International Classification:

F16L055/00

US Classification:

285 92, 285276, 285321, 285388

Abstract:

A lockwireless, anti-rotation fitting for connection to a connector. The fitting includes a coupler having a series of circumferential engagement portions disposed about an outer peripheral surface, and a nut receivable coaxially over the outer peripheral surface of the coupler, and which is threadably engageable with the connector. The nut also has a series of complementary circumferential engagement portions disposed about at an inner peripheral surface. With the nut being received coaxially over the first outer peripheral surface of the coupler, the nut is threadably engageable with the connector urging the coupler into a sealing engagement with a sealing surface of the connector, and with the coupler being engaged with the connector sealing surface, the first and second engagement portions are interengaged to delimit the rotation of the nut relative to the connector.

Abstract:

A lockwireless, anti-rotation fitting for connection to a connector. The fitting includes a coupler having a series of circumferential engagement portions disposed about an outer peripheral surface, and a nut receivable coaxially over the outer peripheral surface of the coupler, and which is threadably engageable with the connector. The nut has an opening through which is received the end of a locking mechanism. The locking mechanism end is interferingly engageable with the coupler engagement portions such that with the nut being received coaxially over the coupler outer peripheral surface of the coupler, the nut is threadably engageable with the connector urging the coupler into a sealing engagement with a sealing surface of the connector, and with the coupler being so engaged, the locking mechanism end is interferingly engaged with at least one of the coupler engagement portions delimiting the rotation of the nut relative to the connector.

Filed:

Jul 21, 1988

Appl. No.:

7/222039

Inventors:

Gerrard N. Vyse - Bedford TX

Assignee:

Stratoflex, Inc. - Fort Worth TX

International Classification:

F16L 3722

US Classification:

285318

Abstract:

A coupling comprising an outer socket or receptacle part having an internal opening, and a nipple or insert part which is sized to be inserted into the opening of the receptacle part. The receptacle and insert parts are provided with outer and inner lock ring grooves, respectively, which are substantially aligned in the radial direction when the parts are assembled. A garter spring is located in and extends between the two grooves when the parts are assembled in order to lock the parts together. The groove of one of the two parts has an arcuate surface and the radius of the surface is substantially the same as the radius of the coils of the spring, whereby the arcuate surface supports the coils and retards flattening of the coils. The groove of the other of the two parts has a surface which overlies the spring and holds the spring in place in the grooves even if the spring should break.

Appl. No.:

5/869661

Inventors:

Gerrard N. Vyse - Bedford TX
Horise M. Cooke - Weatherford TX

Assignee:

Stratoflex, Inc. - Fort Worth TX

International Classification:

G01M 1900

US Classification:

73168

Abstract:

This disclosure deals with apparatus for and a method of testing a plurality of hydraulic and/or pneumatic systems. Each such system has a hose connected in it and the hose terminates in a valved fitting. All of the fittings are releasably attached to a subassembly which in turn is attached to center member or a manifold. When the systems are to be tested, a test fixture is attached to the center member, such attachment automatically opening the valved fittings. The test fixture also includes valved fittings identical with those connected in the systems. All of the fittings are opened by attachment of the test fixture, and the appropriate tests are then carried out. When the systems are not being tested, the test fixture is removed and a protective cover is applied to the center member in place of the fixture.

Appl. No.:

5/869464

Inventors:

Gerrard N. Vyse - Bedford TX
Horise M. Cooke - Weatherford TX

Assignee:

Stratoflex, Inc. - Fort Worth TX

International Classification:

F16L 3500

US Classification:

29407

Abstract:

This disclosure deals with apparatus and method for simultaneously making a plurality of connections between different pneumatic or hydraulic systems, or between parts of each systems, and for testing such systems. The systems, or parts thereof, include groups of hose fittings, and the apparatus includes two or more sub-assemblies and a central connecting member. Each sub-assembly is releasably attached to the fittings of a group, and all of the sub-assemblies are then secured to the central connecting member to form a complete assembly. The central connecting member has a plurality of fluid passages formed therein which interconnect the fittings, thus forming fluid connections between the systems or parts thereof. The passages in the connecting member may also be arranged to interconnect fittings of a single group. Each sub-assembly may be separately used to test the system, or part thereof, associated with the fittings attached to it.

Gerrard N. Vyse - Bedford TX

Assignee:

Stratoflex, Inc. - Fort Worth TX

International Classification:

F16L 3722

US Classification:

285 81

Abstract:

This disclosure relates to a releasable quick-connect fitting, comprising an insert having an annular lock groove and an annular release groove in the outer periphery thereof, the release groove having a smaller diameter than the lock groove. A receptacle has a bore for receiving the insert and an annular bore groove is formed in the bore. An annular retainer is mounted in one of the lock and release grooves and movable to the other of the grooves. The insert is movable to a lock position in the receptacle wherein the lock and bore grooves are substantially in radial alignment and the retainer extends into said lock and bore grooves, and movable to a release position in the receptacle wherein the release and bore grooves are substantially in radial alignment and the retainer extends into the release groove. A stop is removably connected to one of the insert and receptacle and engageable with the other, the stop preventing movement of the insert to the release position but enabling movement to the release position when removed.

Assignee:

Stratoflex, Inc. - Fort Worth TX

International Classification:

F16L 1300
F16L 3320

US Classification:

285174

Abstract:

This disclosure relates to apparatus for making fluid flow connections. The apparatus comprises a tubular metal member having first and second ends. The first end is mechanically formed to the shape of one part of a two part quick-connect coupling, the one part being integrally formed on the first end of the member. The second end is mechanically formed to the shape of another fitting part which is also integral with the member. The portion of the member between the two ends is shaped to follow a desired path in order to interconnect other components. The one part of the quick-connect coupling preferably forms a tubular receptacle having an annular internal groove, a snap ring in the groove, and a relatively viscous fluid at least partially filling the groove around the ring. The disclosure also relates to a method of making and assembling apparatus as described.
