DEVICE FOR CONNECTION OF COMMUNICATIONS Russian patent published in 2011 - IPC F16L27/00 

FIELD: machine building.

SUBSTANCE: device consists of case with two coaxial spherical intercommunicated cavities. Spherical connecting pipes with axial channels performing angular transfers relative to lengthwise axis of the case are installed in the spherical cavities. The connecting pipes are constricted in the case with nuts of working spherical surface and a conic cavity expanding towards an external end. Support elements are made in the case; lugs on external surfaces of nuts interact with these elements. The spherical connecting pipes are packed in the case by constricting a rubber element with the nut via a fluoroplastic element.

EFFECT: connection of non-axial joined parts at communication.
