Abstract

é descrita uma vedação de mancal de empuxo sem ventilação e tendo meios porosos. o mancal de empuxo tendo meios porosos pode incluir um mancal de empuxo primário com meios porosos, que também serve como um anel de vedação incluindo meios porosos, posicionado sobre uma câmara, e uma porta conectada à câmara, e passagens condutoras para comunicar fluido pressurizado para as câmaras através das portas do anel primário. o mancal de empuxo sem ventilação e com meios porosos também pode incluir um gás de processamento tratado fornecido à porta que fica mais próxima do gás de processamento não tratado, a uma pressão que é mais elevada do que o gás de processamento não tratado. um gás inerte (ou fluido em um estado líquido) pode ser fornecido à porta restante, a uma pressão igual à do gás de processamento não tratado. uma certa quantidade de gás de processamento tratado pode fluir em direção ao gás de processamento não tratado, e impedir que o gás não tratado entre na vedação de meios porosos.
