A rotatable joint for flexible pipes is disclosed including two bodies that are rotatable in relation to one another, wherein the pressurised fluid inside the joint generates an axial thrust that would tend to press the two bodies against one another and is balanced by an axial thrust that is almost equal and opposite generated hydraulically by a counterpressure chamber included between the two bodies and between two annular washers arranged between the two bodies and having diameters that are different from one another. |
