The invention is a sealing assembly for equipment with movable shafts—such as coaxial and side port swivels, hydraulic swivels, and rotary control devices—that prevents the loss of a high pressure fluid through the clearance existing between a housing and the shaft. The invention is disclosed in the context of a coaxial swivel that conducts high pressure fluid from a stationary first conduit to a rotating second conduit that has dynamic runout, and may be misaligned relative to the first conduit.

In an aircraft duct formed with pipes connected in pairs via connectors in which the pipes are mounted with the possibility of axial displacement, there exists a risk that a pipe of the duct, with a dimension greater that the dimension of the nominal pipe, is mounted instead and in place of the latter. In this case, the wrongly mounted pipe would risk not having sufficient clearance in axial translation. In order to solve this problem, it is disclosed to equip one of the relevant connectors with an obstacle limiting the travel of the nominal pipe and preventing the mounting of a pipe with a greater dimension belonging to the duct. A method for assembling an aircraft portion is also proposed, in order to benefit from the particularities of the duct.

A coupling device configured to couple first and second pipes, which comprises a first part coupled to the first pipe and which has a first contact surface, a second part coupled to the second pipe, separate from the first part, and which has a second contact surface configured to collaborate with the first contact surface, at least one clamp comprising at least one clamping jaw comprising a groove, configured to collaborate with the first and second parts, which has a cross section such that a concentric tightening of the clamp causes the first and second contact surfaces to be kept pressed against one another. Thus, the coupling device makes it possible to obtain a ball joint type connection between the first and second pipes.

A cold plate has, on a surface thereof, an attachment surface for contacting a cooling object, and has, in the interior thereof, an accommodating portion that accommodates a cooling medium. The cold plate is provided with a first opening that communicates with the accommodating portion, a body-side connection pipe is connected to the first opening, a tube-side connection pipe, which has a bendable tube connected to one end thereof, is connected to the body-side connection pipe. The body-side connection pipe and the tube-side connection pipe are connected so as to be able to rotate about the pipe axis.

A swivel joint includes a tail section and a body portion that define a passageway therethrough and which can rotate relative to one another. One or more seals and bearings can be disposed between the tail section and the body portion. An electrical conductivity grease fitting can be mounted within a bore hole in the body portion. The electrical conductivity grease fitting can have a lubricant passed therethrough to lubricate the bearings. The electrical conductivity grease fitting has a first portion in electrical communication with the body portion and a second portion that is biased into electrical communication with the tail section to maintain electrical conductivity between the tail section and the body portion.

A siphon elbow for pivotally connecting a first pipe and a second pipe in fluid communication. A first elongated body has a bore extending therethrough and a partially spherical indentation within the bore. A second elongated body has a bore extending therethrough and a generally spherical extension on a first end that pivotally engages the partially spherical indentation of the first elongated body. An internal locking system is disposed in at least one of the bores and locks the second elongated body into an operating configuration in which an angle formed between the first elongated body and the second elongated body is less than 180-degrees. Pivoting of the second elongated body from an installation configuration in which the angle is approximately 180-degrees to the operating configuration activates the internal locking system.

A pipe adapter includes a first tubular element having a first portion and a second portion axially adjacent the first portion defining a socket. A second tubular element has a first portion and a second portion axially adjacent the first portion, the first portion defining a distal end sized for insertion into the socket and having a radially extending stop. An annular sealing member is located between the first portion of the second tubular element and the second portion of the first tubular element and provides an axial seal therebetween. An annular securing member is rotatably disposed around the first portion of the second tubular element and located within and fixed to the socket. The annular securing member contacts the stop to secure the second tubular element axially relative to the first tubular element while also allowing the second tubular element to rotate relative to the first tubular element and annular securing member.

A pipe adapter includes a first tubular element, a second tubular element, and an annular securing member disposed around and fixed to a second portion of the first tubular element. The annular securing member has a flange portion that contacts and secures the second tubular element axially relative to the first tubular element while also allowing the second tubular element to rotate relative to the first tubular element and the annular securing member. An annular sealing member is located around the first portion of the second tubular element to provide an axial seal along the adapter.

A spoolable swivel, methods, and systems for coupling a first and second length of coiled tubing. The spoolable swivel can include an inner tubular element and an outer tubular element. The inner tubular element and the outer tubular element can both have dimpled distal ends and races on their proximal ends, defining one or more annular voids for swivel bearings.

A swivel fitting assembly includes a female body providing a first connection end portion, and a male fitting body providing a second connection end portion. The male body and the female body are operatively coupled together to form a fluid passage between the first and second connection end portions, and are configured to permit relative rotation of the bodies relative to each other. A swivel lock mechanism is provided to rotationally lock or release the male body relative to the female body in response to a fluid pressure level in the fitting. The swivel lock includes a collar that transitions to a lock state and holds the male body when fluid pressure is at or above a predefined level. The collar transitions to a release state to enable relative rotation of the bodies when the pressure is below the predefined level.
