--- de deux flasques latéraux 12 (un seul étant repré- senté)oü sont fixées deux cames par flasque 4a-4b,sont accolés de part et d'autre du dit stator. two lateral flanges 12 (only one being shown) where are fixed two cams per flange 4a-4b, are placed side by side of said stator.
Suite à une description succinte de l'ensemble des pièces qui constitue le dit moteur,le rôle et le fonctionnement de chacune d'elles sont définis plus précisément: -- Le stator 1 du dit moteur possède une forme trochoidale à deux lobes qui est composé d'un alésage et de deux figu res géométriques simples diamétralement opposées appelées"croissant". Following a brief description of all the parts that constitute the said engine, the role and operation of each of them are defined more precisely: - The stator 1 of said engine has a trochoidal shape with two lobes which is composed a bore and two diametrically opposed single geometric figures called "crescent".
La figure 3 montre le tracé de la forme géométrique du stator: On trace sur droite xy,deux cercles égaux et tangents;le point tangence est O;les rayons de ces deux cercles sont et BO; on trace ensuite la diagonale du cercle de rayon BO,elle coupe le cercle Cet D;1'ypothénuse OC du triangle rectangle isocèle OBC est le rayon du cercle qui. coupe en E et F le cercle de rayon AO.On obtient ainsi deux figures géométriques simples et égales S et S' appelées"croissant". Figure 3 shows the outline of the geometrical shape of the stator: One draws on xy line, two circles equal and tangent, the tangency point is O, the radii of these two circles are and BO; then draw the diagonal of the circle of radius BO, it intersects the circle This D, the hypothenuse OC of the isosceles right triangle OBC is the radius of the circle which. cut in E and F the circle radius AO.On thus obtain two simple geometric figures and equal S and S 'called "croissant".
--- Le rotor 2 du dit moteur possède une forme cylin drique dont le diamètre est très légèrement inférieur au grand alésage du stator.Muni uniquement de quatre fentes équidistantes,quatre pa lettes coulissent à l'intérieur des dites fentes. --- The rotor 2 of said engine has a cylindrical shape whose diameter is very slightly less than the large bore of the stator.Muni only four equidistant slots, four parcels slide inside said slots.
La rotation du rotor et le coulissement des palettes déterminent quatre secteurs qui permettent d'obtenir deux volumes maximaux et deux volumes minimaux.(fig.l) Un premier volume maximal défini par l'arc de cercle DJC permet admission du mélange carburant-comburant;un premier volume minimal défini par l'arc de cercle CKF permet la compression du mélange;un deuxième volume maximal défini par l'arc de cercle FIE permet la détente des gazs;un deuxième volume minimal défini par l'arc de cercle permet l'échappement des gais brûlés. The rotation of the rotor and the sliding of the pallets determine four sectors which make it possible to obtain two maximum volumes and two minimum volumes (fig.l) A first maximum volume defined by the circular arc DJC allows admission of the fuel-oxidant mixture; a first minimum volume defined by the circular arc CKF allows the compression of the mixture, a second maximum volume defined by the circular arc FIE allows the relaxation of the gases, a second minimum volume defined by the arc of a circle allows the escape of burned males.
Il en résulte que le rapport entre le volume maximal DJC et le volume minimal CKF donne un taux de compression très éle ce qui per mettra de déterminer le volume de la chambre de combustion suivant les cycles de fonctionnement,Essence ou Diesel,en creusant sur la péri phérie du rotor des cavités plus ou moins importantes à des emplace ments bien précis. As a result, the ratio between the maximum volume DJC and the minimum volume CKF gives a very high compression ratio which will make it possible to determine the volume of the combustion chamber according to the operating cycles, petrol or diesel, while digging on the Periphery of the rotor cavities more or less important to specific locations.
