Abstract

The threaded spigot fitting (2,3) mounts the end of an internally reinforced (11) rubber hose (1), comprising a spigoted steel sleeve (2) with a prestressed brass bore liner (3), and using an axial screw effect with elastic radial wedging. The axial extremities of the sleeve (2) incorporate extensive bore and barrel rebates respectively, its max. and min. diameters corresp. to the hose barrel and bore diameters. The barrel rebate forms a threaded spigot (8), the bore rebate (4) being threaded (5) to screw onto a stripped hose end. The reduction in bore diameter may be provided by a double radial step (6,7) providing radial and axial stops for the liner (3). The latter is initially cranked (8) to obtain the elastic radial wedging effect.

Description

l'invention concerne les tuyaux souples à paroi en ca- outchouc renforcée par une armature interne, et leurs moyens de raccordement. the invention relates to flexible pipes with rubber wall reinforced by an internal reinforcement, and their connection means.

Il est déjà connu de réaliser la liaison entre un tuyau et un raccord (appropriée à la technique utilisée):
- soit par vissage d'un. raccord dans ou sur le tuyau.It is already known to make the connection between a pipe and a fitting (suitable for the technique used):
- either by screwing a. fitting in or on the pipe.

Pour la mise en oeuvre de cette technique, le raccord peut compren- dre un embout inséré à force dans l'alésage du tuyau et une bague extérieure vissant à la fois sur cet embout et sur l'armature (préalablement mise à nu) du tuyau.For the implementation of this technique, the connector can comprise a nozzle inserted by force into the bore of the pipe and an outer ring screwing both on this nozzle and on the reinforcement (previously exposed) of the pipe. .

- soit par sertissage, sur le tuyau, de la jupe extérieu- re d'un raccord1 dont la jupe intérieure est insérée et retenue dans ledit tuyau. - Or by crimping, on the pipe, the outer skirt of a fitting 1, the inner skirt of which is inserted and retained in said pipe.

- ou encore par dudgeonnage d'une bague déformable insérée dans le tuyau et constituant l'un des éléments du raccord, dont l'aw;re est constitué par un embout coiffant le tuyau, la ddforma- tion de la bague emprisoenant le tuyau, prealablement dénudés entre la bague et l'embout. - or again by expanding a deformable ring inserted into the pipe and constituting one of the elements of the fitting, the aw; re of which is constituted by an end cap covering the pipe, the deformation of the ring trapping the pipe, previously stripped between the ring and the end piece.

les deux premières techniques ne permettent pas d'obtenir une bonne tenue du raccord lorsque le fluide circulant dans le tuyau est à pression élevée. the first two techniques do not allow good fitting behavior to be obtained when the fluid flowing in the pipe is at high pressure.

la troisième technique, utilisee dans 11 invention, ne permettait toutefois pas jusqu'à present,de réaliser des liaisons tuyau-raccord ne débordant à la fois, ni hors de la périphérie du tuyau, ni dans l'alésage de celui-ci, double inconvénient ressenti
- lorsque les tuyaux ont à traverser des orifices, ceux- ci devant alors être au diamètre des raccords et non à celui des tuyaux,
- dans la circulation du fluide achemine.the third technique, used in the invention, has not, however, hitherto made it possible to produce pipe-fitting connections which do not overlap either outside the periphery of the pipe or in the bore thereof, double perceived inconvenience
- when the pipes have to pass through orifices, these must then be the diameter of the fittings and not that of the pipes,
- in the circulation of the conveyed fluid.

la présente invention a notamment pour but de pallier les inconvénients précédents des modes de liaisons connus tuyauraccords. the object of the present invention is in particular to alleviate the preceding drawbacks of the known modes of connection between pipes and fittings.

Elle concerne à cet effet un tuyau souple, à paroi en caoutchouc renforcée par une armature interne, dont une extrémité au moins est pourvue d'un raccord comprenant, dune part un embout pourvu d'une jupe recevant intérieurement l'extrémité dénudée du tuyau et prolongée axialement par des moyens de raccordement et, d'autre part, une bague intérieure, engagée dans le tuyau et dilatée mécaniquement de façon telle que ladite partie dénudée du tuyau soit serrée entre ladite bague et ladite jupe de l'embout du raccord, caractérisé en ce que : l'embout du raccord présente un diamètre extérieur maximal sensiblement égal au diamètre extérieur du corps du tuyau et, au droit des moyens de raccordement, un diamètre minimal non inférieur au diamètre intérieur du corps du tuyau, avec un épaulement interne situé entre la jupe de l'embout et les moyens de raccordement, - la bague intérieure présente une forme cylindrique à paroi mince et lisse d'un diamètre intérieur non in férieur au diamètre intérieur du corps du tuyau, ladite bague étant appuyée radialement sur une portée de l'embout et axialement contre l'épaulement interne de eelui-ci. To this end, it relates to a flexible hose, with a rubber wall reinforced by an internal reinforcement, at least one end of which is provided with a connector comprising, on the one hand, a nozzle provided with a skirt receiving internally the stripped end of the hose and extended axially by connection means and, on the other hand, an inner ring, engaged in the pipe and mechanically expanded so that said stripped part of the pipe is clamped between said ring and said skirt of the connector end piece, characterized in that: the fitting end piece has a maximum outside diameter substantially equal to the outside diameter of the pipe body and, in line with the connection means, a minimum diameter not less than the inside diameter of the pipe body, with an internal shoulder situated between the skirt of the endpiece and the connection means, - the inner ring has a cylindrical shape with a thin and smooth wall with an inside diameter not less than the inside diameter eur of the pipe body, said ring being supported radially on a bearing surface of the nozzle and axially against the internal shoulder thereof.

