Abstract
Description
L'invention concerne les tuyaux souples en caoutchouc de forme coudé utiliss en automobile, dans les circuits de refroidissement des moteurs ou de climatisation de l'habitacle. Ces tuyaux sont destinés à raccorder de façon souple des organes du véhicule, mobiles l'un par rapport à l'autre et qui présentent le plus souvent des portions de tubulures rigides à axes sécantes La souplesse du tuyau est destines à absorber les vibrations et mouvements relatifs des organes raccordés et à faciliter le montage sur les tubulures rigides désalignées. The invention relates to flexible rubber hoses of bent shape used in cars, in the cooling circuits of engines or air conditioning in the passenger compartment. These pipes are intended to flexibly connect vehicle members, which are movable relative to one another and which most often have portions of rigid tubing with intersecting axes. The flexibility of the pipe is intended to absorb vibrations and movements. relative to the connected members and to facilitate mounting on the misaligned rigid pipes.
Les véhicules neufs sont généralement équipes à l'ori- gine de tels tuyaux fabriques par moulage avec des formes coudées et sinueuses pour contourne les organes interposes entre les deux tubulures à raccorder et ces formes coudées varient avec chaque mode le de véhicule. New vehicles are generally fitted at the origin of such pipes manufactured by molding with bent and sinuous shapes for bypassing the bodies interposed between the two pipes to be connected and these bent shapes vary with each vehicle mode.
L'orsqu1il s'agit, sur un véhicule en service, de remplacer un tuyau endommagé il est généralement nécessaire de se procurer un tuyau coudé exactement semblable au tuyau d!ori- gine,ce qui impose aux accessoiristes d'avoir en stock une grande variété de tuyaux de diverses formes. When it is a question of replacing a damaged pipe on a vehicle in service, it is generally necessary to obtain a bent pipe exactly similar to the original pipe, which requires accessoryists to have a large stock variety of pipes of various shapes.
L'invention propose un genre de tuyau souple destiné principalement au marché de remplacement des tuyaux coudés d'origine et qui soit susceptible de prendre au moment du montage diverses conformations coudées ou sinueuses conve- nant pour une diversité de modèles d'automobiles de sorte que le commerçant accessoiriste peut, à partir des très petit nombre de tuyaux de ce genre, répondra aux divers besoins du remplacement, ce qui lui permet de reduire considérablement le stock nécessaire. The invention proposes a kind of flexible pipe intended mainly for the replacement market of original bent pipes and which is capable of taking at the time of assembly various bent or sinuous conformations suitable for a variety of automobile models so that the accessory merchant can, from very few pipes of this kind, meet the various replacement needs, which allows him to considerably reduce the stock required.
Suivant invention ce genre de tuyau souple se présen- te au repos sous une forme générale sensiblement rectiligne, éventuellement enroulable en couronnes, et il est caractérisé en ce qu'il présente une succession de courtes parties cylindriques droites ' reliées les unes aux autres par de courtes parties à paroi ondulée plus souples en flexion formant des zones de coudage localisées, ce qui permet lors du montage de couder l'ensemble du tuyau sans cassure et réduction de section pour procéder au raccordez ments des tubulures par emmanchement des parties cylindri ques droites sur les dites tubulures. According to the invention, this type of flexible hose is present at rest in a generally substantially straight form, possibly windable in crowns, and it is characterized in that it has a succession of short straight cylindrical parts' connected to each other by short parts with corrugated wall more flexible in bending forming localized bending zones, which allows during assembly to bend the whole of the pipe without breaking and reduction of section to proceed to the connections of the pipes by fitting the straight cylindrical parts on the said tubes.
Les parties cylindriques successives formant manchettes d'emmanchement sur les tubulures rigides des organes à raccorder peuvent pro sont or toutes le meme diamètre ou, alter- nativement ces parties cylindriques peuvent présenter des diamètres difforonts de façon à pouvoir s'adapter sur des tubulures de diamètres variant d1un modèle de véhicule à un autre. The successive cylindrical parts forming fitting sleeves on the rigid pipes of the members to be connected may be all of the same diameter or, alternatively, these cylindrical parts may have different diameters so as to be able to adapt to pipes of diameters varying from one vehicle model to another.
De préférence les parties cylindriques droites et les parties ondules sont arrange os en modules identiques se répétant sur toute la longueur du tuyau, chaque module ne comprenant pas plus de 4 parties cylindriques droites et ne pro sentant pas une longueur L supérieure à 5 fois le diamètre du tuyau. Preferably the straight cylindrical parts and the wavy parts are arranged in identical modules repeating over the entire length of the pipe, each module comprising no more than 4 straight cylindrical parts and not having a length L greater than 5 times the diameter. of the pipe.
Quelques exemples de réalisation de l'invention sont décrits ci-après en référence au dessin ci-joint où des tuyaux sont illustres schématiquement en coupe longitudinale sur les fig. 1 à 5. Some embodiments of the invention are described below with reference to the attached drawing where the pipes are illustrated diagrammatically in longitudinal section in FIGS. 1 to 5.
Dans une forme de réalisation simplifiée illustrée sur la fig. 1 le tuyau souple est réalise en caoutchouc, éventuellement avec une armature de renforcement en tissu ou en tricot noyée dans sa paroi, et il se pro sente sous la forme générale d'une longueur droite indéfinie qui peut être stockée à ltétat enroulé en couronne et dans laquelle on peut découper des portions de tuyaux de la longueur voulue pour procéder au remplacement d'un tuyau coudé d'origine, par exemple un tuyau de radiateur ou de circuit d'air do climatisation. In a simplified embodiment illustrated in FIG. 1 the flexible hose is made of rubber, possibly with a reinforcement of fabric or knitted fabric embedded in its wall, and it takes the general form of an indefinite straight length which can be stored in the state wound in a crown and in which portions of pipes can be cut to the desired length in order to replace an original bent pipe, for example a radiator or air conditioning pipe.
