Abstract
Patente de Invenção: <B>"MáQUINA CONDUTORA DE FLUIDO"<D>. A invenção refere-se a uma máquina condutora de fluido, especialmente bomba, com uma peça estrutural rotativa dentro de uma fenda anular em uma parte de corpo parado, sendo que a parte de corpo parado separa um espaço interior que apresenta uma pressão de produto maior de um espaço exterior qua apresenta uma pressão menor no qual a peça estrutural rotativa é apoiada em um apoio exterior que é vedado em relação ao espaço interior mediante um sistema de vedação. Para a melhoria da vedação, está sendo sugerido pela invenção que a fenda anular seja formada entre dois casquilhos de mancal de deslizamento que consistem em um material resistente ao desgaste, extremamente duro, que formam segundo o princípio ativo de um mancal de deslizamento radial um primeiro estágio de supressão de pressão, ao qual é ligado a jusante, no sentido axial, um dispositivo de retorno que retorna a fuga dente primeiro estágio de vedação ao processo de transporte da máquina hidráulica, ao qual, no sentido axial, é ligado um segundo estágio de vedação, configurado como vedação simples em forma de um lábio de anel de vedação e/ou de uma gaxeta anular corrediça simples.
