ABSTRACT:
A fluid swivel joint coupling has first and second body members pivotably connected together for pivoting about a swivel axis. The first body member includes an inlet portal, an outlet portal, a diverted fluid passageway opening into the outlet portal and a channel communicating the inlet portal with the diverted passageway. The second body member is pivotably mounted in flow communication with the outlet portal and has a second diverted passageway communicating through a second channel to a third portal. Each channel has an axis of elongation offset from the swivel axis so that fluid may enter the diverted passageway in the first body member tangentially from the first channel and flow therethrough in vortex fashion along the swivel axis into the second diverted passageway and leave the second diverted passageway tangentially to flow out the second channel. The body members may have interlocking elements which cooperatively couple, and which uncouple when a tensile force above a predetermined limit is interposed between the inlet portal and the third portal, and in that case the diverted passageways have volute configuration about valving which shuts flow through the body members when they uncouple. The fluid thus flows in a one revolution spiral to the first diverted passageway and from the second diverted passageway.
