摘要： An open-ended coupler for joining a pipe to a larger opening defines a passageway having straight and angled sections. The straight section has a uniform inner diameter concentric about a centerline sized to receive the outer diameter of the pipe. The angled section has a narrow end with an inner diameter less than that of a wide end and of the straight section, and being at least as large as the inner diameter of the pipe. The angled section has an upper portion above the centerline that at least in part increases in radius from the narrow end to the wide end. A lower portion has a constant radius, at least along a line extending between the narrow and wide ends at a six o'clock position with respect to the open end of the angled section. A face groove holds an o-ring and an alignment tab fixes the rotational orientation of the coupler.

摘要： 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.

摘要： A sleeve-type pipe joint 10 comprising a joint body 11 having a cylindrical projection 12 adapted to be inserted into a pipe 40 to be connected; a ring member 20 having a larger inner diameter than an outer diameter of the pipe 40; and a resiliently deformable, cylindrical sleeve member 30 moved into a space between the ring member 20 and the pipe 40, at least one of an inner surface of the ring member 20 and an outer surface of the sleeve member 30 being provided with a tapered portion, such that when the sleeve member 30 is moved into the ring member 20, the sleeve member 30 is deformed inward, resulting in tight connection of the inner surface of the pipe 40 to the outer surface of the cylindrical projection 12. When the ring member 20, the sleeve member 30, and the joint body 11 are assembled, the ring member 20 and the sleeve member 30 resist detachment from the assembled pipe joint 10.

A plug connection is provided between a corrugated hose (1) and an unprofiled pipe (31), a holding element (3, 34, 50) that surrounds the unprofiled pipe (31) being connected at least indirectly with the hose end (4), and the end (31) of the unprofiled pipe being surrounded by a sealing ring (16, 17, 30) that is situated before the holding element (3, 34, 50). The sealing ring is connected at least indirectly with the hose (1) so as to form a seal. It is provided that the holding element (3, 34, 50) is situated in the hose end (4) and is held thereby, at least indirectly, by mutual positively locking engagement in the axial direction, and that on the other side of the seal (17, 18, 30) a guide sleeve (18, 25) having an inner diameter that corresponds to the outer diameter of the unprofiled pipe (31) is situated before the holding element (3, 34, 50). The sleeve is held radially by the hose (1) practically play-free, and at least indirectly, by mutual positively locking engagement in the axial direction.

摘要： A fluid coupling includes various features. One feature is a disconnect tool that may expand a lock ring from engagement with a lock shoulder to permit the male half and female half to be separated. Another feature is to utilize geometry and structure whereby a leak would occur to indicate the condition of wear within the coupling while the coupling halves remain mechanically coupled. A further feature is to provide connection verification structure to assure that a complete connection of the male and female halves has been made. A still further feature is to provide an anti-rotational sleeve which would selectively prevent and permit relative rotation between the male half and the female half.

摘要： A tube fitting for a tube end has a female threaded member that cooperates with a male threaded member. The female member includes a tube gripping device in the form of a gripping ring or ferrule that is attached to the female member by a fungible web. Upon a partial pull-up the female engages a camming surface on the male threaded member and breaks off or separates from the female threaded member to become a separate piece so that the fitting then functions as a single ferrule tube fitting. Additional features include a steep camming angle on the camming surface to cause the ferrule to grip the tube end with a bite-type action and to form a primary seal between the camming surface and a front end of the separated ferrule. The ferrule front end, and optionally the entire female threaded member including the initially integral tube gripping device, are hardened to be at least about 3.3 times harder than the material of the tube end.
