Abstract

Patente de Invenção: <B>"ANEL DE VEDAçãO EM FORMATO DE C"<D>. Uma vedação (30) inclui umas primeira e segunda curvaturas, axialmente opostas, integralmente, reciprocamente unidas (32, 34) através de uma trama (36) que se estende em conjunto, em um anel coletivo, possuindo uma fenda de circunferência. As duas curvaturas têm seção em forma de arco, com ancoragens de selamento radialmente internas e externas (40, 42, 44, 46). Além disso a trama (36) encontra-se disposta radialmente entre as ancoragens externa (40, 44) e interna (42, 46). As curvaturas (32, 34) encontram-se dispostas em sulcos correspondentes de membros adjacentes (24, 26) para concretizar uma vedação entre as mesmas e acomodar o movimento térmico diferencial radial e axial.
