Abstract
Description
Il est connu de realiser des pompes ou moteurs hvdrauliques à pales multiples mobiles radialement. I1 est connu également de réaliser ces pompes ou moteurs selon une dispositinn syme- trique par rapport à un plan passant par l'axe afin d'équilibrer les efforts sur le rotor et d'augmenter le débit donc la puissance.It is known to produce hydraulic pumps or motors with multiple blades that can move radially. It is also known to produce these pumps or motors according to a symmetrical arrangement with respect to a plane passing through the axis in order to balance the forces on the rotor and to increase the flow rate, therefore the power.
Ces pompes ou moteurs à pales qui sont moins encombrants et plus légers que les pompes ou moteurs à pistons n'ont pas le développement de ces derniers parce qu'elles sont moins fiables avec un rendement inférieur.These pumps or motors with blades which are less bulky and lighter than pumps or motors with pistons do not have the development of the latter because they are less reliable with a lower efficiency.
L'invention, objet du présent brevet, remedie à ces inconvénient s et permet de réaliser des pompes ou moteurs à pales radiales légers et peu encombrants avec un bon rendement et une grande fiabilité.The invention which is the subject of this patent overcomes these drawbacks and makes it possible to produce pumps and motors with light and space-saving radial blades with good efficiency and high reliability.
Elle est caractérisee en ce que les pales d'un contour rectangulaire ne se déplacent dans les rainures du rotor que lorsque la différence de pression sur leurs faces opposées est nulle.It is characterized in that the blades of a rectangular contour move in the grooves of the rotor only when the pressure difference on their opposite faces is zero.
A cet effet le stator est caractérise en ce qu'il comporte deux fois deux secteurs cylindriques circulaires opposés deux à deux et à ùi l'un de l'autre, un groupe de ces secteurs op poss corresponnant à l'excentrement maximum des pales - grand diamètre-et l'autre groupe ds ces secteurs opposés à ff des
7 premières correspondant à l'excentrement minimum des pales-ne- tit diamètre
Selon l'invention, l'angle au centre de ces secteurs cylindres ques circulaires est au moins l'angle au centre de deux pales successives matérialisé par les rainures du rotor.To this end, the stator is characterized in that it comprises twice two circular cylindrical sectors opposite two by two and at each other, a group of these sectors op poss corresponding to the maximum eccentricity of the blades - large diameter - and the other group in these sectors opposite to ff
7 first ones corresponding to the minimum eccentricity of the blades-titanium diameter
According to the invention, the angle at the center of these circular cylinder sectors is at least the angle at the center of two successive blades materialized by the grooves of the rotor.
Ces quatre secteurs cylindriques circulaires sont raccords, selon l'invention, par quatre secteurs cylindriques évolutifs de profil identique caractérisé en ce qu'il comporte une partie plane tangente aux secteurs cylindriques circulaires de petit diamètre à l'une de ses extrêmités et à un secteur cylindrique circulaire de raccordement avec les secteurs cylindriques circulaires de grand diamètre à son autre extrémité.These four circular cylindrical sectors are connected, according to the invention, by four evolving cylindrical sectors of identical profile characterized in that it comprises a flat part tangent to the circular cylindrical sectors of small diameter at one of its ends and to a sector. cylindrical circular connection with circular cylindrical sectors of large diameter at its other end.
Le rotor est caractérisé en ce qu'il porte sur chaque face d'extrêmité et au niveau du pied des rainures de pales une eor ge circulaire coaxiale.The rotor is characterized in that it carries on each end face and at the foot of the blade grooves a coaxial circular eor ge.
Les pales sont maintenues en contact avec la partie intérieure à cylindres multiples du stator par deux cames conjuguées solidaires des faces du stator et trouvant leur place dans les gorges circulaires des faces d'extremité du stator, ces cames agissant sur les extrémités intérieures des pales rectangulaires.The blades are kept in contact with the inner multi-cylinder part of the stator by two conjugate cams integral with the faces of the stator and finding their place in the circular grooves of the end faces of the stator, these cams acting on the inner ends of the rectangular blades. .
D'autres caractéristiques de l'invention seront précisées au cours de la description qui suit donnée uniquement à titre d'exemple de réalisation.Other characteristics of the invention will be specified during the description which follows, given solely by way of example of embodiment.
A la planche unique la figure (1) est une coupe par un plan médian perpendiculaire à l'axe de rotation, suivant I I de la figure (2), d'un moteur ou pompa selon l'invention.On the single board, figure (1) is a section through a median plane perpendicular to the axis of rotation, along I I of figure (2), of a motor or pump according to the invention.
La figure (2) est une coupe longitudinale par un plan contenant l'axe de rotation suivant II II de la figure (1). Figure (2) is a longitudinal section through a plane containing the axis of rotation along II II of Figure (1).
