Abstract

A rotor (2) rotates in a stator (1). It drives or is driven by vanes (6), the centre point being that of the rotor (CR) and a tangent point (TR) of the latter being different from the tangent point (TS) of the stator. The vanes are guided by means of running rollers (8) fixed to the bottom of the vanes and, during assembly, engaged in a running track (7) formed in the side walls, thus eliminating centrifugal friction. Moreover, seated in a recess of the vanes are two vanes guide rollers (5) which run in the receptacle (4) formed in the rotor, thus eliminating rolling friction. The profile of the running track, shown here as circular with as its centre point that of the stator, must be in a relation to the inner profile of the stator, whatever this may be. End sealing is obtained by a set of standard sealing rings. <IMAGE>

Description

La presente invention consiste à obtenir dans les machines rotatives a palettes connues dans leur principe, un perfectionnement portant sur les besoins d'une étanchéité parfaite et d'une sup - pression tant des frottements de glissement de ces palettes que de leur frottement centrifuge et permettre ainsi des utilisations industrielles pour lesquelles ces machines ne peuvent pas être employées.The present invention consists in obtaining in rotary vane machines known in their principle, an improvement relating to the needs of a perfect seal and of a pressure - both the sliding friction of these pallets and their centrifugal friction and allow thus industrial uses for which these machines cannot be used.

L'utilisation de telles machines est limitée actuellement à de petites machines n'ayant de volumétriques que le nom en raison de leur absence d'étanchéité réelle d'une part et de la pression centrifuge des palettes contre le rotor d'autre part, faisant ainsi un freinage de plus en plus efficace avec l'augmentation de la rotation.The use of such machines is currently limited to small machines having volumetrics only the name because of their lack of real tightness on the one hand and the centrifugal pressure of the pallets against the rotor on the other hand, making braking more and more effective with increasing rotation.

De ce qui précède, il découle que malgré des avantages certains que de telles machines devraient procurer dans le cas où la prolongation de la détente impossible à obtenir dans les machines classiques à pistons notamment pour des moteurs thermiques, où dans la prolongation de la compression avec un amoindrissement de la section dû au retrait progressif des palettes au fur et à mesure de leur rotation permet de monoétager l'obtention directe d'une pression élevée.From the foregoing, it follows that despite certain advantages that such machines should provide in the event that the extension of the expansion is impossible to obtain in conventional piston machines, in particular for heat engines, or in the extension of compression with a reduction in the section due to the progressive withdrawal of the pallets as and when they rotate makes it possible to mono-stage the direct obtaining of a high pressure.

Les conséquences de cette imperfection font que de telles machines ne sont utilisées que pour de petits compresseurs ou engins similaires avec un mauvais rendement volumétrique, impossibles à utiliser tant que le régime de rotation n'est pas suffisant pour faire agir la force centrifuge qui provoque le mouvement d'extension des palettes.The consequences of this imperfection mean that such machines are only used for small compressors or similar machines with poor volumetric efficiency, impossible to use. read as long as the rotation speed is not sufficient to activate the centrifugal force which causes the pallet to extend.

En remédiant à ces imperfections, la présente invention ouvre à de tels engins un créneau d'utilisation considérable, car l'emploi du procédé, non seulement améliore les fonctions dans le domaine où ils sont actuellement employés mais la construction de pompes et compresseurs à fort débit devient possible de même que celle de tous moteurs thermiques où à vapeur dans lesquels la détente la plus complète possible est un facteur d'économie considérable d'énergie qui ne peut être obtenu dans un moteur à pis - tons.By remedying these imperfections, the present invention opens up such a considerable niche for such machines, because the use of the process not only improves the functions in the field where they are currently used but the construction of pumps and compressors at high flow becomes possible as well as that of all thermal or steam engines in which the most complete expansion possible is a factor of considerable energy saving which cannot be obtained in a piston engine.

