<p>A joint-type coaxial connection is disclosed, of the so-called rapid type, wherein the two fluids passing in the respective two pairs of pipes flow coaxial with respect to each other, respectively one external and one internal, substantially coaxial to the axis of the joint. The two fluids can circulate in the same direction or in opposite directions, which is substantially irrelevant to the correct functioning of the joint-type connection.</p> |
