  • Patent number: 7243686
    Abstract: A hose (10) comprising a tubular body (12) of flexible material arranged between an inner and an outer helically wound wire (22, 24). The hose (10) further comprises an axial strengthening means (20) adapted to reduce deformation of the tubular body (12) when the tubular body (12) is subjected to axial tension, the axial strengthening means (20) being adapted to exert a radially inward force on at least part of the tubular body (12) when axial strengthening means (20) is subjected to axial tension.

  • Publication number: 20070024051
    Abstract: An end fitting (200) for terminating an end of a hose comprising a tubular body of flexible material arranged between inner and outer helical wires, characterised in that the end fitting comprises: an inner member (202) adapted to be disposed at least partially within the hose; and a hose engaging member (208) adapted to press against the inner member 202 to retain the hose between itself and the inner member (202). The end fitting also includes a separate means for retaining one or more layers of the hose, the retaining means comprising an outer retaining member (232) adapted to press against an inner retaining member (230) to retain the or each layer of the hose between the outer and inner retaining members (232, 230) of the retaining means.

  • Publication number: 20060124189
    Abstract: A hose (10) comprising a tubular body (12) of flexible material arranged between an inner and an outer helically wound wire (22, 24). The hose (10) further comprises an elongate member having opposing longitudinal edges, the elongate member being helically wound around the tubular body such that the opposing longitudinal edges of the layer are in an adjacent or overlapping arrangement, wherein each longitudinal edge includes a formation capable of interengaging with a cooperating formation on the opposing longitudinal edge.