Dans ce tuyau de l'invention, la liaison tuyau proprement dit-raccord tient remarquablement aux hautes pressions (notamment à 50 bars) tant sur le plan meeanlquet du fat de 11 ancrage du tuyau et plus particulièrement de son armature sur; la jupe de l##mbout, que sur le plan hydraulique, les jonctions tuyau-raccord étant parfaitement étanches et aucun relieS ne subsistant dans l'alésage. De plus, la situation et la non-déformation de l'embout permettent de conserver à celui-ci toutes les qualités initiales du métal consti tutif.  In this pipe of the invention, the actual pipe-fitting connection is remarkably due to the high pressures (in particular at 50 bars) both on the meeanlquet plane of the fat of the pipe anchoring and more particularly of its reinforcement on; the skirt of the ## mbout, only hydraulically, the pipe-fitting junctions being perfectly watertight and no connections remaining in the bore. In addition, the location and the non-deformation of the tip allow it to retain all the initial qualities of the constituent metal.

La continuité du diamètre extrérieur rend le tuyau de l'invention particulièrement approprié à son utilisation comme tuyau dilatable, et notamment, en tant que tel, dans les cannes d'injection. The continuity of the outer diameter makes the pipe of the invention particularly suitable for its use as an expandable pipe, and in particular, as such, in the injection pipes.

Pour réaliser l'ancrage du tuyau sur l'embout, la face interne de la jupe de l'embout est avantageusement pourvue de parties en creux, dans lesquelles une partie du tuyau est repoussée lors de la déformation de la bague. Ces parties en creux peuvent être avantageusement réalisées sous forme de cannelures transversales ou d'une cannelure helicordale d'axe confondu avec l'axe lon gitudînal du raccord, Suivant l'invention, on peut avantageusement réaliser l'embout en acier et la bague intérieure en laiton. De préférence l'épaisseur de cette bague est sensiblement constante (sauf à une extrémité chanfreinée) permettant une déformation linéaire parfaite lors de sa dilatation mécanique (dudgeonnage). To achieve the anchoring of the pipe on the end piece, the internal face of the skirt of the end piece is advantageously provided with hollow parts, in which a part of the pipe is pushed back during the deformation of the ring. These hollow parts can advantageously be made in the form of transverse grooves or a helical groove with an axis coincident with the longitudinal axis of the connector. According to the invention, it is advantageous to make the steel end piece and the inner ring. Brass. Preferably the thickness of this ring is substantially constant (except at a chamfered end) allowing perfect linear deformation during its mechanical expansion (expansion).

Un exemple de réalisation du tuyau de l'invention est décrit ci-après, en référence au dessin ci-joint dans lequel
- la figure 1 est une demi-vue de face en coupe, du tuyau de l'invention terminé0
- la figure 2 est une demi-vue de face, en coupe, de l'embout du tuyau de la figure lo
- la figure 5 est une demi-vue de face, en coupe, de la bague intérieure du tuyau de la figure 1 dans son état initial, avant déformation0
le tuyau de l'invention 1, tel que montré sur la figure 1 comprend essentiellement un raccord constitué par un embout 2 et une bague intérieure cylindrique 3 l'embout 2 comporte une jupe 4, entre laquelle et la bague 3 est emprisonnée l'extrémité 5 du tuyau proprement dit, et des moyens de raccordement usuels, ici un filetage mtlee
le diamètre extérieur maxieal de embout est sensiblement égal au diamètre extérieur du corps du tuyau.An example embodiment of the pipe of the invention is described below, with reference to the attached drawing in which
- Figure 1 is a half front view in section, of the hose of the invention finished0
- Figure 2 is a half front view, in section, of the end of the hose of Figure lo
- Figure 5 is a half front view, in section, of the inner ring of the pipe of Figure 1 in its initial state, before deformation0
the pipe of the invention 1, as shown in FIG. 1 essentially comprises a connector constituted by an end piece 2 and a cylindrical inner ring 3 the end piece 2 comprises a skirt 4, between which and the ring 3 is trapped the end 5 of the pipe itself, and the usual connection means, here a thread mtlee
the maximum outside diameter of the nozzle is substantially equal to the outside diameter of the pipe body.

