20160115742 | ASSEMBLY FOR PRODUCING A THREADED CONNECTION FOR DRILLING AND OPERATING HYDROCARBON WELLS, AND RESULTING THREADED CONNECTION - An assembly for producing a threaded connection includes first and second tubular components with an axis of revolution and each provided at one end with at least first, second, and third continuous threaded zones provided in succession on the same helix on the outer or inner peripheral surface of the component depending on whether the threaded end is male or female. The components are capable of cooperating together upon makeup. At least one of the first, second, or third threaded zones has a variable width thread profile and is self-locking. The ends respectively finish in a free terminal surface. Each of the ends is free of a specific abutment surface. At least one sealing surface is provided between each of the adjacent threaded zones in order to cooperate in a sealed interference fit with a sealing surface provided on the corresponding end when the connection is made up. | 04-28-2016 |

20080224471 | Male Coupling for Connecting to Female Threaded Coupling - In one embodiment, a male coupling connectable to and separable from a female coupling (e.g., a female threaded port) is provided. The female coupling includes a receiving portion sized to receive at least a portion of the male coupling, where the receiving portion has internal threads provided therein. The male coupling includes a body having a passageway extending therethrough and a locking member disposed about the body and configured to move between locking and releasing positions. The locking member includes a retaining formation configured to engage the internal threads of the female coupling when the locking member is in its locking position. The male coupling further includes a locking sleeve disposed about and axially movable with respect to the body between first and second positions. After insertion of the male coupling into the female coupling and upon movement of the locking sleeve to its first position, the locking sleeve forces the locking member to move to its locking position causing the retaining formation of the locking member to engage the internal threads of the female coupling, thereby locking the male coupling and the female coupling together. | 09-18-2008 |

20130200616 | Threaded connection of high-pressure fluid-carrying components of an injection device for internal combustion engines - In a method for producing a threaded connection between a first component and a second component of an injection device for internal combustion engines, which are each provided for carrying high-pressure fluid, an internal thread is formed on a tubular end portion of the first component, into which the second component can be screwed and clamped against a resting surface of the first component, the second component having formed thereon an external threaded portion for engaging the internal thread of the tubular end portion, an outer ring imparting an elastic prestress acting in the radial direction is pressed onto the tubular end portion, and the components are subsequently screwed together. | 08-08-2013 |
20150300542 | High Pressure Fluidic Connection Assemblies - Fluidic connection assemblies, ports, unions and other components are provided that are well-suited for use in HPLC and UHPLC, as well as in other analytical instrument systems. Such assemblies, ports, unions and components can be biocompatible. | 10-22-2015 |
20160097475 | COMPRESSION COUPLING ASSEMBLY FOR SECURING CONDUITS TOGETHER - A coupling assembly for securing rigid conduits together end-to-end, or to a junction box, includes a coupling body, one or two compressible gland rings, and one or two compression nuts. The coupling body includes a first segment extending from a second segment, with an optional midsection therebetween. The compression nut threadably engages about externally-threaded coupling first and/or second segments, compressing a gland ring as it is tightened. A bend in the compression nut, and complementarily chamfers formed in the coupling body and the gland ring, may help to squeeze and compress the gland ring. The compressible gland ring is internally-threaded, and, when compressed, it bites down or grips unthreaded conduits, and its threads interlock with threads of threaded conduits. Two conduits may be secured together by rotating the coupling body and/or the compression nut of the coupling assembly without needing to rotate conduits, which can be heavy and cumbersome. | 04-07-2016 |
