rieur du bord terminal de l'attache filetée, l'âme intérieure présentant, à son extrémité qui se termine avant l'extrémité de la partie extérieure, un évasement à surface terminale conique opposée à celle de la partie extérieure. Dans le raccord selon l'invention, l'embout présente, à l'extrémité non filetée, une partie annulaire ayant une surface intérieure conique conçue pour s'accoupler à la surface terminale conique de la partie laughing at the end edge of the threaded fastener, the inner core having, at its end which ends before the end of the outer part, a flare with a conical end surface opposite to that of the outer part. In the connector according to the invention, the end piece has, at the non-threaded end, an annular part having a conical inner surface designed to mate with the conical end surface of the part

La partie annulaire à surface conique de l'embout présente, dans sa zone de plus petit diamètre, une gorge d'écoulement conçue pour permettre la déformation du corps d'étanchéité; afin de permettre le montage, par rapport au diamètre du filet de l'attache et au diamètre du corps d'étanchéité, la partie annulaire peut être reliée à la partie restante de l'embout au moyen d'un filetage, avantageusement à pas à gauche, afin d'en The annular part with conical surface of the end piece has, in its zone of smaller diameter, a flow groove designed to allow the deformation of the sealing body; in order to allow mounting, with respect to the diameter of the thread of the fastener and the diameter of the sealing body, the annular part can be connected to the remaining part of the end piece by means of a thread, advantageously step by step left, in order to
empêcher le desserrrage pendant le serrage du raccord. prevent loosening while tightening the fitting.
Diverses autres caractéristiques de l'invention Various other features of the invention
ressortent d'ailleurs de la description détaillée qui moreover emerge from the detailed description which
suit. Une forme de réalisation de l'objet de l'invention est représentée, à titre d'exemple non limitatif, au follows. An embodiment of the object of the invention is shown, by way of nonlimiting example, at
dessin annexé.attached drawing.
La figure unique montre une coupe longitudinale The single figure shows a longitudinal section
du raccord.of the fitting.
Comme indiqué sur la figure, le raccord selon l'invention permet de relier l'extrémité d'un tuyau 1 à une douille ou attache filetée 2 d'un appareil, d'un tuyau etc. As shown in the figure, the connector according to the invention makes it possible to connect the end of a pipe 1 to a socket or threaded fastener 2 of an appliance, a pipe etc.
Le raccord est constitué par un embout fileté- The connector consists of a threaded end
3 pouvant se visser par une extrémité sur l'attache filetée 2, pouvant être serré, par sa partie 4, sur des faces planes et portant à son extrémité opposée un anneau 5 présentant la surface conique 6 dont le plus petit diamètre est placé vers la partie extérieure du raccord. Avantageusement, l'anneau 5 est relié à l'extrémité de l'embout 3 au moyen d'un filetage 7 à 3 can be screwed at one end to the threaded fastener 2, which can be tightened, by its part 4, on flat faces and carrying at its opposite end a ring 5 having the conical surface 6, the smallest diameter of which is placed towards the outer part of the fitting. Advantageously, the ring 5 is connected to the end of the end piece 3 by means of a thread 7 to
pas à gauche, opposé à celui du filetage de l'attache 2. not to the left, opposite that of the thread of fastener 2.
Entre la surface conique 6 de l'anneau 5 et la surface conique 8 de l'attache 2 est inséré un corps d'étanchéité 9, partiellement en coupe sur la figure, à l'intérieur duquel est inséré le tuyau 1. Le corps Between the conical surface 6 of the ring 5 and the conical surface 8 of the fastener 2 is inserted a sealing body 9, partially in section in the figure, inside which is inserted the pipe 1. The body
d'étanchéité 9 est composé d'une âme métallique inté- seal 9 is composed of an integrated metal core
rieure 10 qui présente à l'extrémité tournée vers l'at- 10 which presents at the end turned towards the
tache 2 le resserrement 11 ayant un plus petit diamètre que le tuyau 1, et à l'extrémité opposée, la partie évasée 12. Cette partie 12 présente une surface conique spot 2 the constriction 11 having a smaller diameter than the pipe 1, and at the opposite end, the flared part 12. This part 12 has a conical surface
13 ayant une inclinaison opposée à la surface 6. 13 having an inclination opposite to the surface 6.
