    • A coupling device (1) designed to be arranged downstream of an exhaust manifold (4) of an endothermic engine, including an internal liner (9), for example defined by a section of rigid pipe (25), a metal bellow (5) having two opposite cylindrical ends (7 and 8) without undulations, external shielding provide by a flexible hose (10) made of a helical stripwound metal element (11), if necessary fitted with a seal (23) between respective interconnected edges (13 and 14) of a metal strip (12), which forms the flexible shielding hose, and an insulating material (17) resistant to high temperatures and arranged to completely fill a radial gap (16) provided between the external stripwound metal hose (10) and the bellow (5). The ends (19 and 20) of the shielding hose (10) are welded to two terminal elements (21b and 22b) fixed to the cylindrical ends (7 and 8) of the bellow and radially protruding therefrom.
    • 一种联接装置(1),设计成布置在吸热发动机的排气歧管(4)的下游,包括内衬(9),例如由刚性管(25)的一部分限定的金属波纹管(5) 具有不具有起伏的两个相对的圆柱形端部(7和8),外部屏蔽通过由螺旋形的绕线金属元件(11)制成的柔性软管(10)提供,如果需要,则在相应的互连边缘(13和 形成柔性屏蔽软管的金属条(12)的上表面(14)和耐高温的绝缘材料(17),并布置成完全填充设置在外部金属软管(10)和 波纹管(5)。 屏蔽软管(10)的端部(19和20)焊接到固定到波纹管的圆柱端(7和8)并从其径向突出的两个端子元件(21b和22b)。