Pour apprécier la nouvelle utilisation de ces moteurs, si nous prenons l'exemple d'une machine à vapeur classique, nous consta - tons que sa détente n'est obtenue que par l'emploi de 2 cylindres de diamètre différent. Il en serait de même dans un moteur ther- mique, mais le passage d'un cylindre de petit diamètre à un cylindre de plus gros diamètre entraîne à une baisse immédiate de pression préjudiciable au rendement et si l'on procédait à l'inverse en admettant dans un petit cylindre un mélange gazeux que l'on transférerait dans un plus gros cylindre, une machine à piston ne peut valablement profiter d'un temps de travail qui dans le meilleur cas n'est que de la moitié de celui de la vitesse de propagation de la flamme soit pour 30 mètres/seconde une vitesse de descente de 15 mètres seulement.To appreciate the new use of these engines, if we take the example of a classic steam engine, we note that its expansion is only obtained by the use of 2 cylinders of different diameter. It would be the same in a motor t h er nomic, but the passage of a cylinder of small diameter to a cylinder of larger diameter leads to an immediate drop in pressure detrimental to the performance and if we proceeded to reverse by admitting in a small cylinder a gaseous mixture which one would transfer in a larger cylinder, a machine with piston cannot validly profit from a working time which in the best case is only half of that of the speed of propagation of the flame is for 30 meters / second a descent speed of only 15 meters.

Dans une machine rotative à palettes, un moteur peut être obtenu en utilisant 2 chambres voisines, l'une faisant l'admission et la pré-compression, l'autre le travail moteur et la détente, mais celle-ci n'est limitée que par la vitesse circonférentielle/se- conde(ainsi que les autres temps). Tout se passe en continu, et alors que la détente vraie n'est obtenue dans un moteur à pistons que sur une hauteur moyenne d'environ les 7/8èmes de sa course de descente, dans un moteur a palettes bénéficiant des améliorations de la présente invention, la détente peut être effectuée à volonté du constructeur au moment où le volume détendu est supérieur au volume admis. En exemple non limitatif, une détente à 130 % malgré la baisse de pression moyenne qu'elle implique n'a pas d'influence sur le régime d'utilisation mais procure une économie d'environ 25 à 30 % de carburant.In a rotary vane machine, a motor can be obtained by using 2 adjoining chambers, one for admission and pre-compression, the other for engine work and expansion, but this is only limited by the circumferential speed / second (as well as the other times). Everything happens continuously, and while true expansion is only obtained in a piston engine over an average height of about 7 / 8ths of its downward stroke, in a paddle engine benefiting from the improvements of the present invention, expansion can be carried out at will of the manufacturer when the relaxed volume is greater at the admitted volume. In a nonlimiting example, an expansion to 130% despite the average pressure drop that it implies has no influence on the operating regime but provides a saving of about 25 to 30% of fuel.

Autre conséquence indirecte de l'utilisation de ces machines, dans un moteur à vapeur par exemple, en raison du travail en continu dans la même chambre, le taux d'admission peut être déterminé par le nombre de pales et la détente la plus basse qu'il est possible d'obtenir peut être telle qu'elle amène la suppression du condensateur, permettant ainsi un fonctionnement en circuit fermé permettant l'emploi d'autres facteurs de vaporisation que l'eau distillée (mélange eau/alcool par exemple) facilitant la vaporisation et économisant les calories de production de vapeur.Another indirect consequence of the use of these machines, in a steam engine for example, due to the continuous work in the same chamber, the admission rate can be determined by the number of blades and the lowest trigger that '' it is possible to obtain, perhaps, such that it leads to the elimination of the capacitor, thus allowing operation in a closed circuit allowing the use of other vaporization factors than distilled water (water / alcohol mixture for example) facilitating vaporizing and saving the calories of steam production.

Ce qui précède a à seul titre d'exemple des conséquences direc - tes ou indirectes que l'invention permet d'envisager sans limitation.The foregoing has only as an example direct or indirect consequences which the invention makes it possible to envisage without limitation.

La présente invention utilise un moteur rotatif à palettes dans lequel la ou les palettes dont le nombre est fonction du meilleur usage auquel est destiné la machine ne sont plus projetées par la force centrifuge mais parle mouvement de rotation qui les contraint à un va et vient par le moyen d'un cnemin de roulement. Ces machines peuvent donc remplir leur fonction à tous les régimes sans avoir de point mort au moment du départ. L'effet de frein centrifuge est également supprimé de ce fait, l'étanchéité entre palette et sat- tor étant assuré par une segmentation ordinaire sur lequel l'effet centrifuge est négligeable en raison du faible poids de ce ou de ces segments.The present invention uses a rotary vane motor in which the pallet or pallets, the number of which is a function of the best use for which the machine is intended, are no longer projected by centrifugal force but speak of rotational movement which forces them to come and go by means of a rolling path. These machines can therefore fulfill their function at all speeds without having neutral at the time of departure. The centrifugal brake effect is therefore also eliminated, the sealing between the pallet and the saturator being ensured by ordinary segmentation on which the centrifugal effect is negligible due to the low weight of this or these segments.

