| A positive swivel fitting provides for a system flow transmitting portion and a separate lock-down portion. The flow transmitting portion is configured to be receivable within the lock-down portion. When the flow transmitting portion is properly and “positively” positioned, then the lock-down portion can be secured and the position of the flow transmitting portion is maintained, thus making alignment with other parts of the flow device variable. The fitting can be used within any air, other gas or liquid flow system. | ||||||
| 82 | Fluid coupling assembly having a rotatable coupling | US11746928 | 2007-05-10 | US07988201B2 | 2011-08-02 | Grant M. Randle |
| A fluid coupling assembly includes a rotatable fluid coupling and fastener, and a gasket having upper and lower washers interconnected by a deflectable strap. When the strap is laterally deflected, the fastener passes through openings in the coupling with minimal interference. The strap exerts a return force for engaging the washers with the fastener upon release. Tangs on the washers engage the fastener, and one washer forms a seal against a surface. A banjo joint assembly includes a rotatable banjo coupling, the gasket, a gasket with tangs, and a bolt retained to the coupling by the tangs. A method for preparing a fluid coupling assembly for attachment to an external surface includes providing a gasket with deflectable portions, positioning a fluid coupling in the space therebetween, deflecting the portions sufficiently to insert a fastener into the coupling, and retaining the coupling on the fastener when the portions are not deflecting. | ||||||

The contact seals may be metal-to-metal seals, or alternatively may include a resin polymer element. For connecting a tube directly in the port, one embodiment of the invention includes an outwardly extending lip on an expanded portion of the tube and a tube nut rim wherein the tube nut engages the expanded portion and by tightening the tube nut, the tube lip deforms on the tapered port and the tube nut rim deforms on both the tapered port and the tube. Another embodiment of the invention provides a fluid coupling for a tube which is transverse to the port, allowing for flow redirection in the coupling similar to the flow redirection in prior art "banjo" couplings. The body of the transverse coupling includes a lip which deforms on the tapered surface of the port, and the body also includes a tapered surface on which a rim of the bolt contacts, thereby providing a contact seal at both potential leak points. Optionally, o-rings may be added to provide additional seals. Both embodiments may be designed not to seal without the application of tool generated torques. | ||||||

| 100 | Test in place valve and valve fitting | US218725 | 1980-12-22 | US4384591A | 1983-05-24 | Richard M. Tan |
| A test in place poppet valve and fitting assembly having a minimal air volume internal configuration is provided for attaching a portable hydraulic test system to a snubber internal hydraulic line. The valve fitting includes structure for connection to the test system. After the valve fitting has been attached to the poppet valve, but before the poppet valve has been opened, a passageway and the interior of the poppet valve are evacuated and filled with hydraulic fluid. A remotely actuated, spring biased probe extends from the fitting through the passageway to engage a poppet for selectively opening the poppet valve. When actuated to an open position, a prong on the probe is inserted into a cavity, and the poppet is supported on the probe. Using the poppet valve and valve fitting, the test system may be attached to a snubber internal hydraulic line 12 without introducing an appreciable amount of air. | ||||||
