Abstract:
An anti-rotational assembly for a union fitting is disclosed having a hexagonal cental portion non movably covering the hexagonal cental portion of a union fitting and having deformable tubular sections sections covering the nuts of the union fitting and which are crimped onto properly compressed nuts on the union fitting to prevent any further rotation of the nuts.
Abstract:
The present invention provides a joint hose slippage prevention apparatus for preventing slippage of a joint hose connecting a suction pipe extending from a compressor and a suction pipe extending from a throttle body. The joint hose slippage prevention apparatus comprises a tension stay that fastens the compressor side and throttle body side, with ends connected to the compressor side and the throttle body side. Consequently, when the compressor side and throttle side almost separate from each other, they are held down by the tensile strength of the tension stay, whereby the relative positional relation between the compressor side and throttle side is maintained. Accordingly, it is possible to prevent the joint hose from slipping off.
Abstract:
A quick-disconnect, the nipple portion of which has a pressure relief path and a coupler portion of which has a safety lock. The nipple portion is provided with a spring-loaded sleeve which covers the relief flow path when not engaged. The sleeve is hand driven against the spring load to expose the flow relief passage. Any pressure in the quick-disconnect is then discharged to atmosphere. The coupler portion incorporates a piston that is pressure activated to block the motion of a disconnecting sleeve. The piston is moved to the unlocked position by a wave spring when the pressure is removed. These features are packaged in a small volume for use in systems where space is limited. The quick-disconnect is designed and fabricated with materials that can withstand a proof pressure of 20,000 PSI. Such capabilities are especially useful in aircraft systems with a supply pressure of up to 5,000 PSI. The pressure relief assures the quick-disconnect can be relieved of any residual pressure up to 5,000 PSI before it is uncoupled and the lock assures that it can not be uncoupled without pressure relief.
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.
Abstract:
The connection according to the invention comprises two elements adapted to be fitted in each other along an axis of fit and no-mistake means borne by the two elements and adapted to pair the two elements by complementarity of shapes. In order to facilitate manipulation of the connection elements to be fitted, and even easily to allow such manipulation by relatively insensitive robots, while simplifying management of the stocks associated with these connection elements, the connection further comprises means for angularly indexing the two elements, borne by the two elements and adapted to position the two elements angularly with respect to each other before the no-mistake means, at least partly connected to the two elements in removable and configurable manner, cooperate together during fit of these elements.

Abstract:
A breakaway safety shut-off valve including a valve housing and a detachable end portion connected thereto by a region of reduced strength. The housing includes an axial passage and the detachable portion includes an annular shoulder positioned adjacent the region of reduced strength. A ball is guidably displaceable along a circumferential surface of the axial passage between an open position and a closed position, with a spring engaged between the valve housing and the ball to urge the ball toward the closed position. An insert having a plurality of arm segments is engaged between the ball and the annular shoulder to initially maintain the ball in the open position. At least partial detachment of the detachable portion along the region of reduced strength causes at least one of the arm segments to disengage the annular shoulder to permit the spring to displace the ball toward the closed position.
Abstract:
There is provided a plug 13 for a fluid pipe connector 11 for connecting fluid pipes to each other or for connecting a fluid pipe to a storage tank or a processing unit. The plug 13 includes a plug portion 6, a fixing portion 78 for sandwiching a flange 87 of a pipe between itself and the end face of the plug portion 61 to fix and support the flange 87, a cylindrical support 80 which is integrally formed with the fixing portion 78 for supporting the pipe 60, and a fixing nut for covering and fixing the plug portion 61 and the fixing portion 78. Between the fixing portion 78 and the remainder of the cylindrical support 80 is provided an engagement surface 79 for a lock lever 52. On the distal end of the plug portion 61, is provided a valve 62 for engaging a valve 20 of a member which is to be connected to the plug 13, to establish a fluid communication. On the outer peripheral surface of the fixing nut 64, a long groove 83 is provided for properly aligning the plug 13. Thus, it is possible to reduce the size and weight of a plug for a fluid pipe connector, and to improve safety.
Abstract:
A fluid transfer device includes a first section and a second section. The first section includes a first flange with a first fastener on an outer diameter of the adapter. The fluid transfer device includes a coupler secured to the second section to rotate independently of the second section and to mate with an end of the first section. The coupler includes a second flange with a second fastener on an outer diameter of the coupler. A support couples to the first and second fasteners of the flanges to secure the first section to the second section and to prevent relative rotation of the flanges.
Abstract:
The problem of securing a connection in a mechanical structure. fluid line, or electrical line, that can not readily be secured by traditional lock-wiring techniques, is solved through a method and apparatus for securing a connection with a commonly available commercial lanyard and a lanyard retainer. The lanyard retainer has an elongated center section adapted for positioning the retainer adjacent the connection, and means at both ends of the retainer for engaging and retaining the lanyard.
