Abstract:
1. Flexible hose with knitted reinforcement, comprising at least one inner tubular layer made of polymer material defining a longitudinal axis and at least one knitted reinforcement layer wound on said inner layer, said reinforcement layer comprising at least one first and one second series of yarns spiral wound on said inner layer and knitted together to form respective mesh courses inclined with respect to said axis and respective mesh wales substantially parallel to said axis, in which each of said meshes is formed by a portion of a yarn of said first series forming a first chain eyelet and by a portion of a yarn of said second series forming a second chain eyelet and in which each of said first and second chain eyelets is substantially U-shaped with an open end and a closed end and with a pair of longitudinal sections spaced from one another at said open end and joined by a substantially transverse section at said closed end, wherein for each of said meshes, said first chain eyelet and said second chain eyelet are substantially identical to each other and have the respective substantially longitudinal sections and substantially transverse sections completely substantially reciprocally superimposed to define a reinforcement knitting that is generally single-layer and locally of double-yarn type.
