Title (EN) HOSE
(FR) TUYAU SOUPLE
Abstract: front page image
(EN)A hose comprising an internal supporting tube (1) and an external protecting envelope (2) both made of an elastic material, at least two pairs (3) and (4) of reinforcing layers (5), (6) and (7), (8) embedded between them and laid on each other and an interlayer (10) made of a non-metallic fabric placed directly onto the surface of the supporting tube (1) and serving for even distribution of stresses arising between the supporting tube (1) and the pairs (3) and (4) of the reinforcing layers (5), (6) and (7), (8) during the exploitation of the hose. Each of the reinforcing layers (5), (6) and (7), (8) is designed as a family of spirally wound interparallel cords (9), whereas each pair (3) and (4) of the reinforcing layers (5), (6) and (7), (8) is designed as a pair of families of symmetrically wound cords (9). The angle of helix of the cords (9) of the lower pair (3) of the reinforcing layers (5) and (6) in relation to the hose geometrical axis is more than the angle of helix of the cords (9) of the upper pair (4) of the reinforcing cords (7) and (8).
(FR)Un tuyau souple comprenant un tuyau interne de support (1) et une enveloppe de protection externe (2) les deux etant fabriques en materiau elastique, au moins deux paires (3) et (4) de couches de renforcement (5), (6) et (7), (8) disposees entre les deux et placees l"une sur l"autre et une couche intermediaire (10) en un tissu non metallique placee directement sur la surface du tuyau (1) de support et servant a repartir les contraintes resultantes entre le tuyau de support et les paires (3) et (4) des couches de renforcement (5), (6) et (7), (8) pendant l"utilisation du tuyau. Chacune des couches de renforcement (5), (6) et (7), (8) est concue comme famille de cordes inter-paralleles enroulees en spirale (9) tandis que chaque paire (3) et (4) des couches de renforcement (5), (6) et (7), (8) est concue comme paire de familles de cordes enroulees symetriquement. L"angle de l"helice des cordes (9) de la paire inferieure (3) des couches de renforcement (5) et (6) par rapport a l"axe theorique du tuyau est plus eleve que l"angle de l"helice des cordes de la paire superieure (4) des cordes de renforcement (7) et (8).
