Fluid management systems for handling pressurized fluid connect various subsystems or subunits without the need to use reinforced tubing. The system utilizes one or more segments of unreinforced conduit that are encapsulated at various points along a length of the segment with one or more rigid encapsulating members. The unreinforced conduit may be made a disposable element while the rigid encapsulating members may be re-used. In one aspect, the encapsulating member may include a two-part valve body that surrounds and encapsulates a portion of the unreinforced conduit. In another aspect, the encapsulating member may include a two-part jacket that surrounds and encapsulates a portion of the unreinforced conduit. The two-part valve bodies and two-part jackets may be joined at various points within the system as part of the overall flow system.

The valve interconnector further comprises abase cap (8) secured to the neck, a valve assembly (5) secured to the base cap, the valve assembly being configured to assume at least a closed position and at least an open position. The valve interconnector further comprises a sealing ring (3) configured to provide a leakproof connection between the valve interconnector and the receiver interconnector. The valve interconnector further comprises a code ring cap (9), wherein the code ring cap (9) further comprises a head portion (99) covering at least a portion of the external surface of the head portion (89) of the base cap (8), the head portion (99) of the code ring cap (9) comprising a sealing ring enclosing portion (91) configured to cooperate in retaining the sealing ring (3) within the sealing ring seat (2).

Some fluid coupling devices described herein are configured for use in fluid systems for purposes of providing a single-use, aseptic disconnection functionality that substantially prevents fluid spillage when being disconnected. In some embodiments, the coupling portions cannot be reconnected to each other after being disconnected from each other.

A locking fitting assembly that can be removably installed in a tapped hole on a housing and resists unintended loosening of the fitting assembly. The fitting assembly maybe installed at a mounting location for receiving the fitting assembly, and includes abase with engagement structure configured to engage corresponding structure adjacent the mounting location to secure the base against rotation. The fitting assembly further includes a nipple fitting received on the base and having first and second oppositely disposed coupling features. The first coupling feature is configured to mate with a complementary coupling feature of the housing, such as the tapped hole, whereby the nipple fitting can be sealingly secured to the housing. Locking structure disposed between the base and the nipple fitting is configured to resist relative rotation between the base and the nipple fitting.

A coupling assembly (10) is reconfigurable among three states. In a disconnected state, a spring-biased lock indicator (20) is in a first lock indicator position, and the lock indicator includes a restriction member (40) that in the first lock indicator position retains an actuator in a first actuator position such that a valve is in a closed position and a locking pin is in a retracted position. In a connected/valve-closed state, the lock indicator (20) is in a second lock indicator position in which the restriction member (40) permits movement of the actuator (30), but with the actuator (30) still being in the first actuator position such that the valve is in the closed position and the locking pin (46) is in the retracted position. In a connected/valve-open state, the lock indicator (20) is in the second lock indicator position to permit movement of the actuator (30), and now with the actuator (30) being in the second actuator position such that the valve is in the open position and the locking pin (46) is in an extended position to lock a second coupling assembly to the coupling assembly to form a unisex coupling connection.

Methods and apparatus are disclosed for a coupling nozzle for cryogenic fluid. An example nozzle includes a flow body defining a conduit. The flow body is configured to permit cryogenic fluid to flow through the conduit. The nozzle includes a mounting ring through which the flow body slidably extends and a bushing fixedly positioned adjacent the mounting ring. The bushing slidably receives the flow body in a keyed manner to prevent rotation of the flow body. The nozzle includes a flow control assembly at least partially disposed in the conduit of the flow body. The flow control assembly is configured to permit the cryogenic fluid to flow through the flow body in an open position and prevent the cryogenic fluid from flowing through the flow body in a closed position.

A fluid connector in a fluid joint assembly such as in a machine hydraulic system includes a connector body having a stem with a seal face extending circumferentially around a connector axis at a backup sealing location. A non-metallic seal is upon the stem and extends circumferentially around the connector axis at a primary sealing location. The fluid connector also includes a swivel nut including threads and a snap retainer and supported for rotation upon the stem. The fluid connector can establish a primary sealing state by way of hand installation, and can be torqued to a backup sealing state to provide a robust metal-to-metal seal.

A coupling system having an inner tube, a collar, a circular gasket concentrically disposed between the inner tube and the collar; a pair of CAM levers structurally engageable with the collar, and a handle connecting the pair of CAM levers such that a user can single-handedly move the handle between the locked position and the unlocked position.

The invention is based on a tensioning clamp (10) with a tensioning band (12), two tensioning elements (14a, 14b), a pulling element (16) and an insert (18), wherein the tensioning band (12) comprises two ends which are each folded over to form a loop. Each of the loops (20a, 20b) receives a tensioning element and has openings (24, 26). The pulling element (16) connects the tensioning elements (14a, 14b) through the openings (24, 26) of the loops (20a, 20b) and transmits a pulling force applied to tension the tensioning clamp (10). The insert (18) is arranged in a circumferential region of the loops (20a, 20b) between the tensioning band (12) and a binding material, and has a profile with at least two radially inwardly projecting ribs (30a, 30b) extending in the circumferential direction of the tensioning band (10) and a trough (32) formed between the ribs (30a, 30b). A rear side of the insert (18) facing the tensioning belt (12) in the region of the trough (32) forms a support surface (34) for the setting material.

It is proposed that the support surface (34) has at least one recess (40a, 40b) in a circumferential region lying below the tensioning elements (14a, 14b).

A plug-in coupling for connecting a first double-walled vacuum-insulated cryogenic line to a second. The plug-in coupling has a coupling plug and a coupling socket. The coupling plug can be plugged into the coupling socket, these being retained in a plugged-together state by fixing means. A guide column is arranged on the coupling plug or the coupling socket. The guide column has arranged on it elastic means which, in the assembled state of the plug-in coupling, are subjected to stressing and which subject the coupling plug and/or coupling socket to an elastic force which strives to release the coupling plug and coupling socket from one another as soon as the fixing means no longer hold the coupling plug and coupling socket together. The elastic energy stored in the elastic means ensures that, in the event of an emergency, the coupling plug and coupling socket are quickly released from one another.
