ABSTRACT:
A fluid swivel joint coupling has a body member, a first connecting member and a second connecting member. The body member includes an inlet portal, and outlet portal and a diverted fluid passageway connecting them. The first connecting member is pivotably mounted in flow communication with one of the portals for rotation about a first swivel axis, and the second connecting member is pivotably connected in flow communication with the other portal for rotation about a second swivel axis. The second connecting member has a diverted fluid passageway opening onto a third portal, a longitudinal axis extending through the third portal and a portion of the passageway. The first connecting member is operatively connected to a rigid conduit while the second connecting member is operatively connected at the third portal to a flexible conduit. The axes are disposed such that the longitudinal axis is never in the plane which passes through the first swivel axis parallel to the second swivel axis, so that the longitudinal axis may align itself with the direction of any flexible force applied through the flexible conduit. The body member and the second connecting member may have interlocking elements which cooperatively couple, and which uncouple when a tensile force above a predetermined limit is interposed between the flexible conduit and the rigid conduit.
