Abstract

The disc shaped seal is made of flexible material with a hole in its centre. This is compressed to be in contact with a cheek surface, so that it is slightly deformed in its radial direction. The pressure required to achieve sealing is produced at the inner surface of a cylinder and the outer surface of a shaft. A fixed seal (6) seats in a groove (15) in a fixed blade (4) on a cylinder (2), held by bolts (11) and the sliding seal (7) fits in a movable blade groove (16), fixed by a bolt (10) on a shaft. (3).

Description

La présente invention concerne un actionneur rotatif du type à ailettes. Un objet de la présente invention est un actionneur rotatif du type à ailettes dans lequel les fuites provenant de la circonférence extérieure d'une garniture disposée de manière à pouvoir coulisser sont totalement empêchées par la formation d'une surface coulissante continue qui a la même section en coupe que la circonférence extérieure de la garniture. The present invention relates to a rotary actuator of the fin type. An object of the present invention is a rotary actuator of the fin type in which the leaks coming from the external circumference of a lining arranged so as to be able to slide are completely prevented by the formation of a continuous sliding surface which has the same section. in section as the outer circumference of the gasket.

La présente invention sera bien comprise lors de la description suivante faite en liaison avec les dessins ci-joints dans lesquels
La figure 1 est une vue en coupe d'un mode de réalisation de la présente invention; et
La figure 2 est une vue en coupe prise le long de la ligne A-B de la figure 1.
The present invention will be understood from the following description given in conjunction with the accompanying drawings in which
Figure 1 is a sectional view of an embodiment of the present invention; and
Figure 2 is a sectional view taken along the line AB in Figure 1.

En liaison avec la figure 2, une garniture fixe 6 est montée dans une rainure 15 d'une ailette fixe 4, qui est fixée à un cylindre 2 par un boulon 11. Une garniture pouvant coulisser 7 est montée dans une rainure 16 d'une ailette mobile 5, qui est fixée a un arbre 3 par un boulon 10. In connection with FIG. 2, a fixed lining 6 is mounted in a groove 15 of a fixed fin 4, which is fixed to a cylinder 2 by a bolt 11. A sliding lining 7 is mounted in a groove 16 of a movable fin 5, which is fixed to a shaft 3 by a bolt 10.

En liaison maintenant avec la figure 1, chacune des plaques d'étanchéité 8 est disposée avec sa périphérie légèrement comprimée par la surface intérieure du cylindre 2 dans le sens radial de celui-ci, alors que le trou médian de chaque plaque se détend légèrement à partir de la surface circonférentielle extérieure de la partie cylindrique d'un arbre 3. L'arbre 3 est supporté en rotation par des roulements 9 au centre du cylindre 2. La face circonférentielle intérieure de la plaque 8 et la surface cylindrique de l'arbre 3 sont engagées en coulissement. Chacun des couvercles 1 placés aux deux extrémités est fixé au cylindre 2 par des boulons 14. Now in connection with FIG. 1, each of the sealing plates 8 is arranged with its periphery slightly compressed by the interior surface of the cylinder 2 in the radial direction thereof, while the median hole of each plate slightly relaxes from the outer circumferential surface of the cylindrical part of a shaft 3. The shaft 3 is rotatably supported by bearings 9 in the center of the cylinder 2. The inner circumferential face of the plate 8 and the cylindrical surface of the shaft 3 are engaged in sliding. Each of the covers 1 placed at the two ends is fixed to the cylinder 2 by bolts 14.

De nouveau en liaison avec la figure 2, le cylindre 2 comporte des orifices d'entrée et de sortie de fluide 12 et 13.L'arbre sur lequel est montée l'ailette mobile 5 est disposé de façon à pouvoir tourner vers la droite et vers la gauche selon que le fluide entre dans les orifices 12 et 13 ou en sort. Again in connection with FIG. 2, the cylinder 2 has fluid inlet and outlet ports 12 and 13. The shaft on which the movable fin 5 is mounted is arranged so that it can rotate to the right and to the left depending on whether the fluid enters or leaves the orifices 12 and 13.

Une caractéristique de la présente invention réside dans l'agencement de chaque plaque d'étanchéité 8. La plaque d'étanchéité 8 a un bord circonférentiel extérieur 17 et un bord circonférentiel intérieur 18 affilé et est placée en position avec un certain degré de déformation conféré dans la direction radiale. L'agencement évite qu'une fuite ne se produise entre la surface cylindrique et la face de contact comprimée de la plaque d'étanchéité 8 à la fois dans le sens axial et dans le sens circonférentiel. Les faces contiguës aux garnitures 6 et 7 sont disposées de façon à être parfaitement continues.Dans le cas présent, la déformation conférée > la plaque d'étanchéité 8 par la pression du fluide ne se produit que dans le sens de son épaisseur et, comme les faces- circonférentielles extérieure et intérieure de la plaque 8 peuvent coulisser dans le sens de son épaisseur, les parties de bord 17 et 18 de la plaque restent non déformées. A feature of the present invention resides in the arrangement of each sealing plate 8. The sealing plate 8 has an outer circumferential edge 17 and an inner circumferential edge 18 sharpened and is placed in position with a certain degree of deformation imparted in the radial direction. The arrangement prevents leakage from occurring between the cylindrical surface and the compressed contact face of the sealing plate 8 both in the axial direction and in the circumferential direction. The faces contiguous to the linings 6 and 7 are arranged so as to be perfectly continuous. In the present case, the deformation imparted> the sealing plate 8 by the pressure of the fluid occurs only in the direction of its thickness and, as the outer and inner circumferential faces of the plate 8 can slide in the direction of its thickness, the edge portions 17 and 18 of the plate remain undeformed.

En outre, un mouvement excentrique de l'arbre 3 dû au tolérance d'usinage et au jeu des roulements 9 est absorbé par la déformation élastique de la plaque 8 dans sa direction radiale. Par conséquent, les faces continues de la plaque d'étanchéité 8 restent non affectées par un tel mouvement excentrique. In addition, an eccentric movement of the shaft 3 due to the machining tolerance and the play of the bearings 9 is absorbed by the elastic deformation of the plate 8 in its radial direction. Consequently, the continuous faces of the sealing plate 8 remain unaffected by such an eccentric movement.

La plaque d'étanchéité 8 de la présente invention est constituée d'un matériau choisi de préférence dans le groupe formé du matériau dit'nylon, du polyéthylène de poids moléculaire ultra-élevé, de caoutchouc de polyuréthane, etc. Des matériaux pouvant etre envisagés à cette fin comprennent un complexe constitué de caoutchouc de polyuréthane et de fluororésine, un complexe constitué de métal et d'un caoutchouc synthétique et analogue. The sealing plate 8 of the present invention is made of a material preferably chosen from the group consisting of dit'nylon material, ultra-high molecular weight polyethylene, polyurethane rubber, etc. Possible materials for this purpose include a complex made of polyurethane rubber and fluororesin, a complex made of metal and a synthetic rubber and the like.

La présente invention n'est pas limitée aux exem plues de réalisation qui viennent d'être décrits, elle est au contraire susceptible de modifications et de variantes qui apparattront à l'homme de l'art.  The present invention is not limited to the exemplary embodiments which have just been described, it is on the contrary liable to modifications and variants which will appear to those skilled in the art.
