Abstract

<B>"DISPOSITIVO DE VEDAçãO DINâMICA EM LABIRINTO E MéTODO DE MONTAGEM"<D>. Um dispositivo de vedação dinâmica em labirinto, o qual inclui um estator possuindo um rebordo de engrenamento anular em uma porção radialmente interna do mesmo e um rotor possuindo um rebordo de engrenamento anular em uma porção radialmente externa do mesmo. O rebordo de engrenamento anular do estator e o rebordo de engrenamento anular do rotor possuem aberturas que se estendem radialmente e atuam em conjunto para entrefechar mecanicamente o estator e o rotor.