Le frottement de glissement du va et vient de la palette est également supprimé et remplacé par un frottement de roulement , lui- même négligeable en raison de la faible vitesse seconde de ce va et vient.The sliding friction of the back and forth of the pallet is also eliminated and replaced by a rolling friction, itself negligible due to the low second speed of this back and forth.

La figure 1 représente une coupe verticale pouvant également se concevoir en plan, d'une cellule dans laquelle la partie de la gauche de l'axe vertical est figuré vue sur un flanc comportant le chemin de roulement, rotor enlevé, la partie à droite de cet axe étant figurée avec un retor supposé à 4 pales et muni de ses palettes. Le Stator (1) est figure avec un vide supposé de 2 lu - miêres dont le développé et la position ne sont que facultatives, cha-que machine suivant sa destination, sa fonction et son nombre de palettes qui ne sera pas le même pour une pompe à liquide (incompressible) que pour des fluides gazeux à tout moment de leur état.FIG. 1 represents a vertical section which can also be conceived in plan, of a cell in which the part of the left of the vertical axis is represented seen on a side comprising the raceway, rotor removed, the part to the right of this axis being shown with a supposed rotor with 4 blades and fitted with its paddles. The Stator (1) is shown with an assumed vacuum of 2 liters - materials whose development and position are only optional, each machine depending on its destination, its function and its number of pallets which will not be the same for a liquid pump (incompressible) only for gaseous fluids at any time in their state.

Entre le rotor (2°) et le stator (1) on obtient la chambre de travail (3) fractionnable ou non suivant le nombre de palettes(6). Le centre de rotation du rotor (CR°) est différent de celui sus- tator (CS) qui est fixe et ne sert que de centrage au chemin de roulement (7) pour les galets de guidage (8) commandant le va et vient des palettes qui sont ainsi soumises à des efforts imposés par :

  • - la pression donnée ou reçue sur la face de travail saillante hors rotor
  • - Le coulissement des palettes dans le logement (4) du rotor et qui est toujours perpendiculaire au point de centre (CR) du rotor.
Between the rotor (2 °) and the stator (1) we obtain the working chamber (3) which can be split or not depending on the number of pallets (6). The center of rotation of the rotor (CR °) is different from that of the sus- tator (CS) which is fixed and only serves as centering on the raceway (7) for the guide rollers (8) controlling the comings and goings of the pallets which are thus subjected to forces imposed by:
  • - the pressure given or received on the projecting working surface outside the rotor
  • - The sliding of the vanes in the housing (4) of the rotor and which is always perpendicular to the center point (CR) of the rotor.

Bien que la distance entre l'axe du chemin de roulement (7) et la paroi intérieure du stator soit toujours la même, le point de tangente (TR) de la palette ne correspondant pas au point de tangente du stator(TS) lequel a pour centre le point (CS) et comme point de pivotement le point (AP). Ceci crée pendant la rotation des an - gles pendant lesquels la palette n'est pas en contact absolu avec le stator dans les limites très infimes mais nécessitant néammoins une segmentation d'étanchëité en bout de palette.Although the distance between the axis of the raceway (7) and the inner wall of the stator is always the same, the tangent point (TR) of the pallet does not correspond to the tangent point of the stator (TS) which has to center the point (CS) and as a pivot point the point (AP). This creates angles during rotation during which the pallet is not in absolute contact with the stator within very small limits but requiring nevertheless a segmentation of sealing at the end of the pallet.

Pour sustituer un mouvement de roulement au lieu du frottement de glissement de la palette dans son logement (4) ménagé dans le rotor, la palette comporte des bagues de roulement (5) à raison de 2 par palette pour éviter un.mouvement de bascule, ces bagues pivotant sur un axe passant dans le milieu de la palette dans le sens de son épaisseur . Les bagues de roulement sont usinées au diamètre supérieur à l'épaisseur des palettes donnant un jeu de quelques centièmes a 1/10 ème de millimètre suivant les cas, pour supprimer tout frottement de glissement. L'étanchéité est obtenue par segmentation ordinaire.To replace a rolling movement instead of the sliding friction of the pallet in its housing (4) formed in the rotor, the pallet has bearing rings (5) at a rate of 2 per pallet to avoid a rocking movement, these rings pivoting on an axis passing through the middle of the pallet in the direction of its thickness. The bearing rings are machined to a diameter greater than the thickness of the pallets giving a play of a few hundredths to 1/10 th of a millimeter depending on the case, for sup override any sliding friction. The seal is obtained by ordinary segmentation.

