Abstract

trata-se de funções conflitantes de vedação e lubrificação de faces deslizantes que são tornadas compatíveis em todo um período a partir do tempo de partida até o tempo de operação estável. fornece-se um par de partes deslizantes que deslizam relativamente umas sobre as outras, sendo que uma das partes deslizantes é um anel de vedação de lado estacionário, e a outra das partes deslizantes é um anel de vedação de lado giratório, sendo que os anéis de vedação têm, cada um, uma face deslizante s formada radialmente para vedar o fluido vedado contra vazamento, sendo que pelo menos uma das faces deslizantes s é dotada das ranhuras de introdução de fluido 10 configuradas para se comunicar com uma primeira borda periférica da face deslizante s e não se comunicar com uma segunda borda periférica, e é dotada de ranhuras de geração de pressão dinâmica 11 configuradas para se comunicar com a segunda borda periférica da face deslizante s e não se comunicar com a primeira borda periférica.