De l'âme 10 est solidaire, dans le corps 9, la partie extérieure 14 en matière élastomère qui présente une zone d'épaisseur plus grande 15 en contact avec Of the core 10 is integral, in the body 9, the outer part 14 of elastomeric material which has an area of greater thickness 15 in contact with
la surface conique 8 de l'attache 2 et une partie termi- the conical surface 8 of the fastener 2 and a finished part
nale 16 comprise entre les surfaces 6 et 13.- nale 16 between surfaces 6 and 13.-
Sur la paroi intérieure 17 de cette partie termi- On the inner wall 17 of this termi-
nale 16 sont réalisés plusieurs reliefs annulaires 18 conçus pour faciliter l'étanchéité entre le corps 9 nale 16 are made several annular reliefs 18 designed to facilitate sealing between the body 9
et le tuyau 1. Cette étanchéité se réalise par le ser- and the pipe 1. This sealing is carried out by the
rage de l'embout 3 sur l'attache filetée 2, comprimant axialement le corps 9, de manière à serrer la zone 15 contre la surface 8, obtenant donc l'étanchéité entre le corps 9 et l'attache 2, déterminant en outre, par suite de l'action des surfaces 6 et 13 sur la partie 16 pendant ce serrage, une déformation de la partie 16 en direction radiale, la serrant donc fortement contre la surface extérieure du tuyau 1 et obtenant donc rage of the end piece 3 on the threaded fastener 2, axially compressing the body 9, so as to tighten the zone 15 against the surface 8, thus obtaining the seal between the body 9 and the fastener 2, further determining, as a result of the action of the surfaces 6 and 13 on the part 16 during this tightening, a deformation of the part 16 in the radial direction, thus tightening it strongly against the external surface of the pipe 1 and thus obtaining
l'étanchéité entre le tuyau 1 et le corps 9. the seal between the pipe 1 and the body 9.
La réalisation du corps 9 d'une seule pièce avec la partie extérieure 14 en matière élastomère solidaire de l'âme métallique intérieure 10, par exemple obtenue lors du moulage de la partie 14, permet une plus grande rapidité de montage et en outre la partie terminale 16 est empêchée de tourner, lors du serrage, contre la paroi du tuyau 1, évitant donc des dommages à la surface 17 et aux reliefs 18, qui seraient nuisibles The realization of the body 9 in one piece with the outer part 14 of elastomeric material integral with the inner metal core 10, for example obtained during the molding of the part 14, allows greater assembly speed and also the part terminal 16 is prevented from turning, during tightening, against the wall of the pipe 1, thus avoiding damage to the surface 17 and to the reliefs 18, which would be harmful
A l'étanchéité.Sealing.
Sur l'anneau 5 est avantageusement prévue la présence d'un évidement circulaire 19 qui permet une déformation régulière de la partie terminale 16 pendant The ring 5 is advantageously provided with the presence of a circular recess 19 which allows regular deformation of the terminal part 16 during
le serrage de l'embout 3.tightening the nozzle 3.
Pour permettre le montage, on sépare l'anneau du corps de l'embout 3; toutefois, dans le cas o l'attache filetée a un diamètre supérieur au diamètre extérieur du corps d'étanchéité 9, l'embout 3 et l'anneau peuvent être réalisés d'une seule pièce. To allow mounting, the ring is separated from the body of the nozzle 3; however, in the case where the threaded fastener has a diameter greater than the outside diameter of the sealing body 9, the end piece 3 and the ring can be made in one piece.
