A joint structure connecting a first and second double pipe, includes a male bayonet at an end portion of one of the pipes, the male bayonet including a first flange; a female bayonet at an end portion of the other of the pipes, the female bayonet including a second flange fastened to the first; a first positioning member mounted on the first double pipe; a second positioning member mounted on the second double pipe, the second positioning member being positioned with respect to the first so that a center axis of the male bayonet and the female bayonet conform to each other; and a slide mechanism which supports the first positioning member so the first positioning member is slidable in an axial direction of the first double pipe or supports the second positioning member so the second positioning member is slidable in an axial direction of the second double pipe.

A multi-coupler of a work vehicle includes a first portion and a cover. The first portion has a coupling surface. The first hydraulic connector is arranged on the coupling surface. The cover is movable between a first position in which the cover covers the coupling surface and a second position in which the coupling surface is uncovered by cover. The cover has a cover shell defining an interior cavity. The cover also includes an insert received into the interior cavity of the cover shell. The insert is operable to absorb a fluid that escapes from the first hydraulic connector.

A rotary multiport greasing valve having an outer sleeve and an inner sleeve within the outer sleeve. The outer sleeve has at least one inlet port and at least 2 outlet ports. The inner sleeve has an inlet port, a central passageway, and an outlet port. The inner sleeves inlet port is fluidly connected to the outer sleeve's inlet port. The inner sleeve rotates within the outer sleeve so that the inner sleeves outlet port is circumferentially aligned with a selected outer sleeve outlet port creating a fluid pathway from the outer sleeve inlet port into the inner sleeve's inlet port through the central passageway through the inner sleeves outlet port and finally through the outer sleeves outlet port to create an open flowpath. In the instance where a closed flowpath is desired the inner sleeve inlet port is rotated so as not to align with any portion of an outlet sleeve outlet port.

The invention relates to an umbilical termination assembly for terminating a cable or umbilical. The termination assembly comprises a plurality of umbilical elements extending from an umbilical and which pass through a bulkhead plate. The seated ball element has a spherical body through which an umbilical element passes. The ball element is seated in a cup member which allows the ball element to rotate through a large range of angles allowing it to be aligned with the umbilical element without the umbilical element needing to be manipulated or forced into position. The umbilical element can then be attached to the ball element which is supported by the cup member on the bulkhead. This allows the axial tension in the umbilical element to be transferred to the bulkhead.

A decompression heat-insulating pipe structure that can exhibit the desired heat-insulating performance and is easy to assemble. In the structure, a space between ends of inner and outer tubes is decompressed. The outer tube includes a first flange, which extends radially inward from an axially one end thereof, and a second flange, which extends radially outward from the axially other end thereof. The inner tube includes a third flange, which extends radially inward from an axially one end thereof and is opposed to the first flange at an axially inward position of the first flange, and a fourth flange, which extends radially outward from the axially other end thereof and being opposed to the second flange at an axially outward position of the second flange. First and second elastic seal members are disposed between the first and third flanges and between the second and fourth flanges, respectively.

A swivel joint for a construction machine can detect a slewing angle of an upper slewing body and has a high maintainability. The swivel joint includes a body, a stem, a lower cover, and a sensor unit. The sensor unit includes: a rotation angle sensor fixedly attached to an upper end of the stem; and a rod having a distal end provided with a detection target to be detected by the rotation angle sensor and a proximal end fastened to the lower cover. The stem is formed with: a rod insertion hole for receiving the rod to be inserted therethrough; and a stem-side drain oil passage for allowing a drain oil to pass therethrough.