Le nombre de pales commandées par la rotation du rotor est en raison de la fonction de la machine. L'étancheité en point mort entre le rotor (2) et le stator (1) peut être obtenue soit direc- tement par un usinage convenable lorsqu'il s'agit d'un lfuide liquide, mais une étanchéité plus efficace peut être obtenue lorsqu'il s'agit de fluides gazeux, par le moyen d'un segment supé - rieur (11) maintenu en pression constante sur le rotor par le moyen d'un ressort (12) le tout encastré dans un logement usiné dans le stator. La partie inférieure, en contact avec le rotor doit être profilée au même diamètre ou rayon du rotor et comporter un adoucissement de cette pente du côté inverse à la rotation de manière à ne pas subir ou occasionner des chocs lors du passage des segments des palettes, très exactement à la manière dont agit une came quelconque.The number of blades controlled by the rotation of the rotor is due to the function of the machine. The tightness in the neutral between the rotor (2) and the stator (1) can be obtained either di r ec ment by suitable machining in the case of a liquid lfuide, but a more effective seal can be obtained in the case of gaseous fluids, by means of an upper segment (1 1 ) maintained at constant pressure on the rotor by means of a spring (12) all encased in a housing machined in the stator. The lower part, in contact with the rotor must be profiled to the same diameter or radius of the rotor and include a softening of this slope on the opposite side to the rotation so as not to undergo or cause shocks during the passage of the segments of the pallets, very exactly the way any cam works.

La figure 2 représente un dessin d'une palette compléte. La palette (6) comporte en saillie en partie basse de chacune de ses extrémités dans le sens de la longueur des galets de roulement (8) qui devront circuler dans les chemins de roulement figurés en (7) sur la figure précédente. C'est la combinaison du roulement de ces galets dans le chemin qui leur est propre (opération effectuée au montage) qui maintient le contact plus ou moins relatif selon l'angle de rotation, avec la paroi intérieure du stator. Le haut de la palette est profilé en arc de cercle dont le rayon a comme point de centre (environ) l'axe de pivotement des galets de roulement.Figure 2 shows a drawing of a complete palette. The pallet (6) has projecting in the lower part of each of its ends in the direction of the length of the rollers (8) which must circulate in the raceways shown in (7) in the previous figure. It is the combination of the bearing of these rollers in their own path (operation carried out during assembly) which maintains more or less relative contact according to the angle of rotation, with the internal wall of the stator. The top of the pallet is profiled in an arc, the radius of which has as its center point (approximately) the pivot axis of the rollers.

La palette comporte en son milieu dans le sens de la longueur un évidement pour le logement des galets de guidage (5). L'étanchéité est assurée dans toutes les positions par les segments centrifuges (9) et par les segments latéraux (10) qui en partie d'excentre- ment maximum ne doivent pas sortir du logement des palettes pra-tiquées dans le rotor.The pallet has in its middle in the direction of the length a recess for the housing of the guide rollers (5). The sealing is provided in all positions by centrifugal segments (9) and the lateral segments (10) partly lies excentre- maximum should not leave the p r pallet housing has tiquées in the rotor.

Pour des pompes, des compresseurs, des machines à vapeur n'ayant plus besoin d'être bi-étagés puisque la détente complète peut être obtenue, directement une seule cellule peut suffire comme décrit et représenté. Par contre, pour des moteurs thermiques ou tout autre machine nécessitant une précompression du fluide avant sa détente deux cellules accouplees sur le même arbre ou en opposé sur un arbre parallèle sont nécessaires, le passage du fluide d'une cellule dans l'autre s'effectuant par tout moyen classique, soupape ou distributeur selon les besoins et la disposition choisie.For pumps, compressors, steam engines no longer require to be two-stage as complete relaxation can be obtained directly a single cell can suffice as d e crit and represented. On the other hand, for heat engines or any other machine requiring precompression of the fluid before its expansion two cells coupled on the same shaft or opposite on a parallel shaft are necessary, the passage of the fluid from one cell to the other is performing by any conventional means, valve or distributor according to the needs and the chosen arrangement.