Au droit des moyens de raccordement, son diamètre minimal est au moins égal au diamètre intérieur du corps du tuyau. In line with the connection means, its minimum diameter is at least equal to the inside diameter of the pipe body.

le diamètre intérieur de la bague 3 (dans son état final de la figure 1) est au moins égal au diamètre intérieur du corps du tuyau. the inside diameter of the ring 3 (in its final state in FIG. 1) is at least equal to the inside diameter of the body of the pipe.

Comme montré sur la figure 2, l'embout est pourvu d'une portée 6 et d'un épaulement 7, sur lesquels l'extrémité correspondante de la bague intérieure 3 est calée respectivement, radialement et axialement0 la bague 3 présente initialement, comme montré sur la figure 3, un épanouissement 8 coopérant avec la portée 6 et l'épaulement 7 pour réaliser le double calage précédent, Le diamètre de la portée 6 présente un diamètre supérieur au diamètre minimal de l'embout 2 de la valeur de l'épaisseur de la bague 3o
La face intérieure de la jupe 4 est pourvue d'une cannelure hélicoïdale 9 dans les filets de laquelle s'ancre llextrémie té 5 du tuyau, lors de la délormation de la bague 3 (figol)o
la bague intérieure 5 présente une épaisseur constante sauf au voisinage de son extrémité opposée à l'épanouissement 8, qui est pourvue d'un chanfrein extérieur 10, permettant de faciliter notamment le glissement de l'extrémité de la bague 3 le 'org du tuyau, lors de la déformation de ladite barye 30
Pour passer ::
- d'une position initiale (non représentée), dans laquel- le la bague 3 (fig.3) est logée dans l'embout 2 (fig.2), son épa- nouissegnent 8 étant calé sur ledit embout 2 par coopération avec la portée 5 et l'épaulement 7, et l'extrémité 5 du tuyau inséré entre lesdits embout et bague après avoir été dénudé sur sa face extérieure jusqu'à l'armature,
- à la position finale représentée sur la figure 1, on provoque mécaniquement la dilatation de la bague 3, ce qui entraîne la compression de la paroi du tuyau 5.As shown in Figure 2, the tip is provided with a bearing 6 and a shoulder 7, on which the corresponding end of the inner ring 3 is wedged respectively, radially and axially 0 the ring 3 initially present, as shown in FIG. 3, a development 8 cooperating with the bearing surface 6 and the shoulder 7 to carry out the preceding double wedging, The diameter of the bearing surface 6 has a diameter greater than the minimum diameter of the end piece 2 by the value of the thickness of the 3o ring
The inner face of the skirt 4 is provided with a helical groove 9 in the threads of which the t-outlet 5 of the pipe is anchored during the formation of the ring 3 (figol) o
the inner ring 5 has a constant thickness except in the vicinity of its end opposite to the opening 8, which is provided with an outer chamfer 10, making it possible in particular to facilitate the sliding of the end of the ring 3 the 'org of the pipe , during the deformation of said barye 30
To pass ::
- From an initial position (not shown), in which the ring 3 (fig.3) is housed in the end piece 2 (fig.2), its blade 8 being wedged on said end piece 2 by cooperation with the surface 5 and the shoulder 7, and the end 5 of the pipe inserted between said end piece and ring after having been stripped on its outer face up to the frame,
- in the final position shown in FIG. 1, the ring 3 is mechanically caused to expand, which causes the wall of the pipe 5 to be compressed.

lors de la dilatation de la bague 3, par dudgeonnage, là bague calée sur la portée 6 et l'épaulement 7 se déforme dans le sens longitudinal, sa progression étant facilitée par la présence du chanfrein 10. En m#me temps la paroi 5 du tuyau est comprimée entre la bague 3 et la jupe 4 de l'embout, les cables de l'armature 11 coopérant avec les filets de la cannelure 9 pour réaliser un ancrage du tuyau sur l'embout 2. during the expansion of the ring 3, by expansion, the ring wedged on the bearing 6 and the shoulder 7 is deformed in the longitudinal direction, its progression being facilitated by the presence of the chamfer 10. At the same time the wall 5 of the pipe is compressed between the ring 3 and the skirt 4 of the end piece, the cables of the armature 11 cooperating with the threads of the groove 9 to anchor the pipe on the end piece 2.

l'embout 2, lui, demeure dimensionnellement stable, puisqu'il n'est soumis à aucune déformation. the end piece 2 itself remains dimensionally stable, since it is not subjected to any deformation.

l'embout 2 et la bague 3 peuvent être réalisés, le premier en acier, notamment en XC 35 et la seconde en laiton. the end piece 2 and the ring 3 can be produced, the first in steel, in particular in XC 35 and the second in brass.

Bien entendu, l'invention n'est pas limitée au mode de réalisation décrit et représenté. Of course, the invention is not limited to the embodiment described and shown.

Elle est susceptible de nombreuses variantes accessibles à l'homme de l'art, suivant les applications envisagées et sans s'écarter du cadre de l'invention. It is susceptible of numerous variants accessible to those skilled in the art, depending on the applications envisaged and without departing from the scope of the invention.