La position des chambres de combustion 5e-5f-5g-5h creusées sur la périphérie du dit rotor intervient sur le couple moteur qui varie en fonction de la longueur du bras de levier OH comprise entre le centre 0 du rotor et la projection du milieu Z de la chambre de com- bustion sur le bras de levier en H.(fig.4) ---- Les deux flasques latéraux 12 sont accolés de part et d'autre du stator l,dont les axes h du rotor 2 s'appuient sur les paliers 6a des dits flasques.(fig.1-fig.2) ---- Les deux cames 4a-4b,fixées ou usinées dans la masse de chaque flasque,maintiennerit sans jeu les palettes au contact de la paroi interne du stator lors de la rotation du rotor. --- Deux bossages 8 situés de. chaque côté du rotor et concentriques au grand alésage du stator maintiennent également les palettes au contact de 1a paroi. interne du stator. The position of the combustion chambers 5e-5f-5g-5h dug on the periphery of said rotor acts on the engine torque which varies as a function of the length of the lever arm OH between the center 0 of the rotor and the projection of the medium Z the combustion chamber on the lever arm H. (fig.4) ---- The two side flanges 12 are contiguous on either side of the stator l, whose axes h of the rotor 2 s' are supported on the bearings 6a of said flanges (fig.1-fig.2) ---- The two cams 4a-4b, fixed or machined in the mass of each flange, hold without play the pallets in contact with the inner wall of the stator during rotation of the rotor. --- Two bosses 8 located from. each side of the rotor and concentric with the large bore of the stator also maintain the pallets in contact with the wall. internal stator.
La figure 4 montre le mouvement des palettes 3a et 3d alors que le rotor a effectué une rotation d'un huitième de tour par rapport à la figure 1. -- Les palettes effectuent un mouvement alternatif lorsqu'elles parcourent les secteurs décrits par les deux lobes DJC et FIE.Elles restent immobiles dans leurs fentes lorsqu'elles parcourent les secteurs-décrits par le grand alésage du stator CKF et L'exemple de la figure 4 montre bien le mouvement des dites pa- lettes:la palette 3c se déplace sur une portion de secteur appartenant à un des lobes du point J au point C en pénétrant progressivement dans sa fente.Pendant ce temps la palette 3d s'est déplacé sur portion appartenant au grand alésage du point K au point F en restant immobile dans sa fente. FIG. 4 shows the movement of the pallets 3a and 3d while the rotor has rotated one-eighth of a turn relative to FIG. 1. - The pallets reciprocate as they travel through the sectors described by the two. DJC and FIE lobes. They remain motionless in their slots as they traverse the sectors-described by the large bore of the stator CKF and the example of FIG. 4 clearly shows the movement of said pallets: the pallet 3c moves on a portion of the sector belonging to one of the lobes of the point J to the point C by progressively penetrating into its slot. During this time the pallet 3d has moved on portion belonging to the large bore of the point K at the point F while remaining motionless in its slot .
Les extrémités des palettes 3a-3b-3c-3d(fig.1-fig.2)possédent une forme bien particulière afin de réduire les frottements tout en assu rant une étanchéité optimale avec la paroi interne du stator: ---- l'extrémité <B>13</B> qui coopère avec la paroi interne du stator possède la forme d'un trapèze isocèle surmonté d'un triangle isocèle --- l'extrémité 14 qui épouse le profil de la came pos sède forme analogue uniquement en chaque bout et sur largeur correspondante à celle de la dite came. --- la partie centrale<B>15</B> de la dite palette qui n'agit pas les cames est de forme rectangulaire. The ends of the pallets 3a-3b-3c-3d (fig.1-fig.2) have a very particular shape in order to reduce the friction while ensuring an optimal seal with the internal wall of the stator: end <B> 13 </ B> which cooperates with the inner wall of the stator has the shape of an isosceles trapezium surmounted by an isosceles triangle --- the end 14 which marries the profile of the cam poses similar form only at each end and on a width corresponding to that of said cam. --- The central part <B> 15 </ B> of the said pallet which does not act on the cams is of rectangular shape.
La rotation du rotor n'est possible que si: -- deux évidements 7 situés de chaque côté dit rotor sont usinés pour loger les deux cames 4a-4b fixées sur les deux flasques 12. Rotation of the rotor is only possible if: two recesses 7 located on each side of said rotor are machined to accommodate the two cams 4a-4b fixed on the two flanges 12.
La figure 2 montre la façon d'assembler le dit moteur: --- le rotor 2 s'applique contre le flasque 12. FIG. 2 shows how to assemble said motor: the rotor 2 is applied against the flange 12.
--- les deux cames 4a-4b se logent dans les évidements 7 du dit rotor. ---- les palettes 3a-3c s'appliquent contre le flasque 12,e' se logent dans les fentes du rotor. -- les extrémités 14 des dites palettes s'appuient sur les cames en S et W. --- The two cams 4a-4b are housed in the recesses 7 of said rotor. the pallets 3a-3c apply against the flange 12, e 'are housed in the slots of the rotor. the ends 14 of said pallets rest on the S and W cams.
