摘要:
A seamless convoluted hose assembly. The assembly includes: a tubular inner liner having an outer surface, an inner surface, and an inner liner wall therebetween which defines a passageway. The assembly further includes a helical coil or a plurality of annular loops which produce convolutions in the outer surface of the tubular liner when the tubular inner liner is forced through the helical coil or plurality of loops under heat and pressure.

The object of the present invention is to provide a gasket forming mold with a structure in which curling of the reversing section of the gasket molding does not occur easily. To achieve said object, the forming mold for integrally forming an endless shaped gasket has forming grooves as cavities in the parting surfaces of the forming mold and the forming grooves have a reversing section in a part thereof. The reversing section has two linear portions and the ends of the two linear portions are connected by an arc-shaped curved section. The two linear portions are arranged at literally-symmetrical positions and are arranged so that a distance therebetween is enlarged little by little from one end toward the other. The ends where said distance is enlarged are connected by the circular arc-shaped curved section.

L'invention a trait à un procédé de fabrication d'un carter composite de compresseur basse pression de turbomachine axiale. Le carter comprend une paroi circulaire et une bride de fixation formant avec la paroi une arête vive. Le procédé comprend les étapes de : fourniture (100) d'un moule avec un coin configuré pour former l'arête du carter ; mise en place (106) d'un profilé en résine thermoplastique chargée le long du coin ; mise en place (107) d'un renfort fibreux dans le moule en épousant le profilé ; fermeture (108) du moule d'injection ; polymérisation (109) d'une résine injectée dans le moule ; démoulage (110) du carter. L'invention a trait également à un carter composite avec une paroi annulaire et une bride à une extrémité de la paroi en formant une arête vive à l'intérieur du carter. Le carter est renforcé par une préforme fibreuse, l'arête est renforcée à l'aide de fibres courtes de longueur moyenne inférieure à 5,00mm.
