    • A rotatable joint (1) for flexible pipes is disclosed comprising two bodies (3; 7) 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 (15) comprised between the two bodies and between two annular washers (13; 14) arranged between the two bodies and having diameters (Dl; D2) that are different from one another.
    • 公开了一种用于柔性管的可旋转接头(1),其包括可相对于彼此旋转的两个本体(3; 7),其中,所述接头内部的加压流体产生轴向推力,所述轴向推力将倾向于将两个体彼此压靠 并且通过由两个主体之间的反压室(15)以及布置在两个主体之间并且具有直径(D1; D2)的两个环形垫圈(13; 14)之间的反压室(15)液压地产生的轴向推力平衡, 这是不同的。
