P de S1,
échappement entre culasse C de 31 et piston P de L1,
admission entre culasse C de L1 et piston P de S2,
compression entre culasse C de 32 et piston P de L2.To describe the operation, take for example an internal combustion engine comprising 1
- two cylinder head-piston assemblies (S1 and S2) integral with the motor shaft and arranged symmetrically with respect to its axis 9
- two free cylinder head-piston assemblies (L1 and L2) arranged symmetrically with respect to the axis of the engine
Figures 1 and 2 illustrate by diagrams the different operating phases, (counterclockwise rotation) î
- figure 1, simultaneously s
explosion between cylinder head G of 31 and piston P of Ll,
trigger between cylinder head C of L1 and piston P of S2,
intake between cylinder head o of 32 and piston P of L22
intake between cylinder head C of L2 and piston P of S19
- figure 2, simultaneously s
explosion between cylinder head C of L2 and piston P of S1,
exhaust between cylinder head C of 31 and piston P of L1,
intake between cylinder head C of L1 and piston P of S2,
compression between cylinder head C of 32 and piston P of L2.
Les ensembles S1 et S2 étant solidaires de l'arbre moteur et de son volant d'inertie, les ensembles L1 et L2 étant libres par rapport à l'arbre moteur, le mouvement des ensembles 31 et 52 est régulier et le mouvement des ensembles Ll et L2 irrégulier. Ainsi la "course" est définie par les écartements et rapprochements successifs entre S1 52 et L1 L2. The sets S1 and S2 being integral with the drive shaft and its flywheel, the sets L1 and L2 being free relative to the drive shaft, the movement of the sets 31 and 52 is regular and the movement of the sets Ll and L2 irregular. Thus the "race" is defined by the successive spacings and closings between S1 52 and L1 L2.
Le frein (Qa) se met en service lors de l'arrivée à son niveau de l'ensemble L qui le libérera au moment voulu g même processus pour le frein (Qb). The brake (Qa) is put into service when the set L arrives at its level which will release it at the desired time g same process for the brake (Qb).
La figure 3 est une vue écorchée montrant une des différentes possibilités d'assemblage des ensembles mobiles du moteur selon l'invention. FIG. 3 is a cutaway view showing one of the different possibilities for assembling the mobile assemblies of the engine according to the invention.
Bes utilisations de oette invention sont toutes celles qui con- oernent les moteurs à explosion ou diesel. The uses of this invention are all those which relate to internal combustion or diesel engines.
