  • Publication number: 20120146325
    Abstract: A hydraulic duct for feeding fluid at high pressure includes a rigid tube and a flexible hose connected to the rigid tube by a connecting assembly. The connecting assembly includes an endform in communication with the rigid tube over which the flexible hose extends. The endform includes a primary annular projection extending outwardly from a periphery of the endform and at least one auxiliary annular projection extending outwardly from the periphery of the endform. The primary annular projection includes a leading edge, a trailing edge, a landing region that extends axially from the trailing edge toward the leading edge and a stop bead that extends outwardly from the leading edge beyond the landing region. A clamping component is compressed over the flexible hose.

  • Patent number: 7870655
    Abstract: A method for endforming a tubular member for use assembly for a hydraulic system comprises (1) a connector member having an inner surface exhibiting a stepped configuration and a fixing member at the distal end thereof, and (2) an endform tubular member having an outer surface corresponding to the inner surface of the connector member, wherein the endform tubular member mates with inner surface of the connector member to provide an endform tubular assembly having an improved design for conveying fluids in a hydraulic system. The endform tubular assembly has inherent features therein that are measured to provide quantified values for assessing the robustness of the assembly and predict the performance of such assembly in high pressure applications for prolonged periods of time.

  • Patent number: 7819222
    Abstract: A device for attenuating energy along a conduit, comprising a first member having an essentially semi-cylindrical outer surface and a first cavity extending substantially longitudinally from end to end. A second member having an essentially semi-cylindrical outer surface is provided, with the outer radii of the first and second members being the same. The second member also has a longitudinally extending cavity. When the two members are secured to one another to form the device, the two cavities face one another to form a bore that extends from end to end and has respective opposed tapered portions having a circular cross-sectional configuration that decreases in diameter inwardly. The bore also has a central, cylindrical portion disposed between the tapered portions and having an axial length that is no greater than one third of the overall axial length of the device.

  • Patent number: 7717135
    Abstract: An energy attenuation device for a system adapted to convey pressurized fluid through tubing of the system, comprising a multi-part conduit section for receiving fluid from, and returning fluid to, the tubing, the conduit section including a central portion, two intermediate portions respectively disposed at opposite ends of the central portion, and two end portions respectively disposed at an end of an intermediate portion remote from the central portion. The central portion has at least one aperture in a peripheral surface and a first diameter that is less than a second diameter of the intermediate portions. The end portions have a third diameter that is less than the second diameter. The end portions are received at least partially in the tubing sections. A hose section is disposed about the central portion and at least part of each intermediate portion.
