  • Patent number: 7226088
    Abstract: A banjo fitting is disclosed comprising a block, a stud, a saddle washer pair and a cap. The saddle washer pair is bent so as to partially surround and clip onto the block. In this manner the block and washer pair form a single unit to simplify installation of the banjo fitting. The block further includes a pair of walls that extend from opposite faces of the block and engage the stud so as to provide a clocking feature. In this manner, the stud and the block remain properly aligned even as the cap is tightened on the stud to secure the block.

  • Patent number: 7036850
    Abstract: A coupling to connect pipe, including lengths of pipe, valves, hoses, and pipe and hose fittings, includes a body to closely receive the end portion of the pipe to be coupled. A set of first class lever jaw members each having a power arm and a weight arm are mounted to the coupling body to establish a fulcrum for rotation of each lever jaw member about the fulcrum between an engaged position and a disengaged position with respect to the pipe end portion when received in the coupling body. The weight arms may include a gripping surface such as a rubber or plastic material or gripping teeth to grip a smooth end portion of a pipe, or the end portion of the pipe may include a shoulder, such as formed by a groove in the end portion, so the weight arms engage the shoulder to secure the pipe in the coupling.

  • Patent number: 7000952
    Abstract: A coupling apparatus and method for coupling two duct sections together to form a joint therebetween. The apparatus includes a catcher ring component formed coextensive with the edge of one section of duct, and a catcher finger component formed coextensive with an edge of the other section of duct being coupled to form the joint. The catcher finger component includes a catcher finger which is longitudinally aligned with a flange of the catcher ring, and that protrudes inwardly into its associated section of duct. In the event of a failure of a main clamping assembly disposed over an outer periphery of the two duct sections at the joint, the catcher finger and flange engage to limit separation of the two sections of duct to only a controlled, limited degree. This protects other subassemblies and components positioned closely adjacent the duct from any damage that might result from separation of the two duct sections, including exposure to high temperature and pressurized air.

  • Patent number: 6974162
    Abstract: A coupling assembly for plastic pipes including a nut, a body, a grip-ring, and a seal. The nut can engage the body through appropriate threads and includes a hooked projection having a sloping surface adapted to abut against and provide a force on a corresponding surface of the grip ring within the body. A pipe is inserted through the nut, grip-ring, and seal into the body. Tightening of the nut causes its sloped surface to engage and the grip ring to be forced both radially and longitudinally. Radial compression results in the grip-ring engaging the pipe whilst longitudinal forcing causes it to be forced into the body simultaneously abutting against and compressing the seal whilst dragging the pipe further into the body. The nut and the body may further have tapered surfaces that are brought together as the grip-ring is forced into the body. The physical connection between the body and the nut provides reinforcing for the nut, a feature especially useful when dealing with soft plastics.

  • Patent number: 6971685
    Abstract: An expandable threaded connection between segments of expandable tubulars that provides multiple sealing points along the pin and box members that can withstand high pressure is disclosed. The present invention utilizes a gap that is created between the pin nose and the back of the box member when the threaded connection is made up and a reverse trapping angle machined into the pin nose end and the back of the box. The radial expansion of the tubulars causes axial movement of the pin nose and the box member until the pin nose is in contact with the back of the box member, thereby closing the gap and forcing the pin nose into sealing engagement with the back of the box member. The reverse trapping angle forces the nose of the pin member outwardly (i.e., toward the outer diameter of the expandable tubular string) as it is forced into contact with the back of the box member during the expansion process.

  • Patent number: 6969094
    Abstract: A tube coupling for the detachable coupling of tube line sections of a high-pressure tubing system. The tube coupling includes two coupling blocks held together by a clamping screw, whereby one of the coupling blocks has a coupling plug that engages a plug socket provided on the other coupling block. A sealing ring is formed of a plastically deformable material and is enclosed between a front face of the coupling plug and a bottom-side sealing surface of the plug socket. In order to protect the sealing ring from being lost, damages and/or contaminated during assembly or opening and dosing the coupling, in a preassembled condition it is enclosed within a protective socket. To homogeneously load the sealing ring, the sealing ring is located at one point of a supporting triangle, the two other supporting points of being formed by a pair of supporting surfaces arranged side by side at an outer end of side flanges of the coupling blocks.
