Title (EN) FLEXIBLE TUBE COMPRISING A VARIABLE STIFFNESS BELLOWS
(FR) TUYAU FLEXIBLE COMPORTANT DES SOUFFLETS A RIGIDITE VARIABLE
Abstract: front page image
(EN)This invention relates to a flexible tube (51) that includes a bellows having a plurality of convolutes (55) formed in the wall of said tube (51) and extending above the outer surface (52) of the tube (51), said convolutes being spaced from one another in the axial direction of the tube (51), wherein at least one of said convolutes (55) comprises two opposing bending sections (57) and two restrained elongation sections (59) positioned between the bending sections (57), and wherein the height of the bending sections (57) above the outer surface (52) of the tube (51) is greater that the height of the restrained elongation (59) sections above the outer surface (52) of the tube (51).
(FR)La présente invention concerne un tuyau flexible (51) comportant des soufflets pourvu d'une pluralité d'ondulations (55) formées sur la paroi du tuyau (51) et s'étendant au-dessus de sa surface externe (52). Ces convolutions sont espacées dans le sens axial du tuyau (51). Au moins l'une de ces convolutions (55) comprend deux parties (57) de flexion opposées et deux parties (59) d'allongement limité placées entre les parties (57) de flexion. La hauteur des parties (57) de flexion au-dessus de la surface externe (52) du tuyau (51) est plus importante que la hauteur des parties (59) d'allongement limité au-dessus de la surface externe (52) du tube (51).
