CA 2376520

The present invention relates to a medium-carrying hose, preferably for pressure medium and for use in, for instance, an engine unit, the wall of the hose comprising at least one wall portion (5). The wall portion (5) is connected with at least one expansion portion (4) to form a continuous hose casing, so that the circumference of the hose is variable between a minimum value, when the expansion portion (4) is unexpanded, and a maximum value, when the expansion portion (4) is maximally expanded. The expansion portion (4) extends in the transverse and the longitudinal direction of the hose, the wall portions (5) being displaced relative to each other both in the transverse and in the longitudinal direction of the hose as the circumference increases and the expansion portion (4) expands. The invention also relates to a method for manufacturing such a hose.

La présente invention concerne un flexible de transfert de fluide, de préférence un fluide pressurisé tel qu'un fluide pour moteur, la paroi du fluide comprenant au moins un élément de paroi (5). L'élément de paroi (5) est connecté à au moins un élément d'expansion (4) de façon à former une enceinte de flexible continue, de façon que la circonférence du flexible soit variable entre une valeur minimale, lorsque l'élément d'expansion (4) n'est pas en expansion, et une valeur minimale, lorsque l'élément d'expansion est en expansion maximale. L'élément d'expansion (4) se déploie dans le sens transversal et dans le sens longitudinal du flexible, les éléments de paroi (5) se déplaçant relativement l'un à l'autre aussi bien dans le sens transversal que dans le sens longitudinal du flexible au fur et à mesure que la circonférence augments et que l'élément d'expansion (4) se déploie. L'invention concerne également un procédé de fabrication d'un tel flexible.
