Specifically, the modular joint has a pair of sealing assemblies interconnected by a tubular sealing member which permits angular misalignment, axial movement and rotational movement between conduits. Each of the sealing assemblies includes a tubular housing with a replaceable sealing sleeve which is positively retained therein by a split retaining ring. Typically, the housings are welded to conduits, and thus, can only be removed by cutting them from their respective conduits. However, the housings are provided with access openings for inserting a camming tool therein to remove the sealing sleeves without cutting the housings away from their respective conduits. Therefore, in refurbishing the modular joint, the housings are reusable, while the sealing sleeves and tubular sealing members are replaceable.

  • Patent number: 4900070
    Abstract: A coupling assembly for connecting adjacent ends of conduits, primarily used for aircraft fuel lines having redundant locking features is provided. This coupling can be manipulated with one hand and includes laterally spaced locking tines which engage raised elements for locking the coupling in secured relationship. The coupling assembly can be manipulated with one hand and has viewing ports to be sure that all parts are in place. Also, the tines and guide members are configured to create a force between the two with a longitudinal component tending to open the assembly.

  • Patent number: 4807913
    Abstract: A junction adapted to transport fluid between hot and cold bodies is disclosed. The bodies include an inlet or an outlet having a mechanism to attach the junction. The attachment mechanisms include a retaining portion and a sealing portion. The junction includes a sleeve having an overall cylindrical tubular shape with two ends. Inwardly projecting peripheral flanges are positioned on each of the sleeve ends. Seals, adapted to be received by the sealing portion of the attachment members seal the sleeve with the body inlet and outlet. The sleeve peripheral flanges are adapted to be mechanically received by the attachment retaining portions such that the flanges contact the retaining portions along a peripheral line to minimize the heat transfer from the sleeve between the two bodies.

  • Patent number: 4699403
    Abstract: Fully integrated self-contained connectors for standard tubes include a first annular member having an axial bore preferably of a continuously hollow-cylindrical configuration for receiving ferrules of those standard tubes. A locking arrangement peripheral of the first annular member carries locking members extending through openings in that first annular member for retaining a ferrule at a tube retention shoulder in a locking position. At least one further annular member is axially slidable on the first annular member and houses the locking arrangement outside that first annular member. The locking members are actuated to a locking position upon axial sliding of the further annular member in one direction. Conversely, the locking members are actuated to a release position upon axial sliding movement of the further annular member in another direction. The further annular member may define one or more internal ramps for that purpose.

  • Patent number: 4643464
    Abstract: The invention relates to a device for connecting two pipe ends, having a socket, a spigot and an annular seal therebetween. These parts are clamped together by flanges of a clamp in order to close the device. While prior art sockets and spigots have been made of massive material and shaped by expensive machining processes, the invention provides the spigot which is formed as a generally U-shaped profiled ring having a front and a rear annular flange and holding the sealing element between the flanges. The outside diameter of the front flange is smaller than that of the rear flange. The socket may also be a profiled ring in order to further reduce the manufacturing costs.

  • Patent number: 4613170
    Abstract: An adaptor for connecting tubular members in an exhaust system. The adaptor comprises a tube having opposite ends that are curled outwardly in a generally circular configuration. The curled ends of the adaptor are press fitted within the ends of the tubular members of the exhaust system and each curled end is disposed adjacent an internal shoulder in the respective tubular member. Exhaust gases passing through the adaptor will heat the adaptor causing it to expand axially to bring the curled ends into firm contact with the respective shoulders, and the outer surfaces of the curled ends will flatten against the walls of the respective tubular members to provide a tight seal between the adaptor and the tubular members.

  • Patent number: 4606559
    Abstract: A sleeve connector for connecting the ends of two tubes together, in particular socket tubes, comprises a socket formed with or connected to one of the tubes. The socket has an inner annular recess which is bounded by a conical surface which tapers radially inwardly toward an end of the socket. A retaining collar is secured around the spigot end of another tube to be connected to the first mentioned tube. At least one locking member is disposed around the spigot and is positioned in the annular recess so that it can bear against the conical surface. The locking member has an inner cylindrical contact surface which engages on the spigot and an outer contact surface which has a sectional toroidal shape wherein all normals to the toroidal shape pass through the cylindrical contact surface.

  • Patent number: 4436326
    Abstract: The object of the invention is to provide a coupling for fluid conveying ducts which has built in capability to allow for radial and/or angular misalignment of the ducts which it is coupling and also retain axial flexibility. Such coupling includes a pair of interconnectable coupling half assemblies each with eccentric openings (17) for passage of one of the tube ends (10) therethrough with their associated ends in spaced relation. These coupling half assemblies also may include abutting faces disposed in a plane (P) oblique to their longitudinal centerline (C). Relative adjustment of the eccentric openings (17) provides radial adjustment of the tubes (10) while relative adjustment of the coupling half assembly faces along the plane (P) provides angular adjustment of the tubes (10). Any combination of axial, radial, and/or angular misalignment of the tubes (10) within the dimensional envelope of the coupling can be accommodated by manipulation of the parts relative to each other.
