  • Patent number: 8079619
    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, characterized 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.

  • Patent number: 7743792
    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.

  • Patent number: 7735524
    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.

  • Patent number: 7712792
    Abstract: An end fitting for terminating an end of a hose including a tubular body of flexible material arranged between inner and outer gripping members, wherein the end fitting includes: an inner member adapted to be disposed at least partially within the hose; a sealing member adapted to seal at least part of the tubular body fully around the circumference between the sealing member and the inner member; and a separate load transfer member adapted to transfer axial loads between the hose and the inner member in such a manner that said axial loads are diverted around the sealing member in order to reduce, or eliminate, the axial load on the hose between the sealing member and the inner member, and wherein the sealing member is adapted to seal against the tubular body independently of the application of axial loads between the hose and the inner member.