Aux figures (1 et 2) : le corps central 1 du stator a sa par- tie intérieure formée de secteurs cylindriques différents selon l'invention se raccordant entre eux tangentiellement. Les secteurs cylindriques circulaires de petit diamètre 2 diamètralement opposés sont raccordés aux secteurs cylindriques circulaires de grand diamètre 3 diamètralement opposés par des secteurs cylindriques complexes de meme profil composés d'une partie plane 4 tangente aux secteurs 2 à leurs extremités ces parties planes 4 étant raccordées tangentiellement aux secteurs 3 par les secteurs cylindres circulaires 5.
In FIGS. (1 and 2): the central body 1 of the stator has its internal part formed by different cylindrical sectors according to the invention which connects to each other tangentially. The circular cylindrical sectors of small diameter 2 diametrically opposed are connected to the circular cylindrical sectors of large diameter 3 diametrically opposed by complex cylindrical sectors of the same profile composed of a plane part 4 tangent to the sectors 2 at their ends, these plane parts 4 being connected tangentially to sectors 3 by circular cylinder sectors 5.
Le rotor 6 concentrique aux secteurs circulaires 2 et 3 du stator 1 porte des fentes 7 régulièrement espacées - 9 à 400 dans l'exemple représenté.The rotor 6 concentric to the circular sectors 2 and 3 of the stator 1 carries slots 7 regularly spaced - 9 to 400 in the example shown.
Dans ces fentes 7 se déplacent radialement les pales rectangulaires 8.In these slots 7, the rectangular blades 8 move radially.
Le rotor 6 porte latéralement et selon l'invention les gorges concentriques 9.The rotor 6 carries laterally and according to the invention the concentric grooves 9.
Les cames 10 conjuguées de la partie intérieure du stator 1 sont fixées sur les faces Il du stator - ou en font partie leur partie active étant selon l'invention à l'intérieur des gorges 9.The cams 10 conjugate of the internal part of the stator 1 are fixed on the faces II of the stator - or form part of it their active part being according to the invention inside the grooves 9.
Le rotor 6 est prolongé symétriquement et coaxialement par les axes 12 tournant dans les alésages 13 solidaires des faces Il du stator. The rotor 6 is extended symmetrically and coaxially by the axes 12 rotating in the bores 13 integral with the faces II of the stator.
Selon l'invention le jeu entre les axes 12 et les alésages 13 est déterminé pour réaliser l'étanchéité à la pression sans l'interposition d'un joint spécifique autre ou'un joint de sortie sans pression.According to the invention, the clearance between the axes 12 and the bores 13 is determined to achieve pressure tightness without the interposition of a specific other seal or an outlet seal without pressure.
On voit clairement que les pales rectanaulaires 8 sont obligées par l'action, sur leur extremité intérieure, des cames 10 d'etre en contact permanent avec la surface cylindrique complexe interne du stator 1. Le fluide arrivant par les entrées opposées 14 et sortant par les sorties opposées 15, ou réciproquement, on voit qu'il n'y a une différence de pression sur les faces des pales que lorsqu'elles sont en contact avec les secteurs 2 et 3 pendant lesquelles elles sont fixes oar rapport au rotor, l'angle actif de ces secteurs étant limité nar les ouvertures circonférentielles 16 et 17 par lesquelles le fluide arrive ou sort des capacités variables limitées par les pales 8.It is clearly seen that the rectanaular blades 8 are forced by the action, on their inner end, of the cams 10 to be in permanent contact with the internal complex cylindrical surface of the stator 1. The fluid arriving by the opposite inlets 14 and leaving by the opposite outputs 15, or vice versa, it can be seen that there is a pressure difference on the faces of the blades only when they are in contact with the sectors 2 and 3 during which they are fixed oar relative to the rotor, l the active angle of these sectors being limited by the circumferential openings 16 and 17 through which the fluid arrives or leaves variable capacities limited by the blades 8.
Le mouvement du fluide à l'extérieur du rotor, c' est-à-dire dans la partie active, correspond exactement au débit et dans son sens, donc procure le minimum de pertes. Le débit du flui- de dans les gorges 9 est engendré par le débit des pales sur elles-memes : il est faible avec de faibles vitesses donc avec pertes réduites.The movement of the fluid outside the rotor, that is to say in the active part, corresponds exactly to the flow rate and in its direction, therefore provides the minimum of losses. The flow rate of the fluid in the grooves 9 is generated by the flow rate of the blades on themselves: it is low with low speeds therefore with reduced losses.
Pour les pompes ayant un nombre de tours par minute suffisant il est possible de supprimer les cames 10 dont l'effet est remplacé par la force centrifuge. For pumps with a sufficient number of revolutions per minute, it is possible to omit the cams 10, the effect of which is replaced by centrifugal force.