Dans tous les cas, que les machines construites avec le présent procédé comportent une ou deux cellules pour leur fonctionnement, ces machines peuvent être groupées en ligne, en parallèle ou en oppose sur un même arbre avec ou sans renvoi sur un arbre central. L'étanchéité étant dans tous les cas assurée et les échauffements de pièces en mouvements supprimés avec la disparition du frottement de glissement, certaines machines peuvent être réalisées en abandonnant l'utilisation des métaux, ferreux ou alumineux et de leur substituer des matériaux plastiques aussi bien pour des organes vitaux que pour des segments d'étancnéité. Un peut par exem- ple, en utilisant le procédé realiser des pompes de très fort débit antidéflagrantes à 100 %.In all cases, whether the machines constructed with the present method comprise one or two cells for their operation, these machines can be grouped in line, in parallel or in opposition on the same shaft with or without reference to a central shaft. The sealing being in all cases ensured and the heating of moving parts eliminated with the disappearance of sliding friction, certain machines can be produced by abandoning the use of metals, ferrous or aluminous and substituting plastic materials for them as well for vital organs than for sealing segments. A can for exa m - ple, using the method realize pumps of very high throughput flameproof 100%.

This path guides the rollers which are integral with the pallet so that the width thereof corresponds to the distance from the crown having for large diameter that of the stator and for small diameter the axis of the raceway where circulate the pallet rollers. 3 - Dispositif selon les revendications 1 et 2 prises ensemble et caractérisé par le fait que ce dispositif supprime l'effort centrifuge de frottement des palettes, permet un départ facile par - tant de zéro, supprime les temps morts de mise en route et l'ac - tion de frein centrifuge des systèmes actuels.3 - Device according to claims 1 and 2 taken together and characterized in that this device eliminates the centrifugal force of friction of the pallets, allows an easy start by - both from zero, eliminates the idle time and centrifugal brake action of current systems. 4 - Dispositif selon la revendication 1 et caractérisé par le fait que chaque palette comporte en partie inférieure un évidement permettant le logement de galets de guidage d'un diamètre légèrement supérieur à l'affleurement des faces de la palette et inférieur d'un jeu normal à la rainure de logement de celle-ci. La palette n'a plus de frottement de glissement mais seulement un frottement de roulement de ses propres galets de guidage dont la position parallèle empêche également tout mouvement de bascule.4 - Device according to claim 1 and characterized in that each pallet comprises in the lower part a recess allowing the housing of guide rollers with a diameter slightly greater than the surface of the faces of the pallet and lower than a normal clearance to the housing groove thereof. The pallet no longer has sliding friction but only rolling friction from its own guide rollers whose parallel position also prevents any rocking movement. 5 - Dispositif selon les revendications 1, 2, 3 et 4 prises ensemble et caractérisé par le fait que malgré le guidage en maintien d'écartement des palettes contre le stator, le point de centre des palettes donnant à celles-ci un angle différent de ce qu'il devrait être pour avoir une efficacité totale d'étanchéité, ce qui nécessiterait le point de centre du stator comme base du rayon, l'extrémité de la palette est incurvé suivant un profil de base qui égal à un rayon partant de son angle de pivotement à l'axe du galet de roulement et le dôme du profil est égal à la largeur de la couronne partant de l'axe du chemin de roulement. Cette étancheité est complétée par ure segmentation courante dont le logement est de préférence ménagé dans la palette elle-même.5 - Device according to claims 1, 2, 3 and 4 taken together and characterized in that despite the guide in maintaining spacing of the pallets against the stator, the center point of the pallets giving them an angle different from what it should be to have a total sealing efficiency, which would require the center point of the stator as the base of the radius, the end of the pallet is curved according to a basic profile which equal to a radius starting from its pivoting angle to the axis of the roller and the dome of the profile is equal to the width of the crown starting from the axis of the raceway. This tightness is supplemented by ure current segmentation, the housing of which is preferably provided in the pallet itself. 6 - Dispositif selon les revendications 1,2, 3, 4 et 5 prises ensemble et caracterisé par le fait que l'ensemble du système de guidage des palettes ne se limite pas à l'application d'une utilisation du mouvement dans des figures géométriques seulement circulaires, le procède étant également valable pour des figures de tout profil, elliptiques, ovoïdes, ou autres sous réserve que le :hemin de roulement soit adapté au profil du stator pour mainte- air le même écartement du mouvement d'excentrement de la palette.6 - Device according to claims 1 , 2, 3, 4 and 5 taken together and characterized by the fact that the entire pallet guide system is not limited to the application of the use of movement in geometric figures only circular, the process also being valid for any profile, elliptical, ovoid, or other, provided that the rolling path is adapted to the profile of the stator for mainteer the same spacing of the eccentric movement of the pallet .