Le tuyau présente de courtes parties cylindriques droites successives 1 présentant une longueur axiale 1 de tordre do 0,5 à 2,5 fois leur-diamètre D et ces parties cylindriques 1 sont reliées les unes aux autres par de courtes parties à paroi ondulée 2 de longueur axiale lllift comprises entre environ 0,3 à 2,5 fois le diamètre D, ces parties 2 pouvant présenter par exemple de t à 5 ondulations.The pipe has short successive straight cylindrical parts 1 having an axial length 1 of twisting from 0.5 to 2.5 times their diameter D and these cylindrical parts 1 are connected to each other by short parts with corrugated wall 2 of axial length lllift of between approximately 0.3 to 2.5 times the diameter D, these parts 2 possibly having, for example, from t to 5 undulations.
Les parties cylindriques t et les parties ondulées 2 sont do préférence arrangées en modules identiques de longueur L se répétant sur toute la longueur du tuyau. The cylindrical parts t and the corrugated parts 2 are preferably arranged in identical modules of length L repeating over the entire length of the pipe.
On peut cependant avoir sur la longueur du tuyau certaines portions cylindriques 1 de longueur lllii différentes des autres et certaines portions ondulées 2 de longueur 11 différentes des autres de sorte que l'on obtienne des modules successifs ayant plusieurs parties 1 et plusieurs parties 2.One can however have over the length of the pipe certain cylindrical portions 1 of length lllii different from the others and certain corrugated portions 2 of length 11 different from the others so that one obtains successive modules having several parts 1 and several parts 2.
Mais dans ce cas les modules successifs ne groupent pas plus de 4 parties cylindriques et ils présentent de préférence une longueur axiale L qui ncexcède pas 5 fois le diamètre D du tuyau, cela afin de conserver une plus grande aptitude d'adaptation à la plupart des modèles de véhicules.But in this case the successive modules do not group more than 4 cylindrical parts and they preferably have an axial length L which does not exceed 5 times the diameter D of the pipe, this in order to maintain a greater adaptability to most of the vehicle models.
Dans le cas de la fig.2 les parties droites successives présentent des diamètres différents D1 et D2 afin de former des manchettes susceptibles d'être raccordées à des tubulures de diamètre correspondant. Compte tenu de la souplesse de la paroi du tuyau, cette différence de diamètre entre D1 et D2 est de préférence comprise entre 1 et 3 fois l'épaisseur e de la paroi du tuyau. Là encore les parties droites 1 et les parties ondulées 2 sont arrangées on modules successifs identiques de longueur L. In the case of fig.2 the successive straight parts have different diameters D1 and D2 in order to form cuffs capable of being connected to pipes of corresponding diameter. Given the flexibility of the wall of the pipe, this difference in diameter between D1 and D2 is preferably between 1 and 3 times the thickness e of the wall of the pipe. Here again the straight parts 1 and the corrugated parts 2 are arranged in identical successive modules of length L.
Dans le cas de la fig.3 le tuyau présente une longueur définie avec à une extrémité une courte partie cylindrique 1 et à l'autre extrémité deux courtes parties cylindriques rapprochées la et lb reliées par une courte portion ondulée 2 et la partie restante du tuyau présente une paroi unifor mément ondulée 3. Ce tuyau de longueur définie peut être utilisé tel quel ou il peut au besoin être raccourci en sectionnant la partie terminale au droit de la ligne 4. Le même tuyau peut former le module d'une longueur indéfinie de tuyau présentant une succession de modules identiques. In the case of fig.3 the pipe has a defined length with at one end a short cylindrical part 1 and at the other end two short cylindrical parts close together la and lb connected by a short corrugated portion 2 and the remaining part of the pipe has a uniformly wavy wall 3. This pipe of defined length can be used as it is or it can be shortened if necessary by cutting the terminal part to the right of line 4. The same pipe can form the module with an indefinite length of pipe presenting a succession of identical modules.
La fig.4 montre un tuyau semblable à celui de la fig. 3 mais dans lequel la partie terminale cylindrique la présente un diamètre différent de la partie cylindrique voisine lb. Fig. 4 shows a pipe similar to that of fig. 3 but in which the cylindrical end part has a different diameter from the neighboring cylindrical part 1b.
L'autre extrémité du tuyau peut être formée de la même manière.The other end of the pipe can be formed in the same way.
La fig.5 montre encore une autre réalisation découlant do celle de la fig.2 mais dans laquelle il est prévu de courtes parties cylindriques adjacentes 1c et Ad de diamètres différents D3 et D4. Ces couples de parties cylindriques lc et 1d sont reliés à d'autres parties cylindriques de plus petits diamètre D1 par de courtes parties ondulées 2, llensemble formant une succession de modules identiques~ de longueur L1 dans laquelle on peut sectionner des lons gueurs variables de tuyau pour obtenir des tuyaux de reua- placement susceptibles de s'adapter à une grande variété de modèles de véhicules. Fig.5 shows yet another embodiment arising from that of Fig.2 but in which there are provided adjacent short cylindrical parts 1c and Ad of different diameters D3 and D4. These pairs of cylindrical parts lc and 1d are connected to other cylindrical parts of smaller diameter D1 by short corrugated parts 2, the whole forming a succession of identical modules ~ of length L1 in which it is possible to cut variable lengths of pipe to obtain replacement hoses that can be adapted to a wide variety of vehicle models.
